Defines the SROS OAM ping Control Table for providing, via SNMP, the capability of performing SROS OAM ping test operations. The results of these tests are stored in the tnOamPingResultsTable and the tnOamPingHistoryTable.

Defines an entry in the tnOamPingCtlTable. The first index element, tnOamPingCtlOwnerIndex, is of type SnmpAdminString, a textual convention that allows for use of the SNMPv3 View-Based Access Control Model (RFC 2575 [11], VACM) and allows a management application to identify its entries. The second index, tnOamPingCtlTestIndex, enables the same management application to have multiple outstanding requests.

The test name index of the Nokia SROS OAM ping test. This is locally unique, within the scope of an tnOamPingCtlOwnerIndex.

This object allows entries to be created and deleted in the tnOamPingCtlTable. Deletion of an entry in this table results in all corresponding (same tnOamPingCtlOwnerIndex and tnOamPingCtlTestIndex index values) tnOamPingResultsTable and tnOamPingHistoryTable entries being deleted. Activation of a Nokia SROS OAM ping operation is controlled via tnOamPingCtlAdminStatus and not by changing this object's value to active(1). The values for configuration objects required for the type of test specified in tnOamPingCtlTestMode MUST be specified prior to a transition to active(1) state being accepted. Transitions in and out of active(1) state are not allowed while an entry's tnOamPingResultsOperStatus is active(1) with the exception that deletion of an entry in this table by setting its RowStatus object to destroy(6) will stop an active Nokia SROS OAM ping operation. The operational state of an Nokia SROS OAM ping operation can be determined by examination of its tnOamPingResultsOperStatus object.

The storage type for this conceptual row. Conceptual rows having the value 'permanent' need not allow write-access to any columnar objects in the row.

The purpose of this object is to provide a descriptive name of the OAM ping test.

See tnOamP2mpLspPingCtlTable for additional parameters. ethCfmLoopback - performs Ethernet Connectivity Fault Management (CFM) loopback tests. This MIB supports the SAA form of this test only (the OAM form uses a separate set of objects - see IEEE8021-CFM-MIB). Additional parameters for the SAA ethCfmLoopback test are in tnOamEthCfmPingCtlTable. ethCfmTwoWayDelay - performs Ethernet Connectivity Fault Management (CFM) two way delay tests. This MIB supports the SAA form of this test only (the OAM form uses a separate set of objects - see IEEE8021-CFM-MIB). Additional parameters for the SAA ethCfmTwoWayDelay test are in tnOamEthCfmPingCtlTable. mobGtpPing - Tests GTP (GPRS Tunnelling Protocol) path connectivity. ethCfmTwoWaySlm - performs Ethernet Connectivity Fault Management (CFM) two way Synthetic Loss Measurement (SLM) tests. This MIB supports the SAA form of this test only (the OAM form uses a separate set of objects - see TN-IEEE8021-CFM-MIB). Additional parameters for the SAA ethCfmTwoWaySlm test are in tnOamEthCfmPingCtlTable. Enumeration: 'ethCfmTwoWaySlm': 22, 'p2mpLspPing': 18, 'mrInfo': 13, 'macPurge': 7, 'icmpPing': 15, 'macPopulate': 6, 'svcPing': 3, 'macPing': 5, 'cpePing': 12, 'vccvPing': 14, 'atmPing': 10, 'ethCfmTwoWayDelay': 20, 'vprnPing': 9, 'mobGtpPing': 21, 'dnsPing': 16, 'mfibPing': 11, 'mtuPing': 2, 'ancpLoopback': 17, 'ethCfmTwoWayLm': 23, 'none': 0, 'lspPing': 8, 'ethCfmLoopback': 19, 'sdpPing': 1.

Reflects the desired state that a tnOamPingCtlEntry should be in: enabled(1) - Attempt to activate the test as defined by this tnOamPingCtlEntry. disabled(2) - Deactivate the test as defined by this tnOamPingCtlEntry. An attempt to set tnOamPingCtlAdminStatus to 'enabled' will fail if the parameters required by a particular OAM ping test mode have not been previously set. Upon completion of an OAM ping test, the agent will reset the value of this object to 'disabled'. When this object has the value 'enabled' an attempt to modify any of the test parameters will fail with an inconsistentValue error. If tnOamPingCtlTestMode equals either 'sdpPing' or 'mtuPing', tnOamPingCtlOrigSdpId must have already been set. If tnOamPingCtlTestMode equals 'mtuPing', tnOamPingCtlMtuStartSize and tnOamPingCtlMtuEndSize must also have already been set. If tnOamPingCtlTestMode equals 'svcPing', tnOamPingCtlTgtAddress and tnOamPingCtlServiceId must have already been set. If tnOamPingCtlTestMode equals 'cpePing', tnOamPingCtlTgtAddress, and tnOamCpePingCtlSourceIpAddr are required. If tnOamPingCtlTestMode equals 'icmpPing', tnOamPingCtlTgtAddress must have already been set. If tnOamPingCtlTestMode equals 'dnsPing', tnOamPingCtlTgtAddress must have already been set. If tnOamPingCtlSAA has the value 'true' and tnOamSaaCtlAdminStatus has a value 'outOfService', an attempt to set this object to 'enabled' will fail with an inconsistentValue error. Refer to the corresponding tnOamPingResultsOperStatus to determine the operational state of the test defined by this entry. Enumeration: 'disabled': 2, 'enabled': 1.

Specifies the originating SDP-ID to be used for performing a sdp-ping or mtu-ping operation. This parameter is required only if tnOamPingCtlTestMode has a value of either 'sdpPing' or 'mtuPing'. The far-end address of the specified SDP-ID is the expected responder-id within each OAM reply message received. The specified SDP-ID defines the encapsulation of the SDP tunnel encapsulation used to reach the far-end. This can be IP/GRE or MPLS. The value of tnOamPingCtlFcName is used to define the outgoing forwarding class used for the SDP encapsulation. If the value of tnOamPingCtlOrigSdpId is invalid, or the SDP is administratively down, or unavailable, the OAM Echo request message probe is not sent and an appropriate error value is written to tnOamPingHistoryStatus for that probe entry. Once the interval timer expires, the next probe attempt will be made if required.

Specifies the return SDP-ID to be used by the far-end node for its message reply. This parameter is optional and is valid only if tnOamPingCtlTestMode has a value of 'sdpPing'. If this SDP-ID does not exist on the far-end, terminates on another node different than the originating node, or some other issue prevents the far-end from using the specified SDP-ID, the OAM Echo message reply is sent using generic IP/GRE OAM encapsulation. The received forwarding class (as mapped on the ingress network interface for the far-end) defines the forwarding class encapsulation for the reply message.

The value of tnOamPingCtlFcName specifies the forwarding class to be used when launching the probe(s). The forwarding class name must be present in the index column of TIMETRA-QOS-MIB::tFCNameTable. This object is optional. As shown in the following table a) this object is applicable to a subset of the test types, and b) the default forwarding class depends on the test type. tnOamPingCtlTestMode Applicable? Default ---------------------- ----------- ------- 'cpePing' yes 'be' 'ethCfmLoopback' yes 'nc' 'ethCfmTwoWayDelay' yes 'nc' ethCfmTwoWaySlm' yes 'nc' 'icmpPing' yes 'nc' 'lspPing' yes 'be' 'macPing' yes 'be' 'p2mpLspPing' yes 'be' 'sdpPing' yes 'be' 'vccvPing' yes 'be' 'vprnPing' yes 'be' otherwise no N/A For 'ethCfmLoopback','ethCfmTwoWayDelay', and 'ethCfmTwoWaySlm', the forwarding class depends on whether the request is configured to egress on a network port or an access port. In the network port case, the forwarding class is the forwarding class of the pseudowire. In the access port case, the forwarding class is that of the SAP's egress encapsulation policy. For 'lspPing' this is the forwarding class of the LSP tunnel. For 'macPing' or 'sdpPing' this is the forwarding class of the SDP encapsulation. For 'p2mpLspPing' this is the forwarding class of the P2MP LSP tree. For 'vccvPing' this is the forwarding class of the pseudowire. If forwarding classes are mapped by the applicable QoS policy, the probe(s) may be launched using a different forwarding class than the forwarding class specified by this object.

The value of tnOamPingCtlProfile specifies the profile to be used with the forwarding class specified in tnOamPingCtlFcName. This object is optional. As shown in the following table a) this object is applicable to a subset of the test types, and b) the default profile value depends on the test type. tnOamPingCtlTestMode Applicable? Default ---------------------- ----------- ------- 'cpePing' yes 'out(2)' 'ethCfmLoopback' yes 'in(1)' 'ethCfmTwoWayDelay' yes 'in(1)' 'ethCfmTwoWaySlm' yes 'in(1)' 'icmpPing' no N/A 'lspPing' yes 'out(2)' 'macPing' yes 'out(2)' 'p2mpLspPing' yes 'out(2)' 'sdpPing' yes 'out(2)' 'vccvPing' yes 'out(2)' 'vprnPing' yes 'out(2)' otherwise no N/A

The value of tnOamPingCtlMtuStartSize specifies the size of the first OAM Echo message sent as part of an 'mtuPing' test. Setting this object to a non-zero value is a prerequisite for starting an 'mtuPing' test. Its value must be less than or equal to the value of tnOamPingCtlMtuEndSize. An attempt to set this object from a non-zero value to zero will fail with a wrongValue error. Changing the message size is a method of checking the ability of an SDP to support a particular path-mtu value. The size of the message does not include the SDP encapsulation, VC-Label (if applied) or any DLC headers or trailers.

The value of tnOamPingCtlMtuEndSize specifies the size of the last OAM Echo message sent as part of an 'mtuPing' test. Setting this object to a non-zero value is a prerequisite for starting an 'mtuPing' test. Its value must be greater than or equal to the value of tnOamPingCtlMtuStartSize. An attempt to set this object from a non-zero value to zero will fail with a wrongValue error.

Specifies the number of octets by which to increment the OAM Echo message request size for each message request sent when tnOamPingCtlTestMode is set equal to 'mtuPing'. If the next incremented message size is greater than tnOamPingCtlMtuEndSize, the last message has already been sent. The next size message is not sent until a reply is received or three messages have timed out at the current size. This parameter is optional.

Specifies the Ipv4 address to be used as the destination for performing an OAM ping operation when tnOamPingCtlTestMode has a value of 'svcPing' or 'vprnPing'. This parameter is required for 'svcPing', 'vprnPing', 'cpePing' and 'mrinfo'. This object was obsoleted in release 4.0 and replaced with InetAddress objects tnOamPingCtlTgtAddrType and tnOamPingCtlTgtAddress.

The value of tnOamPingCtlServiceId specifies the service ID of the service being tested. The applicability of tnOamPingCtlServiceId varies with the test type, as shown in the following table. tnOamPingCtlTestMode Applicability Related Virtual Router Object ---------------------- ------------- ----------------------------- 'cpePing' mandatory none 'icmpPing' optional tnOamPingCtlVRtrID 'macPing' mandatory none 'macPopulate' mandatory none 'macPurge' mandatory none 'mfibPing' mandatory none 'mrInfo' optional tnOamPingCtlVRtrID 'svcPing' mandatory none 'vprnPing' mandatory none otherwise not applicable none When tnOamPingCtlServiceId is mandatory, a non-zero value must be provided. When tnOamPingCtlServiceId is optional, it is used to specify a VPRN service. The test must use the VPRN service's virtual router. When a related virtual router object is shown, the interaction is described in the DESCRIPTION clause of the listed object. Service IDs larger than 2147483647 are internal, so they are excluded from the range. The default value is the null service ID.

When the value of tnOamPingCtlLocalSdp is 'true', the 'svcPing' test determines an egress SDP-ID that is bound to the service that has the far-end IP address specified in tnOamPingCtlTgtAddress assigned to it. The far-end address of the specified SDP-ID is the expected responder-id within the OAM Echo reply message. The SDP-ID defines the encapsulation of the SDP tunnel encapsulation used to reach the far-end. This can be IP/GRE or MPLS. On the originator egress, the Service-ID must have an associated VC-Label to reach the far-end address of the SDP-ID and the SDP-ID must be operational for the message to be sent. This object is optional and valid only when tnOamPingCtlTestMode is equal to 'svcPing'.

The value of tnOamPingCtlRemoteSdp specifies the encapsulation of the ping reply to be sent by the far end node. When tnOamPingCtlRemoteSdp is 'false', the far-end node sends the reply using the generic IP/GRE OAM encapsulation. When tnOamPingCtlRemoteSdp is 'true', the far-end node sends the reply using the same service tunnel encapsulation labeling used for the associated service traffic. If that labeling cannot be found, the generic IP/GRE OAM encapsulation is used. This object is optional and is applicable only when tnOamPingCtlTestMode is equal to 'svcPing'.

The value of tnOamPingCtlSize specifies the size of the OAM Echo message. This parameter is optional and is valid only if tnOamPingCtlTestMode has a value of 'sdpPing', 'macPing', 'lspPing', 'vprnPing', 'mfibPing', 'vccvPing', 'icmpPing', 'p2mpLspPing', 'ethCfmLoopback' or 'ethCfmTwoWaySlm'. The minimum, maximum, and default values for the tnOamPingCtlTestMode cases are: 'ethCfmLoopback' : 0, 1500, 0 'ethCfmTwoWaySlm': 0, 1500, 0 'ethCfmTwoWayDelay': 0, 1500, 0 'icmpPing' : 0, 16384, 56 'lspPing' : 80, 9198, 80 - LSP prefix specified : 92, 9198, 92 - LSP name specified 'macPing' : 1, 9198, 72 'mfibPing' : 1, 9198, 72 'p2mpLspPing' : 92|97, 9198, 92 - LSP name, 0 S2L specified : 104|109, 9198, 104 - LSP name, 1 S2L specified : 112|117, 9198, 112 - LSP name, 2 S2L specified : 120|125, 9198, 120 - LSP name, 3 S2L specified : 128|133, 9198, 128 - LSP name, 4 S2L specified : 136|141, 9198, 136 - LSP name, 5 S2L specified : 88|93, 9198, 88 - LDP id, 0 leaf-addr specified : 100|105, 9198, 100 - LDP id, 1 leaf-addr specified : 108|113, 9198, 108 - LDP id, 2 leaf-addr specified : 116|121, 9198, 116 - LDP id, 3 leaf-addr specified : 124|129, 9198, 124 - LDP id, 4 leaf-addr specified : 132|137, 9198, 132 - LDP id, 5 leaf-addr specified : 92|97, 9198, 92 - LDP SSM, 0 leaf-addr specified : 104|109, 9198, 104 - LDP SSM, 1 leaf-addr specified : 112|117, 9198, 112 - LDP SSM, 2 leaf-addr specified : 120|125, 9198, 120 - LDP SSM, 3 leaf-addr specified : 128|133, 9198, 128 - LDP SSM, 4 leaf-addr specified : 136|141, 9198, 136 - LDP SSM, 5 leaf-addr specified 'sdpPing' : 72, 9198, 72 'vccvPing' : 88, 9198, 88 - FEC 128 pseudowire : 120, 9198, 120 - FEC 129 pseudowire 'vprnPing' : 1, 9198, 72 An RSVP-TE P2MP LSP consists of source-to-leaf (S2L) sub-LSPs. For P2MP LSP ping, a gap in the supported range of tnOamPingCtlSize arises from the inclusion of the Pad TLV (see RFC 4379 section 3.4). For example, when no S2L sub-LSP is specified for a RSVP P2MP LSP, the minimum ping size is 92. But the next valid minimum ping size is 97 due to the inclusion of the Pad TLV. When the OAM message is encapsulated in an IP/GRE SDP, the IP 'DF' (Don't Fragment) bit is set. If any segment of the path between the sender and receiver cannot handle the message size, the message is discarded. MPLS LSPs are not expected to fragment the message either, as the message contained in the LSP is not an IP packet. When tnOamPingCtlTestMode has a value of 'ethCfmLoopback' or 'ethCfmTwoWaySlm', the value of this object specifies the number of octets in the Value field of the Data TLV of the Ethernet CFM packet. If zero is specified, the packet has no Data TLV. When tnOamPingCtlTestMode has a value of 'icmpPing', the value of this object specifies the payload size following the ICMP header. When tnOamPingCtlTestMode has a value of 'mtuPing', changing the message size is a method of checking the ability of an SDP to support a particular path-mtu value. The size of the message does not include the SDP encapsulation, VC-Label (if applied) or any DLC headers or trailers. Before 6.0 release, the minimum size in 'sdpPing' is 40 octets. Such shorter packet has no timestamp information but should still be accepted for interoperability purpose. However, new 'sdpPing' should include the timestamp information.

The value of tnOamPingCtlTimeOut specifies the time-out value, in milliseconds, to be used during a test run. Timers (with duration configured using the tnOamPingCtlTimeOut value) are used in one of two ways during a test run. 1. Per Probe: a timer is started each time a probe is sent. If the timer expires before the probe response arrives, the probe is declared failed. This is the traditional time-out method for a sequence of probes. OR 2. Per Test: a timer is started once per test run, when the last probe of the test run is sent. ANY probe which does not have a response when the timer expires is declared failed. 'Per Probe' or 'Per Test' is chosen based on the tnOamPingCtlTestMode value. The choice is not configurable. The accepted minimum, maximum, and default values for tnOamPingCtlTimeOut depend on tnOamPingCtlTestMode, as shown in the following table in seconds. The table also shows the timer usage for the test mode. tnOamPingCtlTestMode Min Max Def Timer Usage ---------------------- --- --- --- ----------- 'atmPing' 1 10 5 Per Probe 'dnsPing' 1 120 5 Per Probe 'ethCfmLoopback' 1 10 5 Per Probe 'ethCfmTwoWayDelay' 1 10 5 Per Test 'ethCfmTwoWaySlm' 1 10 5 Per Test 'icmpPing' 1 10 5 Per Test 'lspPing' 1 10 5 Per Probe 'macPing' 1 10 5 Per Probe 'mfibPing' 1 100 5 Per Probe 'mtuPing' 1 10 5 Per Probe 'p2mpLspPing' 1 120 10 Per Probe 'sdpPing' 1 10 5 Per Probe 'vccvPing' 1 10 5 Per Probe 'vprnPing' 1 100 5 Per Probe otherwise ......... the value of tnOamPingCtlTimeOut is irrelevant

The value of tnOamPingCtlProbeCount specifies the number of probes to send during the test. The maximum probe count depends on the value of tnOamPingCtlTestMode, as follows: 'macPopulate', 'macPurge','p2mpLspPing', 'svcPing' : 1 'ethCfmTwoWayDelay', 'ethCfmTwoWaySlm' : 1000 'icmpPing' : 100000 otherwise : 100 For the following tnOamPingCtlTestMode values, the value of tnOamPingCtlProbeCount does not affect the behavior of the test: 'mrInfo', 'mtuPing'. If tnOamPingCtlTestMode is 'icmpPing', the default probe count value is 5. Otherwise, the DEFVAL applies.

The value of tnOamPingCtlInterval specifies the time to wait between the transmission of one OAM Echo request and the next. The applicability, range, and default value of the interval specified using the tnOamPingCtlInterval vary with tnOamPingCtlTestMode and tnOamIcmpPingCtlRapid, as shown in the following table in seconds. tnOamPingCtlTestMode Supported Values (sec) Default (sec) 'ethCfmLoopback' 1, 2, .. 10 5 'ethCfmTwoWayDelay' 0.1, 0.2, .. 0.9; 1, 2, .. 10 5 'ethCfmTwoWaySlm' 0.1, 0.2, .. 0.9; 1, 2, .. 10 5 'icmpPing' with RAPID 0.01, 0.02, .. 100.00 0.01 'icmpPing' without RAPID 1, 2, .. 10000 1 'p2mpLspPing' not applicable otherwise 1, 2, .. 10 1

The maximum number of entries allowed in the tnOamPingHistoryTable for this OAM ping test. The agent will remove the oldest entry in the tnOamPingHistoryTable to allow the addition of an new entry once the number of rows in the tnOamPingHistoryTable reaches this value. Old entries are not removed when a new test is started. Entries are added to the tnOamPingHistoryTable until tnOamPingCtlMaxRows is reached before entries begin to be removed. 'p2mpLspPing' uses a default value of 400, which is the maximum number of leaves per P2MP LSP tree. A value of 0 for this object disables creation of tnOamPingHistoryTable entries. This object was obsoleted in release 6.0R17.

The value of tnOamPingCtlTrapGeneration specifies the notification(s) to send for a test run. Each bit enables the transmission of one notification, as follows. 'probeFailure(0)': send one tnOamPingProbeFailedV3 notification if at least M successive probes failed during the test run. M is configured using tnOamPingCtlTrapProbeFailureFilter. 'testFailure(1)': send one tnOamPingTestFailedV3 notification if at least N probes failed during the test run. N is configured using tnOamPingCtlTrapTestFailureFilter. 'testCompletion(2)': send one tnOamPingTestCompletedV3 notification when the test run is complete. Bits: 'testCompletion': 2, 'testFailure': 1, 'probeFailure': 0.

The value of this object is used to determine when to generate a tnOamPingProbeFailed NOTIFICATION. Setting tnOamPingCtlTrapGeneration to 'probeFailure (0)' implies that a tnOamPingProbeFailed NOTIFICATION is generated only when the number of successive probe failures, as indicated by the value of tnOamPingCtlTrapProbeFailureFilter, fail within a given ping test.

The value of this object is used to determine when to generate a tnOamPingTestFailed NOTIFICATION. Setting tnOamPingCtlTrapGeneration to 'testFailure (1)' implies that a tnOamPingTestFailed NOTIFICATION is generated only when the number of ping failures within a test exceed the value of tnOamPingCtlTrapTestFailureFilter.

The value of tnOamPingCtlSAA specifies if this test is an SAA test (Service Assurance Agent; 'true'), or an OAM test ('false'). If there is a tnOamSaaCtlTable row with the specified index values, 'true' is returned. Otherwise, 'false' is returned.

The value of tnOamPingCtlRuns indicates the number of times this OAM ping test has been executed.

The value of tnOamPingCtlFailures indicates the number of times this OAM ping test has failed.

The value of tnOamPingCtlLastRunResult indicates the completion status the last time this test was executed. If this OAM test is currently in progress, this object indicates the result of the previous test run, if any.

The value of tnOamPingCtlLastChanged indicates the time the value of a settable object in this row was last changed.

The value of tnOamPingCtlVRtrID specifies the virtual router to be used for the test. The value specified must be the index of an active row in TIMETRA-VRTR-MIB::vRtrConfTable. This object is applicable if tnOamPingCtlTestMode is 'icmpPing' or 'mrInfo'. When directing an 'icmpPing' or 'mrInfo' test to use a virtual router associated with a VPRN service, the virtual router can be specified using tnOamPingCtlVRtrID (with the VPRN's virtual router number) or tnOamPingCtlServiceId (with the VPRN's service number). tnOamPingCtlServiceId is preferred, because service numbers are constant across an SROS reboot (while virtual routers may be renumbered). If non-default values are specified for both tnOamPingCtlVRtrID and tnOamPingCtlServiceId, tnOamPingCtlServiceId is used. Setting this object is optional.

The value of tnOamPingCtlTgtAddrType specifies the address type of tnOamPingCtlTgtAddress. Values supported depend on tnOamPingCtlTestMode, as follows. 'cpePing ': 'ipv4(1)' 'dnsPing' : 'ipv4(1)' 'ipv6(2)' 'icmpPing': 'ipv4(1)' 'ipv6(2)' 'ipv6z(4)' 'dns(16)' 'mfibPing': 'ipv4(1)' 'ipv6(2)' 'mrInfo ': 'ipv4(1)' 'dns(16)' 'svcPing' : 'ipv4(1)' 'vccvPing': 'unknown(0)' 'ipv4(1)' 'vprnPing': 'ipv4(1)' 'ipv6(2)' otherwise : 'unknown(0)'

The value of tnOamPingCtlTgtAddress specifies the destination IP host address to be used when performing an OAM ping operation. The corresponding address type is configured using tnOamPingCtlTgtAddrType. For 'dnsPing' this is the address of the DNS server host that will be asked to resolve a dns name specified by tnOamPingCtlDnsName.

The value of tnOamPingCtlSrcAddrType specifies the address type of tnOamPingCtlSrcAddress. Only 'ipv4' and 'ipv6' address types are supported.

The value of tnOamPingCtlSrcAddress specifies the source IP host address to be used when performing an OAM ping operation. The corresponding address type is configured using tnOamPingCtlSrcAddrType. This is an optional parameter. It is used when tnOamPingCtlTestMode is 'icmpPing', 'dnsPing', 'lspPing', 'p2mpLspPing' (LDP), or 'vccvPing'.

The value of tnOamPingCtlDnsName specifies the DNS name to be resolved to an IP address. This object is required for 'dnsPing'.

The value of tnOamPingCtlDNSRecord specifies which DNS record is to be retrieved in this test. Enumeration: 'ipv4Arecord': 1, 'ipv6AAAArecord': 2.

The value of tnOamPingCtlIntervalUnits specifies the units for tnOamPingCtlInterval. For example, if tnOamPingCtlIntervalUnits has the value 'centiseconds(2)', and tnOamPingCtlInterval has the value 10, the test's interval is 0.1 seconds. The supported combinations of tnOamPingCtlIntervalUnits, tnOamPingCtlInterval, tnOamPingCtlTestMode, and tnOamIcmpPingCtlRapid are specified in the tnOamPingCtlInterval DESCRIPTION clause. The interaction between this object and tnOamIcmpPingCtlRapid is specified in the tnOamIcmpPingCtlRapid DESCRIPTION clause. Enumeration: 'seconds': 1, 'centiseconds': 2.

Defines the OAM Ping Results Table for providing the capability of performing OAM ping operations.

The value of tnOamVccvPingCtlMplsTpGlobalId specifies the target MPLS-TP Global Identifier to be used for the test. The supported object combinations for VCCV ping tests are listed in the tnOamVccvPingCtlTable DESCRIPTION clause.

The value of tnOamVccvPingCtlMplsTpNodeId specifies the target MPLS-TP Node Identifier to be used for the test. A value of zero indicates that no Node Identifier has been configured. The supported object combinations for VCCV ping tests are listed in the tnOamVccvPingCtlTable DESCRIPTION clause.

The value of tnOamVccvPingCtlTestSubMode specifies the type of VCCV ping test to perform. When this object is 'unspecified(1)', the type of VCCV ping test to be performed is determined when the test is started, from the set of tnOamVccvPingCtlTable objects configured with non-default values. If there is a mismatch between tnOamVccvPingCtlTestSubMode and the type of the pseudowire to be tested, the test will fail. For example, if tnOamVccvPingCtlTestSubMode is 'static(2)', and tnOamVccvPingCtlSdpIdVcId refers to an SDP binding with TIMETRA-SDP-MIB::sdpDelivery not equal to 'mplsTp(3)', the test will fail. The supported object combinations for VCCV ping tests are listed in the tnOamVccvPingCtlTable DESCRIPTION clause.

The value of tnOamVccvPingCtlAssocChannel specifies the launched echo request's usage of the Associated Channel (ACH) mechanism, when performing an MPLS-TP VCCV ping test. When tnOamVccvPingCtlTestSubMode is 'static(2)', the default value for tnOamVccvPingCtlAssocChannel is 'nonIp(2)'. The supported object combinations for VCCV ping tests are listed in the tnOamVccvPingCtlTable DESCRIPTION clause.

tnOamEthCfmPingCtlTable contains Ethernet CFM-specific configuration information for 'ethCfmLoopback', 'ethCfmTwoWayDelay', and 'ethCfmTwoWaySlm' tests. This table extends the tnOamPingCtlTable. A row is automatically created in this table when a row is created in tnOamPingCtlTable with tnOamPingCtlTestMode set to 'ethCfmLoopback', 'ethCfmTwoWayDelay', or 'ethCfmTwoWaySlm'. Deleting a row in tnOamPingCtlTable automatically deletes the row (if any) with the same index values in tnOamEthCfmPingCtlTable. Test results are stored in tnOamPingResultsTable and tnOamPingHistoryTable.

tnOamEthCfmPingCtlEntry defines an entry in the tnOamEthCfmPingCtlTable. Each index is an object in tnOamPingCtlTable.

The value of tnOamEthCfmPingCtlTgtMacAddr specifies the target MAC address for the test.

The value of tnOamEthCfmPingCtlSrcMdIndex specifies the source CFM maintenance domain index for the test. Zero is the null CFM maintenance domain index.

The value of tnOamEthCfmPingCtlSrcMaIndex specifies the source CFM maintenance association index for the test. Zero is the null CFM maintenance association index.

The value of tnOamEthCfmPingCtlSrcMepId specifies the source Maintenance association End Point Identifier (MEP ID) for the test. Zero is the null MEP ID.

Defines the Nokia SROS OAM Trace Route Control Table for providing the capability of invoking OAM trace route tests from SNMP. The results of trace route operations can be stored in the tnOamTrResultsTable, tnOamTrProbeHistoryTable, and the tnOamTrHopsTable.

Defines an entry in the tnOamTrCtlTable. The first index element, tnOamTrCtlOwnerIndex, is of type SnmpAdminString, a textual convention that allows for use of the SNMPv3 View-Based Access Control Model (RFC 2575 [11], VACM) and allows an management application to identify its entries. The second index, tnOamTrCtlTestIndex (also an SnmpAdminString), enables the same management application to have multiple requests outstanding.

The test name index of a Nokia SROS OAM Trace Route test. This is locally unique, within the scope of a tnOamTrCtlOwnerIndex.

This object allows entries to be created and deleted in the tnOamTrCtlTable. Deletion of an entry in this table results in all corresponding (same tnOamTrCtlOwnerIndex and tnOamTrCtlTestIndex index values) tnOamTrResultsTable, tnOamTrProbeHistoryTable, and tnOamTrHopsTable entries being deleted. The values for configuration objects required for the type of test specified in tnOamTrCtlTestMode MUST be specified prior to a transition to active(1) state being accepted. Activation of an Nokia SROS OAM Trace Route operation is controlled via tnOamTrCtlAdminStatus and not by transitioning of this object's value to active(1). Transitions in and out of active(1) state are not allowed while an entry's tnOamTrResultsOperStatus is active(1) with the exception that deletion of an entry in this table by setting its RowStatus object to destroy(6) will stop an active Nokia SROS OAM Trace Route operation. The operational state of an Nokia SROS OAM Trace Route operation can be determined by examination of the corresponding tnOamTrResultsOperStatus object.

The storage type for this conceptual row. Conceptual rows having the value 'permanent' need not allow write-access to any columnar objects in the row.

The purpose of this object is to provide a descriptive name of the Nokia SROS OAM Trace Route test.

Specifies the type of Nokia SROS OAM Trace Route test defined by this entry. The configuration parameters unique to a specific test type are to be found in a sparsely dependent extension table for that test type. p2mpLspTrace is supported for non-SAA tests only. ethCfmLinkTrace is supported for SAA tests only. This is a required parameter. Enumeration: 'none': 0, 'vprnTraceRoute': 3, 'ldpTreeTrace': 6, 'mcastTraceRoute': 4, 'macTraceRoute': 1, 'ethCfmLinkTrace': 9, 'vccvTraceRoute': 7, 'lspTraceRoute': 2, 'icmpTraceRoute': 5, 'p2mpLspTrace': 8.

Reflects the desired state that a tnOamTrCtlEntry should be in: enabled(1) - Attempt to activate the test as defined by this tnOamTrCtlEntry. disabled(2) - Deactivate the test as defined by this tnOamTrCtlEntry. If tnOamTrCtlSAA has the value 'true' and tnOamSaaCtlAdminStatus has the value 'outOfService', an attempt to set this object to 'enabled' will fail with an inconsistentValue error. Refer to the corresponding tnOamTrResultsOperStatus to determine the operational state of the test defined by this entry. Enumeration: 'disabled': 2, 'enabled': 1.

The value of tnOamTrCtlFcName specifies the forwarding class to be used when launching the probe(s). The forwarding class name must be present in the index column of TIMETRA-QOS-MIB::tFCNameTable. This object is optional. As shown in the following table a) this object is applicable to a subset of the test types, and b) the default forwarding class depends on the test type. tnOamTrCtlTestMode Applicable? Default -------------------- ----------- ------- ethCfmLinkTrace yes 'nc' ldpTreeTrace yes 'be' lspTraceRoute yes 'be' macTraceRoute yes 'be' p2mpLspTrace yes 'be' vccvTraceRoute yes 'be' vprnTraceRoute yes 'be' otherwise no N/A For 'ethCfmLinkTrace', the forwarding class depends on whether the request is configured to egress on a network port or an access port. In the network port case, the forwarding class is the forwarding class of the pseudowire. In the access port case, the forwarding class is that of the SAP's egress encapsulation policy. For 'lspTraceRoute' this is the forwarding class of the LSP tunnel. For 'macTraceRoute' this is the forwarding class of the SDP encapsulation. For 'p2mpLspTrace' this is the forwarding class of the P2MP LSP tree. If forwarding classes are mapped by the applicable QoS policy, the probe(s) may be launched using a different forwarding class than the forwarding class specified by this object.

The value of tnOamTrCtlProfile specifies the profile to be used with the forwarding class specified in tnOamTrCtlFcName. This object is optional. As shown in the following table a) this object is applicable to a subset of the test types, and b) the default profile value depends on the test type. tnOamTrCtlTestMode Applicable? Default -------------------- ----------- ------- ethCfmLinkTrace yes 'in(1)' ldpTreeTrace yes 'out(2)' lspTraceRoute yes 'out(2)' macTraceRoute yes 'out(2)' p2mpLspTrace yes 'out(2)' vccvTraceRoute yes 'out(2)' vprnTraceRoute yes 'out(2)' otherwise no N/A

Specifies the Ipv4 address to be used as the destination for performing an OAM Trace Route operation. This parameter is not used by 'macTraceRoute' or 'lspTraceRoute' or 'mcastTraceRoute'. This parameter is required by 'vprnTraceRoute'. This object was obsoleted in release 4.0 and replaced with InetAddress objects tnOamTrCtlTgtAddrType and tnOamTrCtlTgtAddress.

The value of tnOamTrCtlServiceId specifies the service ID of the service being tested. The applicability of tnOamTrCtlServiceId varies with the test type, as shown in the following table. tnOamTrCtlTestMode Applicability Related Virtual Router Object -------------------- ------------- ----------------------------- 'icmpTraceRoute' optional tnOamTrCtlVRtrID 'macTraceRoute' mandatory none 'mcastTraceRoute' optional tnOamMcastTrCtlVRtrID 'vprnTraceRoute' mandatory none otherwise not applicable none When tnOamTrCtlServiceId is mandatory, a non-zero value must be provided. When tnOamTrCtlServiceId is optional, it is used to specify a VPRN service. The test must use the VPRN service's virtual router. When a related virtual router object is shown, the interaction is described in the DESCRIPTION clause of the listed object. Service IDs larger than 2147483647 are internal, so they are excluded from the range. The default value is the null service ID.

The value of tnOamTrCtlDataSize specifies the size of the data portion of the Trace Route request, in octets. The size of the message does not include the SDP encapsulation, VC-Label (if applied) or any DLC headers or trailers. This parameter is optional. When the OAM message is encapsulated in an IP/GRE SDP, the IP 'DF' (Don't Fragment) bit is set. If any segment of the path between the sender and receiver cannot handle the message size, the message is discarded. MPLS LSPs are not expected to fragment the message either, as the message contained in the LSP is not an IP packet. When the data size is specified as 1, it is interpreted as the minumum valid data size for the trace type. The minimum data size (in octets) varies with tnOamTrCtlTestMode, as follows: 'lspTraceRoute' with multipath DSMap 140 'lspTraceRoute' otherwise 104 'macTraceRoute' 1 'p2mpLspTrace' 132 'vccvTraceRoute', FEC 128 pseudowire 88 'vccvTraceRoute', FEC 129 pseudowire 120 'vprnTraceRoute' 1 This parameter is not used by 'ethCfmLinkTrace', 'icmpTraceRoute', 'ldpTreeTrace', or 'mcastTraceRoute'.

Specifies the time-out value, in seconds, for an Nokia SROS OAM Trace Route request. This parameter is optional. For 'ethCfmLinkTrace', this is the time out for the whole test. The minimum, maximum, and default values of this object vary with tnOamTrCtlTestMode, as follows: 'icmpTraceRoute' : N/A N/A N/A 'ethCfmLinkTrace': 1 10 5 otherwise : 1 60 3 If tnOamTrCtlTestMode is 'ethCfmLinkTrace', the value of tnOamTrCtlTimeOut must be less than or equal to the value of tnOamTrCtlInterval.

Specifies the number of times to reissue an Nokia SROS OAM Trace Route request with the same time-to-live (TTL) value. This parameter is optional. This parameter is not configurable for 'icmpTraceRoute'; a default value of 3 is used.

The value of tnOamTrCtlMaxTtl specifies the maximum time-to-live value. This parameter is optional. When tnOamTrCtlMaxTtl is not explicitly specified, the agent defaults the value based on the 'tnOamTrCtlTestMode'. In the case of 'lspTraceRoute' the default is set to 30. In the case of 'icmpTraceRoute' the default is set to 30. In the case of 'ldpTreeTrace' the default is set to 30. In the case of 'vccvTraceRoute' the default is set to 8. In the case of 'p2mplspTrace' the default is set to 30. In the case of 'ethCfmLinkTrace' the default is set to 64. Otherwise the default is set to 4.

The value of tnOamTrCtlInitialTtl specifies the initial TTL value to use. This enables bypassing the initial (often well known) portion of a path. This parameter is optional. This parameter is not configurable for 'icmpTraceRoute'; the default value 1 is used. This parameter is not used with 'ethCfmLinkTrace'.

The value of tnOamTrCtlDSField specifies the value to load in the Type of Service (TOS) octet or the Traffic Class (TC) octet of the launched ICMP echo request(s). The TOS octet is a field in the IPv4 packet header. The TC octet is a field in the IPv6 packet header. The value in the TOS or TC octet may influence the route, latency, and/or probability of loss for the echo request (and, by inference, for the associated data flow). This object is supported when tnOamTrCtlTestMode is 'icmpTraceRoute'. Otherwise, it is ignored. This object is optional.

The value of tnOamTrCtlMaxFailures specifies the maximum number of consecutive timeouts allowed before terminating a trace route test. This object is optional. As shown in the following table a) this object is applicable to a subset of the test types, and b) the default value and upper bound depend on the test type. tnOamTrCtlTestMode Applicable? Default Upper Bound -------------------- ----------- ------- ----------- 'icmpTraceRoute' yes 90 90 'lspTraceRoute' yes 5 255 'p2mpLspTrace' yes 5 10 'vccvTraceRoute' yes 5 255 otherwise no N/A N/A In the 'icmpTraceRoute' case, changing the tnOamTrCtlMaxFailures value away from the default is not supported.

The value of tnOamTrCtlInterval specifies the number of seconds to wait before repeating an Nokia SROS OAM Trace Route test as defined by the value of the various objects in the corresponding row. This parameter is optional. The number of hops in a single Nokia SROS OAM Trace Route test is determined by the value of the corresponding tnOamTrCtlProbesPerHop object. After a single test completes, the number of seconds as defined by the value of tnOamTrCtlInterval MUST elapse before the next Nokia SROS OAM Trace Route test is started. The applicability, range, and default value of this object vary with tnOamTrCtlTestMode, as shown in the following table. tnOamTrCtlTestMode Min Max Default 'ethCfmLinkTrace' 1 10 5 'icmpTraceRoute' not applicable 'vccvTraceRoute' 1 255 1 otherwise 1 10 1

The value of tnOamTrCtlMaxRows specifies the maximum number of entries allowed in the tnOamTrProbeHistoryTable. The oldest entry in the tnOamTrProbeHistoryTable is removed to allow the addition of an new entry once the number of rows in the tnOamTrProbeHistoryTable reaches this value. Old entries are not removed when a new test is started. Entries are added to the tnOamTrProbeHistoryTable until tnOamTrCtlMaxRows is reached before entries begin to be removed. A value of 0 for this object disables creation of tnOamTrProbeHistoryTable entries. This object was obsoleted in release 6.0R17.

The value of tnOamTrCtlTrapGeneration specifies when and if to generate a notification for this entry: pathChange(0) - Generate a tnOamTrPathChange notification when the current path varies from a previously determined path. testFailure(1) - Generate a tnOamTrTestFailed notification when the full path to a target can't be determined. testCompletion(2) - Generate a tnOamTrTestCompleted notification when the test is completed. Bits: 'testCompletion': 2, 'testFailure': 1, 'pathChange': 0.

The value of tnOamTrCtlCreateHopsEntries specifies whether or not the current path for an Nokia SROS OAM Trace Route test is kept in the tnOamTrHopsTable on a per hop basis. tnOamTrHopsTable provides a current path topology based on the results of the OAM Trace Route tests. If this feature is not supported tnOamTrCtlCreateHopsEntries will always be set to false(2) and any attempt to change its value to true(1) will be denied.

The value of tnOamTrCtlSAA specifies if this test is an SAA test (Service Assurance Agent; 'true'), or an OAM test ('false'). If there is a tnOamSaaCtlTable row with the specified index values, 'true' is returned. Otherwise, 'false' is returned.

The value of tnOamTrCtlRuns indicates the number of times this OAM trace route test has been executed.

The value of tnOamTrCtlFailures indicates the number of times this OAM trace route test has failed.

The value of tnOamTrCtlLastRunResult indicates the completion status the last time this test was executed. If this OAM test is currently in progress, this object indicates the result of the previous test run, if any.

The value of tnOamTrCtlLastChanged indicates the time the value of a settable object in this row was last changed.

The value of tnOamTrCtlVRtrID specifies the virtual router to be used for the test. The value specified must be the index of an active row in TIMETRA-VRTR-MIB::vRtrConfTable. This object is applicable if tnOamTrCtlTestMode is 'icmpTraceRoute'. When directing an 'icmpTraceRoute' test to use a virtual router associated with a VPRN service, the virtual router can be specified using tnOamTrCtlVRtrID (with the VPRN's virtual router number) or tnOamTrCtlServiceId (with the VPRN's service number). tnOamTrCtlServiceId is preferred, because service numbers are constant across an SROS reboot (while virtual routers may be renumbered). If non-default values are specified for both tnOamTrCtlVRtrID and tnOamTrCtlServiceId, tnOamTrCtlServiceId is used. Setting this object is optional.

The value of tnOamTrCtlTgtAddrType specifies the type of host address to be used as the destination for performing a OAM Trace Route operation. Only 'ipv4', 'ipv6' and 'dns' address types are supported. This object indicates the type of address stored in the corresponding tnOamTrCtlTgtAddress object. The 'dns' address type is valid only for 'icmpTraceRoute'.

The value of tnOamTrCtlTgtAddress specifies the IP host address to be used as the destination for performing an OAM Trace Route operation. The host address type is determined by the value of the corresponding tnOamTrCtlTgtAddrType object. This parameter is required by 'vprnTraceRoute' and 'icmpTraceRoute'. This parameter is not used by 'macTraceRoute', 'lspTraceRoute', 'mcastTraceRoute', 'vccvTraceRoute', 'p2mpLspPing', or 'ethCfmLinkTrace'.

The value of tnOamTrCtlSrcAddrType specifies the type of host address to be used as the source for performing an OAM traceroute operation.

The value of tnOamTrCtlSrcAddress specifies the IP host address to be used as the source for performing an OAM Trace Route operation. The host address type is determined by the value of the corresponding tnOamTrCtlSrcAddrType object. This is an optional parameter. This object is valid only when the tnOamTrCtlTestMode has a value of 'icmpTraceRoute' or 'lspTraceRoute'.

The value of tnOamTrCtlWaitMilliSec specifies the time in milliseconds to wait for a response before sending the next probe. This object is valid only for 'icmpTraceRoute' tests.

Defines the Nokia SROS OAM Trace Route Test Results Table for keeping track of the status of a tnOamTrCtlEntry. An entry is added to the tnOamTrResultsTable when an tnOamTrCtlEntry is started by successful transition of its tnOamTrCtlAdminStatus object to enabled(1). An entry is removed from the tnOamTrResultsTable when its corresponding tnOamTrCtlEntry is deleted.

Defines an entry in the tnOamTrResultsTable. The first two indexes of the tnOamTrResultsTable are the same as the tnOamTrCtlTable in order for a tnOamTrResultsEntry to correspond to the tnOamTrCtlEntry that caused it to be created. The third index allows a history of test runs to be stored.

Reflects the operational state of a tnOamTrCtlEntry: enabled(1) - Test is active. disabled(2) - Test has stopped. Enumeration: 'disabled': 2, 'enabled': 1.

Reflects the current TTL value (range from 0 to 255) for an Nokia SROS OAM Trace Route operation. Maximum TTL value is determined by tnOamTrCtlMaxTtl. Zero is returned only in the case of an aborted 'ethCfmLinkTrace' test.

Reflects the current probe count (1..10) for an Nokia SROS OAM Trace Route operation. The maximum probe count is determined by tnOamTrCtlProbesPerHop.

This objects reports the IP address associated with a tnOamTrCtlTargetIpAddress value when the destination address is specified as a DNS name. The value of this object should be a zero length octet string when a DNS name is not specified or when a specified DNS name fails to resolve. This object was obsoleted in release 4.0 and replaced with InetAddress objects tnOamTrResultsTgtAddrType and tnOamTrResultsTgtAddress.

The current number of attempts to determine a path to a target. The value of this object MUST be started at 0. This object was made obsolete in the 3.0 release. Originally this table was used to report a summary of the results of all traceroute test for the configured test. An additional index, tnOamTrResultsTestRunIndex, has been added to this table and a row in this table now represents the results of a single traceroute test run. The new object tnOamTrCtlRuns in the tnOamTrCtlTable indicates the number of times this traceroute test has been run.

The current number of attempts to determine a path to a target that have succeeded. The value of this object MUST be reported as 0 when no attempts have succeeded. This object was made obsolete in the 3.0 release. Originally this table was used to report a summary of the results of all traceroute test for the configured test. An additional index, tnOamTrResultsTestRunIndex, has been added to this table and a row in this table now represents the results of a single traceroute test run. The new object tnOamTrCtlFailures in the tnOamTrCtlTable indicates the number of times an attempt to run this traceroute test has failed. The number of successful runs can be calclated as (tnOamTrCtlRuns - tnOamTrCtlFailures).

The date and time when the last complete path was determined.

The value of tnOamTrResultsTestRunIndex identifies the row entry that reports results for a single OAM trace route test run. The agent starts assigning tnOamTrResultsTestRunIndex values at 1 and wraps after exceeding the maximum possible value as defined by the limit of this object.

The value of tnOamTrResultsTgtAddrType indicates the Internet address type stored in tnOamTrResultsTgtAddress.

The value of tnOamTrResultsTgtAddress indicates the Internet address associated with a tnOamTrCtlTgtAddress value when the destination address is specified as a DNS name. The value of this object should be a zero length octet string when a DNS name is not specified or when a specified DNS name fails to resolve.

The object contains the overall state of the trace test.

tnOamTrProbeHistoryTable contains per-probe results for trace route tests. The number of rows in this table for a test is limited to the results of 3 runs. This table is not used for tests which have tnOamTrCtlTestMode set to 'ldpTreeTrace'.

A tnOamTrProbeHistoryEntry is created by the system when the result of a trace route probe launch is determined. A tnOamTrProbeHistoryEntry is destroyed when the corresponding tnOamTrCtlEntry is destroyed. The first two indices identify the parent tnOamTrCtlEntry. The third index identifies a trace route test run. Each subsequent index is described in its DESCRIPTION clause, below.

The value of tnOamTrProbeHistoryIndex specifies the entries belonging to a single OAM Trace Route test instance. The tnOamTrProbeHistoryIndex values are assigned starting at 1 and wrap on exceeding the upper bound.

Indicates which hop in an Nokia SROS OAM Trace Route path that the probe's results are for. The value of this object is initially determined by the value of tnOamTrCtlInitialTtl.

Indicates the index of a probe for a particular hop in an Nokia SROS OAM Trace Route path. The number of probes per hop is determined by the value of the corresponding tnOamTrCtlProbesPerHop object.

The IP address of a hop in an Nokia SROS OAM Trace Route path. The value of tnOamTrProbeHistoryIpAddr specifies the Ipv4 address of the remote node that generated this reply to a OAM Trace Route probe. This object was obsoleted in release 4.0 and replaced with InetAddress objects tnOamTrProbeHistoryAddrType and tnOamTrProbeHistoryAddress.

The amount of time measured in microseconds from when a probe was sent to when its response was received, two-way time, or when it timed out. The value of this object is reported as 0 when it is not possible to transmit a probe.

The amount of time measured in microseconds from when a OAM probe was sent to when it was received by the replier, out-bound one-way time. The value of this object is reported as 0 when it is not possible to transmit an OAM probe or the information is not available.

The result of an Nokia SROS OAM Trace Route operation made by a remote node to a particular probe.

The last implementation method specific reply code received. The Nokia SROS OAM Trace Route is usually implemented by transmitting a series of probe packets with increasing time-to-live values. A probe packet is a UDP datagram encapsulated into an IP packet. Each hop in a path to the target (destination) host rejects the probe packets (probe's TTL too small, ICMP reply) until either the maximum TTL is exceeded or the target host is received. For icmpTraceRoute, both icmp packet type and code are included.

Timestamp for when this probe results were determined.

The value of tnOamTrProbeHistoryResponsePlane indicates the type of response plane this trace route response was received on.

The value of tnOamTrProbeHistoryAddressType indicates the type of binding address information returned in response to a test. When the test has the tnOamTrCtlTestMode value 'ethCfmLinkTrace', 'unknown' is returned. For 'macTraceRoute', three types of address are applicable - 'sapId', 'localCpu', and 'sdpId'. Address type of 'sdpId' is a special case used specifically to indicate that the probe was traversing a b-vpls node in a PBB network (but where destination MAC is not necessarily known to the b-vpls node).

The value of tnOamTrProbeHistorySapId is the name of the access port of the SAP supporting the requested IP address returned in response to a 'vprnTraceRoute' probe. If the value of tnOamTrProbeHistoryAddressType is not 'sapId', this object is not relevant and MUST have a null string ''.

The value of tnOamTrProbeHistoryVersion indicates the protocol version for this OAM ping reply.

The value tnOamTrProbeHistoryRouterID indicates the downstream router ID of the node that provided this ping reply. This object is valid only when tnOamTrCtlTestMode has a value of 'lspTraceRoute'.

The value of tnOamTrProbeHistoryIfIndex indicates for a 'lspTraceRoute' or 'vccvTraceRoute' probe the ifIndex value of the interface that this probe was transmitted from. For other types of probes, this value is not significant and zero is returned.

The value of tnOamTrProbeHistoryDataLen indicates the UDP data length of the echo reply. A valid value is returned when the test has a tnOamTrCtlTestMode value of 'icmpTraceRoute', 'lspTraceRoute', 'p2mpLspTrace', or 'vccvTraceRoute'. Otherwise, this value is not significant and zero is returned.

The value of tnOamTrProbeHistorySize indicates the size in octets of the user payload in the probe request packet. It does not include the service encapsulation.

The amount of time measured in microseconds from when a OAM probe reply was sent to when it was received, in-bound one-way time. The value of this object is reported as 0 when the information is not available.

The value of tnOamTrProbeHistoryAddrType indicates the Internet address type stored in tnOamTrProbeHistoryAddress.

The value of tnOamTrProbeHistoryAddress indicates the Internet address of a hop in an Nokia SROS OAM Trace Route path.

The value of tnOamTrProbeHistorySrcGlobalId indicates the source MPLS-TP global identifier of the replying node. The value is copied from the reply's RFC 6426 Source Identifier TLV. If the TLV is absent, zero is returned. This value is relevant when tnOamTrCtlTestMode is 'lspTraceRoute' or 'vccvTraceRoute'. Otherwise, zero is returned.

The value of tnOamTrProbeHistorySrcNodeId indicates the source MPLS-TP node identifier of the replying node. The value is copied from the reply's RFC 6426 Source Identifier TLV. If the TLV is absent, zero is returned. This value is relevant when tnOamTrCtlTestMode is 'lspTraceRoute' or 'vccvTraceRoute'. Otherwise, zero is returned.

Defines the Nokia SROS OAM LSP Trace Route Control Table for providing, via SNMP, the capability of performing Nokia SROS OAM 'lspTraceRoute' test operations. The results of these tests are stored in the tnOamTrResultsTable and the tnOamTrProbeHistoryTable.

Defines an entry in the tnOamLspTrCtlTable. The first index element, tnOamTrCtlOwnerIndex, is of type SnmpAdminString, a textual convention that allows for use of the SNMPv3 View-Based Access Control Model (RFC 2575 [11], VACM) and allows a management application to identify its entries. The second index, tnOamTrCtlTestIndex, enables the same management application to have multiple outstanding requests.

The unique value which identifies this virtual router in the Nokia SROS system. The vRtrID value for each virtual router must remain constant at least from one re-initialization of the system management processor (CPM) to the next. There will always be at least one router entry defined by the agent with vRtrID=1 which represents the base transport router. This object was obsoleted in release 6.0R15 and replaced with tnOamTrCtlVRtrID in tnOamTrCtlTable.

Administrative name of the target Labeled Switch Path (LSP) for this OAM LSP Trace Route test. The LSP name must be unique within the virtual router instance specified by tnOamLspTrCtlVRtrID. This parameter is mutually exclusive with the IP prefix parameter associated with an LDP based LSP (tnOamLspTrCtlLdpIpPrefix). Either the LSP name or the LDP IP Prefix must be specified but not both.

Administrative name of the Path (LSP) for this OAM LSP Trace Route test. The Path name must be unique within the virtual router instance specified by tnOamLspTrCtlVRtrID. This is an optional parameter which can be specified only if the LSP Name parameter is specified.

The IP prefix for the LDP based LSP for this OAM LSP Trace Route test. This parameter is mutually exclusive with the LSP name parameter (tnOamLspTrCtlLspName).

This object was obsoleted in release 4.0 and replaced with InetAddress objects tnOamLspTrCtlLdpPrefixType and tnOamLspTrCtlLdpPrefix.

The IP prefix length for the LDP based LSP for this OAM LSP Trace Route test. The value of this parameter is valid only when LDP IP Prefix has been specified. This object was obsoleted in release 4.0 and replaced with InetAddress object tnOamLspTrCtlLdpPrefixLen.

The value of tnOamLspTrCtlLdpPrefixType specifies the type of Internet address stored in tnOamLspTrCtlLdpPrefix.

The value of tnOamLspTrCtlLdpPrefix specifies the Internet address prefix for the LDP based LSP for this OAM LSP Trace Route test. This parameter is mutually exclusive with the LSP name parameter (tnOamLspTrCtlLspName). Either the LDP IP Prefix or the LSP name must be specified but not both.

The value of tnOamLspTrCtlLdpPrefixLen specifies the Internet address prefix length for the LDP based LSP for this OAM LSP Trace Route test. The value of this parameter is valid only when LDP IP Prefix has been specified.

The value of tnOamLspTrCtlDownstreamMapTlv specifies the type of downstream mapping TLV to insert in the MPLS echo request PDU when launching the test. When an LSP trace route test is created, the value of this object defaults to the value of the global configuration object tnOamMplsEchoDownstreamMapTlv. The supported object combinations for LSP trace route tests are listed in the tnOamLspTrCtlTable DESCRIPTION clause.

The value of tnOamLspTrCtlTestSubMode specifies the type of LSP trace route test to perform. When this object is 'unspecified(1)', the type of LSP trace route test to be performed is determined when the test is started, from the set of tnOamLspTrCtlTable objects configured with non-default values. If there is a mismatch between tnOamLspTrCtlTestSubMode and the type of the LSP to be tested, the test will fail. For example, if tnOamLspTrCtlTestSubMode is 'static(2)', and tnOamLspTrCtlLspName refers to an LSP with TIMETRA-MPLS-MIB::vRtrMplsLspType not equal to 'mplsTp(7)', the test will fail. The supported object combinations for LSP trace route tests are listed in the tnOamLspTrCtlTable DESCRIPTION clause.

If tnOamLspTrCtlForce is 'true(1)', the test will proceed and request PDU(s) will be sent regardless of the local operational status of the tested LSP path. If tnOamLspTrCtlForce is 'false(2)', the test will fail immediately when the local operational status of the tested LSP path is down. The supported object combinations for LSP trace route tests are listed in the tnOamLspTrCtlTable DESCRIPTION clause.

Defines a table for storing the results of an OAM 'lspTraceRoute' probe operation when a Downstream Mapping TLV was returned. Each row represents a single label map within the returned downstream mapping TLV. An entry in this table is created when the result of an OAM 'lspTraceRoute' or 'p2mpLspTrace' probe is determined. An entry is removed from this table when its corresponding tnOamTrCtlEntry is deleted.

Defines an entry in the tnOamLspTrMapTable. The first two index elements identify the tnOamTrCtlEntry that a tnOamLspTrMapEntry belongs to. The third index element identifies an OAM trace route test run. The fourth index element selects the group of responses associated with a specific probe attempt. The fifth and sixth indexes select the hop and the probe at that hop for a particular Nokia SROS OAM Trace Route operation. The seventh index selects a single downstream L2 map entry within the specific probe reply.

An entry in this table is created when the result of a OAM 'lspTraceRoute' probe is determined. The initial 2 instance identifier index values identify the tnOamTrCtlEntry that a OAM probe result (tnOamTrProbeHistoryEntry) belongs to. The tnOamTrProbeHistoryIndex identifies a group of replies received in response to a specific probe transmission. The fourth and fifth indexes select the hop and the probe at that hop for a particular Nokia SROS OAM Trace Route operation. The tnOamLspTrMapIndex selects a single L2 mapping entry within a specific 'lspTraceRoute' probe reply. The agent starts assigning tnOamLspTrMapIndex values at 1.

The value of tnOamLspTrMapDSIPv4Addr indicates the IPv4 address of the downstream LSR that this entry in the tnOamLspTrMapTable describes. If the interface to the downstream LSR is numbered, then the tnOamLspTrMapDSIPv4Addr can either be the downstream LSR's Router ID or the interface address of the downstream LSR. If the interface to the downstream LSR is unnumbered, the value of tnOamLspTrMapDSIPv4Addr indicates the downstream LSR's Router ID.

The value of tnOamLspTrMapAddrType indicates the type of downstream interface address specified by tnOamLspTrMapDSIfAddr. The only valid values for tnOamLspTrMapAddrType are 'ipv4Address', 'ipv4Unnumbered', 'ipv6Address' and 'ipv6Unnumbered'.

When tnOamLspTrMapAddrType has a value of 'ipv4Address' tnOamLspTrMapDSIfAddr indicates the downstream LSR's interface address. When tnOamLspTrMapAddrType has a value of 'unnumbered', tnOamLspTrMapDSIfAddr indicates the index assigned by the upstream LSR to the interface.

The value of tnOamLspTrMapMTU indicates the largest MPLS frame (including the label stack) that fits on the interface to the downstream LSR.

Defines an entry in the tnOamVccvTrCtlTable. The first index element, tnOamTrCtlOwnerIndex, is of type SnmpAdminString, a textual convention that allows for use of the SNMPv3 View-Based Access Control Model (RFC 2575 [11], VACM) and allows a management application to identify its entries. The second index, tnOamTrCtlTestIndex, enables the same management application to have multiple outstanding requests.

The value of tnOamVccvTrCtlSdpIdVcId specifies the SDP binding of the FEC 128 pseudowire to be used when performing a vccv-trace operation. A non-zero value is mandatory when testing a FEC 128 pseudowire. The all-zeros value indicates an unused SDP binding. If tnOamVccvTrCtlSdpIdVcId is set to a non-default value, then the following objects must be default: tnOamVccvTrCtlSpokeSdpId, tnOamVccvTrCtlSaiiGlobalId, tnOamVccvTrCtlSaiiPrefix, tnOamVccvTrCtlSaiiAcId, tnOamVccvTrCtlTaiiGlobalId, tnOamVccvTrCtlTaiiPrefix, and tnOamVccvTrCtlTaiiAcId. If the value of tnOamVccvTrCtlSdpIdVcId is non-zero and invalid, or the pseudowire is administratively down, or unavailable, the OAM Trace request message probe is not sent and an appropriate error value is written to tnOamTrProbeHistoryStatus for that probe entry.

Defines an entry in the tnOamSaaCtlTable. The first index element, tnOamSaaCtlOwnerIndex, is of type SnmpAdminString, a textual convention that allows for use of the SNMPv3 View-Based Access Control Model (RFC 2575 [11], VACM) and allows a management application to identify its entries. The second index, tnOamSaaCtlTestIndex, enables the same management application to have multiple outstanding requests.

The test name index of the Nokia SROS OAM Service Assurance Agent, SAA, test. This is locally unique, within the scope of an tnOamSaaCtlOwnerIndex.

This object allows entries to be created and deleted in the tnOamSaaCtlTable. Deletion of an entry in this table results in all corresponding control and results entries in either the ping or traceroute tables. Activation of a Nokia SROS OAM ping or trace route operation is controlled via tnOamPingCtlAdminStatus or tnOamTrCtlAdminStatus and not by changing this object's value to 'active (1)'. An attempt to delete an entry in this table by setting this object's value to 'destroy (6)' will fail with an inconsistentValue error if the associated ping or traceroute test is in progress. An attempt to delete an entry in this table by setting this object's value to 'destroy (6)' will fail with an inconsistentValue error if the value of tnOamSaaCtlAdminStatus is not 'outOfService'. The operational state of an Nokia SROS OAM SAA test operation can be determined by examination of its associated tnOamPingResultsOperStatus or tnOamTrResultsOperStatus object.

The value of tnOamSaaCtlLastChanged indicates the time the value of a settable object in this row was last changed.

The value of tnOamSaaCtlAdminStatus indicates the desired administrative state of the Service Assurance Agent, SAA, test. When the value of tnOamSaaCtlAdminStatus is 'outOfService', an attempt to start this SAA test by setting its associated tnOamPingCtlAdminStatus or tnOamTrCtlAdminStatus to 'enabled (1)' will fail with an inconsistentValue error. When the value of tnOamSaaCtlAdminStatus is 'inService' attempts to modify any other object in the associated tnOamPingCtlTable, tnOamTrCtlTable or the control table for the specific OAM test type will fail with an inconsistentValue error.

The value of tnOamSaaCtlDescr specifies a user provided description string for this SAA test. It can consist of any printable, seven-bit ASCII characters up to 80 characters in length.

The value of tnOamSaaCtlTestMode indicates the type of Service Assurance Agent, SAA, test to be performed. When the value of this object is 'notConfigured', no associated entry exists in either the tnOamPingCtlTable or tnOamTrCtlTable. When the value of this object is 'ping', an associated test entry is configured in the tnOamPingCtlTable. When the value of this object is 'traceroute', an associated test entry is configured in the tnOamTrCtlTable.

The value of tnOamSaaCtlAcctPolicyId specifies the accounting policy used to record the information obtained from the results tables. A value of zero (0) specifies no accounting policy.

The value of tnOamSaaCtlSuppressAccounting specifies whether or not the updating of accounting files is suppressed. The value of 'true (1)' is applicable only when an accounting policy has been specified by tnOamSaaCtlAcctPolicyId. Upon completion of a test, this object is reset to its default value.

The value of tnOamSaaCtlContinuous specifies whether or not the OAM SAA test is to be executed indefinitely.

The value of tnOamSaaCtlKeepProbeHistoryAdm specifies whether or not per-probe history table rows will be created for this test. A test without per-probe history table rows consumes less CPM RAM. tnOamSaaCtlKeepProbeHistoryOpr is a read-only operational value derived from tnOamSaaCtlKeepProbeHistoryAdm. The bulk of the tnOamSaaCtlKeepProbeHistoryAdm semantics are described in the tnOamSaaCtlKeepProbeHistoryOpr DESCRIPTION clause. An attempt to set tnOamSaaCtlKeepProbeHistoryAdm to 'drop(2)' when tnOamSaaCtlTestMode is not 'ping(1)' returns an 'inconsistentValue' error to the manager. When the SAA test's test mode is deconfigured (i.e. tnOamSaaCtlTestMode becomes 'notConfigured(0)'), tnOamSaaCtlKeepProbeHistoryAdm returns to its default value. Enumeration: 'auto': 3, 'drop': 2, 'keep': 1.

The value of tnOamSaaCtlKeepProbeHistoryOpr indicates whether or not per-probe history table rows will be created for this test. A test without per-probe history table rows consumes less CPM RAM. The value of tnOamSaaCtlKeepProbeHistoryOpr is derived from the value of`tnOamSaaCtlKeepProbeHistoryAdm, as shown in the following table. tnOamSaaCtlKeepProbeHistoryAdm tnOamSaaCtlKeepProbeHistoryOpr -------------------------------- -------------------------------------- 'keep(1)' 'keep(1)' 'drop(2)' 'drop(2)' 'auto(3)' 'keep(1)' or 'drop(2)', chosen by SROS The history table rows created for the combinations of tnOamSaaCtlKeepProbeHistoryOpr and tnOamSaaCtlTestMode values are shown in the following table. Configuration Options History Table Rows Created -------------------------- -------------------------- 'keep(1)', 'ping(1)' tnOamPingHistoryTable or tnOamMacPingHistoryTable 'keep(1)', 'traceroute(2)' tnOamTrProbeHistoryTable 'drop(2)', 'ping(1)' none 'drop(2)', 'traceroute(2)' unsupported combination. If tnOamSaaCtlTestMode is 'notConfigured(0)', the value of tnOamSaaCtlKeepProbeHistoryOpr is insignificant, since a test without a test mode cannot be started. When a Get is performed on tnOamSaaCtlKeepProbeHistoryOpr in this case, 'keep(1)' is returned. If tnOamSaaCtlKeepProbeHistoryAdm is 'auto(3)': 1. tnOamSaaCtlKeepProbeHistoryOpr is 'drop(2)' if a) the test's probe count is greater than 100, OR b) the test's interval is less than one second, OR c) tnOamSaaCtlTestMode is 'ping(1)' AND the test is continuous (i.e. tnOamSaaCtlContinuous is 'true') AND an accounting policy is specified (i.e. tnOamSaaCtlAcctPolicyId is non- zero). 2. Otherwise, tnOamSaaCtlKeepProbeHistoryOpr is 'keep(1)'. Enumeration: 'drop': 2, 'keep': 1.
