The value of tmnxPtpClockAdminState specifies whether PTP 1588 is enabled on the system or not.

The value of tmnxPtpClockClockType specifies the clock behavior of PTP1588 on the system. This object can only be modified if tmnxPtpClockAdminState is set to 'outOfService (3)', otherwise an 'inconsistentValue' error is returned.

The value of tmnxPtpClockProfile specifies the conformance of the PTP system to either the default IEEE 1588-2008 behavior, or the ITU-T profile. Modification of this object indirectly resets the value of tmnxPtpClockDomain to the corresponding default value for the specified profile. This object can only be modified if tmnxPtpClockAdminState is set to 'outOfService (3)', otherwise an 'inconsistentValue' error is returned.

The value of tmnxPtpClockDomain specifies the domain in which PTP 1588 runs on the system. This object can only be modified if tmnxPtpClockAdminState is set to 'outOfService (3)', otherwise an 'inconsistentValue' error is returned.

The value of tmnxPtpClockAnnounceInterval specifies the packet rate requested in REQUEST_UNICAST_TRANSMISSION signaling messages for announce packets. This object can only be modified if tmnxPtpClockAdminState is set to 'outOfService (3)', otherwise an 'inconsistentValue' error is returned.

The value zero (0), specifies no wait time. This object can only be modified if tmnxPtpClockAdminState is set to 'outOfService (3)', otherwise an 'inconsistentValue' error is returned.

The value of tmnxPtpClockNetworkType specifies whether the SROS is configured to use PTP clock classes corresponding to SONET or SDH quality levels. Enumeration: 'sonet': 1, 'sdh': 2.

The tmnxPtpPeerConfigTable consists of peer configuration information.

The tmnxPtpPeerConfigEntry contains information pertaining to an individual PTP 1588 peer. Individual PTP peers are identified by the IP address of the peer PTP clock. If tmnxPtpClockClockType is 'ordinarySlave (1)', entries may be created and deleted via SNMP set operations using tmnxPtpPeerRowStatus. The tmnxPtpPeerRemoteMaster attribute will be created with a value of 'true', and the tmnxPtpPeerRemoteSlave attribute will be created with a value of 'false'. Neither or these attributes may be subsequently changed. These entries correspond to PTP grandmaster or boundary clocks providing timing information to the local clock. In order to delete an entry, tmnxPtpPeerAdminState must first be set to 'outOfService (3)'. If tmnxPtpClockClockType is 'ordinaryMaster (2)', entries are automatically created upon receipt of PTP signaling packets requesting unicast transmission of PTP packets. Entries cannot be created or deleted via SNMP set operations. These entries correspond to PTP slave boundary clocks receiving timing information from the local clock. These entries are created by the system with tmnxPtpPeerRemoteMaster set to 'false' and tmnxPtpPeerRemoteSlave set to 'true'. If tmnxPtpClockClockType is 'boundary (3)', entries corresponding to grandmaster or boundary PTP clocks providing timing to the local clock may be created and deleted via SNMP set operations, in the same manner as when tmnxPtpClockClockType is 'ordinarySlave (1)'. As well, entries corresponding to slave or boundary PTP clocks receiving timing from the local clock may be automatically created by the system, in the same manner as when tmnxPtpClockClockType is 'ordinaryMaster (2)'. For an individual entry, the value of tmnxPtpPeerRemoteMaster along with tmnxPtpPeerRemoteSlave indicates the direction of flow of timing information between the local PTP clock and the peer PTP clock. There are three cases: 1) If tmnxPtpPeerRemoteMaster is 'true', and tmnxPtpPeerRemoteSlave is 'false', the peer PTP clock is providing timing to the local PTP clock. In this case, PTP Announce, Sync, and Delay Reponse packets are sent from the peer PTP clock to the local PTP clock, and PTP Delay Request packets are sent from the local PTP clock to the peer PTP clock. This type of PTP peer may exist when tmnxPtpClockClockType is either 'ordinarySlave (1)' or boundary (3)'. 2) If tmnxPtpPeerRemoteMaster is 'false', and tmnxPtpPeerRemoteSlave is 'true', the local PTP clock is providing timing to the peer PTP clock. In this case, PTP Announce, Sync, and Delay Reponse packets are sent from the local PTP clock to the peer PTP clock, and PTP Delay Request packets are sent from the peer PTP clock to the local PTP clock. This type of PTP peer may exist when tmnxPtpClockClockType is either 'ordinaryMaster (2)' or boundary (3)'. 3) If tmnxPtpPeerRemoteMaster and tmnxPtpPeerRemoteSlave are both set to 'true', the local clock and remote PTP clock have a peer relationship. Timing information may flow in either direction, depending on the decision of the PTP Best Master Clock Algorithm running on each PTP clock. This type of PTP peer may only exist when tmnxPtpClockClockType is 'boundary (3)'. When tmnxPtpClockClockType is 'boundary (3)', a peer entry may be changed from one that is only receiving timing from the local clock, to one that may either receive or provide timing, by setting tmnxPtpPeerRemoteMaster to 'true'.

The value of tmnxPtpPeerIpAddrType specifies the type of address of the PTP 1588 peer. This object represents the first index in the table.

The value of tmnxPtpPeerIpAddress specifies the address of the PTP 1588 peer. This object represents the second index in the table.

The value of tmnxPtpPeerRowStatus specifies the row status of the PTP 1588 peer. This object controls the creation and deletion of peer PTP grandmaster and boundary clocks that may provide timing to the local PTP clock. These PTP peers may only be created when tmnxPtpClockClockType is set to 'ordinarySlave (1)' or 'boundary (3)'. For these peers, tmnxPtpPeerRemoteMaster will be set to 'true'. Before deleting one of these PTP peers, tmnxPtpPeerAdminState must be set to 'outOfService (3)'. Peers that correspond to slave or boundary PTP clocks that may receive timing information from the local clock can not be created or deleted by the use of this object. Instead, they are dynamically created by the system through the operation of the Precision Time Protocol.

The value of tmnxPtpPeerLastChanged indicates the time, since system startup, that the PTP 1588 peer was created or modified.

The value of tmnxPtpPeerAdminState specifies the administrative state of the PTP 1588 peer, that is, whether or not the peer will be used by the Precision Time Protocol (PTP).

The value of tmnxPtpPeerPortState indicates the current state of the PTP port used when communicating with the remote peer. If tmnxPtpClockClockType is either 'ordinarySlave (1)' or 'ordinaryMaster (2)', the value of tmnxPtpPeerPortState is the same as tmnxPtpClockPortState. The value of this object corresponds to the portDS.portState data set member defined in IEEE Std 1588-2008.

The value of tmnxPtpPeerLocalPriority specifies the local priority used to choose between PTP masters in the Best Master Clock Algorithm (BMCA). This object is only relevant when tmnxPtpClockProfile is set to 'g8265dot1-2010 (1)'. The parameter is ignored otherwise.

The value of tmnxPtpPeerRemoteMaster indicates whether or not the peer is configured as a remote grandmaster or boundary clock that may provide timing information to the local clock. If tmnxPtpClockClockType is 'ordinarySlave (1)', all entries in this table will have tmnxPtpPeerRemoteMaster set to 'true', and it cannot be changed. If tmnxPtpClockClockType is 'ordinaryMaster (2)', all entries in this table will have tmnxPtpPeerRemoteMaster set to 'false', and it cannot be changed. If tmnxPtpClockClockType is 'boundary (3)', there may be entries in this table with tmnxPtpPeerRemoteMaster set to 'false', indicating that the local clock is only providing timing information to the remote PTP peer. This peer may be changed to one that may either receive or provide timing, by setting tmnxPtpPeerRemoteMaster to 'true'. When the value of this object is 'true', a corresponding row in the tmnxPtpPeerMasterStatusTable will exist for this peer.

The value of tmnxPtpPeerRemoteSlave specifies whether or not the peer is acting as a remote slave or boundary clock that may be receiving timing information from the local clock. Remote slave clocks are learned by the local clock upon reception of PTP signaling packets, and cannot be configured via SNMP set operations. If tmnxPtpPeerRemoteSlave is 'true', it indicates that the local PTP clock may provide timing information to the PTP peer. If tmnxPtpClockClockType is 'ordinarySlave (1)', all entries in this table will have tmnxPtpPeerRemoteSlave set to 'false'. If tmnxPtpClockClockType is 'ordinaryMaster (2)', all entries in this table will have tmnxPtpPeerRemoteSlave set to 'true'.

The value of tmnxPtpPeerClockId indicates the clock identity of the peer.

The value of tmnxPtpPeerLocalPortNumber indicates the PTP port number assigned by the local clock and used when communicating with the remote clock.

The value of this object corresponds to the portDS.portIdentity.portNumber data set member defined in IEEE Std 1588-2008.

The value of tmnxPtpPeerRemotePortNumber indicates the PTP port number used by the remote peer when communicating with the local clock.

The value of tmnxPtpPeerTxTimeStampPoint indicates the reference point used to generate the PTP timestamp for the last transmitted PTP event packet. If no event packets have been transmitted, the value is 'unknown(0)'. If PTP event packets are transmitted out an interface with tmnxPtpVRtrIfAdminState set to 'inService(2)', the value is 'port(1)'. If PTP event packets are transmitted out an interface with tmnxPtpVRtrIfAdminState set to 'outOfService(3)', the value is 'cpm(2)'.

The value of tmnxPtpPeerLastTxPortId along with tmnxPtpPeerLastTxPortEncapType and tmnxPtpPeerLastTxPortEncapValue indicates the last port used to transmit PTP packets to the PTP peer. If no packets have been transmitted, tmnxPtpPeerLastTxPortId contains the 'invalid portid' value of 0x1e000000.

The value of tmnxPtpPeerLastTxPortEncapType along with tmnxPtpPeerLastTxPortId and tmnxPtpPeerLastTxPortEncapValue indicates the last port used to transmit PTP packets to the PTP peer.

The value of tmnxPtpPeerRxTimeStampPoint indicates the reference point used to generate the PTP timestamp for the last received PTP event packet. If no event packets have been received, the value is 'unknown(0)'. If PTP event packets are received on an interface with tmnxPtpVRtrIfAdminState set to 'inService(2)', and the destination IP address of the received packet is either the local IPv4 address of the interface or the PTP system IPv4 address, the value is 'port(1)'. Otherwise, the value is 'cpm(2)'.

The value of tmnxPtpPeerLastRxPortId along with tmnxPtpPeerLastRxPortEncapType and tmnxPtpPeerLastRxPortEncapValue indicates the last port used to receive PTP packets from the PTP peer. If no packets have been received, tmnxPtpPeerLastRxPortId contains the 'invalid portid' value of 0x1e000000.

The value of tmnxPtpPeerLastRxPortEncapType along with tmnxPtpPeerLastRxPortId and tmnxPtpPeerLastRxPortEncapValue indicates the last port used to receive PTP packets from the PTP peer.

The tmnxPtpVRtrIfTable table contains PTP configuration pertaining to IP interfaces.

Each row entry represents the PTP configuration corresponding to an interface configured in a virtual router. Entries are created and deleted when entries in the vRtrIfTable are created and deleted.

The value of tmnxPtpVRtrIfAdminState specifies the administrative state of the PTP hardware assist configuration of the interface. If the value is 'inService(2)', the timestamp point for PTP event packets is configured to be the physical layer. This corresponds to timestamp point 'A' in IEEE 1588-2008, Figure 14. If the value is 'outOfService(3)', the timestamp point for PTP event packets is configured to be the operating system kernel. This corresponds to timestamp point 'B' in IEEE 1588-2008, Figure 14. The value may only be configured to 'inService(2)' if all of the following are true: 1. An IPv4 address is configured against the interface. 2. An Ethernet physical port (or VLAN tag on an Ethernet physical port) has been associated with the interface. 3. The Ethernet port associated with the interface must not be configured for WAN mode. In other words, the tmnxPortEtherXGigMode attribute for the port must be either 'notApplicable' or 'lan'. 4. The MDA associated with the interface has synchronous Ethernet enabled. In other words, the tmnxMDASynchronousEthernet attribute for the MDA must be 'enabled'. 5. The port associated with the interface is on an IOM that supports the hardware assist configuration. 6. The port associated with the interface supports the hardware assist configuration. 7. The firmware currently in use by the active CPM support the hardware assist configuration. 8. The firmware currently in use by the IOM card supports the hardware assist configuration. After an upgrade from an older release, the IOM may continue using older firmware. A hard reset of the IOM is then needed to bring the IOM firmware up to date. 9. The firmware currently in use by the MDA supports the hardware assist configuration. After an upgrade from an older release, the MDA may continue using older firmware. A hard reset of the MDA or IOM is then needed to bring the MDA firmware up to date. If the physical port bound to the interface is removed, tmnxPtpVRtrIfAdminState is set to 'outOfService(3)'. If the IPv4 address assigned to the interface is removed, tmnxPtpVRtrIfAdminState is set to 'outOfService(3)'.

The value of tmnxPtpNotifyRowPointer indicates a row in a table that has triggered a notification.

The value of tmnxPtpNotifyRowDescription indicates the description explaining the cause of the notification.

The tmnxPtpCardNotSupported notification is generated when the Precision Timing Protocol (PTP) is enabled on a card that is not capable of clock recovery using PTP. This notification is triggered when the TIMETRA-CHASSIS-MIB::tmnxCpmCardOscillatorType is not 'ocxo (3)', the tmnxPtpClockClockType is set to 'ordinarySlave (1)' or 'boundary (3)', and tmnxPtpClockAdminState is set to 'inService (2)'. [EFFECT] While this event is active, tmnxPtpClockOperState will be 'outOfService (3)' on the card that this notification was generated. [RECOVERY] This event is cleared when a replacement CPM card with an Oscillator of type 'ocxo (3)' is inserted. tmnxPtpCardNotSupportedClear is generated when this event is cleared.

The tmnxPtpCardNotSupportedClear notification is generated when the tmnxPtpCardNotSupported event is cleared for a particular CPM card.

The tmnxPtpMasterClockChangedEvent is generated when the Master/Parent Clock for the Precision Timing Protocol (PTP) changes on the system.

The tmnxPtpClockRecoveryStateChange is generated when the Precision Timing Protocol (PTP) clock recovery state changes on the system.

The tmnxPtpOutOfResources notification is generated when the Precision Timing Protocol (PTP) process on the card is out of resources. This may occur in either two situations: 1. The number of PTP peers exceeds the system limit. 2. The total unicast packet rate negotiated with all PTP peers has reached the maximum packet rate supported by the system. Exceeding this rate would impact the ability of the master clock to provide an accurate stream of timing packets to each remote slave clock. If either of the above two situation occurs, the PTP process will reject any new unicast packet requests from remote slave PTP peers. tmnxPtpOutOfResourcesClear is generated when this event is cleared.

The tmnxPtpOutOfResourcesClear notification is generated when both the total number of active PTP peers and the total negotiated unicast packet rate goes below 90% of the system limit.

The tmnxPtpDynamicChange notification is generated when an object dynamically (i.e. not by configuration) changes state. This notification identifies the affected row.
