Tok_String

A human readable string rsysresenting the name of the user. This is the (User-based Security) Model dependent security ID.

An indication of whether messages sent on behalf of this user to/from the SNMP engine identified by usmUserEngineID, can be authenticated, and if so, the type of authentication protocol which is used. An instance of this object is created concurrently with the creation of any other object instance for the same user (i.e., as part of the processing of the set operation which creates the first object instance in the same concsystual row). If an initial set operation (i.e. at row creation time) tries to set a value for an unknown or unsupported protocol, then a wrongValue error must be returned. The value will be overwritten/set when a set operation is performed on the corresponding instance of UserCloneFrom. Once instantiated, the value of such an instance of this object can only be changed via a set operation to the value of the NoAuthProtocol. If a set operation tries to change the value of an existing instance of this object to any value other than NoAuthProtocol, then an inconsistentValue error must be returned. If a set operation tries to set the value to the NoAuthProtocol while the UserPrivProtocol value in the same row is not equal to NoPrivProtocol, then an inconsistentValue error must be returned. That means that an SNMP command generator application must first ensure that the UserPrivProtocol is set to the NoPrivProtocol value before it can set the UserAuthProtocol value to NoAuthProtocol.

An indication of whether messages sent on behalf of this user to/from the SNMP engine identified by usmUserEngineID, can be protected from disclosure, and if so, the type of privacy protocol which is used. An instance of this object is created concurrently with the creation of any other object instance for the same user (i.e., as part of the processing of the set operation which creates the first object instance in the same concsystual row). If an initial set operation (i.e. at row creation time) tries to set a value for an unknown or unsupported protocol, then a wrongValue error must be returned. The value will be overwritten/set when a set operation is performed on the corresponding instance of usmUserCloneFrom. Once instantiated, the value of such an instance of this object can only be changed via a set operation to the value of the NoPrivProtocol. If a set operation tries to change the value of an existing instance of this object to any value other than NoPrivProtocol, then an inconsistentValue error must be returned. Note that if any privacy protocol is used, then you must also use an authentication protocol. In other words, if usmUserPrivProtocol is set to anything else than NoPrivProtocol, then the corresponding instance of usmUserAuthProtocol cannot have a value of usmNoAuthProtocol. If it does, then an inconsistentValue error must be returned.

The status of this concsystual row. Until instances of all corresponding columns are appropriately configured, the value of the corresponding instance of the usmUserStatus column is notReady. In particular, a newly created row for a user who employs authentication, cannot be made active until the corresponding usmUserCloneFrom and usmUserAuthKeyChange have been set. Further, a newly created row for a user who also employs privacy, cannot be made active until the usmUserPrivKeyChange has been set. The RowStatus TC [RFC2579] requires that this DESCRIPTION clause states under which circumstances other objects in this row can be modified: The value of this object has no effect on whether other objects in this concsystual row can be modified, excsyst for usmUserOwnAuthKeyChange and usmUserOwnPrivKeyChange. For these 2 objects, the value of usmUserStatus MUST be active.

The name of the group to which this entry (e.g., the combination of securityModel and securityName) belongs. This groupName is used as index into the vacmAccessTable to select an access control policy. However, a value in this table does not imply that an instance with the value exists in table vacmAccesTable.

In order to gain the access rights allowed by this concsystual row, this securityModel must be in use.

The minimum level of security required in order to gain the access rights allowed by this concsystual row. A securityLevel of noAuthNoPriv is less than authNoPriv which in turn is less than authPriv. If multiple entries are equally indexed excsyst for this vacmAccessSecurityLevel index, then the entry which has the highest value for vacmAccessSecurityLevel is selected.

The value of an instance of this object identifies the MIB view of the SNMP context to which this concsystual row authorizes read access. The identified MIB view is that one for which the vacmViewTreeFamilyViewName has the same value as the instance of this object; if the value is the empty string or if there is no active MIB view having this value of vacmViewTreeFamilyViewName, then no access is granted.

The value of an instance of this object identifies the MIB view of the SNMP context to which this concsystual row authorizes write access. The identified MIB view is that one for which the vacmViewTreeFamilyViewName has the same value as the instance of this object; if the value is the empty string or if there is no active MIB view having this value of vacmViewTreeFamilyViewName, then no access is granted.

The value of an instance of this object identifies the MIB view of the SNMP context to which this concsystual row authorizes access for notifications. The identified MIB view is that one for which the vacmViewTreeFamilyViewName has the same value as the instance of this object; if the value is the empty string or if there is no active MIB view having this value of vacmViewTreeFamilyViewName, then no access is granted.

The status of this concsystual row. The RowStatus TC [RFC2579] requires that this DESCRIPTION clause states under which circumstances other objects in this row can be modified: The value of this object has no effect on whether other objects in this concsystual row can be modified.

Tok_String

Tok_String

The human readable name for a family of view subtrees.

The MIB subtree which when combined with the corresponding instance of vacmViewTreeFamilyMask defines a family of view subtrees.

The bit mask which, in combination with the corresponding instance of vacmViewTreeFamilySubtree, defines a family of view subtrees. Each bit of this bit mask corresponds to a sub-identifier of vacmViewTreeFamilySubtree, with the most significant bit of the i-th octet of this octet string value (extended if necessary, see below) corresponding to the (8*i - 7)-th sub-identifier, and the least significant bit of the i-th octet of this octet string corresponding to the (8*i)-th sub-identifier, where i is in the range 1 through 16. Each bit of this bit mask specifies whether or not the corresponding sub-identifiers must match when determining if an OBJECT IDENTIFIER is in this family of view subtrees; a 1 indicates that an exact match must occur; a 0 indicates wild card, i.e., any sub-identifier value matches. Thus, the OBJECT IDENTIFIER X of an object instance is contained in a family of view subtrees if, for each sub-identifier of the value of vacmViewTreeFamilySubtree, either: the i-th bit of vacmViewTreeFamilyMask is 0, or the i-th sub-identifier of X is equal to the i-th sub-identifier of the value of vacmViewTreeFamilySubtree. If the value of this bit mask is M bits long and there are more than M sub-identifiers in the corresponding instance of vacmViewTreeFamilySubtree, then the bit mask is extended with 1s to be the required length. Note that when the value of this object is the zero-length string, this extension rule results in a mask of all-1s being used (i.e., no wild card), and the family of view subtrees is the one view subtree uniquely identified by the corresponding instance of vacmViewTreeFamilySubtree. Note that masks of length greater than zero length do not need to be supported. In this case this object is made read-only.

Indicates whether the corresponding instances of vacmViewTreeFamilySubtree and vacmViewTreeFamilyMask define a family of view subtrees which is included in or excluded from the MIB view.

The status of this concsystual row. The RowStatus TC [RFC2579] requires that this DESCRIPTION clause states under which circumstances other objects in this row can be modified: The value of this object has no effect on whether other objects in this concsystual row can be modified.

Specifies the maximum number of interfaces that can be present in the system.

Specifies the maximum number of physical interfaces that can be present in the system.

Shows an ifIndex which is available for creation of any new virtual (non-physical) interface in the system. This ifIndex value can be used for creation of interfaces in the ifMainTable or any media-specif MIB. For creation of physical interfaces, any free ifIndex between 1 and ifMaxPhysInterfaces can be used.

A list of all the interface entries in the system. This table contains objects which are applicable to all types of interfaces in the system. This table is a proprietary extension to the standard ifTable and ifXTable. The index to this table has the semantics of the MIB-2 ifIndex.

An entry containing management information applicable to a particular interface.

A unique value, greater than zero, for each interface. This object is identical to the ifIndex of the standard MIB-2 ifTable.

The type/protocol of interface. Specification of the object is mandatory for all interfaces. This value should be specified after the row creation in the ifMainTable and before setting any other object in this table. Once the type is specified, it cannot be changed - the interface should be deleted for changing the type of the interface. The ethernetCsmacd(6), iso88025TokenRing(9), aal5(49), async(84) and hdlc(118) are physical interfaces while all other types are virtual or logical interfaces. For creation of physical interface types, it is mandatory to specify the handle to the device driver using the ifAlias object of the standard ifXTable before specifying the type. This handle could be something like eth1 or /dev/abcd.

The MTU for the interface as shown to the higher interface sub-layer (this value should not include the encapsulation or header added by the interface). If IP is operating over the interface, then this value indicates the IP MTU over this interface. For changing the MTU of any interface, the interface must be brought down first - changing MTU while the interface is administratively up is not permitted. If not specified during interface creation, a default value is assigned based on the ifMainType given to the particular interface. While configuring for logical VLAN interfaces, care should be taken to, configure this value as the lowest of the MTU values of the member ports.

The desired state of the interface. This object can be set only when the ifMainRowStatus of the interface is active. This object has the semantics of the ifAdminStatus of the standard ifTable. The testing(3) state indicates that no operational packets can be passed - this state is not currently supported. When a managed system initializes, all interfaces start with ifMainAdminStatus in the down(2) state, its a default state also. As a result of either explicit management action or per configuration information retained by the managed system, ifMainAdminStatus is then changed to the up (1) state (or remains in the down(2) state).

The current operational state of the interface. The testing (3) state indicates that no operational packets can be passed - this state is not supported currently. If ifMainAdminStatus is down (2) then ifMainOperStatus would be down (2). If ifMainAdminStatus is changed to up (1) then ifMainOperStatus should change to up (1) if the interface is ready to transmit and receive work traffic; it should change to dormant (5) the interface is waiting for external actions (such as a serial line waiting for an incoming connection); it should change to lowerLayerDown(7) state if it cannot be made up as the interface sub-layer below it is down; it should remain in the down (2) state if and only if there is a fault that prevents it from going to the up (1) state; it should remain in the notPresent (6) state if the interface has missing (typically, hardware) components. The status unknown(4) is shown when it is not possible to determine the exact status of the interface - e.g. the interface sub-layer is performing negotiations - during this period the interface is not up but at the same time, it is not a fault condition and hence it cannot be shown as down - in such periods the status is shown as unknown. This object has the semantics of the ifOperStatus of the standard ifTable.

The encapsulation type to be used over the interface. For Ethernet interfaces, the default encapsulation type is ethernetV2(8). The other possible encapsulation is llcSnap(6). If other(1) is specified then an automatic encapsulation type learning method is used in ARP for determining the encapsulation for unicast destinations while the multicast and broadcast destinations use ethernetV2(8). For PPP and MLPPP interfaces, the encapsulation type can only be other(1) and this is the default value. For FR VCs, the value can be nlpid(2) (for carrying protocols which have NLPID) or nlpidSnap(3) (for other protocols). The default is nlpid(2) and the types of protocols supported are inferred from the stack-layering implemented over the interface. For X.25 VCs, the value can be nlpid(2) or nlpidSnap(3) (where the VC can carry multiplexed protocol traffic with each data packet containing the NLPID or SNAP header) or cudNlpid(4) or cudNlpidSnap(5) (where the CUD specifies the NLPID of the protocol or SNAP and the data packets do not contain these headers - for dedicated VCs). The default is cudNlpid(4). For ATM VCs, the default is llcSnap(6) but the vcMultiplexed(7) encapsulation is also supported. This object is not applicable to other interfaces.

The Bridge port type of this specified externally accessible port. Bridge Port type can be specified only for switch ports and not for router ports. providerNetworkPort - Port Connected to a single Provider. SVLAN Classification is based on only the PVID configured for the port for untagged packets. customerNetworkPortPortBased - Port in the S-VLAN component that can transmit or received frames for single customer. All packets received on this port, are mapped to one single service instance identified by the PVID of that Port. Accsystable Port Type will be always Admit only Untagged or Priority Tagged Frames on this port. customerNetworkPortStagged - Port in the S-VLAN component that can transmit or received frames for single customer. VLAN classification on this interface will be based on the S-tag received or on the PVID of the port. Ingress Filtering will be always enabled on this port. customerEdgePort - Port in a Provider Edge Bridge connected to a single customer. Multiple services can be provide on this port. The Packets received on this interface will be first classified to a CVLAN. CVLAN classification can be based on the Vid in the C-Tag present in the packet (if it C-tagged packet) or from the pvid of the port. Service instance selection (S-VLAN selection) for a frame is done based on the entry present in the C-VID registration table for the pair (C-VID, recsystion Port). CustomerEdgePort configuration is allowed only in Provider Edge Bridges. propCustomerEdgePort - Port connected to a single customer, where multiple services can be provided based on only Proprietary SVLAN classification tables. S-VLAN classification will not happen based on C-VID registration table on this port. propCustomerEdgePort configuration is allowed only in Provider Edge Bridges. propCustomerNetworkPort - Port connected to a single customer, where multiple service can be provided based on CVLANs by assigning one of the Proprietary SVLAN classification tables to this port. The services can also be assigned using other proprietary SVLAN classification tables where CVLAN is not the index of the table. propProviderNetworkPort - Port connected to a Q-in-Q Bridge located inside Provider Network. This port is part of S-VLAN component. If packets to be tagged and sent out of this port will have 0x8100 as the ether type. Similarly pakcets with standard Q tag (ether type as 0x8100) received will be considered as S-Tagged packets. customerBridgePort - Type of the port to be used in customer bridges as well in Provider(Q-in-Q) bridges. This type is not valid in Provider Core bridges as well as Provider Edge bridge. In Customer bridges and in Provider Bridges only customerPort option is allowed. Bridge Port Type cannot be set for a port-channel port, if some physical ports are aggregated in it. Also Bridge Port type cannot be set for a port, if part of a port-channel. Whenever the Bridge port type changes, the previous configuration associated with the port will be flushed. For example. whenever CNP(STagged) and PNP port types are changed to any other port type, - The unicast entries learnt on this port and - The VID translation table entries associated with the port will be flushed. Whenever CEP port type is changed to any other port type, - The unicast entries learnt on this port - The C-VID registration table entries associated with the port - The PEP configuration table entries - The service priority regeneration table entries will be flushed. Even the vlan membership of the port will be removed when the Pbport type is changed.

A RowStatus variable for addition, deletion and in-activation of the interfaces. Specification of the object is mandatory for all interfaces. When the status is active, the interface is created and ready to use in the respective protocol modules. When the status is notInService, the interface has not been registered with the respective protocol modules and as such those modules are not aware of the existence of the interface - creation is hence, incomplete. Setting an active interface to notInService results in de-registration/deletion of the interface from the respective protocol modules and all the configurations associated with that interface in those modules may be lost. Deletion of an interface, may affect the status of other interfaces which are layered above or below it in the Interface Stack (ifStackTable) and may result in other interfaces being made notReady or notInService.

A list of all the interface entries in the system which are registered with IP. This table contains objects which are applicable for the management of IP over the network interfaces in the system. This table is a extension to the ifMainTable. The index to this table has the semantics of the ifMainIndex of the ifMainTable. Entries are created automatically in this table for any interface sub-layer which is layer below IP using the ifStackTable. Similarly, entries are deleted from this table when the interfaces layering below IP is removed.

An entry containing management information applicable to a particular interface over which IP is operating.

The mechanism to be used for allocation of IP address for this interface. The value negotiation can be used only for PPP and MLPPP interfaces which support obtaining of IP addresses through negotiation. The dynamic(3) option takes an IP address dynamically from the available server (dhcp/bootp/rarp) according to the protocol specified in ifIpAddrAllocProtocol. If the method specified is manual and the IP address is not provided (then the interface would be treated as a un-numbered interface.

Specifies the IP address given to this interface. The specification of this object is mandatory for all network interfaces (Ethernet, FR VC, IPoA interface, PPP link - not under MP, MP interface and X.25 VC). If the interface is not a network interface then the default value of 0.0.0.0 is assigned and the interface is treated as a un-numbered interface by IP.

Specifies the IP Subnet Mask for this interface. The value should be specified only for network interfaces and any valid VLSM is accsysted. If not specified, this object takes the default subnet mask value based on the class of the IP address configured for the interface.

Specifies the IP broadcast address for this interface. The value should be specified only for network interfaces and any valid broadcast address based on a valid VLSM is accsysted. If not specified, this object takes the default value based on the class of the IP address configured for the interface.

Specifies whether IP forwarding is enable on this interface. Disabling IP forwarding on an interface will result in packets which are to be forwarded on that interface being dropped and ICMP error messages being generated for the packets.

Specifies the protocol to be used to obtain IP address for this interface. This object is valid only when ifIpAddrAllocMethod is set to dynamic (3). Currently rarp (1) option is not supported. The assigned value will be effective only when the interface admin status changes

A list of all the interfaces in the system with IVR related configurations. This table is an extension to the ifMainTable. The index to this table has the semantics of the ifMainIndex of the ifMainTable.

An entry containing IVR-related information applicable to a interface.

Indicates if this interface is a Bridged interface or not. A value of TRUE indicates that this interface is a Bridged interface and is capable of performing bridging of packets through this interface. A value of FALSE indicates that this interface is a Routed interface and is capable of performing routing of packets through this interface.

A string of octets containing one bit per VLAN. The first octet corresponds to VLANs with VlanId values 1 through 8; the second octet to VLANs 9 through 16 etc. The most significant bit of each octet corresponds to the lowest VlanId value in that octet. This is the set of vlans configured by management to associate with the management interface.

A string of octets containing one bit per VLAN. The first octet corresponds to VLANs with VlanId values 1 through 8; the second octet to VLANs 9 through 16 etc. The most significant bit of each octet corresponds to the lowest VlanId value in that octet. This is the set of vlans configured by management to dis-associate from the management interface. Get operation is not allowed for this object.

A list of secondary IP addresses configured over the interfaces registered with IP. This table is a extension to the ifMainTable.

This is the interval (in seconds) after which a learnt router port entry will be purged. For each router port learnt, this timer runs for RouterPortPurgeInterval seconds.When the timer expires, the learnt router port entry is purged. However if control messages are received from the router before the timer expiry, then the timer is restarted.

This is the interval (in seconds) after which a learnt port entry will be purged. For each port on which rsysort has been received this timer runs for PortPurgeInterval seconds. This timer will be restarted whenever a rsysort message is received from a host on the specific port. If the timer expires, then , the learnt port entry will be purged from the multicast group.

This timer is used when proxy-reporting is disabled,the switch then has to suppress multiple IGMPv2/ MLDv1 report messages for the same group from being forwarded to the router. This is the interval (in seconds) within which report messages for the same multicast group will not be forwarded. The ReportForwardTimer is per multicast group. This timer is started as soon as a report message for that group is forwarded out. Within this ReportForwardInterval if another report for the same group arrives, that report will not be forwarded.

When the switch receives leave message on a port, it sends group specific query to check if there are any other interested receivers for the group. This attribute defines the maximum number of queries sent by the switch before deleting the port from the group membership information in the forwarding database. If the maximum retry count exceeds sysSnoopRetryCount, then the port will be deleted from the multicast group membership information in the forwarding database and received leave message will be forwarded onto the router ports if there are no interested receivers for the group.

The value of this attribute defines the time period with which the switch will send group specific queries on a port to check if there are any intersted receivers.
