CISCO-MLD-SNOOPING-MIB: View SNMP OID List / Download MIB

This MIB module defines objects that describe IGMP/MLD snooping. It provides remote network management system the ability to manage the IGMP/MLD Snooping feature when snooping is operating at the system and port level. Virtual systems and related ports data can be accessed by NMS using appropriate SNMP context. E.g. in order to access data related to a particular L2VPN bridge domain system, the user shall specify on the SNMP request the SNMP context related to that particular bridge domain. Glossary of terms: GMI - Group Management Interval; it controls when the IGMP/MLD snooping expires stale group membership states. L2VPN - Layer 2 Virtual Private Network. IGMP - Internet Group Management Protocol. MLD - Multicast Listener Discovery. MRT - Max Response Time. TTL - Time To Live. PIM - Protocol Independent Multicast. TCN - Topology Change Notification. Querier - External IGMP/MLD router sending out queries which are flooded in the system (e.g a bridge domain). Internal Querier - Virtual Querier that solicits periodic membership reports by sending IGMP/MLD general queries out of all system ports. Winner/Looser Querier - A system can only have one active querier at a time, if the internal querier receives queries from another querier it performs querier election, the lowest IP address wins. G-Query - General IGMP/MLD Query. Solicitation - a global leave message with a NULL group multicast address, when the upstream router receives this solicitation, it immediately issues an general query.

This table lists IGMP/MLD configuration for each profile available on the system.

An entry describes a IGMP/MLD snooping profile; that is a set of configuration parameters that can be applied to either systems or ports. A peer SNMP entity may create a profile by setting an instance of cmsProfileStatus to 'createAndWait' or 'createAndGo'. Observe that an implementation that does not support these options must specify these limitations in an agent capabilities statement. Other management entities (e.g., the local console) may perform actions resulting in the creation of a member link. In these cases, the system must automatically create a row in the cmsProfileTable. A peer SNMP entity may destroy a profile by setting the corresponding instance of cmsProfileStatus to 'destroy'. Observe that an implementation that does not support this option must specify this limitation in an agent capabilities statement. Other management entities may perform actions resulting in the destruction of a profile. In these cases, the system must automatically destroy the corresponding row in the cmsProfileTable.

This object indicates a text string defining the name of the profile identified by cmsProfileIndex.

This object specifies the status of the row. The following columns must be valid before activating a row: - cmsProfileStorageType - cmsProfileSnoopMinVersion - cmsProfileIPAddrType - cmsProfileIPAddress - cmsProfileRobustnessVariable - cmsProfileInternalQuerier - cmsProfileLastMemberQueryCount - cmsProfileLastMemberQueryInterval - cmsProfileProxyReporting - cmsProfileReportSuppression - cmsProfileUnsolicitedReportTimer - cmsProfileFloodQueryCount - cmsProfileQuerySolicit - cmsProfileTTLCheck - cmsProfileRouterAlertCheck - cmsProfileIntQuerierMaxRespTime - cmsProfileIntQuerierQueryInterval - cmsProfileIntQuerierRobustnessVar - cmsProfileIntQuerierTCNQueryCount - cmsProfileIntQuerierTCNQueryIntrvl - cmsProfileIntQuerierExpiry - cmsProfileIntQuerierVersion - cmsProfileRouterGuard - cmsProfileStaticMRouter - cmsProfileImmediateLeave However, these objects specify valid default values. Thus, it is possible to use create-and-go row creation semantics without setting additional columns. An implementation must allow an EMS/NMS to modify any column when this column is 'active'

This object specifies the storage type of this conceptual row.

This object specifies the minimum IGMP or MLD version supported by snooping in the system where the profile is applied.

This object specifies the IP address type (IPv4 or IPv6) for the objects cmsProfileIPAddress

This object specifies the robustness-variable value used to calculate the group management interval (GMI): GMI = (robustness-variable * query-interval) + MRT

This object specifies the administrative status of the internal querier. A value of 'true' means that the internal querier feature is enabled.

This object specifies the profile member query count. This value is the number of group-specific queries IGMP/MLD snooping sends, in response to a leave message.

This object specifies the query interval, which should be the time gap between two consecutive group-specific queries.

This object specifies the configuration status of the report suppression feature. A value of 'true' means that the reports are suppressed.

This object specifies the administrative status of the alert check feature. A value of 'true', means IGMP/MLD snooping performs the validation before processing the message.

This object specifies the internal querier TCN query interval, which should be the time gap between two consecutive TCN queries

This object specifies the IGMP/MLD snooping router guard configuration status. A value of 'true' means that a port cannot be dynamically discovered as an mrouter

This object specifies the static multicast router administrative status. A value of 'true' means that the feature is enabled.

This object specifies the immediate leave administrative status. A value of 'true' means that IGMP/MLD snooping will remove a Layer 2 interface from the forwarding table entry immediately, without first sending group-specific queries to the port.

This table lists snooping configuration for each port.

An entry describes the configuration associated with a port. A peer SNMP entity may create a port config by setting an instance of cmsConfigPortStatus to 'createAndWait' or 'createAndGo'. Observe that an implementation that does not support these options must specify these limitations in an agent capabilities statement. Other management entities (e.g., the local console) may perform actions resulting in the creation of a member link. In these cases, the system must automatically create a row in the cmsConfigPortTable. A peer SNMP entity may destroy a port config by setting the corresponding instance of cmsConfigPortStatus to 'destroy'. Observe that an implementation that does not support this option must specify this limitation in an agent capabilities statement. Other management entities may perform actions resulting in the destruction of a profile. In these cases, the system must automatically destroy the corresponding row in the cmsConfigPortTable.
