CISCO-IGMP-SNOOPING-MIB
AI MIB Summary
The CISCO-IGMP-SNOOPING-MIB enables monitoring and management of IGMP Snooping states, group memberships, and source-specific filtering (IGMPv3) on Cisco Layer 2 switches. It provides visibility into critical metrics including multicast group counts, port-specific membership tables, proxy reporting status, and fast leave event counters to optimize multicast traffic forwarding.
The MIB module for IGMP Snooping feature.
Internet Group Management Protocol (IGMP) is the protocol used by IPv4 end hosts to indicate their interest in receiving multicast traffic for certain multicast groups to neighboring multicast routers. Version 3 of IGMP adds support for source based filtering; which means the end hosts can specifically indicate to receive or not-receive multicast packets from specific source addresses. This information is used by the multicast routers to restrict forwarding of multicast traffic for the host.
IGMP Snooping is a switch protocol. A switch that implements IGMP Snooping listens to the IGMP messages exchanged between the hosts and router, then provides selective transmission of multicast traffic based on multicast mac destination address or multicast group address. With IGMPv3 support, IGMP Snooping can potentially provide selective transmission of multicast data based on (source address, group address) onto the ports that are interested. In addition to this, IGMP Snooping can also provide proxy reporting, report suppression and fast leave capabilities.

cisIgmpSnoopingEnabledThis object indicates whether IGMP Snooping has been
enabled for the system.rw TruthValue -- Rsyntax INTEGER { -- true(1), -- false(2) -- } .1.3.6.1.4.1.9.9.263.1.1.1 |
cisV3ProcessEnabledAdminStatusThis object indicates the administrative status of IGMP v3
processing in the system. With the condition that IGMP
protocol has been enabled, a system will process IGMPv3
messages if this object is set to 'true', or it will process
only IGMPv1/v2 messages if this object is set to 'false'.rw TruthValue -- Rsyntax INTEGER { -- true(1), -- false(2) -- } .1.3.6.1.4.1.9.9.263.1.1.2 |
cisV3ProcessEnabledOperStatusThis object indicates the current operational status of IGMP
v3 processing in the system. This object is enabled if the
system is operating with IGMPv3 protocol. Value of this object
will be set to 'true' if the system is operating in IGMP v3,
and 'false' if it is operating in IGMPv1/v2.ro TruthValue -- Rsyntax INTEGER { -- true(1), -- false(2) -- } .1.3.6.1.4.1.9.9.263.1.1.3 |
cisFastLeaveEnabledThis object indicates whether Fast-Leave mechanism has been
configured to be enabled in the system. If Fast-Leave is
enabled in the switch, IGMP Snooping will prune the port on
which an IGMP leave message has been received without waiting
for the Group Specific Query to timeout to determine whether
there are any more hosts on that port for that group. If
cisV3ProcessEnabledOperStatus's value is 'false', this object
will not have any effect.rw TruthValue -- Rsyntax INTEGER { -- true(1), -- false(2) -- } .1.3.6.1.4.1.9.9.263.1.1.4 |
cisFastBlockEnabledThe object indicates whether Fast-Block mechanism has been
enabled for the system. This object only has effect if the
value of cisV3ProcessEnabledOperStatus is 'true'.rw TruthValue -- Rsyntax INTEGER { -- true(1), -- false(2) -- } .1.3.6.1.4.1.9.9.263.1.1.5 |
