Description |
|---|---|
Interface |
Specifies the interfaces that participate in the IGMP protocol |
Adm Admin Status |
Displays the administrative state for the IGMP protocol on this interface |
Oper Oper Status |
Displays the current operational state of IGMP protocol on the interface |
Querier |
Displays the address of the IGMP querier on the IP subnet to which the interface is attached |
Querier Up Time |
Displays the time since the querier was last elected as querier |
Querier Expiry Timer |
Displays the time remaining before the querier ages out. If the querier is the local interface address, the value will be zero. |
Cfg/Opr Version Admin/Oper version |
Cfg — The configured version of IGMP running on this interface. For IGMP to function correctly, all routers on a LAN must be configured to run the same version of IGMP on that LAN. Opr — The operational version of IGMP running on this interface. If the cfg value is 3 but all of the routers in the local subnet of this interface use IGMP version v1 or v2, the operational version will be v1 or v2. |
Num Groups |
Displays the number of multicast groups which have been learned by the router on the interface |
Policy |
Displays the policy that is to be applied on the interface |
Group Address |
Displays the IP multicast group address for which this entry contains information |
Up Time |
Displays the time since this source group entry got created |
Last Reporter |
Displays the IP address of the source of the last membership report received for this IP Multicast group address on this interface. If no membership report has been received, this object has the value 0.0.0.0. |
Mode |
The mode is based on the type of membership report(s) received on the interface for the group. In the 'include' mode, reception of packets sent to the specified multicast address is requested only from those IP source addresses listed in the source-list parameter of the IGMP membership report. In 'exclude' mode, reception of packets sent to the specific multicast address is requested from all IP source addresses except those listed in the source-list parameter. |
V1 Host Timer |
The time remaining until the local router will assume that there are no longer any IGMP version 1 members on the IP subnet attached to this interface. Upon hearing any IGMPv1 Membership Report, this value is reset to the group membership timer. While this time remaining is non-zero, the local router ignores any IGMPv2 Leave messages for this group that it receives on this interface. |
V2 Host Timer |
The time remaining until the local router will assume that there are no longer any IGMP version 2 members on the IP subnet attached to this interface. Upon hearing any IGMPv2 Membership Report, this value is reset to the group membership timer. While this time remaining is non-zero, the local router ignores any IGMPv3 Leave messages for this group that it receives on this interface. |
Type |
Indicates how this group entry was learned. If this group entry was learned by IGMP, it will be set to ‟dynamic”. For statically configured groups, the value will be set to 'static'. |
Compat Mode |
Used in order for routers to be compatible with earlier version routers. IGMPv3 hosts MUST operate in version 1 and version 2 compatibility modes. IGMPv3 hosts MUST keep state per local interface regarding the compatibility mode of each attached network. A host's compatibility mode is determined from the Host Compatibility Mode variable which can be in one of three states: IGMPv1, IGMPv2 or IGMPv3. This variable is kept per interface and is dependent on the version of General Queries heard on that interface as well as the Earlier Version Querier Present timers for the interface. |
