Label |
Description |
|---|---|
|
The IP multicast group address for which this entry contains information. |
|
Specifies the type of membership reports received on the interface for the group. In 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. |
|
Indicates how this group entry was learned. If this group entry was learned by IGMP, the value is set to dynamic. For statically configured groups, the value is set to static. |
|
Specifies the IGMP mode. This is used so routers are 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 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. |
|
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. |
|
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. |
|
The source address for which this entry contains information. |
|
The time since the source group entry was created. |
|
The amount of time remaining before this entry will be aged out. |
|
Indicates the number of IGMP group and source specific queries received on this SAP. |
|
Indicates whether this entry is on the forward list or block list. |
|
Indicates the number of groups configured for this SAP. |
