Viewing IGMPv3 cache

View the IGMPv3 specific data corresponding to each interface, port, and multicast group pair on a router.

About this task

You can view IGMP information on a VRF instance the same way you view the Global Router except that you must first launch the appropriate VRF context.

In the navigation pane, expand the following folders: Configuration > IP.
Click IGMP.
Click the IGMPv3 Cache tab to view the IGMPv3 cache information.

IGMPv3 Cache field descriptions

Use the data in the following table to use the IGMPv3 Cache tab.


Name	Description
GroupAddress	Specifies the Multicast group Address (Class D) that others want to join. A group address can be the same for many incoming ports.
IfIndex	An unique value to identify a physical interface or a logical interface (VLAN), which has received Group reports from various sources.
InPort	An unique value to identify a physical interface or a logical interface (VLAN), which has received Group reports from various sources.
ModeExpiryTimer	Represents the time remaining before the interface EXCLUDE state expires and the interface state transitions to INCLUDE mode. This value is applicable only to IGMPv3-compatible nodes.
Version1HostTimer	Specifies the time remaining until the local router assumes that there are no longer any IGMP version 1 members on the IP subnet attached to this interface. This entry only applies to IGMPv1 hosts. Upon hearing any IGMPv1 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.
Version2HostTimer	Specifies the time remaining until the local router assumes 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. Assuming no IGMPv1 hosts have been detected, the local router does not ignore any IGMPv2 Leave messages for this group that it receives on this interface.
SourceFilterMode	Specifies the current group state, applicable to IGMPv3-compatible nodes. The value indicates whether the state is INCLUDE or EXCLUDE.
