Field Description
Interface The interface for which data is to be displayed.
Multicast Group IP The IP multicast group address for which data is to be displayed.
Last Reporter The IP address of the source of the last membership report received for
the IP multicast group address on the selected interface.
Up Time The time elapsed since this entry was created.
Expiry Time The minimum amount of time remaining before this entry is aged out.
Version 1 Host Timer The time remaining until the local router assumes that no IGMP version
1 members are on the IP subnet attached to this interface. When an
IGMPv1 membership report is received, this timer is reset to the group
membership timer
. While this timer is non-zero, the local router ignores
any IGMPv2 leave messages for this group that it receives on the
selected interface.
This field is displayed only if the interface is
configured for IGMP version 1.
Version 2 Host Timer The time remaining until the local router assumes that no IGMP version
2 members are on the IP subnet attached to this interface. When an
IGMPv2 membership report is received, this timer is reset to the group
membership timer
. While this timer is non-zero, the local router ignores
any IGMPv1 and IGMPv3 leave messages for this group that it receives
on the selected interface.
This field is displayed only if the interface is
configured for IGMP version 2.

group on the specified interface.
