Field Description
Interface The interface on which the IGMP is enabled.
IP Address The IP address of the selected interface.
Subnet Mask The subnet mask for the IP address of the selected interface.
Protocol State The operational state of IGMP on the selected interface, either

selected interface is attached.
Querier Status Indicates whether the selected interface is in querier or non-querier
mode.
Querier Up Time The time in seconds since the IGMP interface querier was last
changed.
Querier Expiry Time The time in seconds remaining before the other querier present timer
expires. If the local system is the querier
, this is zero.
Wrong Version Queries Received The number of queries that were received on the selected interface
with an IGMP version that does not match the IGMP version configured
for the interface, over the lifetime of the entry
. IGMP requires that all
routers on a LAN be configured to run the same version of IGMP.
Therefore, a configuration error is indicated if any queries are received
with the wrong version number.
Number of Joins Received The number of times a group membership was added on the selected
interface; that is, the number of times an entry for this interface was
added to the cache table.
This gives an indication of the amount of
IGMP activity on the interface.
Number of Groups The current number of entries for the selected interface in the cache
table.
