Field Description
VLAN Indicates the VLAN on which IGMP is
configured.
Query Intvl Specifies the frequency (in seconds) at
which host query packets are transmitted on
the interface.
Vers Specifies the version of IGMP configured on
this interface.
Oper Vers Specifies the version of IGMP running on this
interface.
Querier Specifies the IP address of the IGMP querier
on the IP subnet to which this interface is
attached.
Query MaxRspT Indicates the maximum query response time
(in tenths of a second) advertised in IGMPv2
queries on this interface.
Wrong Query Indicates the number of queries received
whose IGMP version does not match the
Interface version. You must configure all
routers on a LAN to run the same version of
IGMP. Thus, if queries are received with the
wrong version, a configuration error occurs.
Joins Indicates the number of times a group
membership was added on this interface.
Robust Specifies the robust value configured for
expected packet loss on the interface.
LastMbr Query Indicates the maximum response time (in
tenths of a second) inserted into group-
specific queries sent in response to leave
group messages, and is also the amount of
time between group specific query
messages. Use this value to modify the leave
latency of the network. A reduced value
results in reduced time to detect the loss of
the last member of a group. This does not
apply if the interface is configured for
IGMPv1.
Send Query Indicates whether the ip igmp send-query
feature is enabled or disabled. Values are
YES or NO. Default is disabled.
The following table describes the output of the command show ip igmp snooping.
