Monitoring reception of IGMP general query
messages
You can configure the IGMP proxy agent to monitor the reception of IGMP
general query messages on an interface. If an IGMP general query message is
not received on the interface within a specified time interval, IGMP generates
an igmpGeneralQueryNotReceivedEvent SNMP trap ({ enterprises(1)
alliedTelesyn(207) mibObject(8) brouterMib(4) atRouter(4) traps(2)
igmpTraps(1) 1 }) containing the ifName object for the interface, and the
following log message:
To enable monitoring on an interface and set the time interval, use the
command:
set ip igmp interface=interface
querytimeout={none|0|1..65535}
To display information about IGMP and the IGMP proxy agent, use the
command:
show ip igmp
