IGMP AND IGMP SNOOPING COMMANDS
IP
IGMP TRUSTED
ip igmp trusted
Overview Use this command to allow IGMP to process packets received on certain trusted
ports only.
Use the no variant of this command to stop IGMP from processing specified
packets if the packets are received on the specified ports or aggregator.
Syntax
ip igmp trusted {all|query|report|routermode}
no ip igmp trusted {all|query|report|routermode}
Default By default, all ports and aggregators are trusted interfaces, so IGMP is allowed to
process all IGMP query, report, and router mode packets arriving on all interfaces.
Mode Interface mode for one or more switch ports or aggregators
Usage Because all ports are trusted by default, use this command in its no variant to stop
IGMP processing packets on ports you do not trust.
For example, you can use this command to make sure that only ports attached to
approved IGMP routers are treated as router ports.
Example To stop ports port1.0.3-port1.0.6 from being treated as router ports by IGMP, use
the commands:
awplus(config)# interface port1.0.3-port1.0.6
awplus(config-if)# no ip igmp trusted routermode
