Displaying IGMP snooping information
This section describes the show commands for IGMP snooping.
Displaying IGMP errors
To display information about possible IGMP errors, enter the show ip multicast error command.
Brocade# show ip multicast error
snoop SW processed pkt: 173, up-time 160 sec
Syntax: show ip multicast error
The following table describes the output from the show ip multicast error command.
Displaying IGMP group information
To display information about IGMP groups, enter the show ip multicast group command.
In this example, an IGMPv2 group is in EXCLUDE mode with a source of 0. The group only excludes
traffic from the 0 (zero) source list, which actually means that all traffic sources are included.
To display detailed IGMP group information, enter the show ip multicast group detail command.
