Displaying IGMP snooping errors

To display information about possible IGMP errors, enter the show ip multicast error command.

device#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.

SW processed pkt

The number of multicast packets processed by IGMP snooping.

up-time

The time since the IGMP snooping is enabled.

Displaying IGMP group information

To display default, maximum, current, and configured values for system maximum parameters, use the
show default values command. The following output example does not show complete output; it
shows only IGMP group values.

device(config)#show default values

System Parameters     Default    Maximum    Current    Configured

igmp-snoop-group-add  4096       8192       5000       5000      

To display information about IGMP groups, enter the show ip multicast group command.

device#show ip multicast group

p-:physical, ST:static, QR:querier, EX:exclude, IN:include, Y:yes, N:no

VL70 : 3 groups, 4 group-port, tracking_enabled

      group            p-port   ST     QR     life mode    source

1     224.1.1.2        1/33     no     yes    120  EX      0

2     224.1.1.1        1/33     no     yes    120  EX      0

3     226.1.1.1        1/35     yes    yes    100  EX      0

4     226.1.1.1        1/33     yes    yes    100  EX      0

In this example, an IGMP V2 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 for a specific group, enter the show ip multicast group
detail command.

device#show ip multicast group 226.1.1.1 detail

Display group 226.1.1.1 in all interfaces in details.
