Displaying IGMP Snooping Information
To display IGMP snooping information, use one or more of the privileged EXEC commands in
Table 24-4.
For more information about the keywords and options in these commands, see the command reference
for this release.
Table 24-4 Commands for Displaying IGMP Snooping Information
Command Purpose
show ip igmp snooping [vlan vlan-id] Display the snooping configuration information for all VLANs on the
switch or for a specified VLAN.
(Optional) Enter vlan vlan-id to display information for a single VLAN.
The VLAN ID range is 1 to 1001 and 1006 to 4094.
show ip igmp snooping groups [count |dynamic
[count] | user [count]]
Display multicast table information for the switch or about a specific
parameter:
• count—Display the total number of entries for the specified
command options instead of the actual entries.
• dynamic—Display entries learned through IGMP snooping.
• user—Display only the user-configured multicast entries.
show ip igmp snooping groups vlan vlan-id
[ip_address | count | dynamic [count] |
user[count]]
Display multicast table information for a multicast VLAN or about a
specific parameter for the VLAN:
• vlan-id—The VLAN ID range is 1 to 1001 and 1006 to 4094.
• count—Display the total number of entries for the specified
command options instead of the actual entries.
• dynamic—Display entries learned through IGMP snooping.
• ip_address—Display characteristics of the multicast group with the
specified group IP address.
• user—Display only the user-configured multicast entries.
show ip igmp snooping mrouter [vlan vlan-id] Display information on dynamically learned and manually configured
multicast router interfaces.
Note When you enable IGMP snooping, the switch automatically
learns the interface to which a multicast router is connected.
These are dynamically learned interfaces.
(Optional) Enter vlan vlan-id to display information for a single VLAN.
show ip igmp snooping querier [vlan vlan-id] Display information about the IP address and receiving port for the
most-recently received IGMP query messages in the VLAN.
(Optional) Enter vlan vlan-id to display information for a single VLAN.
show ip igmp snooping querier [vlan vlan-id]
detail
Display information about the IP address and receiving port of the
most-recently received IGMP query message in the VLAN and the
configuration and operational state of the IGMP snooping querier in the
VLAN.
