Monitoring and Maintaining IGMP Snooping and MVR
Command Purpose
show ip igmp snooping [vlan vlan-id] Displays 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 4096.
show ip igmp snooping groups [count |dynamic
[count] | user [count]]
Displays multicast table information for the switch or about a specific
parameter:
count—Displays the total number of entries for the specified
command options instead of the actual entries.
dynamic—Displays entries learned through IGMP snooping.
user—Displays only the user-configured multicast entries.
show ip igmp snooping groups vlan vlan-id
[ip_address | count | dynamic [count] |
user[count]]
Displays 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 4096.
count—Displays the total number of entries for the specified
command options instead of the actual entries.
dynamic—Displays entries learned through IGMP snooping.
ip_address—Displays characteristics of the multicast group with the
specified group IP address.
user—Displays only the user-configured multicast entries.
show ip igmp snooping mrouter [vlan vlan-id] Displays 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] Displays 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
Displays 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.
show ip igmp profile [profile number] Displays the specified IGMP profile or all the IGMP profiles defined on the
switch.
show mvr Displays MVR status and values for the switch—whether MVR is enabled
or disabled, the multicast VLAN, the maximum (256) and current (0
through 256) number of multicast groups, the query response time, and
the MVR mode.
