Displaying IGMP Snooping Information
This example shows how to display the host types and ports of a group in VLAN 1:
Switch# show ip igmp snooping groups vlan 10 226.6.6.7
Vlan Group Version Ports
---------------------------------------------------------
10 226.6.6.7 v3 Fa7/13, Fa7/14
Switch>
This example shows how to display the current state of a group with respect to a source IP address:
Switch# show ip igmp snooping groups vlan 10 226.6.6.7 sources
Source information for group 226.6.6.7:
Timers: Expired sources are deleted on next IGMP General Query
SourceIP Expires Uptime Inc Hosts Exc Hosts
-------------------------------------------------------
2.0.0.1 00:03:04 00:03:48 2 0
2.0.0.2 00:03:04 00:02:07 2 0
Switch>
This example shows how to display the current state of a group with respect to a host MAC address:
Switch# show ip igmp snooping groups vlan 10 226.6.6.7 hosts
IGMPv3 host information for group 226.6.6.7
Timers: Expired hosts are deleted on next IGMP General Query
Host (MAC/IP) Filter mode Expires Uptime # Sources
-------------------------------------------------------------
175.1.0.29 INCLUDE stopped 00:00:51 2
175.2.0.30 INCLUDE stopped 00:04:14 2
This example shows how to display summary information for an IGMPv3 group:
Switch# show ip igmp snooping groups vlan 10 226.6.6.7 summary
Group Address (Vlan 10) : 226.6.6.7
Host type : v3
Member Ports : Fa7/13, Fa7/14
Filter mode : INCLUDE
Expires : stopped
Sources : 2
Reporters (Include/Exclude) : 2/0
This example shows how to display the total number of group addresses learned by the system globally:
Switch# show ip igmp snooping groups count
Total number of groups: 54
This example shows how to display the total number of group addresses learned on VLAN 5:
Switch# show ip igmp snooping groups vlan 5 count
Total number of groups: 30
Displaying Multicast Router Interfaces
When you enable IGMP snooping, the switch automatically learns to which interface the multicast
routers are connected.
