Monitoring IGMP

Monitoring the performance of your IGMP traffic allows you to diagnose any potential issues on your switch. This helps you utilize bandwidth more efficiently by setting the switch to forward IP multicast traffic only to connected hosts that request multicast traffic.

Refer to the CEE Command Reference for complete information about the commands in this section.

To monitor IGMP snooping, perform the following procedure in EXEC or privileged EXEC mode.

1.Enter the show ip igmp groups command to display all information on IGMP multicast groups for the switch.

Use this command to display the IGMP database, including configured entries for either all groups on all interfaces, or all groups on specific interfaces, or specific groups on specific interfaces.

switch#show ip igmp groups

2. Use the show ip igmp statistics command to display the IGMP statistics for a VLAN or interface.

switch#show ip igmp statistics interface vlan 1

3.Use the show ip igmp mrouter to display multicast router (mrouter) port related information for all VLANs, or a specific VLAN.

switch#show ip igmp snooping mrouter

- or -

switch#show ip igmp snooping mrouter interface vlan 1

4.Use the show ip igmp interface command to display information relating to the IGMP configuration on the specified VLAN interface.

switch#show ip igmp interface vlan 100

5.When you have reviewed the IGMP statistics for the switch, refer to “Configuring IGMP” on page 128 or “Configuring IGMP snooping querier” on page 129 to make any needed corrections.

NOTE

Refer to the CEE Command Reference for additional information on IGMP CLI commands.
