4 Command Line Interface

Command Usage

Depending on your network connections, IGMP snooping may not always be able to locate the IGMP querier. Therefore, if the IGMP querier is a known multicast router/switch connected over the network to an interface (port or trunk) on your router, you can manually configure that interface to join all the current multicast groups.

Example

The following shows how to configure port 11 as a multicast router port within VLAN 1:

Console(config)#ip igmp snooping vlan 1 mrouter ethernet 1/11 Console(config)#

show ip igmp snooping mrouter

This command displays information on statically configured and dynamically learned multicast router ports.

Syntax

show ip igmp snooping mrouter [vlan vlan-id]

vlan-id- VLAN ID (Range: 1-4094)

Default Setting
