Chapter 24 Configuring IGMP Snooping and MVR

Configuring IGMP Snooping

Beginning in privileged EXEC mode, follow these steps to add a Layer 2 port as a member of a multicast
group:

To remove the Layer 2 port from the multicast group, use the no ip igmp snooping vlan vlan-id static
mac-address interface interface-id global configuration command.

This example shows how to statically configure a blade server on a port:

Switch# configure terminal

Switch(config)# ip igmp snooping vlan 105 static 224.2.4.12 interface gigabitethernet1/0/1

Switch(config)# end

Enabling IGMP Immediate Leave

When you enable IGMP Immediate Leave, the switch immediately removes a port when it detects an
IGMP Version 2 leave message on that port. You should only use the Immediate-Leave feature when
there is a single receiver present on every port in the VLAN.

Note

Immediate Leave is supported only on IGMP Version 2 blade servers.

Beginning in privileged EXEC mode, follow these steps to enable IGMP Immediate Leave:

vlan-id is the multicast group VLAN ID. The range is 1 to
1001 and 1006 to 4094.

interface-id is the member port. It can be a physical
interface or a port channel (1 to 64).

Step 3
