Chapter 24 Configuring IGMP Snooping and MVR

Configuring MVR

	Command	Purpose
Step 3
	interface interface-id	Specify the Layer 2 port to configure, and enter interface configuration
		mode.
Step 4
	mvr type {source receiver}	Configure an MVR port as one of these:
		• source—Configure uplink ports that receive and send multicast data as
		source ports. Subscribers cannot be directly connected to source ports.
		All source ports on a switch belong to the single multicast VLAN.
		• receiver—Configure a port as a receiver port if it is a subscriber port and
		should only receive multicast data. It does not receive data unless it
		becomes a member of the multicast group, either statically or by using
		IGMP leave and join messages. Receiver ports cannot belong to the
		multicast VLAN.
		The default configuration is as a non-MVR port. If you attempt to configure
		a non-MVR port with MVR characteristics, the operation fails.
Step 5
	mvr vlan vlan-id group [ip-address]	(Optional) Statically configure a port to receive multicast traffic sent to the
		multicast VLAN and the IP multicast address. A port statically configured as
		a member of a group remains a member of the group until statically removed.
		Note In compatible mode, this command applies to only receiver ports. In
		dynamic mode, it applies to receiver ports and source ports.
		Receiver ports can also dynamically join multicast groups by using IGMP
		join and leave messages.
Step 6
	mvr immediate	(Optional) Enable the Immediate-Leave feature of MVR on the port.
		Note This command applies to only receiver ports and should only be
		enabled on receiver ports to which a single receiver device is
		connected.
Step 7
	end	Return to privileged EXEC mode.
Step 8
	show mvr	Verify the configuration.
	show mvr interface
	or
	show mvr members
Step 9
	copy running-config startup-config	(Optional) Save your entries in the configuration file.

To return the interface to its default settings, use the no mvr [type immediate vlan vlan-id group] interface configuration commands.

This example shows how to configure a port as a receiver port, statically configure the port to receive multicast traffic sent to the multicast group address, configure Immediate Leave on the port, and verify the results.

Switch(config)# mvr
