Configuring IGMP Snooping

Configuring IGMP Snooping Parameters

Parameter	Description
Multicast router vpc-peer-link	Configures a static connection to a virtual port
	channel (vPC) peer link.

By default, the vPC peer-link is considered a multicast router port and the multicast packet is sent to the peer-link for each receiver VLAN.

To send the multicast traffic over a vPC peer-link to each receiver VLAN that has orphan ports, use the

no ip igmp snooping mrouter vpc-peer-link

command. If you use the no ip igmp snooping mrouter vpc-peer-linkcommand, the multicast traffic won’t be sent over to a peer-link for the source VLAN and receiver VLAN unless there is orphan port in the VLAN. The IGMP snooping mrouter vpc-peer-link should also be globally disabled on the peer VPC switch.

	Note	In Cisco NX-OS Release 5.0(3)N1(1), the
		no ip igmp snooping mrouter
		vpc-peer-linkcommand is not supported in
		topologies where there is dual-homed FEX
		attached to a Cisco Nexus 5000 Series
		switch.
Static group	Configures an interface belonging to a VLAN as a
	static member of a multicast group.

You can disable IGMP snooping either globally or for a specific VLAN.

Procedure

	Command or Action	Purpose
Step 1	switch# configure terminal	Enters configuration mode.
Step 2	switch(config)# ip igmp snooping	Globally enables IGMP snooping. The default is enabled.
		Note	If the global setting is disabled, then all VLANs are
			treated as disabled, whether they are enabled or not.
Step 3	switch(config)# vlan vlan-id	Enters VLAN configuration mode.
Step 4	switch(config-vlan)# ip igmp	Enables IGMP snooping for the current VLAN. The default
	snooping	is enabled.
		Note	If IGMP snooping is enabled globally, this command
			is not required.
