IGMP Snooping

Static multicast router

A static multicast router (Mrouter) can be configured for a particular port on a particular VLAN. A static Mrouter does not have to be learned through IGMP Snooping.

You can configure static Mrouters on any switch port except the management port 17. The switch supports up to total of sixteen static Mrouters.

When you configure a static Mrouter on a VLAN, it replaces any dynamic Mrouters learned through IGMP Snooping.

IGMP Snooping configuration example

This section provides steps to configure IGMP Snooping on the switch, using the Command Line Interface (CLI) or the Browser-based Interface (BBI).

Configuring IGMP Snooping (CLI example)

1.Configure port and VLAN membership on the switch, as described in the “Configuring ports and VLANs (CLI example)” section in the “VLANs” chapter.

2.Add VLANs to IGMP Snooping and enable the feature.

>> /cfg/l3/igmp/on	(Globally turn IGMP on)
>> IGMP# snoop	(Select IGMP Snooping menu)
>> IGMP Snoop# add 1	(Add VLAN 1 to IGMP Snooping)
>> IGMP Snoop# apply	(Make your changes active)

3.Enable IGMPv3 Snooping (optional).

>>	IGMP	Snoop# igmpv3	(Select	IGMPv3	menu)
>>	IGMP	V3 Snoop# ena	(Enable	IGMPv3	Snooping)

4.Apply and save the configuration.

>>	IGMP	V3	Snoop#	apply	(Apply the	configuration)
>>	IGMP	V3	Snoop#	save	(Save your	changes)

5.View dynamic IGMP information.

>> /info/l3/igmp					(Select IGMP Information menu)
>> IGMP Multicast# dump					(Show IGMP Group information)
Note: Local groups (224.0.0.x) are not					snooped	and will	not appear.
Source		Group		VLAN	Port	Version	Mode Expires		Fwd
---------------		---------------		------	-------	--------	----	----------	---
224.10.2.0		232.1.0.0		2	18	V3	INC	4:17	Yes
228.12.1.0		232.1.0.4		2	18	V3	INC	4:18	Yes
*		235.2.0.1		3	21	V3	INC	-	No
*		236.1.0.2		3	21	V3	EXC	-	Yes
>> /info/l3/igmp/mrouter					(Access Mrouter information menu)
>> Mrouter# dump					(Show IGMP Group information)
VLAN	Port	Version	Expires	Max Query Resp. Time QRV QQIC
------	-------	--------	--------	-------------------- --- ----
1	21	V2	static	unknown		-	-
2	20	V3	4:09	128		2	125

These commands display information about IGMP Groups and Mrouters learned through IGMP Snooping.
