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
>> IGMP# snoop
>> IGMP Snoop# add 1
>> IGMP Snoop# apply
3.
Enable IGMPv3 Snooping (optional).
>> IGMP Snoop# igmpv3
>> IGMP V3 Snoop# ena
4.
Apply and save the configuration.
>> IGMP V3 Snoop# apply
>> IGMP V3 Snoop# save
5. View dynamic IGMP information.
>> /info/l3/igmp
>> IGMP Multicast# dump
Note: Local groups (224.0.0.x) are not snooped and will not appear.
