name Specifies a VLAN name.



Usage Guidelines

IGMP is a protocol used by an IP host to register its IP multicast group membership with a router. Periodically, the router queries the multicast group to see if the group is still in use. If the group is still active, hosts respond to the query, and group registration is maintained.

IGMP is enabled by default on the switch. However, the switch can be configured to disable the generation and processing of IGMP packets. IGMP should be enabled when the switch is configured to perform IP multicast routing.

This command disables IGMPv2 and IGMPv3.


The following example disables IGMP on VLAN accounting:

disable igmp vlan accounting
