ExtremeWare XOS 11.5 Command Reference Guide
1836
enable igmp
enable igmp {vlan <vlan name>} {IGMPv1 | IGMPv2 | IGMPv3}
Description
Enables IGMP on a router interface. If no VLAN is specified, IGMP is enabled on all router interfaces.
Syntax Description
Default
Enabled, set to IGMPv2 compatibility mode.
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, IP hosts respond to the query, and group registration is maintained.
IGMPv2 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 unicast or IP multicast routing.
Example
The following command enables IGMPv2 on the VLAN
accounting
:
enable igmp vlan accounting
The following command enables IGMPv3 on the VLAN
finance
:
enable igmp vlan finance igmpv3
