Enables IGMP on a router interface. If no VLAN is specified, IGMP is enabled on all router interfaces.
| vlan name | Specifies a VLAN name. |
| IGMPv1 | Specifies the compatibility mode as IGMPv1. |
| IGMPv2 | Specifies the compatibility mode as IGMPv2. |
| IGMPv3 | Specifies the compatibility mode as IGMPv3. |
Enabled, set to IGMPv2 compatibility mode.
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 multicast routing.
The following example enables IGMPv2 on the VLAN accounting:
enable igmp vlan accounting
The following example enables IGMPv3 on the VLAN finance:
enable igmp vlan finance igmpv3
This command was first available in ExtremeXOS 10.1.
The IGMPv1, IGMPv2, and IGMPv3 options were added in ExtremeXOS 11.2.
This command is available on platforms that support the appropriate license. For complete information about software licensing, including how to obtain and upgrade your license and which licenses support the IPv4 multicast feature, see the Switch Engine 32.3 Feature License Requirements document.
