NETGEAR 8800 Chassis Switch CLI Manual enable igmp enable igmp {vlan } {IGMPv1 | IGMPv2 | IGMPv3} Description Enables IGMP on a router interface. If no VLAN is specified, IGMP is enabled on all router interfaces. Syntax Description vlan name IGMPv1 IGMPv2 IGMPv3 Specifies a VLAN name. Specifies the compatibility mode as IGMPv1. Specifies the compatibility mode as IGMPv2. Specifies the compatibility mode as IGMPv3. 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 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 enable igmp snooping enable igmp snooping {forward-mcrouter-only | {vlan} | with-proxy vr } Description Enables IGMP snooping on one or all VLANs. 1206 | Chapter 26.
