interface vlan ip igmp

interface vlan

ip igmp {proxy {gigabitethernet } | port-channel } | snooping

Description

This command enables IGMP or IGMP snooping on this interface, or configures a VLAN interface for uninterrupted streaming of multicast traffic.

The newer IGMP proxy feature and the older IGMP snooping feature cannot be enabled at the same time, as both features add membership information to multicast group table. For most multicast deployments, you should enable the IGMP Proxy feature on all VLAN interfaces to manage all the multicast membership requirements on themanaged device. If IGMP snooping is configured on some of the interfaces, there is a greater chance that multicast information transfers may be interrupted.

This release ofArubaOSsupports version 1 of the MLD protocol (MLDv1). MLDv1, defined in RFC 2710, is derived from version 2 of the IPv4 IGMPv2. You can use the commandinterface vlan ipv6 mldto enable the MLD protocol and allow an IPv6 router to discover the presence of multicast listeners on directly-attached links. Use the CLI commandinterface vlan ipv6 mld snoopingfor the Pv6 router to send multicast frames to only those nodes that need to receive them.

Parameter	Description
proxy	Enable IGMP proxy for this interface.
gigabitethernet	Enable IGMP proxy on the specified GigabitEthernet (IEEE 802.3) interface.
port-channel	Enable IGMP proxy on the specified port channel.
snooping	Enable IGMP snooping. 说的IGMP协议允许一个路由器cover the presence of multicast listeners on directly-attached links. Enable IGMP snooping to limit the sending of multicast frames to only those nodes that need to receive them.

Example

The following example configures IGMP proxy for vlan 2. IGMP reports from themanaged devicewould be sent to the upstream router on gigabitethernet port 0/0/3.
