Dell PowerConnect ArubaOS 6.0 Command Line Interface | Reference Guide interface vlan ip igmp proxy | 255
interface vlan ip igmp proxy
interface vlan <vlan>
ip igmp snooping|{proxy fastethernet|gigabitethernet <slot>/<port>}
Description
This command enables IGMP and/or IGMP snooping on this interface, or configures a VLAN interface for
uninterrupted streaming of multicast traffic.
Syntax
Usage Guidelines
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 the controller. If IGMP snooping is configured on some of the interfaces, there is a greater
chance that multicast information transfers may be interrupted.
Example
The following example configures IGMP proxy for vlan 2. IGMP reports from the controller would be sent to the
upstream router on fastethernet port 1/3.
(host) (conf)# interface vlan 2
(conf-subif)# ip igmp proxy fastethernet 1/3
Related Commands
This release of ArubaOS supports version 1 of the Multicast Listener Discovery (MLD) protocol (MLDv1).
MLDv1, defined in RFC 2710, is derived from version 2 of the IPv4 Internet Group Management Protocol
(IGMPv2)
Issue the command interface vlan <vlan> ipv6 mld to enable the MLD protocol and allow an IPv6 router to
discover the presence of multicast listeners on directly-attached links. Use the CLI command interface vlan
<vlan> ipv6 mld snooping, and the IPv6 router will send multicast frames to only those nodes that need to
receive them.
Command History
This command was introduced in ArubaOS 3.4
Parameter Description
snooping
Enable IGMP snooping.
The IGMP protocol enables an router to discover 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.
proxy
Enable IGMP on this interface.
fastethernet
Enable IGMP proxy on the FastEthernet (IEEE 802.3) interface.
gigabitethernet
Enable IGMP proxy on the GigabitEthernet (IEEE 802.3) interface.
<slot>/<port>
Any command that references a Fast Ethernet or Gigabit Ethernet interface requires that you
specify the corresponding port on the controller in the format <slot>/<port>.
The <slot> parameter is always 1. The <port> parameter refers to the network interfaces that
are embedded in the front panel of the W-3000 Controller Series Multi-Service Controller. Port
numbers start at 0, from the left-most position.
