Configures This command is available on the ExtremeSwitching X440-G2, X450-G2, X460-G2, X465, X590, X620, X670-G2, X690, X695, X870, 5320, 5420, 5520 series switches. ports to receive the traffic from a multicast group, even if no MLD joins have been received on the port.

Syntax Description

vlan_name Specifies a VLAN name.
port_list Specifies one or more ports or slots and ports. On a SummitStack, it can be a list of slots (nodes) and ports. On a standalone switch, it can be one or more port numbers. In the form 1, 2, 3-5, 2:5, 2:6-2:8.
IPv6_grp_ipaddress Specifies the multicast group IPv6 address.



Usage Guidelines

Use this command to forward a particular multicast group to VLAN ports. In effect, this command emulates a host on the port that has joined the multicast group. As long as the port is configured with the static entry, multicast traffic for that multicast group is forwarded to that port.

The switch sends proxy MLD messages in place of those generated by a real host. The proxy messages use the VLAN IPv6 address for source address of the messages. If the VLAN has no IPv6 address assigned, the proxy MLD message uses 0::0 as the source IP address.


The following example configures a static MLD entry so the multicast group ff02::1:1 is forwarded to VLAN marketing on ports 2:1-2:4:

configure mld snooping marketing ports 2:1-2:4 add static group ff02::1:1


This command was first available in ExtremeXOS 11.2.
