ExtremeWare XOS 11.5 Command Reference Guide
1882
enable mld snooping
enable mld snooping {forward-mcrouter-only | vlan <name>}
Description
Enables MLD snooping on the switch.
Syntax Description
Default
Enabled.
Usage Guidelines
If a VLAN is specified, MLD snooping is enabled only on that VLAN, otherwise MLD snooping is
enabled on all VLANs.
A VLAN must have an IPv6 address to support MLD.
Two MLD snooping modes are supported:
●
The
forward-mcrouter-only
mode forwards all multicast traffic to the multicast router (that is, the
router running PIM).
●
When not in the
forward-mcrouter-only
mode, the switch forwards all multicast traffic to any IP
router (multicast or not), and any active member port to the local network that has one or more
subscribers.
NOTE
The forward-mcrouter-only mode for MLD snooping is enabled/disabled on a switch-wide basis, not on a per-VLAN
basis. In other words, all the interfaces enabled for MLD snooping are either in the forward-mcrouter-only mode or in
the non-forward-mcrouter-only mode, and not a mixture of the two modes.
To change the MLD snooping mode from the non-
forward-mcrouter-only
mode to the
forward-
mcrouter-only
mode, use the command:
enable mld snooping forward-mcrouter-only
To change the MLD snooping mode from the
forward-mcrouter-only
mode to the non-
forward-
mcrouter-only
mode, use the command:
disable mld snooping forward-mcrouter-only
forward-mcrouter-only
Specifies that the switch forwards all multicast traffic to the multicast router
only.
name
Specifies a VLAN.
