DGS-3120-24TC:admin#
33-28 enable mld_snooping
Description
This command is used to enable MLD snooping on the Switch. The forward_mcrouter_only
function is disabled by default. The enable mld_snooping forward_mcrouter_only command will
enable the MLD snooping function and the forward multicast router only function.
If forward multicast router only is enabled, the Switch will forward all multicast traffic to the
multicast router, only. Otherwise, the Switch forwards all multicast traffic to any IP router.
Format
enable mld_snooping
Parameters
When the Switch receives an MLD report packet from a port, this port will be learned as a
member port of the multicast group that the port is reported, and the router will be a default
member of this multicast group. The multicast packet destined for this multicast group will be
forwarded to all the members of this multicast group.
Restrictions
Only Administrator, Operator and Power-User level users can issue this command.
