ipv6 mld snooping (Interface)
The ipv6 mld snooping (Interface) command enables MLD Snooping on an
interface. If an interface has MLD Snooping enabled and it becomes a
member of a port-channel (LAG), MLD Snooping functionality is disabled
on that interface. MLD Snooping functionality is re-enabled if the interface is
removed from a port-channel (LAG).
