igmp enable (interface)
This command enables IGMP Snooping on a selected interface. If an interface that has IGMP
Snooping enabled is enabled for routing or is enlisted as a member of a LAG (port channel),
IGMP Snooping functionality will be disabled on that interface. IGMP Snooping
functionality will subsequently be re-enabled if routing is disabled or LAG membership is
removed from that interface.
