If an interface has IGMP Snooping enabled and you enable this interface for routing or
enlist it as a member of a port-channel (LAG), IGMP Snooping functionality is
disabled on that interface. IGMP Snooping functionality is re-enabled if you disable
routing or remove port-channel (LAG) membership from an interface that has IGMP
Snooping enabled.
