When the maximum number of groups is reached on a port, the switch can
take one of two actions; either “deny” or “replace.” If the action is set to
deny, any new IGMP join reports will be dropped. If the action is set to
replace, the switch randomly removes an existing group and replaces it
with the new multicast group.
