Command Usage
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.
