If the switch does not detect any queries from a multicast router
during the specified time interval, it assumes that the router is no
longer active on the port.
Maximum Multicast Groups
Specifies the maximum number of multicast groups the switch
learns. The range is 1 to 256 groups. The default is 64 multicast
groups.
This parameter is useful with networks that contain a large
number of multicast groups. You can use the parameter to
prevent the switch’s MAC address table from filling up with
multicast addresses, leaving no room for dynamic or static MAC
addresses. The range is 1 address to 256 addresses. The default is
64 multicast addresses.
