A value of 0 disables the timer. A switch with a disabled timer never
times out inactive host nodes or multicast routers.
4 - Maximum Multicast Groups
Specifies the maximum number of multicast groups the switch will
learn. 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
to 255 groups. The default is 64 multicast groups.
5 - Multicast Router Port(s)
Specifies the port on the switch to which a multicast router is detected.
You can let the switch determine this automatically by selecting Auto
Detect, or you can specify the port yourself by entering a port number.
To select Auto Detect, enter “0” (zero) for this parameter. You can
specify more than one port.
Your changes are immediately activated on the switch.
Note
Option “6 - View Multicast Hosts List” is described in ”Displaying a
List of Host Nodes”, next. Option “7 - View Multicast Routers List” is
described in “Displaying a List of Multicast Routers” on page 331.
