The following parameters can be viewed/modified in the bottom half of the window:
Parameter Description
Static Router Port
Tick the checkboxes below the corresponding port numbers to specify that the ports
are connected to multicast-enabled routers. This ensures that these ports will
forward all packets having the multicast-enabled router as the destination will
successfully reach the router, regardless of the protocol, e.t.c.
Forbidden Router Port
Tick the checkboxes below the corresponding port numbers to specify that the ports
are not being connected to multicast-enabled routers. This ensures that these ports
will not propagate outbound routing packets.
Dynamic Router Port
Tick the checkboxes below the corresponding port numbers to specify that the
Switch will automatically determine If the port is connected to a multicast-enabled
router or not.
After setting the previous parameters, click the Ap ply button in the bottom section of the window to allo w your changes to be
implemented.
