Figure 13-2 How Frame Processing Affects Transmit Bridge Port Statistics
You can assign a multicast packet firewall threshold to a bridge port on an
ESM or EFSM to limit the forwarding rate of multicast traffic originating on
the Ethernet segment connected to the port. For more information about
the multicast packet firewall, see Chapter 8: LANplex Bridging Extensions in
the LANplex 6000 Operation Guide.
The default is zero (0), which means that no threshold is set.
To set the multicast limit:
1 From the top level of the Administration Console, enter:
bridge port multicastLimit
You are prompted for slot number(s).
2 Enter the number(s) of the slot(s) or
in the system.
You are prompted for port type.
