Figure 11-2 shows the order in which the discard decisions are made.
Figure 11-2 How Frame Processing Affects Transmit Bridge Port Statistics
Setting the
Multicast Limit
You can assign a multicast packet firewall threshold to a bridge port on the
Switch 2200 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 7: Bridging Extensions in the
SuperStack™ II Switch 2200 Operation Guide.
Default value 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 port type.
2 Enter
Ethernet, FDDI, or all.
You are prompted for port number(s).
3 Enter the number(s) of the port(s) or
all to set the threshold for all ports
on the bridge.
You are prompted for a new value for each port you specified.
