Chapter 32 Configuring Broadcast Suppression

Enabling Broadcast Suppression

To enable broadcast suppression for one or more ports, perform this task in privileged mode:
Task
Step 1 Configure the broadcast suppression threshold for
one or more ports as a percentage of total
bandwidth.
Step 2 Verify the broadcast suppression configuration.
Although you can specify the broadcast suppression threshold to 0.01 percent, not all modules adjust
Note
to that level of precision. Most thresholds vary between 0.01 percent and 0.05 percent. If you specify
a finer threshold, the threshold percent adjusts as closely as possible.
This example shows how to enable bandwidth-based broadcast suppression and verify the configuration:
Console> (enable) set port broadcast 3/1-6 75.25%
Port(s) 3/1-24 broadcast traffic limited to 75.25%.
Console> (enable) show port broadcast 3
Port
-------- --------------- --------------
3/1 75.25 %
3/2 75.25 %
3/3 75.25 %
3/4 75.25 %
3/5 75.25 %
3/6 75.25 %
3/7 0 %
3/8 0 %
3/90 %
3/10 0 %
3/110 %
3/120 %
This example shows how to limit the multicast and broadcast traffic to 80 percent for port 2 on
module 1 and verify the configuration:
Console> (enable) set port broadcast 1/2 80% multicast enable
Port 1/2 broadcast and multicast
Console> (enable) show port broadcast 1/2
Port
-------- --------------- -------------------- --------- -------
1/2
Console> (enable)
