CPU rate-limiting
Configuring outbound rate shaping for a specific priority
To configure the maximum rate at which outbound traffic is sent out on a port priority queue, enter
the following commands.
Brocade(config)#interface ethernet 1/1/2
Brocade(config-if-e10000-1/1/2)#rate-limit output shaping 500 priority 7
Syntax: [no] rate-limit output shaping value priority priority-queue
Specify 0-7 for priority-queue
Configuring outbound rate shaping for a trunk port
This feature is supported on individual ports of a static trunk group and on LACP trunk ports. To
configure the maximum rate at which outbound traffic is sent out on a trunk port, enter the
following on each trunk port where outbound traffic will be shaped.
Brocade(config)# trunk ethernet 1/1/3 to 1/1/6
Brocade(config-trunk-3-6)# config-trunk-ind
Brocade(config-trunk-3-6)# rate-limit output shaping ethernet 1/1/5 651
Brocade(config-trunk-3-6)# rate-limit output shaping ethernet 1/1/4 1300
The above commands configure an outbound rate shaper on port 1/1/4 and port 1/1/5.
Syntax: [no] rate-limit output shaping ethernet port value
Specify the port variable in stack-unit/slotnum/portnum format.
Displaying rate shaping configurations
To display the configured outbound rate shaper on a device, use the show rate-limit output-shaping
command.
The output lists the ports on a device, the configured outbound rate shaper (if any) for each port,
and the priority for a port.
CPU rate-limiting
Unnecessary traffic to the switch CPU lowers the efficiency of the CPU and delays handling of other
traffic that requires processing. CPU rate limiting is a CPU protection scheme which limits certain
traffic types.
