Limiting the Bandwidth on an Egress Interface
You can limit the bandwidth on an egress port. For example, if a customer pays only for a small percentage
of a high-speed link, you can limit the bandwidth to that amount.
The egress queue default settings are suitable for most situations. You should change them only when you
have a thorough understanding of the egress queues and if these settings do not meet your QoS solution. Note
Beginning in privileged EXEC mode, follow these steps to limit the bandwidth on an egress port. This procedure
is optional.
SUMMARY STEPS
1.
configure terminal
2.
interface interface-id
3. srr-queue bandwidth limit weight1
4.
end
5. show mls qos interface [ interface-id ] queueing
6. copy running-config startup-config
DETAILED STEPS
Purpose Command or Action
Enters global configuration mode. configure terminal
Example:
Switch# configure terminal
Step 1
Specifies the port to be rate-limited, and enters interface
configuration mode.
interface interface-id
Example:
Switch(config)# interface
Step 2
gigabitethernet2/0/1
Specifies the percentage of the port speed to which the port
should be limited. The range is 10 to 90. srr-queue bandwidth limit weight1
Example:
Switch(config-if)# srr-queue
Step 3
By default, the port is not rate-limited and is set to 100 percent.
To return to the default setting, use the no srr-queue
bandwidth limit
interface configuration command.
Note
bandwidth limit 80
