Step 6
copy running-config startup-config
To return to the default setting, use the no srr-queue bandwidth limit interface configuration command.
This example shows how to limit the bandwidth on a port to 80 percent:
Switch(config)# interface gigabitethernet1/1
Switch(config-if)# srr-queue bandwidth limit 80
When you configure this command to 80 percent, the port is idle 20 percent of the time. The line rate
drops to 80 percent of the connected speed, which is 800 Mb/s. These values are not exact because the
hardware adjusts the line rate in increments of six.
Displaying Standard QoS Information
To display standard QoS information, use one or more of the privileged EXEC commands in

Purpose
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
32-15:
Purpose
Display QoS class maps, which define the match criteria to
classify traffic.
Display global QoS configuration information.
Display the aggregate policer configuration.
Display QoS settings for the ingress queues.
Display QoS information at the port level, including the buffer
allocation, which ports have configured policers, the queueing
strategy, and the ingress and egress statistics.
Display QoS mapping information.
Display QoS settings for the egress queues.
Display QoS policy maps, which define classification criteria for
incoming traffic.
Note
Do not use the show policy-map interface privileged
EXEC command to display classification information
for incoming traffic. The control-plane and interface
keywords are not supported, and the statistics shown in
the display should be ignored.
Display the DSCP transparency setting.
