Chapter 33 Configuring QoS
Displaying Standard QoS Information
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 gigabitethernet0/1
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
