Chapter 36 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 gigabitethernet2/0/1
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
Beginning with Cisco IOS Release 12.2(52)SE, the commands listed in
apply to both IPv4
and IPv6 traffic when the dual IPv4 and IPv6 SDM templates are used.
To display standard QoS information, use one or more of the privileged EXEC commands in
Step 5
show mls qos interface
[
interface-id
]
queueing
Verify your entries.
Step 6
copy running-config startup-config
(Optional) Save your entries in the configuration file.
