Displaying Standard Qos Information - Cisco WS-C3560-48PS-S Software Configuration Manual

Displaying Standard QoS Information

Beginning in privileged EXEC mode, follow these steps to limit the bandwidth on an egress port. This
procedure is optional.
Command
Step 1 configure terminal
Step 2
interface interface-id
Step 3
srr-queue bandwidth limit weight1
Step 4 end
Step 5
show mls qos interface [interface-id]
queueing
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 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 Mbps. 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

28-64
Purpose
Enter global configuration mode.
Specify the port to be rate limited, and enter interface configuration mode.
Specify the percentage of the port speed to which the port should be
limited. The range is 10 to 90.
By default, the port is not rate limited and is set to 100 percent.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
28-15:
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.
