Chapter 37 Configuring QoS
Displaying Auto-QoS Information
Displaying Auto-QoS Information
To display the initial auto-QoS configuration, use the
show auto qos
[
interface
[
interface-id
]]
privileged EXEC command. To display any user changes to that configuration, use the
show
running-config
privileged EXEC command. You can compare the
show auto qos
and the
show
running-config
command output to identify the user-defined QoS settings.
To display information about the QoS configuration that might be affected by auto-QoS, use one of these
commands:
•
show mls qos
•
show mls qos maps cos-dscp
•
show mls qos interface
[
interface-id
] [
buffers
|
queueing
]
•
show mls qos maps
[
cos-dscp
|
cos-input-q
|
cos-output-q
|
dscp-cos
|
dscp-input-q
|
dscp-output-q
]
•
show mls qos input-queue
•
show running-config
For more information about these commands, see the command reference for this release.
Configuring Standard QoS
Before configuring standard QoS, you must have a thorough understanding of these items:
•
The types of applications used and the traffic patterns on your network.
•
Traffic characteristics and needs of your network. Is the traffic bursty? Do you need to reserve
bandwidth for voice and video streams?
•
Bandwidth requirements and speed of the network.
•
Location of congestion points in the network.
