Displaying Auto-Qos Information; Auto-Qos Configuration Example - Cisco Catalyst 2950 Software Configuration Manual

Chapter 29 Configuring QoS
This example shows how to enable auto-QoS and to trust the QoS labels in incoming packets when the
device connected to the interface is detected as a Cisco IP Phone:
Switch(config)# interface fastethernet0/1
Switch(config-if)# auto qos voip cisco-phone
This example shows how to enable auto-QoS and to trust the QoS labels in incoming packets when the
switch or router connected to the interface is a trusted device:
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# auto qos voip trust

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:
•
•
•
•
For more information about these commands, see the command reference for this release.

Auto-QoS Configuration Example

This example is applicable only if your switch is running the EI.
Note
This section describes how you could implement auto-QoS in a network, as shown in
optimum QoS performance, auto-QoS should be enabled on all the devices in the network.
