Using The Debug Autoqos Command - Cisco Catalyst 3550 series Software Configuration Manual

Using Debug Commands

Using the debug autoqos Command

You can use the debug autoqos privileged EXEC command to display quality of service (QoS)
commands that are automatically generated when automatic-QoS (auto-QoS) is enabled.
Beginning in privileged EXEC mode, follow these steps to display the QoS commands and enable
auto-QoS for voice over IP (VoIP) within a QoS domain:
Command
Step 1 debug autoqos
Step 2 configure terminal
Step 3
interface interface-id
Step 4 auto qos voip {cisco-phone | trust}
Step 5
end
Step 6
show auto qos interface interface-id
For more information about auto-QoS, see the
This example shows how to display the QoS commands that are automatically generated when auto-QoS
is enabled:
Switch# debug autoqos
AutoQoS debugging is on
Switch# configure terminal
Enter configuration commands, one per line.
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# auto qos voip cisco-phone

Purpose
Enable debugging for auto-QoS. When debugging is enabled, the
switch displays the QoS commands that are automatically generated
when auto-QoS is enabled or disabled.
Enter global configuration mode.
Enter interface configuration mode, and specify the interface that is
connected to a Cisco IP Phone. You also can specify the uplink
interface that is connected to another switch or router in the interior of
the network.
Enable auto-QoS.
The keywords have these meanings:
• cisco-phone—If the interface is connected to a Cisco IP Phone,
the QoS labels of incoming packets are trusted only when the IP
phone is detected.
• trust—The uplink interface is connected to a trusted switch or
router, and the VoIP classification in the ingress packet is trusted.
Return to privileged EXEC mode.
Verify your entries.
This command displays the auto-QoS configuration that was initially
applied; it does not display any user changes to the configuration that
might be in effect.
