Catalyst 2960 Switch Debug Commands
This appendix describes the debug privileged EXEC commands that have been created or changed for use with the Catalyst 2960 switch. These commands are helpful in diagnosing and resolving internetworking problems and should be enabled only under the guidance of Cisco technical support staff.
Because debugging output is assigned high priority in the CPU process, it can render the system unusable. For this reason, use the
debug commands only to troubleshoot specific problems or during troubleshooting sessions with Cisco technical support staff. It is best to use the
debug commands during periods of lower network traffic and fewer users. Debugging during these periods decreases the likelihood that increased
debug command processing overhead will affect system use.
debug auto qos
Use the debug auto qos privileged EXEC command to enable debugging of the automatic quality of service (auto-QoS) feature. Use the no form of this command to disable debugging.
debug auto qos
no debug auto qos
Syntax Description
This command has no keywords or arguments.
Defaults
Auto-QoS debugging is disabled.
Command Modes
Privileged EXEC

12.2(25)FX |
This command was introduced. |
Usage Guidelines
To display the QoS configuration that is automatically generated when auto-QoS is enabled, enable debugging before you enable auto-QoS. You enable debugging by entering the debug auto qos privileged EXEC command.
The undebug auto qos command is the same as the no debug auto qos command.
Examples
This example shows how to display the QoS configuration that is automatically generated when auto-QoS is enabled:
Switch# debug auto qos
AutoQoS debugging is on
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# auto qos voip cisco-phone
