Appendix B Catalyst 3750 Switch Debug Commands
debug auto qos
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
Command History
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.
When you enable debugging, it is enabled only on the stack master. To enable debugging on a stack
member, you can start a session from the stack master by using the session switch-number privileged
EXEC command. Then enter the debug command at the command-line prompt of the stack member. You
also can use the remote command stack-member-number LINE privileged EXEC command on the stack
master switch to enable debugging on a member switch without first starting a session.
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 gigabitethernet2/0/1
Switch(config-if)# auto qos voip cisco-phone
21:29:41: mls qos map cos-dscp 0 8 16 26 32 46 48 56
21:29:41: mls qos
21:29:42: no mls qos srr-queue input cos-map
21:29:42: no mls qos srr-queue output cos-map
21:29:42: mls qos srr-queue input cos-map queue 1 threshold 3 0
21:29:42: mls qos srr-queue input cos-map queue 1 threshold 2 1
Release Modification
