Appendix B Catalyst 3750-X and 3560-X Switch Debug Commands

debug pm

Use the debug pm privileged EXEC command to enable debugging of port manager (PM) activity. The

port manager is a state machine that controls all the logical and physical interfaces. All features, such as

VLANs, UniDirectional Link Detection (UDLD), and so forth, work with the port manager to provide

switch functions. Use the no form of this command to disable debugging.

no debug pm {all | assert | card | etherchnl | hatable | messages | port | redundancy | registry |
