debug pm
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.
