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 ports. 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.
