debug port port
Privileged EXEC mode
Global configuration mode
Use this command to monitor a specific physical port with the debug port up-down or
debug port hw-state
commands.
When the
debug port hw-state command is enabled after the
debug port port command, the output similar to the following example is displayed.
device# debug port port 1/1/2 monitor port 1/1/2 device# debug port hw-state
If port 1/1/2 is disabled, an output similar to the following is displayed.

The
debug port up-down command disables or enables a port to get output information of the specified port.
When the debug port up-down command is enabled after the
debug port port command, output similar to the following example is displayed.
device# debug port port 1/1/32 monitor port 1/1/32 device# debug port up-down
If port 1/1/32 is disabled, an output similar to the following is displayed.
