What is the default working mode of a combo port and the command used to set its working mode

A combo port can work either as an optical port or an electrical port.

By default, a combo interface works in auto mode.

You can run the combo-port { auto| copper| fiber } command in the interface view to set the working mode of a combo port. In the command, auto allows a combo port to automatically select the working mode, copper configures a combo port to work as an electrical port, and the fiber configures a combo port to work as an optical port.
