logging information.

By default, all ports are allowed to
generate link up/down logging
information when the port state changes.
NOTE:
With this feature applied to a port, when the state of the port changes, the system does not generate port
link up/down logging information. In this case, you cannot monitor the port state changes conveniently.
Therefore, H3C recommends that you use the default configuration in normal cases.
