Disabling Up/Down Log Output on a Port
An Ethernet port has three physical link statuses: Up, Down, and Administratively Down. For status
transition conditions, refer to the description of the display brief interface command in Basic Port
Configuration Command.
When the physical link status of an Ethernet port changes between Up and Down or Up and
Administratively Down, the switch will generate Up/Down log and send the log information to the
terminal automatically by default. If the status of Ethernet ports in a network changes frequently, large
amount of log information may be sent to the terminal, which consumes more network resources.
Additionally, too frequent log information is not convenient for you to view.
You can limit the amount of the log information sent to the terminal by disabling the Up/Down log output
function on some Ethernet ports selectively. For information about log output settings, refer to the
Information Center module.
