Disabling Up/Down Log Output on a Port

An Ethernet port has two physical link statuses: UP and Down. When the link status of an Ethernet port
changes, the device sends log information to the log server, which then acts accordingly. If the status of
Ethernet ports changes frequently, the device sends log information to the log server frequently,
burdening the log server and consuming plenty of network resources.
To solve this problem, you can disable the Up/Down log output function on some ports, so as to reduce
the quantity of log information output to the log server.
After you allow a port to output the Up/Down log information, if the physical link status of the port does
not change, the device does not send log information to the log server but monitors the port in real time.
Configuration tasks
Follow these steps to disable a port from outputting UP/Down log information:

shutdown command or the undo shutdown command on GigabitEthernet 1/0/1, and the system
outputs Up/Down log information of GigabitEthernet 1/0/1.
Use the command...
