status of Ethernet ports in a network changes frequently, large amount of log information may be sent,
which increases work load of the log server and consumes more network resources.
You can limit the amount of the log information sent to the log server by disabling the Up/Down log
output function on Ethernet ports.
After you allow a port to output the Up/Down log information, if the physical link status of the port does
not change, the switch does not send log information to the log server but monitors the port in real time.

Required
By default, UP/Down log
information output is enabled.
Configuration example
# By default, a port is allowed to output the Up/Down log information. Execute the shutdown command
or the undo shutdown command on Ethernet 1/0/1, and the system outputs Up/Down log information
of Ethernet 1/0/1.

# After you disable Ethernet 1/0/1 from outputting Up/Down log information and execute the shutdown
command or the undo shutdown command on Ethernet 1/0/1, no Up/Down log information is output
for Ethernet 1/0/1.
