1-9After you allow a port to output the Up/Down log information, if the physical link status of the port doesnot change, the switch does not send log information to the log server but monitors the port in real time.Disable Up/Down log output on a portTable 1-10 Disable UP/Down log output on a portOperation Command RemarksEnter system view system-view —Enter Ethernet port view interface interface-typeinterface-number —Disable a port from outputtingUP/Down Log Information undo enable log updownRequiredBy default, UP/Down loginformation output is enabled.Configuration example# By default, a port is allowed to output the Up/Down log information.

Once it finds that a type of traffic exceedsthe specified upper threshold, it blocks this type of traffic on the port or directly shuts down the port,and outputs trap/log information according to your configuration.
