Disabling Up/Down Log Output on a Port 103
Disabling Up/Down
Log Output on a Port
An Ethernet port has two physical link statuses: UP and Down. When the physical
link status of an Ethernet port changes, the switch will send log to the log server,
which in turn acts accordingly. If the 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.
n
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.
Disable Up/Down log
output on a port
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.
