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.

Configuring Storm Control on a Port
The storm control function is used to control traffic received on an Ethernet port.
z With traffic upper and lower thresholds specified on a port, the system periodically collects
statistics about the broadcast/multicast traffic on the port. Once it finds that a type of traffic exceeds
the 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.
