Configuring Storm Control On A Port - H3C S3100-52P Operation Manual

Operation Manual – Port Basic Configuration
H3C S3100-52P Ethernet Switch
When the physical link status of an Ethernet port changes between Up and Down or Up
and Administratively Down, the switch will generate Up/Down log and send the log
information to the terminal automatically by default. If the status of Ethernet ports in a
network changes frequently, large amount of log information may be sent to the
terminal, which consumes more network resources. Additionally, too frequent log
information is not convenient for you to view.
You can limit the amount of the log information sent to the terminal by disabling the
Up/Down log output function on some Ethernet ports selectively. For information about
log output settings, refer to the Information Center module.
Follow these steps to disable UP/Down log output on a port:
Enter system view
Enter Ethernet port view
Disable a port from
generating UP/Down log

1.1.12 Configuring Storm Control on a Port

The storm control function is used to control traffic received on an Ethernet port.
With traffic upper and lower thresholds specified on a port, the system periodically
collects statistics about the broadcast/multicast/unicast/ 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.
When a type of traffic on the port falls back to the specified lower threshold, the
system cancels the blocking of this type of traffic on the port or brings up the port to
restore traffic forwarding for the port, and outputs log/trap information according to
your configuration.
Follow these steps to configure storm control on a port:
Enter system view
Enter Ethernet port view
Set the upper and lower
thresholds of
broadcast/multicast/unicast
traffic received on the port
