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/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.
z
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:
To do...
Use the command...

—
Set the upper and lower
thresholds of
broadcast/multicast/unicast
traffic received on the port
storm-constrain { broadcast |
multicast | unicast }
max-packets min-packets
{ pps | kbps }
Required
Set the action to be taken when
a type of traffic received on the
port exceeds the upper
threshold.
storm-constrain control
{ block | shutdown }
Optional
By default, no action is taken
when a type of traffic reaches
the upper threshold.
Enable log/trap information to
be output when a type of traffic
received on the port exceeds
the upper threshold or falls
below the lower threshold
storm-constrain enable { log |
trap }
Optional
Enabled by default.

Optional
It is 10 seconds by default.
