HP A3100-8 v2 SI User Manual

To do… Use the command… Remarks
Set a multicast suppression
threshold
multicast-suppression { ratio | pps
max-pps | kbps max-bps }
Optional
By default, all multicast traffic is
allowed to pass through an
interface.
Set a unicast suppression
threshold
unicast-suppression { ratio | pps
max-pps | kbps max-bps }
Optional
By default, all unknown unicast
traffic is allowed to pass through
an interface.
NOTE:
If you set a storm suppression threshold in both Ethernet interface view and port group view, the one
configured last takes effect.
Configuring storm control on an Ethernet Interface
Storm control compares broadcast, multicast, and unknown unicast traffic regularly with their respective
traffic thresholds on an Ethernet interface. For each type of traffic, storm control provides a lower
threshold and a higher threshold.
For management purposes, you can configure the interface to send threshold event traps and log
messages when monitored traffic exceeds the upper threshold or falls below the lower threshold from the
upper threshold.
When the traffic on an interface exceeds its higher threshold, the switch does either of the following
actions, depending on your configuration:
• Blocking the particular type of traffic and forwarding other types of traffic. Even though the interface
does not forward the blocked traffic, it still counts the traffic. When the blocked traffic is detected
dropping below the threshold, the interface begins to forward the traffic.
• Shutting down the interface automatically. The interface is shut down automatically and stops
forwarding any traffic. To bring up the interface, use the undo shutdown command or disable the
storm control function.
Follow these steps to configure the storm control function on an Ethernet interface:
