Description
Select the type of storm attack that will be controlled here. Options to choose from
are Broadcast, Multicast, and Unicast. When the action is configured as the
shutdown mode, the unicast refers to both known and unknown unicast packets;
that is, if the known and unknown unicast packets hit the specified threshold, the
port will be shutdown. Otherwise, unicast refers to unknown unicast packets.
Select the action that will be taken here. Options to choose from are:
• None - Specifies not to filter the storm packets.
• Shutdown - Specifies to shut down the port when the value specified for rise
threshold is reached.
• Drop - Specifies to discards packets that exceed the risen threshold.
Select the level type option here. Options to choose from are PPS, Kbps, and
Level.
Enter the rise packets per second value here. This option specifies the rise
threshold value in packets count per second. This value must be between 0 and
2147483647 packets per second. If the low PPS value is not specified, the default
value is 80% of the specified risen PPS.
Enter the low packets per second value here. This option specifies the low
threshold value in packets count per second. This value must be between 0 and
2147483647 packets per second. If the low PPS value is not specified, the default
value is 80% of the specified risen PPS.

Description
Enter the rise KBPS value used here. This option specifies the rise threshold
value as a rate of kilobits per second at which traffic is received on the port. This
value must be between 0 and 2147483647 Kbps.
Enter the low KBPS value used here. This option specifies the low threshold value
as a rate of kilobits per second at which traffic is received on the port. This value
must be between 0 and 2147483647 Kbps. If the low KBPS is not specified, the
default value is 80% of the specified risen KBPS.
