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, Shutdown, and Drop. Selecting None specifies not to filter the storm packets. Selecting Shutdown specifies to shut down the port when the value specified for rise threshold is reached. Selecting 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.
