DGS-1520 Series Gigabit Ethernet Smart Managed Switch Web UI Reference Guide Parameter From Port - To Port Type Action Level Type PPS Rise PPS Low Description Select the appropriate port range used for the configuration here. 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 1 and 2147483647 packets per second. 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 1 and 2147483647 packets per second. By default, this is 80% of the specified PPS Rise value. Click the Apply button to accept the changes made. After selecting the Kbps option as the Level Type, the following parameters are available. Figure 9-89 Storm Control Settings (Level Type - Kbps) Window The additional fields that can be configured in Storm Control Port Settings are described below: Parameter KBPS Rise KBPS Low 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 1 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 1 and 2147483647 Kbps. By default, this is 80% of the specified KBPS Rise value. Click the Apply button to accept the changes made.

Description
From Port - To Port
Select the appropriate port range used for the configuration here.
Type
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.
Action
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.
Level Type
Select the level type option here. Options to choose from are
PPS
,
Kbps
, and
Level
.
PPS Rise
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 1 and
2147483647 packets per second.
PPS Low
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 1 and
2147483647 packets per second. By default, this is 80% of the specified
PPS Rise
value.
