DGS-1250 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide level pps PPS-RISE [PPSLOW] level kbps KBPS-RISE [KBPS-LOW] level LEVEL-RISE [LEVELLOW] action shutdown action drop action none Specifies the threshold value in packets count per second. The range is from 0 to 2147483647. If the low PPS value is not specified, the default value is 80% of the specified risen PPS. Specifies the threshold value as a rate of bits per second at which traffic is received on the port. The range is from 0 to 2147483647. If the low KBPS is not specified, the default value is 80% of the specified risen KBPS. Specifies the threshold value as a percentage of the total bandwidth per port at which traffic is received on the port. The range is from 0 to 100. If the low level is not specified, the default value is 80% of the specified risen level. Specifies to shut down the port when the value specified for rise threshold is reached. Specifies to discards packets that exceed the risen threshold. Specifies not to filter the storm packets. Default By default, the broadcast, multicast, and unicast (DLF) storm controls are disabled. The default action taken when a storm occurs is to drop storm packets. Command Mode Interface Configuration Mode. Usage Guideline Use the storm control function to protect the network from the storm of broadcast packets, multicast packets, or unknown DA flooding packets. Enter the storm-control command to enable storm control for a specific traffic type on the interface. There are two ways to recover an error disabled port.  The user can use the errdisable recovery cause command to enable the automatic recovery of ports that were error disabled by storm control.  The user can manually recover the port by entering the shutdown command, followed by the no shutdown command for the port. There is only one meter mode (percentage, kbps or pps) that can take effect on an interface. On an interface, if the later specified meter mode option is different from the previous mode, the previous configured storms will reset to their default states (disabled in this specification). Due to hardware limitations, when the meter mode is percentage or kbps:  The action cannot be specified to the shutdown mode.  There are no traps and logs for the drop and none modes. This feature is unable to give the precise suppression level of the total bandwidth in percentage (0 to 100) of a specific port interface. The current calculation formula assumes that the packet size is 64 bytes. 465

level pps
PPS-RISE
[
PPS-
LOW
]
Specifies the threshold value in packets count per second. The range is from 0 to
2147483647. If the low PPS value is not specified, the default value is 80% of the
specified risen PPS.
level kbps
KBPS-RISE
[
KBPS-LOW
]
Specifies the threshold value as a rate of bits per second at which traffic is
received on the port. The range is from 0 to 2147483647. If the low KBPS is not
specified, the default value is 80% of the specified risen KBPS.
level
LEVEL-RISE
[
LEVEL-
LOW
]
Specifies the threshold value as a percentage of the total bandwidth per port at
which traffic is received on the port. The range is from 0 to 100. If the low level is
not specified, the default value is 80% of the specified risen level.
action shutdown
Specifies to shut down the port when the value specified for rise threshold is
reached.
action drop
Specifies to discards packets that exceed the risen threshold.
action none
Specifies not to filter the storm packets.
Default
By default, the broadcast, multicast, and unicast (DLF) storm controls are disabled.
The default action taken when a storm occurs is to drop storm packets.
Command Mode
Interface Configuration Mode.
Usage Guideline
Use the storm control function to protect the network from the storm of broadcast packets, multicast packets, or
unknown DA flooding packets. Enter the
storm-control
command to enable storm control for a specific traffic type
on the interface.
There are two ways to recover an error disabled port.
The user can use the
errdisable recovery cause
command to enable the automatic recovery of ports that
were error disabled by storm control.
The user can manually recover the port by entering the
shutdown
command, followed by the
no
shutdown
command for the port.
There is only one meter mode (percentage, kbps or pps) that can take effect on an interface. On an interface, if the
later specified meter mode option is different from the previous mode, the previous configured storms will reset to
their default states (disabled in this specification).
Due to hardware limitations, when the meter mode is percentage or kbps:
The action cannot be specified to the shutdown mode.
There are no traps and logs for the drop and none modes.
This feature is unable to give the precise suppression level of the total bandwidth in percentage (0 to 100) of a
specific port interface. The current calculation formula assumes that the packet size is 64 bytes.
