99. Storm Control Commands

99-1 storm-control
This command is used to configure the device to protect the device from broadcast, multicast, and DA
unknown packet storm attacks. Use the no form of this command to restore the function to its default
settings.
storm-control {{broadcast | multicast | unicast} level {pps PPS-RISE [PPS-LOW] | kbps KBPS-
RISE [KBPS-LOW] | LEVEL-RISE [LEVEL-LOW]} | action {shutdown | drop | none}}
no storm-control {broadcast | multicast | unicast | action}
Parameters
broadcast
multicast
unicast
level pps PPS-RISE [PPS-
LOW]
level kbps KBPS-RISE [KBPS-
LOW]
level LEVEL-RISE [LEVEL-
LOW]
action shutdown
action drop
action none
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.
Command Default Level
Level: 12.
Usage Guideline
Specifies to set the broadcast rate limit.
Specifies to set the multicast rate limit.
Specifies that when the action is configured as the shutdown mode,
the unicast refers to both known and unknown unicast packet, 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.
Specifies the threshold value in packets count per second. The range
is from 1 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 1 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 1 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.
