storm-control
Use this command to set the rising threshold level for broadcast, multicast, or destination lookup failure traffic. The storm control action occurs when traffic utilization reaches this level.
Storm control is used to block the forwarding of unnecessary flooded traffic. A packet storm occurs when a large number of broadcast packets are received on a port. Forwarding these packets can cause the network to slow down or time out.
Use the no form of this command to disable storm control.
Note: Granularity of storm-control is around 18 kbps for lower values and it increases when configured with increase in rate. Deviation is expected +-7/8 % of rate configured for lower value rate changes.
Command Syntax
storm-control (broadcast|multicast|dlf) (level LEVEL | <0-1000000000>
(kbps|mbps|gbps) burst-size <1-33292>)
no storm-control (broadcast|multicast|dlf)
Parameters
broadcast
Broadcast rate limiting.
multicast
Multicast rate limiting.
dlf
Destination lookup failure limiting.
level
Sets the percentage of the threshold.
LEVEL
The percentage of the threshold; percentage of the maximum speed (pps) of the interface <0.0000-1000.0000>.
<0-1000000000>
Sets absolute threshold value <0-1000000000>
kbps
specifies the units of Kilobits per second.
mbps
specifies the units of Megabits per second.
gbps
specifies the units of Gigabits per second.
burst-size
Set burst size
<1-33292>
value of burst in kbps
Default
By default, storm control is disabled
Command Mode
Interface mode
Applicability
