Storm Control Commands
58-1 storm-control
This command is used to enable the storm suppression. Use the no form of the command to disable the storm
suppression.
storm-control {broadcast | multicast | unicast} {pps
pps-rise
[
pps-low
] | level
level-rise
[
level-low
]}
no storm-control {broadcast | multicast | unicast}
Parameters
broadcast
Specifies to enable the broadcast storm suppression function on the port.
multicast
Specifies to enable the multicast storm suppression function on the port.
unicast
Specifies to enable the unknown unicast storm suppression function on the port.
pps
pps-rise
{
pps-low
}
Specifies the threshold as packet count per second at which traffic is received on the
port. The range is 1 to 14881000.
level
level-rise
{
level-low
}
Specifies the threshold as a percentage of total bandwidth per port at which traffic is
received on the port. The range is 1 to 100.
Default
The default setting of broadcast, multicast, and unicast storm control are disabled.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 15
Usage Guideline
Too many broadcast, multicast or unknown unicast packets received on a port may
cause storm and thus slow network.
A device can implement the storm suppression to a broadcast, a multicast, or a
unicast storm respectively. When excessive broadcast, multicast or unknown unicast
packets are received, the switch temporarily prohibits forwarding of relevant types of
packets until data streams are recovered to the normal state (then packets will be
forwarded normally).
The low threshold must be equal to or less than the rise threshold suppression value.
If don’t configure the low threshold, it default equal to rise threshold.
Use
show storm-control
to display configuration. Use
storm-control action
to
config action.
Note:
1. The
storm-control
option is not supported on a link aggregation port.
2. The
level-based
storm control option has certain errors for the packets in the
length of more than 64 bytes. The longer the packet length is, the greater the
comparable error value is.
Example
This example shows how to enable the multicast storm suppression on port 1 with a
1000 pps rising suppression and a 500 pps falling suppression.
