storm-control ingress
(interface)
Limits ingress traffic on a specified interface.
Syntax

{

no storm-control ingress

Parameters
-
broadcast
- Specifies that the command will operate on broadcast traffic only.
-
unknown-unicast
- Specifies that the command will operate on unknown-unicast traffic only.
-
multicast
- Specifies that the command will operate on multicast traffic only.
-
limit-bps
- Specifies that the value given to the rate parameter is in
bits per second. If the traffic on the interface reaches this rate, no more
traffic (for the traffic type specified) is allowed on the interface.
- rate
- Specifies the amount of traffic allowed, either in bits per
second or a percentage of the capacity of the interface,
depending on which parameter was chosen with the rate.
- If you are specifying rate in bps, enter an integer from 0 to
10000000000. Because each application-specific integrated
circuit (ASIC) may support different bit granularity, bit rates
are rounded up to the next achievable rate.
- If you are specifying rate in percent of interface capacity,
enter an integer from 0 to 100.
Modes
Interface configuration mode
Usage Guidelines
This command limits the amount of broadcast,
unknown unicast, and multicast (BUM) ingress traffic on a specified interface.
If you want to modify an active BUM storm control configuration, you must first disable it, then issue the
storm-control ingress command again with the new parameters.
Enter
no storm-control ingress to disable BUM storm control for a particular traffic type on an interface.
Examples
This example configures storm control on an
Ethernet interface, with a rate limited to 1000000 bps.
device(config)# interface ethernet 1/2
device(conf-if-eth-1/2)# storm-control ingress broadcast 1000000
