storm-control ingress (interface)

Limits ingress traffic on a specified interface.

Syntax

storm-control ingress { broadcast | unknown-unicast | multicast } limit-bps | rate
no storm-control ingress { broadcast | unknown-unicast | multicast }

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
