rate limiting

[carl_townshend]

Hi all, Is there a rate limting feature on cisco switches for broadcasts etc? if so what amount of traffic does it look for before shutting down the port ?

Carl,

Depends on the model, for 35xx/29xx:-

Interface xx

port storm-control broadcast action filter or shutdown

port storm-control broadcast trap - send a syslog

port storm-control broadcast threshold rising 5 falling 3 the number to inidcate and issue - the number to indicate the issue has passed.

On 37xx:-

interface xx

storm-control broadcast level pps 5 3 - packets per second or

storm-control broadcast level 3.00 2.00 percentage of interface speed

storm-control action trap or shutdown

All the above work for Broadcast, Unicast & Multicast

HTH.
