Storm Control in the access layer

Unanswered Question
Jul 3rd, 2010


Have a general question about the implementation of Storm Control in the access layer.

The answer is likely a "it depends" on your environment, but in gerneral what would be a good percentage to start with for implementing storm control in the access layer where end users/end user devices (printers, etc...) connect? Assuming the access switches are a mix of 3550/3560/3750 10/100. I was thinking around 50 percent to start with (for some broadcast storm protection), but was curious to hear from those that have implemented.



I have this problem too.

Hello Brandon,

we have used 1% on GE ports with /24 IP subnets

I could guess 10% on FE ports should be fine.

The size of the IP subnet counts

Hope to help

Hi Giuseppe,

Thanks for the reply. I do appreciate it.

I am also looking into setting up storm/broadcast control and very interested.  We have variously sized subnets as well as supernets.  How exactly would you factor in network size to setup some starting settings?

Thank you.
