CEF

I need to enable cef on my 2500. It does not recognize the command. Do I need to be at a certain IOS level? Does 2500 support CEF?

Thanks.

Hi

CEF is disabled by default, excluding these platforms:

CEF is enabled on the Cisco 7100 series router.

CEF is enabled on the Cisco 7500 series Internet router.

Distributed CEF is enabled on the Cisco 6500 series router

Distributed CEF is enabled on the Cisco 12000 series Internet router.

Re: CEF

You are right. I downloaded 12.1(20). It's up and running.

Thank you very much.
