Process Switching in Routers

Unanswered Question

Looking for a white paper or SRND document that categorizes router commands into those that are process switched and those that can be fast switched or cef.

Main concern is with a router that is running as a firewall and doing NAT/PAT and IP Inspect. My guess is that these processes are process switched in the 2800/3800 series routers.

I want to recommend the right size for the custiomer.


Thanks.

Richard-


Here's a product performance sheet. I hope this helps in what you are looking for. If you ever find that magical sheet, please share it!

Thanks. I did have this sheet already. What I am looking for is what thing on the router puts things into process switching vs fast switching.


Specificly, on the security side, is this all process switched for NAT/PAT and IP Inspect?

I don't recall seeing a nice fact sheet that notes what features are process switched and which are fast switched. I recall I have seen occasional mention of a feature being moved from process switched to fast switched in a IOS upgrade note.
