ASR 1000 series and legacy protocols

Unanswered Question
Mar 17th, 2008

In the ASR 1000 Series, are legacy protocols such as IPX, SNA, etc... punted to Route Processor for processing ? If yes, is that rate-limited to prevent hogging of the CPU?

I have this problem too.

Yes, legacy protocol packets are processed by the RP, you can rate-limit all traffic going to RP via Control Plane Processing (CoPP) and we can rate-limit/police traffic on the embedded services processor (ESP) using the QuantumFlow Processor's (QFP's) Traffic Manager.

Hope this helps!

This link has some good information about the ASR including its support for legacy protocols:

Note that 3 out of 4 software packages (functionally what we call feature sets in normal IOS) state that they do not support legacy protocols. And all 4 software packages state that they do not support SNA switching.
