Hi.
I need some performance and scalability numbers and limitations of ASR9k ISM card for NAT44. Documentation says "at least 10 Gbps full-duplex bandwidth throughput". Some other presentation are mentioning 15 Gbps but I think this is probably pps limitation and not bandwidth.
So my question is:
Thanks

Hi Omadon,
1) It would be about 5.5 - 6 Mpps per ISM. It may vary a little bit based on the packet length and other parameters like logging, etc.
2) It is cumulative value (for both I2O + O2I traffic)
3) Yes, you would need 2 ServiceApp pairs for maximum throughput. With 1 pair of ServiceApp, you would achieve 50% of throughput.
4) There will be drops at internal ports. It won't be reflected in any "show" XR CLI.
regards,
Somnath.
