Performance Impact of massive CAR on NPE-400.

Hi,

It is understood that massive CAR is the best to be done by NSE-1. It is graceful if you can share your experience on using over 20 CAR on a sub-interface on NPE-400. (CPU% consuming on your case)

In my case, I need to configure 60 CAR on two sub-interfaces. (30 CAR per sub-interface). Each CAR has 1 to 2 ACL to specify the policed traffic and the rate-limited bandwidth of each CAR is 128kbps. I am afraid the CPU is pull very high when the traffic is not very high, say, 1Mbps.

Thanks,

Cliff

Re: Performance Impact of massive CAR on NPE-400.

The CPU can vary depending on the type of traffic and the amount of traffic coming and going in the router. Because of the linear search for the matching rate-limit statement, the CPU load increases with the number of rate policies.
