Hi Friend,

Cisco 3845 has 500,000 PPS fast switching capacity and a throughput of 256 Mbps.

The processor type info I am unable to find out for you.

HTH,

Can I ask how you've confirmed the max throughput is 256mb?. I can't find any reference on CCO to clarify this. In otherwords, what performance should I expect in/out the gigabit ports for straight routed traffic.

Hi,

In the Q&A it says "performance of 350-500 Kpps in light service environments with 64 byte packets".

500Kpps x 64bytes = 256Mbps

Whether you'd get this in practice is another matter - see the Miercom report:

Re: Processor type and forwarding performance

So at 1500byte packets, we could expect the full 1gb through the LAN interface? It's just that I can't find this confirmed anywhere, other than assuming it would perform at full rate in those cases. I know thats not general real life traffic, but I'm thinking of network archoves etc. Thanks.
