First of all, you have atm overhead, makes a 155 mbps to be really 120 mbps or so.

Secondly, a 3845 might get close to max circuit utilization, but with significant CPU usage.

A 3825 would probably melt much before.


hope this helps, please rate post if it does!

I really appreciate your effort, but i found it in a presentation on CEC; ISR are CPU based so it could reach higher performance, but basically the answer was yes.


Thanks!!! have a greate weekend!

Here's attached "your" official numbers.


As you see for smaller packet size linerate cannot be reached. So in general don't count on a 3825 to be able "to fill the pipe" and still have CPU to spare. It won't.
