I am wanting to perform a baseline of our core network performance. What i am particuarly interested in is how many packets per second the core switches are processing and the current backplane performance. We are using older 3550 stackable switches in our core. I am measuring CPU and interface statistics but I dont think this is providing me with the information i require. The CPU of the core switches sits at a very low 3% on average and looking at the interface statistics i cannot see any drops or failures.
Any advice would be appreciated.
