It depends what you want to compare. You need to pick some topics to compare first, then ask for some help. I could compare a Nexus 7k vs a Juniper EX8200 (http://www.glcomp.com/documents/glc/ju/Juniper-EX8200-vs-Cisco-Nexus-7000.pdf)
But that might not be what you want. Here are some suggestions for topics to compare:
- high/mid/low range routing performance
- high/mid/low range switching performance
- ios vs junos, who is the buggiest
- routing - who offers more features to which target market?
- switching - who offers more features to which target market?
- cisco vs juniper market share in routing
- cisco vs juniper market share in switching
- cisco vs juniper market share in firewalls
- who offers better product support, what is the support like for different products?
There's tonnes of topics, so pick what you want to compare. I think you will find more relevant information when you then search for the different topics!
Well i have to "buy" devices, so i have to compare devices. So i think the mid range routing/switching(?) performace will be my choice (and maybe IOS-Junos).
And the other half of my problem.
First i though that i'll use a 3945E router and 2960-24-S catalyst switches with some AP541N Access point from cisco side. This is all theoretical so the budget can be unlimited, but reasonable.
I don't know if the router is capable to serve 400 user. As i can see the router has gigabit ports to connect the switches and ISP.
(Sorry if this is a little bit off, but i learned ccna 5 years ago and i didn't used the knowledge since then.)
