I am starting to "polish" the LAN here at my new work and since it's the 1st time I face sommething that big (almost 300 clients a switches, proxy) I would like to understand easily where I get weak points (read: 10mbit hubs hidden under desks) before starting to deploy important services like dhcp, dns and AD. I remember about a tool called ipers (or similar, can't remember well) who has a server and client part. I could put the server on our proxy and the client on a laptop anche check how the various floors and rooms are working.
Any hints on how to achieve this?
thanks!
