I have a closed network of 3 switches and 40 computers. 35 of those computers (Windows 7 x64 Professional) need to be plugged into any of the 24 ports on 2 of the switches at any time depending on the need and location of the user. I want to secure the switch to only allow these specific computers to connect. If another computer plugs in I want the switch to disable the port.
On previous small networks with no movement I configured each port with Port Security and the correct MAC Address of the computer. But for this I have more MACs than the Port Security table can handle. I was thinking about using 802.1X but I don't have a router on this system of which I am told I need for 802.1X. When I Google information for 802.1X configuration I end up with a lot of information on Wireless of which we don't use.
So my question is can I do 802.1X without a router and if so is there information on how to configure a server if needed? I have the switches setup with RADIUS authentication to access the SSH and console which works great.
Switches are HP ProCurve 2910al-24G.
