Rogue Access Points
Hi is there a way to scan for rogue access points and possibly block someone from plugging one into a network? I use Cisco Switches, unsure if there is a command to prevent this.
Thanks,

Your best defense is disabling DHCP. Then they would have to be abale to setup as a static ip.
You could try some of these to see if you detect unknown devices

You could use a product like GFI LANGuard or SolarWinds User Device Tracker. These do more detection and auditing, but that is an important first step. Once you get an alert that rogue device has been plugged in, you can go in a disable that port in your switch or go unplug it manually.
To help minimize that risk on secure networks such has hospitals, all ports that are not currently in use are disabled, and a request to IT must be made to turn it on. May be overkill or not possible for you though, depends on your managements attitude usually.

Fortinet has some devices which will detect and then interfere with rogue access points, while providing you with controlled wireless. You can control with APs are OK, and then interfere with the others so they don't get used.

You could also setup port security on the access ports of your cisco switches. This limits the number of MAC addresses that can access a switch port.

I wont be able to spend any money. If you use port access, or the switch, could i block netgear and linksys mac addresses somehow?
