I have a small project to authenticate around 100 users to access the network. We are planning to use the Cisco NAC appliance. Just to clarify (I have seen some post but I am not sure of the right answer) Do I need 2 separate appliances, one as server and the other as controller; or I just need one doing both tasks?
U need 2 devices to scatter this service. 1 will act as server who will push all policies to the end clients & the other will work as manager where the config will be done.
Rate if it helps
You need two appliances to make it work. One manager and one server.
There is an excellent book from the Cisco Press on the NAC Appliance by James Heary which will provide you with plenty of details and background on setting up the appliances.
Hope this helps.
