Pls find the flow chart design for deploying NAC
Installing NAC for the first time, I m little bit confuse what design i shld choose:It is a corporate network with access switches,core switch,asa firewall,ACS.
I have a multi vendor switches in my network HP switches as well as Cisco on acces layer and on core i have a HP 5406,i have read the NAC book from cisco press.It says that u shld choose IN-band mode when u have a multi vendor switches in ur network.So what i m thinking is IN-band mode layer2 adjacency with real IP gateway or virtual IP.
But wherever i see the document on cisco website it is all for OOB network mode (real as well as virtual) i m not able to find any configuration example for IN-band layer2 adjacency in real ip gateway or virtual gateway.
Is it my thinking is wrong or please guide me which mode i shld choose.and route me to the proper configuration example.
Not sure I understand the question completely, but I can tell for sure that VPN is supported IB with RIP and VGW both. In VGW the VLANs are different on the trusted and untrusted side and worst case scenario, if a switch misbehaves or doesn't work "right" with NAC, you can place it in true edge deployment to make it work. In short, it's possible
