Whether it is possible to configure the NAC with the following settings:
I am establishing this in a campus LAN environment.
I have a Cisco 4510R Layer 3 switch as the Core switch.
I have Cisco 3550 Layer 3 switch as the distribution switch
I have some unmanaged and managed switch as the Access layer Switches. All Desktop computers are connected in this access swtich only.
Distribution Switch and core switch is connected in the Routed backbone (Trunking is not configured between Distribution and Core)
Since I have unmanaged switches at the access layer and Core to Distribution is Routed backbone (Layer 3) i have decided to configure the NAC appliance in the following setup:
Layer 3 Inband Virtual Gateway
I request you to provide solution and configuration steps to achieve the following:
1. How to configure NAC Appliance for Layer3 Inband VirtualGateway
2. Users/Desktop computers should authenticate by username/password & Mac Address/IP address to get into the network. If the Users/Desktop computers do not match the IP address with MAC Address combination configured in the NAC appliance they should be in quarantine role.
