We are deploying Cisco NAC IB Virtual GW for wireless but since this is the first time to deploy NAC on wireless environment I am totally lost. The version of NAC is 4.1.3.1. On the NAC Manager I configured the VLAN Mapping and Managed Subnet. On the WLC clients are authenticating to an ACS 5.0 using PEAP. The switch is configured as per NAC deployment guide for NAC IB VGW. Now when we change the VLAN on the WLC to be the AUTH VLAN the client are not able to access anything they are acquiring IP from the WLC. My question is how did the WLC redirect the traffic to the NAC. On wired environment SNMP is used right but how about the wireless, how will I configure the WLC to send the traffic to the NAS. Radius accounting is configure on the WLC and is pointing to the NAS. Attached is the topology.

Renato,


Do you have anywhere on your network interface vlan 215 defined? Even in shutdown state and no ip address, do you have a definition of interface vlan 215?

Renato,


Please open a TAC case so an engineer can do a sanity check of your settings.
