Hi Syed,

I see Mr.Greg post the request "Using in-Band L2 Real-IP VLAN Deployment" as similar to Figure 2-3 in this document:

http://www.cisco.com/en/US/docs/security/nac/appliance/configuration_guide/412/cas/s_deploy.html#wp1051105. and You recommend use CAS DHCP server auto-generate of /30 subnet advantage to fullfill this function. Now, We have customer also require same structure to deploy their CCA with Cisco wireless controller solution. We configure two managed Vlans on CAS server for WLC two vlans( guest and Employee ); but We face a problem; ie: Wireless clients on guest or employee vlan can't get the ip address dispatch from CAS DHCP server. We turn on the DHCP debug on WLC and can't find any IP dispatch out from CAS DHCP server. but if We use wire client ( PC direct connect the switch VLANs ) the ip address can be dispatch from CAS DHCP server. Do You know if any limitation for WLC works with CAS DHCP server ? please advise ! Many Thanks !
