i know how to peer WLC and ACS for RADIUS using ip addresses. But how i can configure to register WLC in ACS by WLC mac address (and not using the IP). I can see an option in the WLC (Security/Radius/Authenticatoin and there is an option for "Calling Station ID") however, i need some help how to tell ACS server that registers WLC as RADIUS client with the MAC address and not WLC IP.
That is correct.
This Attribute allows the NAS to send in the Access-Request packet the phone number that the call came from, using Automatic Number Identification (ANI) or similar technology. It is only used in Access-Request packets.
