In conjunctions with ASC does the NAS server have to be a Cisco product or hardware or can it be exempt from the scheme of a wireless LAN. If so can the NAS just be a radius server. Are applications or devicws needed?
Are you wondering if Cisco Secure ACS requires a Cisco NAS? No. CS ACS is standard Radius and Ciscos TACACS+ so you can use it with any NAS. Do I understand your question correctly? If not, can you clarify?
