Wireless Security with ACS

Hi,

We have an Wireless implementation with Aironet 1240 and 1200 AP's. The security is done with WEPkey 128bits, and Mac-Authentication against an Central ACS Server, but I've a problem with the timing of authentication. Every time we roaming from on AP to another, the authentication is going again to the Central ACS. Is there a possibility of keeping the authentication even when roaming? do you have any example of configs? I guess the possibility is Fast Secure Roaming, but could you help me out?

Best Regards,

Jorge Sousa

Re: Wireless Security with ACS

Yes, your guess is correct. Fast secure roaming is supported by Cisco Aironet 1200 and 1100 Series access points in conjunction with Cisco or Cisco Compatible client devices. With fast secure roaming, authenticated client devices can roam securely at L2 from one access point to another without any perceptible delay during reassociation. Fast secure roaming supports latency-sensitive applications such as wireless voice over IP (VoIP).

I think the following documents might be helpful to you.
