Wireless Roaming

[Dmitry Podtikhov]

Hi,

I have the following setup:

Several autonomous Cisco APs, PEAP authentification with radius-based VLAN assignement and WPA2-AES encryption. Is it possible to provide fast roaming between my APs so that the whole process of re-authentification with radius server does not occur?

Is CCKM supported in my case (with dynamic vlan assignement)?

Hi,

When using security in IOS APs you need WDS to achieve Fast roaming.

Basically, there is a master AP (WDS AP) that controls RRM and the authentications. All other APs are infra-structure APs and report to the WDS.

This makes it possible to centralize the associated users so that when a user roams, it does not need to re-authenticate and the roaming is fast.

Please find more information here:
