H-REAP APs and fast roaming for 7921 Phone

[graham.fleming]

Hey guys,

We have some remote H-READ APs at a branch office and a 7921 phone which drops calls/loses audio when roaming between APs.

We are just using WPA2 without any 802.1x or CCKM/PKC.

Do we absolutely have to set up a radius server/8021.x/EAP to enable fast roaming?

We had 2 AP's autonomous with WPA2 before and roaming didn't seem to be an issue. We now have 4 APs over WLC in the same office and the phone calls are very unstable.

Thanks for any input

Graham,

You'll want to configure the HREAP Group for the APs at the site. Is allows the AP to share the PMK for fast roaming.

This link talks about the feature, and has a link to configuration guide as well.

Thanks for the reply. Looks like H-REAP groups enable CCKM sharing but does CCKM not imply there is some form of EAP using RADIUS/external authentication?

Or are you certain that creating the H-REAP group and still using just PSK/WPA2 will fix roaming?

Thanks,

Graham

Fleming,

I think you are correct in pointing that out. How many clients are you expecting at the site? have to tried roaming on a open ssid? i would suggest you do that to see if there is some other issue than time taken for authentication.

Also, if the client count is going to be less than 100 and all of them are going to use wpa2/psk, you can try using local authentication whihc may reduce auth time.
