Roaming on three Cisco Aironet (AIR-AP-1231G)

Martin,

If all you want from the 1231s is the same functionality that you had with the ZyXELs, then just configure them the same way. I.e. use the same SSID on all 3 APs and same static WEP key.

Hi Aaron,

But will the access-points be able to "negotiate" with the two other access-points about who will take the wireless client.

The ZyXEL's have a special IP port where this communication is running.

No idea what those negotiations might be. In general, it's the client's decision to associate to a given AP. (Unless the ZyXELs are doing some kind of goofy Meru-ish "big BSSID" thing.)

The Cisco APs will by default chat amongst themselves via the IAPP protocol (UDP port 2887) to inform each other about roam events etc.

Oh, do put your APs on nonoverlapping 2.4GHz channels (i.e. 1, 6 and 11.)

Thank you for your answers Aaron, I appreciate that :-)

Last question, should I use the same channel on all three access-points? Anything else I should be aware of?

You will need wireless domain services (WDS) for fast secure roaming. 3 AP will be able to do this without additional hardware.

As Aaron Pointed out:

"Oh, do put your APs on nonoverlapping 2.4GHz channels (i.e. 1, 6 and 11.) "

you should use 3 non overlapping channels.

WDS is definitely a good thing, especially if doing EAP, especially especially if you can do CCKM for Fast Secure Roaming. But, if you're doing static WEP (as I infer the O.P. is), it doesn't really buy you anything.

Thank you all for your awnsers.

But what if I want to use WPA-PSK (AES or TKIP) and not WEP. Is that a problem?

Best Regards Martin

Usually not. There may be weird clients causing problems. It is really essential to avoid overlapping channels.
