RFC for Roaming?

[Sven Hruza]

Hi,

I have some issues with a wireless end device and wlan roaming.

There are 5 different wireless clients where the roaming works great, but with one Windows Mobile 6.5 devices I have some trouble.

The device uses a static IP-address.

I created a mirror port and some other tests and found that the MAC of the wireless client stays on the switchport of the first accesspoint and is not on the switchport of the second accesspoint to which the client roamed.

It seems that the client don't send a arp reply or something like that to tell the world that it is now on another accesspoint.

With DHCP on the wireless client we don't have that issue because the client starts a DHCP request together with every roaming.

For completeness I have to say that the wireless infrastructure is not Cisco.

But I had the hope, that somebody here in the community has some experiences with such issues or can tell how a roaming has to work.

Is it the doing of the client to tell "where it is" or should the wireless infrastructure propagate that?

Thanks a lot!

Sven

Sven,

What wireless equipment are you using ?

To reply on your general enquiry, the client when it associates to the new AP can (not mandatory) mention the old AP radio mac address.

It's up to the new AP to advertise the old AP that the client has moved. This is apparently not happening.

There is no standard protocol for that and Cisco does IAPP but I have no idea what other brands are doing.
