Proxim and Cisco Access Point Interoperability?

Is anyone using Proxim Access Points with Cisco VLANs.... We're
interested in whether they are interoperable at the VLAN level....

 

I have used a cisco catalyst 500 series switch with VLAN's enabled on it (I used the smart ports settings on the cisco switch and have defined the port no 3(which i have connected the ethernet interface of access point) as an accesspoint and have connected the access point to it.The moment i have done this that port has become a trunk port.
Then i have assigned a vlan id on the access point and in order to make the changes get effective i have rebooted the access point .

I'm able to ping to the machine but i'm not able to get the configuration page both thro' the browser as well as the com port.

Then i have tried to analyse the issue what i did was i have connected only the access point and a laptop using a cat5 cross over cable and have run ethereal on it what i have observed is that the access point is sending stp updates.

I suspect some problem here did any one face with the same issue.
