WLAN Client roaming over different switches

[s.ferro]

Hi all,

I have problems with the roaming and connectivity of WLAN Clients:

There are 2 Cisco Inline power switches (3524) with access points (AP350). The 3524 switches are connected through their gigabit interfaces to a 6509 Catalyst. When a WLAN Client roams from the access point on the first 3524 switch to an access point on the other 3524 it looses the IP connectivity to the network (locally fron the AP I can ping the client).

I found out that if I clear the arp-cache on the 6509 the connectivity gets restored after a few seconds.

Now my question: Is there a possibitlity to reduce the connectivity loss to 0 sec. without changing the network design?

Thanks for your help!!!

No..i don't think so..However the foorts are going on to reduce the loss of connectivity time to minimum.
