4500 and remembers IP


i'm using switches 4500 (stacked), with dot1x included and freeradius and dhcp serwer exluded (on different hardware). I set guest-vlan for dot1x, where user have access only to one page (inform that authorization is needed). And now, after authorization user have new IP from DHCP (another subnet) and full access to network, but switch remember IP before authorization (see in 'display connections').

This is bad, i can't logging valid IP through 3Com->freeradius->SQL.

It's bug or i should (dis-|en-)able any switch's function to refreshing IP?
