Question abt arp in 5.1-RELEASE

Hello dear all.

    I've got a curious thing with FBS 5.1-RELEASE, concerning arp 
requests/reply. I have a LAN, connected to Internet through CISCO 
router. Recently I had to move one ip address inside my LAN from a 4.8 
box to a 5.1 box without a reboot (ifconfig ...). After this I had 
discovered that CISCO continue sending packets to old MAC address (to 
4.8). After an investigation of the problem I discovered, thet CISCO had 
not "forgotten" the old MAC. If  ip is being moved from 4.8 box to 4.8 
box this effect fanishes.
    Did anyone get similar problems? Is it a feature or a bug in 5.1, or 
I don't understand something?

				Great thanks in advance for any support.
