 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?

It *should* be normal behaviour.  The other devices on the Ethernet
shouldn't update their ARP listings until the box sends out some kind
of broadcast packet.  If it doesn't do so, the other devices will time
out their ARP mappings in 5 minutes.

Question abt arp in 5.1-RELEASE

2003-11-19 Thread Ilya V. Serov
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.

With respect and kind regards,
Ilya V. Serov, St-Petersburg, Russia.
