arp changes with jails

[Raymond Matos]

So when freenas creates a jail it also creates a network interface inside the jail and on the main os. It usually named something like epair01b and epair01a.

I have been getting alot of arp moved messages like the one below. It seems that when it creates the jail it setting its IP to the freenas IP, then freenas want to reclaim it hence the arp moved messages.

freenas ip (em0) 192.168.111.30
jail ip (epair2b) 192.168.111.31

Is this a bug? How can we fix.

Code:

Nov 12 21:59:21 fn9 kernel: arp: 192.168.111.30 moved from 02:c6:ff:00:0a:0a to 00:25:90:86:c2:02 on epair2b
Nov 12 21:59:21 fn9 kernel: arp: 192.168.111.30 moved from 02:17:eb:00:09:0a to 00:25:90:86:c2:02 on epair1b
Nov 12 21:59:21 fn9 kernel: arp: 192.168.111.30 moved from 02:08:c5:00:08:0a to 00:25:90:86:c2:02 on epair0b

Were you able to figure this out?

Nope. I am going to change out the switch, as i believe it might be related, but not 100% sure.
