ARP Poisoning?

I have a 5300 I'm using as a core for our network. We are installing 30mbit pipes between sites (13) to replace our T1's. I have our LAN on 172.16.x.x and the Broadcast for the up links on 10.0.0.x. The problem I am encountering is whenever I bring these circuits up they are very intermittent. But when I clear the arp cache on the core they come right up only to drop again about 30 seconds later.

Re: ARP Poisoning?

Could be ARP poisoning as you've suggested.

E.10.62 does contain an ARP related fix - you'll need to call ProCurve support to get your hands on this.
