Has anyone seen or heard of any issues with the 78xx phones and HP/3Com switches? (This is on 5500 & 4400 models)
We're seeing some weird issues whereby a 79xx or 69xx phone works fine on the HP switch, but in the same port a 78xx doesn't. Doing a WireShark, you see the 78xx phone DHCP & then continuously ARP the default router. After a while it repeats this DHCP/ARP cycle. It never gets any further in the boot process.
Thanks for the links, but I don't think they apply in this case. As I said, 79xx & 69xx phones are working fine, so the basic VLANs, LLDP-MED, etc are all setup correctly. There's something funky going on with the 78xx phones. (And I'm confident that it's not an OUI issue)
