Some Avaya 9608 handsets work, others don't - FIXED
We're looking to roll out Avaya 9608 handsets to a site that currently do not use IPT.
Another team look after the Avaya side of things. I'm on the LAN/WAN side. Site have one large data VLAN but we need several smaller voice VLANs for each building so rather than using DHCP option 242 in the data VLAN to inform the handsets of the voice VLAN, we are using LLDP.
The switches are mostly 3560s and 3750s running 12.2(44)SE6 IPBASE. We are currently testing using a single port/cable.
The issue we have is that some phones (brand new out of the box) pick up the voice VLAN, get an IP, register to the call manager and work perfectly while others don't.
I'm completely stumped as to why they don't work??? There are plenty of spare IPs in the DHCP pools for the data and voice VLANs. There is no port security so we not hitting an MAC limit.
The bad phones correctly pick up the voice VLAN and DHCP discover out but don't appear to get a response. You'd think this was a fault with the DHCP server but why do some phones work and others not?? Helper addresses on the SVI are good. The DHCP servers are offsite but work fine for all other VLANs. Remember - some phones work in this very same port, whilst other do not.
We've not implemented IPT using LLDP before (usually just use DHCP option 242 in data VLAN) so folks are starting to point their fingers at this but I'm not convinced - especially as the phone appears to pick up the correct voice vlan.

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
1) Login into the CLI of the Publisher.
