We have upgraded our COS v5 to V7.3 and now our Avaya handsets are not getting the correct address from the ClearOS.

There are four physical interfaces, External, LAN, Corporate WAN and Visitor. - IP Settings.PNG

The LAN interface is set up for three VLANs with no IP address on the physical interface.

VLAN 100 - LAN
VLAN 102 - Second LAN
VLAN 200 - VOIP


DHCP is enabled on two of the VLANs and also the Visitor interface. - DHCP-Settings.PNG

A handset plugged into port 5 on the switch is being served an address from the Visitor LAN.

Excerpt from Switch Config file:

interface gigabitethernet1/5

 switchport trunk allowed vlan add 200 

 switchport trunk native vlan 900 

Relevant bit of DHCP.conf

At the moment we are manually setting the IP address for each handset.
