Default PC's not receiving DHCP IP via data port on Avaya Phone

I have this problem on all computers using an Avaya phone data port to connect to the LAN since we replaced an Extreme switch with a new Cisco Meraki switch

The phones receive an IP OK (192.168.30.x)

The PC's don't get a data IP (10.50.20.x) but work if we assign them a static IP on this range, also the PC's do get a DHCP IP if plugged directly in to the switch.

We use an Avaya S8300 and G430 (Our DHCP server) onsite.

The Topology is:

PC (Avaya One-X) 10.50.20.x -- Switch -- Riverbed -- Firewall -- Avaya G430 (

We had to setup a Layer 3 relay on the switch to the DHCP server because PC's were not picking up a DHCP address before hand (when plugged in to the switch directly).

We have logged this with Avaya support who said it is a Switch port issue but we have tried all configs we can up to now.
