Avaya Handsets Keep rebooting

Avaya Handsets Keep rebooting


I currently have a number of Avaya 9611G handsets that keep rebooting. This has started since setting up the IP Office system to work over VLANs. The handsets in question seem to not be able to communicate over the VLAN. We have a windows DHCP server using the 242 options as shown below


There isn't a pattern to the handsets that have this issue. We have two handsets sitting next to each other that are connected to the same switch. One works fine on the VLAN and the other is on a continuous reboot.

We have a temporary fix in place at the moment. If we clear the settings on the handset a number of times and then use a static IP address and VLAN then the handset eventually comes up on the correct VLAN. We have around 120 handsets and I'm worried that over time we might see this happening to more of them.

Thanks in advance

RE: Avaya Handsets Keep rebooting

Almost certainly a network issue & the handsets are not correctly getting the DHCP responses they require.
if your Data switches have been correctly configured then the option242 should not be needed as the handsets will locate the correct Vlan using lldp & obtain their information from the IP office LAN interface (provided that has DHCP enabled).

Do things on the cheap & it will cost you dear
