Phone lose VLan (manually set) during firmware upgrade


Phone lose VLan (manually set) during firmware upgrade

Performing firmware upgrade on Polycom vvx400 handset running to new firmware The phone fails to acquire network IP address and register after downloading the new application and when checked we found the vlan id was cleared. Note the vlan id is manually set. I see same issue was fixed a few firmware versions back in bug VOIP-100191. Could the issue still persist. Has any one seen this issue in newer firmware?

Re: Phone lose VLan (manually set) during firmware upgrade

Hello @jam,

welcome back to the Polycom Community.

I am not aware of any reports of this but most people do not set a VLAN address manually as there

are different ways to do this using LLDP, CDP or DHCP.


If this is affecting your organisation please open a support ticket.

In order to raise a support ticket you need to work with your Polycom reseller as they need to do this for you.


End Customers cannot usually open a ticket directly with Polycom support.

If this is some sort of an Internet discounter please post either your phone's MAC address or your Polycom devices serial so I can look up who would be able to support you. This may not be who you purchased the Polycom device from.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards
