I'm getting alot of these on multiple phones.

[Anonymous · Accepted solution]

This is normal to see in the output of a debug ip dhcp server when ADTRAN IP 706 or ADTRAN IP 712 phones are used. Despite the error message, the DHCP packets are processed by the NetVanta without issue.

Thanks,

Matt

Thank You!

Hi Support this error is coming up again on the phone system.  Customer is currently on version A4.03.00.SC.E.

Their Windows Domain Controller is currently their DHCP for vlan 1.  DHCP Server for VLAN 2 (voip) is the Adtran 7100.

Anyone have suggest.  I know the issue here is DHCP.

The phone says - waiting to initialize network, and goes into a loop.

You mentioned there is an external DHCP server for VLAN 1 in the picture.  Can you read these posts and make sure this issue is not happening where the external DHCP server is plugged into a trunk port?

Thanks,

Thanks Matt for that document.  That was the cause of the error.  Windows server dhcp server or default vlan.  Adtran 7100 was dhcp server for vlan 2 (VOIP). Thanks to Adtran Tech Support, we were able to resolve this issue.  He change the port for the server to be vlan 1 only.
