We have PC's connected through some phones.
what is the data vlan number?
I resoved this. The issue was the 157 option. On the server the option already exist by default, and only allows you to put in the ftp sever name and or ip address. You must, under server options for the server, remove the default 157 option (because you cannot create a cusom option with the same ID). Then create a custom option with the 157 ID with a string value
TftpServers=0.0.0.0,FtpServers=(the ip of the dhcp on the adtran for the vlan your phones are on [as you can see mine are on vlan 20]):/ADTRAN,FtpLogin=polycomftp,FtpPassword=password,Layer2Tagging=True,VlanID=20
Tested this, this morning and all is good. Factory reset the phone and it finds the domain controller/dhcp server on the .180 vlan, the executes the option and resolves the ftp server address and re configures the phone to the proper vlan and downloads all of the config files.
good job Kerry!
Thanks for posting your solution!
Yes that DHCP Windows Options config guide tells you that you must create a custom option.
Let us know if you have any other problems.
