Setup new ip phones Adtran 7100 with Adtran 706 and 712 phone

[Anonymous]

I'm pulling my hair out trying to troubleshoot two phones are not booting up.  Actually I can't get any phone to boot up.

I have a few vlan on my network.

Vlan 1 - 192.168.150.254 (default)
Vlan 2 - 192.168.1.1 (testing)
Vlan 3 - 192.168.151.254 (guest)
Vlan 4 - 192.168.152.254 (VOIP).

When the phone boot up, I can see it attempts to go to VLANID = 4.  It stays there forever.

I have both vlan 1 and vlan 4 with option 157 that points to the 192.168.150.254 with the ftp user name and password.  I'm pretty sure this part is working as the phones does attempts VLAN 4.
I have dhcp set for vlan 4.

When I run show ip dhcp binding - I do not see any vlan 4 ip address though.

Any help is appreciate.

I think it's a dhcp server problem or an ftp server problem, but I'm not sure.  Does anyone knows what this message means?  I ran the command

DEBUG ip dhcp server

O.K. the problem here was that I have a second network switch which I stacked together and added vlan 4.  I can get an ip address from VLAN 4 now. 
However, the phone still does not boot.
On the phone itself, under status, I have this.  DHCP enabled.
Ip address 192.168.152.55 (vlan 4 which is correct)
subnet 255.255.255.0
Gateway 192.168.152.254

dns 209.18.47.61

dns 209.18.47.62

ftp:  NOT SET -------
tftp: 0.0.0.0
L2 Tagging: On
VLAN ID: 4

Here is the error I'm getting now when running debug ip dhcp server.  Any help is highly appreciated.

touristsis,

A problem we see fairly often is other DHCP servers being on the same VLAN as the phone.  Other network switches, firewalls, wireless routers, servers, etc can all potentially act as a DHCP server.  If the phone sees a response from more than one server it will typically prevent a phone from booting all the way, but could still work randomly when it is rebooted.  I know you mentioned in your earlier post that you had another stacked switch in the mix and resolved that.  I would suggest that you check these things next:

• Audit all your existing network equipment to make sure there are no other DHCP servers that can be conflicting.  You can use Wireshark to do a packet capture and see if any DHCP offers are coming from something other than the 7100.

• Check to make sure your DHCP, switchport, and VLAN configurations are correct.  Feel free to attach your configuration to this thread but be careful to remove any sensitive information first (usernames/passwords, public IPs, public phone numbers, etc).

• Try plugging the phone directly in the 7100 on a trunk port.  If the phone completes the boot process there is likely a network infrastructure issue somewhere between the 7100 and where the phone plugs in (includes all the switches in-between).  If it does not work plugged in directly to a trunk port, try hard setting that port for VLAN 4.  If that works, there is likely a DHCP configuration issue on the 7100.

I hope some of this helps.  Feel free to reply with any further information or questions and I would be happy to help.

Thanks,
Matt

Hi Matt,

I've found the problem.  On option 157.

I had FtpServer=192.168.152.254

It needed to be FtpServers=192.168.152.254

That's right, the plural make the difference...
