As of Analog and Digital Tenor Software Release P4-1-9, it is possible to have the Tenor receive a Dynamic IP address from a DHCP (Dynamic Host Configuration Protocol) Server. This is configurable from the console port at boot up, or using Telnet.
There are a few "caveats" (warnings) about using DHCP on the Tenor:
No other devices should register to this Tenor as a GateKeeper or Border Element.
When a new IP address is issued and received by the Tenor, all active calls will be lost.
You may have challenges configuring this Tenor via Telnet.
NETWORK INTERFACE PARAMETERS:
IP address on LAN is 192.168.55.3
IP address of default gateway to other networks is 192.168.55.1
HARDWARE PARAMETERS:
Serial channels will use a baud rate of 38400
After board is reset, start-up code will wait 3 seconds

To change any of this, press the <Enter> key within 3 seconds
(M)odify any of this or (C)ontinue? [M] m <type "m" here>
For each of the following questions, you can press <Return> to select the value shown in braces, or you can enter a new value.
NETWORK INTERFACE PARAMETERS:
Do you want a LAN interface? [Y] y <type "y" here>
Do you want to obtain an IP address automatically? [N] y <type "y" here>
Hostname? [nj_.3] <optional configuration>
Upon DHCP Configuration (or next boot up)
NETWORK INTERFACE PARAMETERS:
LAN IP address will be obtained from DHCP server
Host name is nj_.3
HARDWARE PARAMETERS:
Serial channels will use a baud rate of 38400
After board is reset, start-up code will wait 3 seconds

To change any of this, press the <Enter> key within 3 seconds
DHCP start
Received IPaddress(c0a82c0b) <Tenor's IP address in hex>
If the DHCP Server is not available…
After board is reset, start-up code will wait 3 seconds

To change any of this, press the <Enter> key within 3 seconds
DHCP start
No response from DHCP server. Please check!!
No response from DHCP server. Please check!!
etc.
At this point, you will either need to "power cycle" the Tenor, interrupt its boot up & assign it a Static IP Address, or wait until the DHCP Server finds this Tenor & assigns it an IP address.
config unit 1# print
Unit: 1
IP Address = 255.255.255.255 <means that this Tenor is a DHCP Client>
External IP Address = 0.0.0.0
Name = nj_.3
Online = 1
Relay ResetTime = 240
Relay Reset Number = 2
You can issue a Static IP Address from here, using the typical "ip" command from the Unit prompt. After submitting the change, the next time the Tenor is reset, it will have this new Static IP address.
