Dhcp Server Administration; Configuring Dhcp For 1603Sw-I Sip Ip Deskphones - Avaya one-X 1603SW Administrator's Manual

Server Administration

Important:
An IP deskphone cannot function without an IP address. The failure of a DHCP
Important:
server at boot time leaves all the affected deskphones unusable. A user can
manually assign an IP address to an IP deskphone. When the DHCP server
finally returns, the deskphone never looks for a DHCP server unless the static IP
data is unassigned manually. In addition, manual entry of IP data is an
error-prone process.
Avaya recommends that:
A minimum of two DHCP servers be available for reliability.
●
A DHCP server be available when the IP deskphone reboots.
●
A DHCP server be available at remote sites if WAN failures isolate IP deskphones from the
●
central site DHCP server(s).
A (HTTP or HTTPS) file server, which may run on the same physical computer as Avaya Aura
Communication Manager, provides the 1603SW-I SIP IP Deskphone with a 16xxupgrade.txt file
and, if appropriate, new or updated binary software. See
page 18. In addition, you can edit the settings file (46xxupgrade.txt) to customize deskphone
parameters for your specific environment. For more information, see

Configuring DHCP for 1603SW-I SIP IP Deskphones

1603SW-I SIP IP Deskphones allow you to specify the value of some configuration parameters
using DHCP option 242. If you have 46xx phones that use option 176, you can make a copy of
an existing option 176. Then, using that copy to administer DHCP option 242, you can either:
leave any (46xx) parameters the 1603SW-I SIP IP Deskphones do not support in Option
●
242 to be ignored, or
delete unused or unsupported 1603SW-I SIP IP Deskphone parameters to shorten the
●
DHCP message length.
