DHCP and TFTP

Dynamic Host Configuration Protocol (DHCP) provides a means by which configuration
parameters can be automatically assigned to clients on a TCP/IP network. This minimizes the
maintenance of a 4600 Series IP Telephone network by removing the need to individually assign
and maintain IP addresses and other parameters for each IP telephone on the network.

Software Checklist

Please make sure that you have purchased and/or own licenses to install and use the DHCP
server and TFTP server software.
It is possible to install both the DHCP server and the TFTP server on the same machine.
WARNING:
The circuitry in the 4600 Series IP Telephones reserves IP addresses of the form
192.168.2.x for internal communications. The telephone(s) will not properly use addresses
you specify if they are of that form.

Required Network Information

DHCP is the control point where an enterprise controls its IP Telephones. Before administering
DHCP and TFTP, complete the information in
have the necessary information regarding your network. There may be more than one Gateway,
TFTP server, subnet mask and CLAN in your configuration. You will need a copy of this table for
each DHCP server.
Release 1.5 of the 4600 Series Telephones supported the ability to specify a list of IP addresses
for a gateway/router, TFTP server, and Avaya media server CLAN board(s), as explained in
Overview of Voice over IP (VoIP), on page
characters, with IP addresses separated by commas with no intervening spaces.
When specifying IP addresses for the TFTP server or call server, you can use either dotted
decimal format ("xxx.xxx.xxx.xxx") or DNS names to identify the address(es). If you use DNS, note
that the system value DOMAIN will be appended to the IP addresses you specify. If DOMAIN is
null, the DNS names must be fully qualified, in accordance with IETF RFCs 1034 and 1035. For
more specific information about DNS, see
Addressing, on page
2-1. Each list may contain up to 127 total ASCII
