Nortel Secure Network Access Switch 4050 User Guide

 

The DHCP server and the IP Phone 2002, IP Phone 2004, and IP Phone 2007 can 
be configured so that the IP Phone automatically obtains its configuration data 
from the DHCP server. This feature reduces the administrative overhead 
associated with bringing a large number of IP Phones online.

In addition, the DHCP server and the IP Phone can be configured so that the 
IP Phone can use the Auto VLAN Discovery feature, which allows the IP Phone 
to discover the Phone VLAN ID.

This appendix explains how to: 

•

configure the IP Phone to obtain its configuration data from a Windows 2000 
Server DHCP server

•

retrieve VLAN information required to take advantage of the Auto VLAN 
Discovery feature

This appendix is not intended to be a primer on how to set up a DHCP server. The 
reader is assumed to have a working knowledge of Windows 2000 Server DHCP 
servers. The appendix also does not describe the process used by the IP Phone to 
interact with the DHCP server or to boot itself into the Phone VLAN.

To take advantage of the Auto VLAN Discovery feature, two VLANs are 
required: one for the phone to boot into initially, in order to communicate with the 
DHCP server and learn the appropriate phone VLAN ID, and the second for the 
Phone VLAN itself.

Note: It is assumed that the necessary DHCP scopes defining the range 
of addresses and lease duration have been created.
