3. Configuring VLAN If the Cisco Unified IP Phone is connected to a
Cisco Catalyst switch, the switch next informs
the phone of the voice VLAN defined on the
switch. The phone needs to know its VLAN
membership before it can proceed with the
Dynamic Host Configuration Protocol (DHCP)
request for an IP address.

4. Obtaining an IP
Address
If the Cisco Unified IP Phone is using DHCP to
obtain an IP address, the phone queries the
DHCP server to obtain one. If you are not using
DHCP in your network, you must assign static
IP addresses to each phone locally.

5. Accessing a TFTP
Server
In addition to assigning an IP address, the
DHCP server directs the
Cisco Unified IP Phone to a TFTP Server. If the
phone has a statically-defined IP address, you
must enter information about the TFTP server
locally on the phone; the phone then contacts the
TFTP server directly.
Note
You can also assign an alternative TFTP
server to use instead of the one assigned
by DHCP.

6. Requesting the
Configuration File
The TFTP server has configuration files, which
define parameters for connecting to Cisco
Unified Communications Manager and other in-
formation for the phone.
