Understanding the Phone Startup Process Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network Table 2-4 Task 3. 4. 5. 6. Cisco Unified IP Phone Startup Process (continued) Purpose Related Topics Configuring VLAN. If the Cisco Unified IP Phone is connected to a Cisco switch, the switch next informs the phone of the voice VLAN defined on the switch port. The phone needs to know its VLAN membership before it can proceed with the Dynamic Host Configuration Protocol (DHCP) request for an IP address. See the "Network Configuration Menu" section on page 4-5. See the "Resolving Startup Problems" section on page 9-1. 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. See the "Network Configuration Menu" section on page 4-5. See the "Resolving Startup Problems" section on page 9-1. Accessing a TFTP Server. on 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 configure the TFTP server locally on the phone; the phone then contacts the TFTP server directly. See the "Network Configuration Menu" section on page 4-5. See the "Resolving Startup Problems" section on page 9-1. Note You can also assign an alternative TFTP server to use instead of the one assigned by DHCP. Requesting the CTL file. The TFTP server stores the certificate trust list (CTL) file. This file contains a list of Cisco Unified Communications Managers and TFTP servers that the phone is authorized to connect to. It also contains the certificates necessary for establishing a secure connection between the phone and Cisco Unified Communications Manager.

Chapter 2
Preparing to Install the Cisco Unified IP Phone on Your Network
Understanding the Phone Startup Process
3.
Configuring VLAN.
If the Cisco Unified IP Phone is connected to a Cisco
switch, the switch next informs the phone of the voice
VLAN defined on the switch port. The phone needs to
know its VLAN membership before it can proceed with the
Dynamic Host Configuration Protocol (DHCP) request for
an IP address.
See the
“Network Configuration Menu” section
on page 4-5
.
See the
“Resolving Startup Problems” section on
page 9-1
.
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.
See the
“Network Configuration Menu” section
on page 4-5
.
See the
“Resolving Startup Problems” section on
page 9-1
.
5.
Accessing a TFTP Server.
on 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 configure 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.
See the
“Network Configuration Menu” section
on page 4-5
.
See the
“Resolving Startup Problems” section on
page 9-1
.
6.
Requesting the CTL file.
The TFTP server stores the certificate trust list (CTL) file.
This file contains a list of Cisco Unified Communications
Managers and TFTP servers that the phone is authorized to
connect to. It also contains the certificates necessary for
establishing a secure connection between the phone and
Cisco Unified Communications Manager.
Refer to
Cisco Unified Communications Manager
Security Guide,
“Configuring the Cisco CTL
Client” chapter.
