Configuring Network Settings on the Cisco IP Phone

Because the Cisco IP Phone is a network device, it includes many configurable network settings, which you might need to modify before the phone is accessible and functional for your users.

The following sections provide details about configuring and verifying these network settings:

•Configuring Methods

•Verifying Network Settings

•Modifying DHCP Settings

•Configuring IP Settings

•Modifying VLAN Settings

•Configuring TFTP Options

•Configuring CDP

Configuring Methods

On the Cisco IP Phone 7902G, you can configure network settings using the phone's web page or using its Interactive Voice Response (IVR) system. On the Cisco IP Phone models 7905G/7912G, you can configure network settings through the phone's web page or using the Network Configuration screen on the phone.

This chapter describes various methods you can use to configure most network settings for the Cisco IP Phone. For more information about web page configuration, and for information about IVR system configuration, see "Additional Configuration Methods, Parameters, and Procedures."

Accessing Network Configuration Settings from a Cisco IP Phone

On the Cisco IP Phone models 7905G/7912G, network configuration options in the Network Configuration Screen are locked by default to prevent users from making changes that could affect network connectivity for a phone.

When settings are inaccessible for modification, a locked padlock icon appears on the Network Configuration screen. An unlocked padlock icon appears on this screen when settings are unlocked and accessible for modification.

You must unlock the network configuration options from the Network Configuration screen before you can configure them. If a password has been specified for the phone, you must enter the password when unlocking network configuration options. (For more information about passwords, see "Additional Configuration Methods, Parameters, and Procedures.")

Network configuration options are locked again automatically when you exit the Network Configuration Screen.

The unlocked padlock icon, shown below, appears in the margins of this chapter to indicate procedures that require you to unlock settings before modifying them.

Note On the Cisco IP Phone 7902G, network settings are not locked on the phone itself because these settings are accessed through the Phone Configuration web page or the Interactive Voice Response (IVR) system. See the specific instructions for the Cisco IP Phone 7902G in the sections that follow for more information.

To unlock network settings on the Cisco IP Phone models 7905G/7912G, follow these steps.

Procedure

Step 1 Press the Menu button.

Step 2 Use the Navigation button to select Settings, and then press the Select softkey.

Step 3 Use the Navigation button to select Network Configuration, and then press the Select softkey.

Step 4 From the Network Configuration menu, press **#.

Step 5 If your phone displays "Enter Admin Password," enter your password and then press the Enter softkey.

Step 6 Look at the upper-right portion of your LCD.

•Locked—The icon appears as a locked padlock.

•Unlocked—The icon appears as an unlocked padlock.

Accessing Network Configuration Settings through a Phone's Web Page

The following sections include instructions for setting configuration options using a phone's web page. To set configuration options in this way, you must first use the UIPassword parameter in the phone's profile file to set up a password. If you do not set up a password, you will not be able to change network settings, and Apply will not be available.

For more information about the UIPassword parameter, see Table A-4.

Verifying Network Settings

Configuring IP Settings

Use these guidelines when manually configuring the IP settings:

•You can use 0.0.0.0 for the subnet mask only if the default gateway is also 0.0.0.0.

•Ensure the TFTP server has an IP address.

•Ensure the default gateway IP address is on the same subnet as the host IP address.

Note Procedures involved in configuring IP settings or TFTP options cannot be completed when DHCP is enabled in your network.

This section covers the following topics:

•Assigning a Default Router

•Assigning a Subnet Mask

•Assigning a Domain Name

•Assigning DNS Servers

Assigning an IP Address

The IP address is the unique logical address identifying each host computer, or node, on a TCP/IP network. An IP address is a 32-bit number expressed as four decimal numbers from 0 to 255 separated by periods.

Before you can assign an IP address, you must disable DHCP. For instructions, see the "Disabling DHCP" section.

Using the Phone Configuration Web Page (Cisco IP Phone Models 7902G/7905G/7912G)

Procedure

Step 1 Open the Phone Configuration web page.

a. Open your web browser and enter the following URL, where IPaddress is the IP address of your phone:
