If you do not use DHCP in your network, then you must disable DHCP and manually enter the network configuration information. For more information, see "Interacting with the DHCP Server" section.

Use these guidelines when manually configuring the IP settings:

Ensure the TFTP server has an IP address.

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


Note When DHCP is enabled, you cannot configure IP settings, but you can configure and alternate TFTP server.

Changing the USB Configuration

Configuring the Security Certificate on the Phone

Security features establish and maintain authenticated communication streams between the phone and the Cisco Unified Communications Manager server, and digitally sign files before they are delivered.

A Locally Significant Certificate (LSC) installs on phones after you perform the necessary tasks that are associated with the Certificate Authority Proxy Function (CAPF). You can use Cisco Unified Communications Manager Administration to configure an LSC, as described in Cisco Unified Communications Manager Security Guide.

Alternatively, you can initiate the installation of an LSC from the Security Configuration menu on the phone. This menu also lets you update or remove an LSC.

Before you do so, make sure that the appropriate Cisco Unified Communications Manager and the CAPF security configurations are complete:

The CTL file should have a CAPF certificate.

The CAPF certificate must exist in the /usr/local/cm/.security/certs folder in every server in the cluster.

The CAPF is running and configured.

Refer to Cisco Unified Communications Manager Security Guide for more information. For more information about the security features, see the "Understanding Security Features for Cisco Unified IP Phones" section.

Depending on how you have configured the CAPF, this procedure installs an LSC, updates an existing LSC, or removes an existing LSC.

To configure an LSC on the phone, perform the following steps:

Procedure


Step 1 Obtain the CAPF authentication string that was set when the CAPF was configured.

Step 2 Choose SETTINGS > System Configuration > Security.

Step 3 Press * * # to unlock the option.

Step 4 Scroll to LSC and press the Update softkey.

The phone prompts for an authentication string.

Step 5 Enter the authentication string and press the Submit softkey.

The phone begins to install, update, or remove the LSC, depending on how the CAPF was configured. During the procedure, a series of messages appears in the LSC option field in the Security Configuration menu so that you can monitor progress. When the procedure completes successfully, the phone will display Installed or Not Installed.

The LSC install, update, or removal process can take a long time to complete. You can stop the process at any time by pressing the Stop softkey from the Security Configuration menu. (Settings must be unlocked before you can press this softkey.)

When the phone successfully completes the installation procedure, it displays "Success." If the phone displays, "Failed," the authorization string may be incorrect or the phone may not enabled for upgrading. Refer to error messages generated by the CAPF and take appropriate actions.

You can verify that an LSC is installed on the phone by choosing SETTINGS > System Configuration > Security. LSC displays Installed.

Changing the USB Configuration

When using the USB cable to configure a phone, you might need to change the USB configuration. The phone has a default USB IP address of 192.168.1.100 that you can use with the USB connection to the PC. If you need to change the USB port configuration, these options are available:

Obtain the IP address automatically, by getting an IP address from the PC with DHCP set up.

Use the IP address and subnet mask assigned in this area.

To view or configure the USB port configuration on a Cisco Unified Wireless IP Phone 7921G, follow these steps:

Procedure


Step 1 Choose SETTINGS > System Configuration > USB.

Step 2 To open the menu, press the Select button.

Step 3 Press * * # to unlock the menu.

Step 4 To configure DHCP, press Select button and choose one of these options:

To obtain an IP address automatically from the PC, choose Enable, then press Save. You have completed the USB configuration.

To use a static IP address, choose Disable, then press Save.


Note If you disabled DHCP, you must enter an IP address and a subnet mask by performing Step 5 through 12.

Do not perform the following steps if DHCP is enabled.


Step 5 To change the static IP address, scroll to IP Address, and press Select button.

Step 6 Enter a new IP address that is not assigned on the subnet.

Step 7 Press Options > Validate to verify the entry.

Step 8 To save the changes, press Save.

Step 9 To change the subnet for the new IP address, scroll to Subnet Mask and press Select button.

Step 10 Enter the appropriate subnet address.

Step 11 Press Options > Validate to verify the entry.
