Configuring Startup Network Settings
Configuring Startup Network Settings
If you are not using DHCP in your network, you must configure these network settings on the 
Cisco
 Unified IP Phone after installing the phone on the network:
  • IP address
  • IP subnet mask
  • Default gateway IP address
  • TFTP server IP address
You may also configure these optional settings as necessary:
  • Domain name
  • DNS server IP address
Collect this information and see the instructions in Chapter 4, “Configuring Settings on the Cisco 
Unified IP Phone.”
Configuring Security on the Cisco Unified IP Phone
The security features protect against several threats, including threats to the identity of the phone and to 
data. These 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.
For more information about the security features, see the “Understanding Security Features for Cisco 
Unified IP Phones” section on page 1-9. Also, refer to Cisco Unified Communications Manager Security 
Guide.
A Locally Significant Certificate (LSC) installs on phones after you perform the necessary tasks that are 
associated with the 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 begin, make sure that the appropriate Cisco Unified Communications Manager and the 
Certificate Authority Proxy Function (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.
To configure an LSC on the phone, perform the following procedure. Depending on how you have 
configured the CAPF, this procedure installs an LSC, updates an existing LSC, or removes an existing 
LSC. 
Procedure
Step 1 Obtain the CAPF authentication code that was set when the CAPF was configured.
Step 2 From the phone, press the Settings > Security Configuration.
