Cisco Unified IP Phone after you install the phone on the network:

• IP address

• IP subnet information (subnet mask for IPv4 and subnet prefix length for IPv6)

• Default gateway IP address

• TFTP server IP address

You may also configure these optional settings as necessary:

• Domain name

• DNS server IP address

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 Cisco Unified Communications Manager Security Guide.

You can initiate the installation of a Locally Significant Certificate (LSC) from the Security Configuration

menu on the phone. This menu also lets you update or remove an LSC.

are complete:

• On Cisco Unified Communications Operating System Administration, verify that the CAPF certificate
