Network Configuration Menu Chapter 4 Configuring Settings on the Cisco Unified IP Phone Table 4-2 Network Configuration Menu Options (continued) Option TFTP Server 1 Description To Change Primary Trivial File Transfer Protocol (TFTP) server used by the phone. If you are not using DHCP in your network and you want to change this server, you must use the TFTP Server 1 option. If you set the Alternate TFTP option to yes, you must enter a non-zero value for the TFTP Server 1 option. If neither the primary TFTP server nor the backup TFTP server is listed in the CTL file on the phone, you must unlock the CTL file before you can save changes to the TFTP Server 1 option. In this case, the phone will delete the CTL file when you save changes to the TFTP Server 1 option. 1. Unlock the CTL file, if necessary. 2. If DHCP is enabled, set the Alternate TFTP option to Yes. 3. Scroll to the TFTP Server 1 option, press the Edit softkey, and then enter a new TFTP server IP address. 4. Press the Validate softkey, and then press the Save softkey. For information about the CTL file, refer to Cisco Unified Communications Manager Security Guide. For information about unlocking the CTL file, see the "Security Configuration Menu" section on page 4-46. 4-10 Cisco Unified IP Phone 7970G/7971G-GE Administration Guide for Cisco Unified Communications Manager 6.1 OL-14626-01
