Chapter 4 Configuring Settings on the Cisco Unified IP Phone Network Configuration Menu Table 4-3 IPv4 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 or ITL file on the phone, you must unlock the file before you can save changes to the TFTP Server 1 option. In this case, the phone will delete the file when you save changes to the TFTP Server 1 option. A new CTL or ITL file will be downloaded from the new TFTP Server 1 address. 1. Unlock the CTL or ITL file if necessary (for example, if you are changing the administrative domain of the phone). If the CTL and ITL files both exist, unlock either file. 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. When the phone looks for its TFTP server, it gives precedence to manually assigned TFTP servers, regardless of the protocol. If your configuration includes both IPv6 and IPv4 TFTP servers, the phone prioritizes the order that it looks for its TFTP server by giving priority to manually assigned IPv6 TFTP servers and IPv4 TFTP servers. The phone looks for its TFTP server in the following order: 1. Any manually assigned IPv6 TFTP servers 2. Any manually assigned IPv4 TFTP servers 3. DHCPv6 assigned TFTP servers 4. DHCP assigned TFTP servers Note For information about the CTL and ITL files, refer to Cisco Unified Communications Manager Security Guide. For information about unlocking the CTL or ITL files, see Unlocking the CTL and ITL files, page 4-39.
