Network Configuration Menu Chapter 4 Configuring Settings on the Cisco Unified IP Phone Table 4-3 IPv4 Configuration Menu Options (continued) Option TFTP Server 2 BOOTP Server Description To Change Optional backup TFTP server that the phone with an IPv4 address uses if the primary TFTP server is unavailable. If neither the primary TFTP server nor the backup TFTP server is listed in the CTL or ITL files on the phone, you must unlock the file before you can save changes to the TFTP Server 2 option. In this case, the phone will delete the file when you save changes to the TFTP Server 2 option. A new CTL file or ITL file will be downloaded from the new TFTP Server 2 address. 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. Manually assigned IPv6 TFTP servers 2. 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 CTL and ITL files, see Unlocking the CTL and ITL Files, page 4-40 1. Unlock the CTL or ITL files 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. Unlock network configuration options. 3. Enter an IP address for the TFTP Server 1 option. 4. Scroll to the TFTP Server 2 option, press the Edit softkey, and then enter a new backup TFTP server IP address. 5. Press the Validate softkey, and then press the Save softkey. Note If you forgot to unlock the CTL file, you can change the TFTP Server 2 address in the CTL file, then erase the CTL file by pressing the Erase softkey from the Security Configuration menu. A new CTL file will be downloaded from the new TFTP Server 2 address. Indicates whether the phone obtains its configuration from Display only-Cannot configure. a Bootstrap Protocol (BootP) server instead of from a DHCP server. 4-12 Cisco Unified IP Phone Administration Guide for Cisco Unified Communications Manager 8.0 (SCCP and SIP) OL-21011-01
