Chapter 4 Configuring Settings on the Cisco Unified IP Phone Network Configuration Menu Table 4-4 IPv6 Configuration Menu Options (continued) Option IPv6 TFTP Server 1 (SCCP phones only) Description To Change Primary IPv6 Trivial File Transfer Protocol (TFTP) server used by the phone. If you are not using DHCPv6 in your network and you want to change this server, you must use the IPv6 TFTP Server 1 option. If you set the IPv6 Alternate TFTP option to Yes or you disable DHCPv6, you must enter a non-zero value for the IPv6 TFTP Server 1 option. If you make changes to the Alternate TFTP or IPv6 TFTP servers, you must first unlock the CTL file or ITL file on the phone. 1. Unlock the CTL file or ITL file, if necessary. If the CTL and ITL files both exist, unlock either file. 2. If DHCPv6 is enabled, set the IPv6 Alternate TFTP option to Yes. 3. Scroll to the IPv6 TFTP Server 1 option, press the Edit softkey, and then enter a new TFTP server IP 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: 4. Press the Validate softkey, and then press the Save softkey. 1. Manually assigned IPv6 TFTP Servers 2. Manually assigned IPv4 TFTP Servers 3. DHCPv6 assigned TFTP Servers 4. DHCP assigned TFTP Servers For information about the CTL or ITL file, refer to Cisco Unified Communications Manager Security Guide. For information about unlocking the CTL file, see Unlocking the CTL and ITL Files, page 4-40.
