Option Description
IPv6 TFTP Server 1 Primary IPv6 Trivial File Transfer Protocol
(SCCP phones (TFTP) server used by the phone. If you are not
only) 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
or ITL file on the phone.
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.
2.
3.
4.
For information about the CTL or ITL file, refer to
