Option
IPv6 TFTP Server 1
(SCCP phones only)
OL-21011-01
Description
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.
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:
Manually assigned IPv6 TFTP Servers
1.
Manually assigned IPv4 TFTP Servers
2.
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
