IPv6 TFTP Server 1
(SCCP phones
only)
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.
Note Before making 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. 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
or ITL file, see Unlocking the CTL and ITL files,
page 4-35.
1. Unlock the CTL or ITL file if necessary. If
both the CTL and ITL files exist, unlock either
of the files.
2. If DHCPv6 is enabled, set the 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.
4. Press the Valid a te softkey, and then press the
Save softkey.
