Chapter 4 Configuring Settings on the Cisco Unified IP Phone
Network Configuration Menu
TFTP Server 1 Primary Trivial File Transfer Protocol (TFTP) server used
by the phone. If you are not using DHCP in your network
and you want to change this server, you must use the TFTP
Server 1 option.
If you set the Alternate TFTP option to Yes, you must enter
a non-zero value for the TFTP Server 1 option.
If neither the primary TFTP server nor the backup TFTP
server is listed in the CTL file on the phone, you must
unlock the CTL file before you can save changes to the
TFTP Server 1 option. In this case, the phone will delete
the CTL file when you save changes to the TFTP Server 1
option. A new CTL file will be downloaded from the new
TFTP Server 1 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. Any manually assigned IPv6 TFTP servers
2. Any manually assigned IPv4 TFTP servers
3. DHCPv6 assigned TFTP servers
4. DHCP assigned TFTP servers
Note For information about the CTL file, refer to Cisco
Unified Communications Manager Security Guide.
For information about unlocking the CTL file, see
the “Security Configuration Menu” section on
page 4-37.
1. Unlock the CTL file if necessary
(for example, if you are changing
the administrative domain of the
phone).
2. If DHCP is enabled, set the
Alternate TFTP option to Yes .
3. Scroll to the TFTP Server 1
option, press the Edit softkey,
and then enter a new TFTP
server IP address.
4. Press the Valid ate softkey, and
then press the Save softkey.
