Chapter 4 Configuring Settings on the Cisco Unified IP Phone
Network Configuration Menu
TFTP Server 1 Primary 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 or ITL file on the
phone, you must unlock the file before you can
save changes to the TFTP Server 1 option. In this
case, the phone will delete the file when you save
changes to the TFTP Server 1 option. A new CTL
or ITL 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
For information about the CTL file, see Cisco
Unified Communications Manager Security
Guide. For information about unlocking the CTL
file, see Security Configuration Menu, page 4-35.
1. Unlock the CTL or ITL file if necessary (for
example, if you are changing the
administrative domain of the phone). If the
CTL and ITL files both exist, unlock
either file.
2. If DHCP is enabled, set the Alternate TFTP
option to Ye s.
3. Scroll to the TFTP Server 1 option, press the
Edit softkey, and then enter a new TFTP
server IP address.
4. Press the Validate softkey, and then press the
Save softkey.
Note If you forgot to unlock the CTL file, you
can change the TFTP Server 1 address in
the CTL file, then erase the CTL file by
pressing the Erase softkey from the
Security Configuration menu. A new CTL
file will be downloaded from the new TFTP
Server 1 address.
