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 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
Note For information about the CTL and ITL
files, refer to Cisco Unified
Communications Manager Security
Guide. For information about unlocking
the CTL or ITL files, see Unlocking the
CTL and ITL files, page 4-39.
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 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 Valida t e softkey, and then press the
Save softkey.
