Chapter 4 Configuring Settings on the Cisco Unified IP Phone
Network Configuration Menu
TFTP Server 2 Optional backup TFTP server that the phone uses
if the primary TFTP server is unavailable.
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 2 option. In this
case, the phone will delete the file when you save
changes to the TFTP Server 2 option. A new CTL
or ITL file will be downloaded from the new TFTP
Server 2 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. Manually assigned IPv6 TFTP Servers
2. Manually assigned IPv4 TFTP Servers
3. DHCPv6 assigned TFTP Servers
4. DHCP assigned TFTP Servers
For information about CTL and ITL files, see the
Cisco Unified Communications Manager Security
Guide. For information about unlocking CTL and
ITL files, see to 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. Unlock network configuration options.
3. Enter an IP address for the TFTP Server 1
option.
4. Scroll to the TFTP Server 2 option, press the
Edit softkey, and then enter a new backup
TFTP server IP address.
5. 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 2 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 2 address.
BOOTP Server Indicates whether the phone obtains its
configuration from a Bootstrap Protocol (BootP)
server instead of from a DHCP server.
Display only—Cannot configure.
