Network Configuration Menu
TFTP Server 2 Optional backup TFTP server that the phone with an IPv4
address 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 files 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 file 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
Note For information about the CTL and ITL files, see
Cisco Unified Communications Manager Security
Guide. For information about unlocking CTL and
ITL files, see
Unlocking the CTL and ITL Files,
page 4-41
1. Unlock the CTL or ITL files 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 Validat e 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.
