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 either of the files before
you can save changes to the TFTP Server 2 option.
In this case, the phone will delete either of the files
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
Note For information about the CTL or ITL file,
refer to Cisco Unified Communications
Manager Security Guide. For information
about unlocking the CTL and ITL files,
see to the 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. 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 Valida t 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.
