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 prece-
dence 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, see
Cisco Unified Communications Manager Security
Guide.
1. Unlock the CTL or ITL file if
necessary (for example, if you
are changing the administrative
domain of the phone). If both the
CTL and ITL files exist, unlock
either of the files.
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 Select softkey,
and then enter a new backup
TFTP server IP address. If there
is no secondary TFTP Server,
you can use the Delete softkey to
clear the field of a previous
value.
5. Press the Apply softkey and then
press Save.
If you forgot to unlock the CTL or
ITL file, you can change the TFTP
Server 2 address in either file, then
erase them by pressing the Erase
softkey from the Security
Configuration menu. A new CTL or
ITL file will be downloaded from the
new TFTP Server 2 address.
BOOTP Server Indicates whether the phone received its IP address from a
BOOTP server rather than from a DHCP server.
Display-only field.
DHCP Address
Released
Releases the IP address assigned by DHCP. This field is editable if DHCP is
enabled. If you wish to remove the
phone from the VLAN and release
the IP address for reassignment, set
this option to “Yes” and press the
Apply softkey.
