Description
Option
Set TFTP Server 2 Field, on page 81
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 deletes
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
For information about the CTL or ITL
file, see the
Cisco Unified
Communications Manager Security
Guide

unlocking the CTL and ITL files, see
