Primary Trivial File Transfer Protocol (TFTP)
server that the phone uses. If you are not using
DHCP in your network and you want to change
this server, you must use the TFTP Server 1 option.
If you set the Alternate TFTP option to yes, you
must enter a nonzero value for the TFTP Server 1
option.
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 1 option. In this
case, the phone deletes the file when you save
changes to the TFTP Server 1 option. A new CTL
or ITL file downloads from the new TFTP Server
1 address.
When the phone looks for the TFTP server, the
phone 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 the TFTP server by giving priority to manually
assigned IPv6 TFTP servers and IPv4 TFTP
servers. The phone looks for the TFTP server in
this order:
1
Any manually assigned IPv6 TFTP servers
2
Any manually assigned IPv4 TFTP servers
3
DHCPv6 assigned TFTP servers
4
DHCP assigned TFTP servers
For information about the CTL and ITL
files, see the

Communications Manager Security Guide
