Description
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 On, 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
IPv4 TFTP servers
2. Any manually assigned
IPv6 servers
3. DHCP assigned TFTP
servers
4. DHCPv6 assigned TFTP
servers
