Prestige 642R Series ADSL Router

To use TFTP, your workstation must have both Telnet and TFTP clients. To transfer the firmware and the configuration file, follow the procedure below:

Use Telnet from your workstation to connect to the Prestige and log in. Because TFTP does not have any security checks, the Prestige records the IP address of the telnet client and accepts TFTP requests only from this address.

Step 1. Put the SMT in command interpreter (CI) mode by entering 8 in Menu 24 – System Maintenance.

Step 2. Enter the command “sys stdio 0” (zero, not capital o) to disable the SMT timeout, so the TFTP transfer will not be interrupted. Enter the command “sys stdio 5” to restore the five- minute SMT timeout (default) when the file transfer is complete.

Step 3. Launch the TFTP client on your workstation and connect to the Prestige. Set the transfer mode to binary before starting data transfer.

Step 4. Use the TFTP client (see the example below) to transfer files between the Prestige and the workstation. The file name for the firmware is “ras” and for the configuration file, is “rom-0” (rom-zero, not capital o).

Note: If you upload the firmware to the Prestige, it will reboot automatically when the

file transfer is completed (the SYS LED will flash).

Note that the Telnet connection must be active and the SMT in CI mode before and during the TFTP transfer. For details on TFTP commands (see following example), please consult the documentation of your TFTP client program. For UNIX, use “get” to transfer from the Prestige to the workstation, “put” to do it the other way around, and “binary” to set binary transfer mode.

10.8.1 Example TFTP Command

The following is an example tftp command:

TFTP [-i] host put p312.bin ras

where “i” specifies binary image transfer mode (use this mode when transferring binary files), “host” is the Prestige IP address, “put” transfers the file source on the workstation (p312.bin – name of the firmware on the workstation) to the file destination on the remote host (ras - name of the firmware on the Prestige).

The following table describes some of the fields that you may see in third party TFTP clients.

Table 10-6		Third Party TFTP Clients - General fields
