14.3.3 Upload using TFTP

In addition to the direct console port connection, the Prestige supports the up/downloading of the firmware and the configuration file using TFTP (Trivial File Transfer Protocol) over LAN. Even though TFTP should work over WAN as well, it is not recommended because of the potential data corruption problem.

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

Step 1. Use telnet from your workstation to connect to the Prestige and log in. Because TFTP does not have any security check, the Prestige records the IP address of the telnet client and accepts TFTP requests only from this address.

Step 2. Put the SMT in command interpreter (CI) mode by entering 8 in Menu 24 – System Maintenance.

Step 3. Enter command “sys stdio 0” to disable SMT timeout, so the TFTP transfer will not be interrupted.
