How to upgrade firmware for RGOS11.X with TFTP?

Run the "show version detail" command to display the current version, that is, system software number.

Verify the upgrade file used by checking Release Notes.
I. Configuration Steps

• Start the TFTP server on the PC and specify the directory of the upgrade file. Ensure that the PC communicates properly with the S86E.
• The S86E serves as the TFTP client. The upgrade method is the same as that in the common TFTP upgrade mode. Copy the upgrade file to the USB flash drive on the CMI, or to the built-in Flash on the CMII.

II. Note

• The only difference between the TFTP and USB onsite upgrade modes lies in the file transfer mode. In TFTP upgrade mode, the upgrade file is transferred to the remote device through TFTP to meet the remote upgrade requirement. In USB onsite upgrade mode, the upgrade file is directly copied from a PC to the USB flash drive.
• The subsequent upgrade method is the same. That is, run the upgrade command to update the file and then restart the device to finish the upgrade.
• The TFTP transmission rate is lower than the FTP transmission rate. Data is transmitted using TCP in FTP mode and using UDP in TFTP mode. TFTP is simple and easy to use.
