Upgrading software through management Ethernet port (TFTP)

1Introduction to TFTP

Trivial file transfer protocol (TFTP) is well suited to the file transfer between a server and a client that do not need complex interaction.

In TFTP, the transmission is initiated by the client. When downloading a file, the client sends a read request packet to the TFTP server, receives the data packets from the server, and sends the ACK to the server. When uploading a file, the client
