Therefore, it is more suitable where complex interaction is notneeded between client and server.TFTP uses the UDP port 69 for data transmission. For TFTP basic operation, refer toRFC 1350.In TFTP, file transfer is initiated by the client.■ In a normal file downloading process, the client sends a read request to theTFTP server, receives data from the server, and then sends theacknowledgement to the server.■ In a normal file uploading process, the client sends a write request to the TFTPserver, sends data to the server, and receives the acknowledgement from theserver.TFTP transfers files in two modes:■ Binary for program files■ ASCII for text files.Implementation of TFTPn Only the TFTP client service is available with your device at present.Figure 300 TFTP configuration diagramSwitchTFTP ClientPCTFTP ServerIP network
