Upgrading the Software Trivial File Transfer Protocol (TFTP) transmissions are initiated by the client. When Using TFTP 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 sends a write request packet to the TFTP server, then sends the data packets to the server, and receives the ACK from the server. The TFTP transmission files have two forms; binary for program transmission and ASCII for text transmission.
To upgrade the software using TFTP perform the following steps.
n This procedure uses a Switch 8814 work as the TFTP client.
1Connect the switch to a PC where the file is located using the management/upgrade Ethernet port. (You need the IP address of the PC. At the same time, connect the switch to an external PC (that can be the same one that contains the file) using the console port.
2Run the TFTP server program on the PC connected to the management/upgrade Ethernet port and specify the path for upgrading the application files.
3Run the terminal emulation program on the PC connected to the console port, and boot the switch to access the Boot menu.
