7.3. Upgrading Software Using Ethernet

TFTP (Trivial File Transfer Protocol) is simple file transfer protocol that is used without complex interaction

between clients and servers.

TFTP is normally implemented based on UDP.

The client initiates a TFTP transmission. To download files, the client sends a read request packet to the TFTP

server, receives the packet from the server, and sends the acknowledgement to the server. To upload files, the client

sends a write request packet to the TFTP server, sends the data packet to the server, and receives the

acknowledgement from the server. There are two modes of TFTP transmission files: the binary mode used for

transmitting program files and ASCII mode used for transmitting text files.

Switch 7700 provides the functions of the TFTP client.

Note:

The Switch 7700 is not shipped with the TFTP Server program.

To upgrade using TFTP:

1. Connect the switch to the PC from which the file is downloaded, using the 10BASE-T/100BASE-TX

port on the Fabric for upgrading. The IP address of the PC is required. At the same time, the switch is

externally connected to a PC (which can be the same PC as that the downloaded file is located) using a

console port.
