Upgrading applications through the management Ethernet

interface

The Trivial File Transfer Protocol (TFTP) is a TCP/IP protocol used for file transfer between client and server.

It provides a simple and low-overhead file transfer service. TFTP provides unreliable data transfer over

UDP and does not provide any access authorization and authentication mechanism. It employs the

timeout retransmission method to implement best-effort delivery of data. Compared with FTP, TFTP has a

much smaller software size.

Follow these steps to upgrade an application through the management Ethernet interface:

Step1 Set up a software upgrade environment. Connect the 10/100/1000Base-TX management interface to a

PC with an Ethernet cable.

Step2 Run TFTP Server on the PC, and set the path of the application file to be downloaded.

NOTE:

The TFTP server software is not provided with the WX6103 access controller. You must make sure that it is

available by yourself.

Step3 Modify the Ethernet interface parameters. For more information, see “Configuring Ethernet interface

parameters.”

Step4 Select 3 in the BootWare main menu to enter the Ethernet interface submenu. The following example

shows how to upgrade the main application file. Select 2 in the Ethernet interface submenu. The

following information appears:
