The following is an example of how to start a TFTP session to download a file from a TFTP server:

-> tftp 10.211.17.1 get source-file boot.cfg destination-file /flash/working/

boot.cfg ascii

When you enter the above command the following actions are performed:

• Establishes a TFTP session with the TFTP server 10.211.17.1.

• Downloads the boot.cfg file using the ASCII file transfer mode.

• Saves the downloaded file contents to the boot.cfg file in the working directory of the TFTP client.

You can specify a path for the specified file and if the file name is specified without a path then the 
current path (/flash) is used by default. If a destination filename is not specified, then the source filename 
is used by default. A TFTP client supports two modes of file transfer: Binary mode and ASCII mode. 
However, files are transferred using the Binary mode by default.

A TFTP server does not prompt for a user to login and only one active TFTP session is allowed at any 
point of time.

Note. When downloading a file to the switch, the file size must not exceed the available flash space.

A Zmodem application has been included with your switch software so that new programs and archives 
can be uploaded through the switch’s serial console port. There are generally two situations that would 
require you to use the switch’s console serial port to load software by using Zmodem.

• Your system is having problems and the FTP transfer method does not work.

• The switch’s Ethernet Management port is either not functioning or not configured.

To use Zmodem, you must have a terminal emulator that supports the Zmodem protocol. There are many 
Zmodem products available that operate differently. You should consult the user manual that came with 
your terminal emulation software for details.

Note. If a file you are transferring already exists in the switch’s flash memory, you must remove the file 
before transferring the new file via Zmodem.

To transfer a file via Zmodem, complete the following steps:
