Downloading a System File
This section contains the following procedures:
ˆ “Downloading a File from a Local Management Session” on page 203
ˆ “Downloading a File from a Telnet Management Session” on page 207
Both procedures are used to download files into a switch’s file system.
One procedure downloads files from a local management using either
Xmodem or TFTP, and the other explains how to do it from a Telnet
management session, which only supports TFTP.
There are only two files that you are ever likely to download into a switch’s
file system:
ˆ Boot configuration file
ˆ Certificate enrollment request
You might have edited a boot configuration file at your management
workstation and want to download it onto a switch prior to designating it as
the active boot configuration file. Or, you might have obtained a CA
certificate for the switch to add encryption to your web browser
management sessions.
You can also use this procedure to store an AT-S62 image file in the
switch’s file system. However, downloading an image file into the file
system should be performed with care. First, for an image file to be the
active image file on a switch it has to be stored in the switch’s application
block, which is a separate part of flash memory from the file system.
Second, the image file will take up almost all 2 megabytes of the file
system, leaving little room for other files. If you want to download an
AT-S62 image file so that it is the active image file on the unit, see
“Downloading a New AT-S62 Image File onto a Switch” on page 188 or
“Uploading an AT-S62 Image File Switch to Switch” on page 196.
Guidelines
Review the following guidelines before downloading a file onto a switch.
ˆ You can use either Xmodem or TFTP to download files from a local
management session.
ˆ You must use TFTP to download files from a Telnet management
session.
ˆ You cannot download a private encryption key onto a switch, but you
can a public key. However, since the switch can only use those
encryption keys it has generated itself, Allied Telesyn recommends
against downloading any keys onto the switch.
