This chapter describes the procedure for upgrading the Switch software
image. It also covers how to save and load a primary and secondary
configuration file on the Switch.
Upgrading the
Software
The image file contains the executable code that runs on the
Switch 3800. It comes preinstalled on the Switch from the factory. As
new versions of the image are released, you should upgrade the
software running on your Switch.
The image is upgraded by using a Trivial File Transfer Protocol (TFTP)
server on the network. Downloading a new image involves the
following:
■
Load the new image onto a TFTP server on your network.
■
Download the new image to the Switch 3800 using the following
command:
download image <ipaddress> <filename> {primary | secondary}
where:
■
ipaddress — is the IP address of the TFTP server
■
filename — is the filename of the new image
■
primary | secondary — (optional) indicates the image to which
you want the file downloaded. If no parameter is specified, the
file is saved to the primary image.
The Switch 3800 can store up to two images; a primary and a
secondary. When you download a new image, you must select into
which image space (primary or secondary) you want the new image to
be placed.
