• Thirdly, if neither a temporary install nor a preferred install is specified,
the router loads the default install. The default install is always present
in the router because if, for some reason, it is not, the INSTALL module
will restore it.
The preferred install should not be set up with an untested release or patch.
It is advisable to install new releases or patches as the temporary install, and
when the router boots correctly, to then set up the preferred install with the
new release or patch.
To change the install information in the router, enter the command:
set install={temporary|preferred|default}
[release={release-name|eprom}] [patch=patch-name]
For security reasons the SET INSTALL command is only accepted if the user has
SECURITY OFFICER privilege.
When you set a patch file as part of a temporary install or permanent install,
you must also set the corresponding release file in the same command, if it has
not already been set as part of that install. You can set the patch, but not the
release (always EPROM), for the default install.
To delete a temporary install or preferred install, enter the command:
delete install={temporary|preferred}
If a default install is set, only the patch information is deleted using the
DELETE INSTALL command as the release information must always be left
intact in the default install.
To display the current install information, including which install is currently
running in the router, and how the install information was checked at the last
reboot, enter the command:
show install
For more information about INSTALL commands, see the Operations chapter in
the Software Reference.
Example: Upgrade to a New Software Release
Using TFTP
This example assumes the router is correctly configured to allow TFTP to
function. This means that IP is configured and the router is able to
communicate with the designated TFTP server. The TFTP server is assumed to
function correctly and the release and patch files are assumed present in the
server’s TFTP directory. The router has no release or patch files, and is running
the EPROM Software Release 2.3.2. The IP address of the server is 172.16.1.1.
The name of the release file being loaded is
52-241.rez.
To upgrade to a new software release:
1. Configure the LOADER.
The LOADER module is set up with defaults to make the process of
downloading files in future simpler. All release and patch files in this
router are stored in FLASH.
set loader method=tftp server=172.16.1.1 dest=flash
