Operating the switch 59
Software Release 2.6.1
C613-02025-00 REV C
Example: Upgrade to a New Software Release Using
TFTP
This example assumes the switch is correctly configured to allow TFTP to
function. This means that IP is configured and the switch 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 switch has no patch files, and is running the
Software Release 2.6.1. The IP address of the server is 172.16.1.1. The name of
the release file being loaded is
86s-262.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
switch are stored in FLASH.
SET LOADER METHOD=TFTP SERVER=172.16.1.1 DEST=FLASH
2. Load the new release file onto the switch.
Make sure there is space in FLASH for the new release file. Load the new
file onto your switch. Make sure the release file matches your switch model
(see “Upgrading Switch Software” on page 57). Load any patch files
required, and the help file for the release (see “Loading and Uploading Files”
on page 53). To load the release file using your LOADER default settings,
enter the command:
LOAD FILE=86s-262.rez
Wait for the release to load. This can take several minutes, even if you are
loading the file over a high speed link. To see the progress of the load, enter
the command:
SHOW LOAD
To check that the files are successfully loaded, enter the command:
SHOW FILE
3. Enter licence information for the release.
Enter the licence password for the software release.
ENABLE RELEASE=86s-262.rez PASSWORD=ce645398fbe
NUMBER=2.6.2
The release licence password is provided by your authorised distributor or
reseller and is unique for the release number (in this case 2.6.2), the file
name and the router’s serial number.
Enter passwords for any special feature licences.
ENABLE FEATURE=feature PASSWORD=password
4. Test the release.
Set the new release to run as a temporary install. This sets the switch to
load the new release once only when it reboots.
SET INSTALL=TEMPORARY RELEASE=86s-262.rez
If you want to use the current switch configuration again, store the
dynamic configuration as a configuration script file and set the switch to
use this configuration when it restarts. Releases are generally backward-
