1. Use the following command to save the configuration. Unsaved changes will be lost during the upgrade
procedure.
RBT-8xx0# save config [filename]
2. The following command should be used to back up the switch‘s files:
RBT-8xx0# backup system [tftp://ip-addr/]filename [all | critical]
3. To restore a switch that has been backed up, use the following command:
RBT-8xx0# restore system [tftp://ip-addr/]filename [all | critical] [force]
The ―Upgrade Scenario‖ listed below shows an example use of the backup command. For more information about
these commands, see the ―Backing Up and Restoring the System‖ section in the ―Managing System Files‖
chapter of the RoamAbout Mobility System Software Configuration Guide.
Note: If you have made configuration changes but have not saved the changes, use the save config
command to save the changes, before you back up the switch.
If the RAS is running an earlier version of firmware, use the copy tftp command to copy files from the switch onto
a TFTP server.
Upgrading an Individual Switch Using the CLI:
1. Save the configuration, using the save configuration command.
2. Back up the switch, using the backup system command.
3. Copy the new system image onto a TFTP server.
For example, login to http://www.enterasys.com/download/ using a web browser on your TFTP server and
download the image onto the server.
4. Copy the new system image file from the TFTP server into a boot partition in the switch‘s nonvolatile
storage. You can copy the image file only into the boot partition that was not used for the most recent
restart. For example, if the currently running image was booted from partition 0, you can copy the new
image only into partition 1.
5. Set the boot partition to the one with the upgrade image for the next restart.
a. To verify that the new image file is installed, type show boot.
6. Reboot the software.
a. To restart an RBT switch and reboot the software, type the following command:
RBT-8xx0# reset system [force]
After resetting the RBT switch, the switch boots using the new image. The RBT switch also sends the AP
version of the new boot image to the configured APs and restarts the APs. After an AP restarts, it checks
the version of the new AP boot image to make sure the boot image is newer than the boot image
currently installed on the AP. If the boot image is newer, the AP completes installation of its new boot
image by copying the boot image into the AP‘s flash memory, which takes about 30 seconds, then
restarts again. The upgrade of the AP is complete after the second restart.
