28WIRELESS LAN SWITCH AND CONTROLLER MSS VERSION 6.0.4.6 RELEASE NOTES

during the upgrade, you can restore your switch to its previous state.

Use this command to back up the switch’s files:

backup system [tftp://ip-addr/]filename[all critical]

To restore a switch that has been backed up, use the following command:

restore system [tftp://ip-addr/]filename[all critical] [force]

“Upgrade Scenario” on page 28 of these Release Notes shows a sample 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 Wireless LAN Switch and Controller Configuration Guide.

If you have made configuration changes but have not saved the changes, use the save config command to save the changes before you backup the switch.

If the switch is running an earlier version of MSS, use the copy tftp command to copy files from the switch onto a TFTP server.

Upgrading an Individual Switch Using the CLI

1Back up the switch, using the backup system com- mand. (See “Preparing the WX Switch for the Upgrade” on page 27.)

2Copy the new system image onto a TFTP server.

3Copy the new system image file from the TFTP server to 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.

4Set the boot partition to the one with the upgrade image for the next restart.

To verify that the new image file is installed, type dis- play boot.

5Reboot the software.

To restart a WX switch and reboot the software, type the following command:

reset system [force]

When you restart the WX switch, the switch boots using the new MSS image. The switch also sends the MAP version of the new boot image to MAPs and restarts the MAPs. After a MAP restarts, it checks the version of the new MAP boot image to make sure the boot image is newer than the boot image currently installed on the MAP. If the boot image is newer, the MAP completes installation of its new boot image by copying the boot image into the MAP’s flash memory, which takes about 30 seconds, then restarts again. The upgrade of the MAP is complete after the second restart.

Upgrade Scenario

To upgrade a switch (WX1200 used in this example) type commands such as the following.

This example copies the image file into boot partition 1. On your switch, copy the image file into the boot partition that was not used the last time the
