Appendix B Upgrading software

This appendix describes how to upgrade the software on a switch.

Software used for upgrade

The software used on a switch includes:

 BootWare image—Contains a basic section and an extended section. The basic section is the

minimum code that bootstraps the system. The extended section enables hardware initialization

and provides system management menus.

When you upgrade the BootWare, upgrade both the basic section and extended section to avoid

compatibility problems.

 System software image—Contains hardware drivers and service features. There are two types of

system software image: main, and backup.

At startup, the switch always attempts to boot with the main system software image. If the attempt

fails, the switch tries to boot with the backup system software image.

The BootWare and system software images might be Featured separately or as a whole in one .bin

package file. Typically, these images for this switch series are Featured in one .bin file such as main.bin.

NOTE:

You can change the type for the main or backup system software image by using the CLI or BootWare

menu.

Upgrade methods

You can upgrade the software by using one of the following methods:

Upgrading method

Remarks

Upgrading from the CLI

 You must reboot the switch to complete the upgrade.

 This method can interrupt ongoing network services.

Upgrading from the BootWare

Use this method when the switch cannot correctly start up.

CAUTION:

Upgrade an IRF fabric from the CLI rather than the BootWare menu.

The BootWare menu approach requires that you upgrade the member

switches one by one.
