Boot Options

Introduction

You must be logged in to the switch as the administrator to use the Boot Options commands.

The Boot Options allow you to perform the following functions:

Select a switch software image to be used when the switch is next reloaded.

Select a configuration block to be used when the switch is next reloaded.

Download or upload a new software image to the switch via TFTP.

Each of the Boot Options commands is discussed in the following sections.

Updating the switch software image

The switch software image is the executable code running on the switch. A version of the image ships with the switch, and comes pre-installed on the switch. As new versions of the image are released, you can upgrade the software running on the switch.

To upgrade the software image on the switch:

Load the new image onto a TFTP server on your network.

Download the new image from the TFTP server to the switch.

Select the new software image to be loaded into switch memory the next time the switch is reloaded.

Downloading new software to the switch

The switch can store up to two different software images, called image1 and image2, as well as boot software, called boot. When you download new software, you must specify where it should be placed: either into image1, image2, or boot.

For example, if your active image is currently loaded into image1, you would probably load the new image software into image2. This lets you test the new software and reload the original active image (stored in image1), if needed.

To download new software to the switch, you need the following:

The image or boot software loaded on a TFTP server on your network

The hostname or IP address of the TFTP server

The name of the new software image or boot file

NOTE: The DNS parameters must be configured if specifying hostnames. See the “Domain name system configuration” section in the “Configuration Commands” chapter.

When the above requirements are met, use the following procedure to download the new software to the switch.

1.In Privileged EXEC mode, enter:

Router# copy tftp {<image1image2boot-image>}

2.Enter the name of the switch software to be replaced:

Enter name of switch software image to be replaced ["image1"/"image2"/"boot"]: <image>

3.Enter the hostname or IP address of the TFTP server:

Enter hostname or IP address of TFTP server: <server name or IP address>

4.Enter the name of the new software file on the server:

Enter name of file on TFTP server: <filename>

The exact form of the name will vary by TFTP server. However, the file location is normally relative to the TFTP directory.
