Chapter 3 Initial Switch Router Configurations

Updating the System Image

To copy both the known good system image and the new system image from a TFTP server to the file system on your switch router, initiate a Telnet session or console connection to the switch router. Perform the following steps in privileged EXEC mode:

 

Command

Purpose

Step 1

 

 

Router# dir bootflash:

Displays the contents and available space in boot flash memory.

 

 

If there is not enough free space to copy the new system image,

 

 

perform steps 2 through 5. Otherwise, proceed to Step 4.

Step 2

 

 

Router# copy tftp: bootflash:

Erases boot flash memory and copies a file from a TFTP server to

 

 

boot flash memory. Make sure you copy the known good system

 

 

image file.

Step 3

 

 

Router# dir bootflash:

Displays the contents of boot flash memory. This step confirms

 

 

that space was available in boot flash memory and the known

 

 

good image file was copied as expected. You can now proceed

 

 

with downloading the latest image.

Step 4

 

 

Router# copy tftp: bootflash:

Initiates a TFTP session to copy the new system image from the

 

 

TFTP server.

Step 5

 

 

Router# dir bootflash:

Displays the contents of boot flash memory. This step confirms

 

 

that the latest image file was copied as expected.

 

 

 

The following example shows how to erase a full boot flash memory file system, copy a known good image, and copy the latest image using TFTP:

Router# dir bootflash:
