Chapter 3 Configurations for the Layer 3 Switch Router

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 Layer 3 switch router, initiate a Telnet session or console connection to the Layer 3 switch router, perform the following task in privileged EXEC mode:

	Command	Purpose
Step 1
	Router# dir bootflash:	Display the contents and available space in bootflash memory. If
		there is not enough free space to copy the new system image, do
		Steps 2 through 5. If there is enough space, proceed to Step 4.
Step 2
	Router# copy tftp: bootflash:	Erase bootflash memory and copy a file from a TFTP server to
		bootflash memory. Make sure you copy the known good system
		image file.
Step 3
	Router# dir bootflash:	Display the contents of bootflash memory. This step confirms that
		space was available in bootflash memory and the known good
		image file was copied as expected. You can then proceed to
		download the latest image.
Step 4
	Router# copy tftp: bootflash:	Initiate a TFTP session to copy the new system image from the
		TFTP server.
Step 5
	Router# dir bootflash:	Display the contents of bootflash memory again, to confirm that
		the latest image file was copied as expected.

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

Router# copy tftp bootflash:

Address or name of remote host []? 172.10.00.00
