Help with router reload lab

2URGSE

This is from the CCNA Simulator, ICND 1, Skill Builder --> Migrating to a new IOS image.

The lab went fine, I copied a new IOS file from a tftp server to the router.

I then go to global config mode and type:

boot system flash c2800nm-avipservicesk9-mz.124-21.bin

Copy running-config startup-config

Reload


The router should than reload the new IOS file instead of the first one it has (It has a total of 2 files saved in flash)

but it loads the last file and the lab tells me I didn't do it right.

Do "no boot system" first. You need to get rid of any existing boot system line in the configuration.

It will help if you spell the image name correctly;

boot system flash c2800nm-avipservicesk9-mz.124-21.bin
needs to be
boot system flash c2800nm-advipservicesk9-mz.124-21.bin

Like mgeorge said you need to get the boot statement straightened.

If thats corrected already and you still see same results, probably the other IOS is a newer/higher one and thats why router is booting into newer IOS.

cheers

Heero

if the boot statement is incorrect, the router will just boot from the first ios image it finds in flash...

ROMMON doesn't check for version numbers.

You are correct, if the image in boot statement is valid then router will boot from there and not from image with higher version ( if there was one on flash)

but I should have stated if no boot statement and there are two images in the flash then router will boot from image with higher version ....is this is a correct statement?

If there are two it will boot the first image it comes across. Do a show flash and you can see the order they are listed.
