Unanswered Question

Hi All,

Per Cisco recomendation Iam planning to upgrade IOS on 7206VXR (NPE-G2).


From 'sh Ver' :

System image file is "disk2:c7200p-advsecurityk9-mz.124-4.XD3.bin"

Sh bootflash:


show bootvar

BOOT variable does not exist

CONFIG_FILE variable does not exist

BOOTLDR variable does not exist


Configuration register is 0x2102


In the running config , I do not see

anywhere 'boot system disk2:' command. So the rtr picking up the IOS from disk2 without any bootvar..?

Also, when I upload the new IOS to 'disk2' do I have to issue the 'boot system disk2: c7206newios....bin' then same command with old IOS file to boot with new IOS..?

please advise.

Thank you inadvance


I have this problem too.

The router looks for the first IOS image and boots it if there is not "boot system" statement. If you plan to have two images on the disk you will need the "boot system" statement pointing to the image you want loaded. If there will only be one image you should not need the "boot system" command.

HTH and please rate.

Thank you for your quick reply. The other question I have on this is...


why the router did not pickup this image while booting-instead picked Disk2 image. Iam not sure, but this is not valid image..?

Please clarify.

Thank you in advance.

This is a boot image, kind of like the rommon image but for 7200's. If you were to delete all the IOS images and you rebooted you go into this bootflash.
