Quick BOOT SYSTEM command question

Unanswered Question
Dec 9th, 2007

I tried upgrading code on a switch to 12.2(18) SXF7.

I had 12.2(18) SXF7 loaded onto a PCMCIA flash card that was inserted slot 0.

So, I changed the boot system commnads to the following:

boot system flash disk0:s222-adventerprisek9_wan-mz.122-18.SXF7

boot system flash sup-bootflash:c6sup22-jk2sv-mz.121-13.E13

I wanted the 12.2(18) to load first and if it failed to use the old code as a backup.

The switch wouldnt load the new IOS until I added the ".bin" file extension to the boot system command for the 12.2(18) SXF7.

Why?

Why did I not have to do that for the old IOS that was in sup-bootflash and that I left as a backup?

It was a 6500 switch with a SUP 2 module.

It is basically a function of how Cisco named the images (or how you named the images as you copied them to flash or bootflash). To be sure what name to use in the boot system command use the the appropriate show or dir command to see the content of disk0 or bootflash and verify the image name there.
