Re: Catalyst 4500 IOS Upgrade

cat4000_flash is where the vlan.dat is store.

You can verify this by doing dir cat4000_flash

You will store the IOS image in bootflash or purchase a flash card and insert it in slot 0: for additional IOS storage.

Yes supII plus will support any images that cisco has out there . That image is really older you might want to check out the newer ones which is either 12.2.20 EWA9 or the newer 12.2.37 SG code.
