I have a remote site (US to AUS) that I need to upgrade the IOS on a 3750 from ver 12 to 15 (one switch).
I have tried to use the Cisco Network Assistant to push the new software and it fails within a few seconds. I thought about loading CNA on a computer there with the image and then push it locally. When it gets to the point when it asks for a reload, would I be able to hit that across our ASA tunnel with a shell. I am trying to keep access to the switch until the upgrade completes without setting up a local TFTP server, etc...
Any better method, or command line options that are best for remote upgrades.
Due to time zones they are out of the office when I am working with the switch.
Thanks in advance
