How can we locate the name of the IOS image. I need it to take the backup.
your copy command should be:
copy disk1: tftp:
Then follow the questions.
Use disk1: and not slot0:.
When you boot your router, it boots the first image it finds on the disk1:. It is fine as you have 1 image only. If you have more than one image you should set the boot var, the command is boot system disk1:7200.bin for you.
