Dale:
There has been a lot said here and as you can see, there are as many
"strategies" as there people going to take the lab.
I do agree with Gaurav concerning practicing what ever strategy you employ
over and over in different lab scenarios. This way you will be consistent in
the approach you take. In the National Guard - the motto was "Train like you
fight".
To answer your first question, I would not begin by shutting down the switch
ports unless there was a requirement to that led you to do so. Depending
upon your topology, this could break something and you might spend extra
time trying to fix something that you broke yourself.
If you would like to work together to come up with a strategy, please send
me an email off the list and I'd be happy to work with you.
