Equip yourself with better users?  Well why we didn't we think of that sooner!? 
 That will solve so many problems!

Thanks Andrew, your insightfulness is outstanding.

Then (since we're all so full of impractical advice today), you might do well 
to equip your environment with better users, who don't move around the switches 
themselves, or otherwise touch the configuration that the admin puts into 
place.  (After all, if the admin is the one putting it into place, he or she 
can configure the managed switches in the environment to avoid looping, right?)



Hey, feel free to do what you want in your environment, whether based on 
experience or not.  But don't be surprised if other people, with their own set 
of valid experiences, choose to disagree with what you deem to be universal 
truths.

I have backed up my words with real world examples.

As I stated before, I have lots of experience with folks creating
layer 2 loops with small unmanaged switches over the past 9+ years at
my position. If it costs even one hour of my time tracking these down
for each incident (and it's usually more than that), the money spent
is well worth it to both me and the business.

It happens about twice a year, and sometimes more frequently. At a
fully burdened hourly rate of approximately $75.00/hour just for my
time, not to mention the time of all of the people affected who can't
do their jobs for at least an hour at a time, it is stunningly bad
business *NOT* to have pulled sufficient cable and bought sufficient
ports to support the requirements of the environment.
