[unisog] Network security police no hubs/switches/routers?

In the early 1990s, we allowed departments to deploy thinnet and 10BaseT 
hubs on the campus network. As time went on, we found ourselves devoting 
more and more of our time (at times between 25-50%) chasing problems in 
these environments. At peak, they only represented between 5-10% of station 
count on our network. After demonstrating this point to my administration 
of the time, support emerged for a policy that forbid the use of these 

Over the years through this policy, we have developed a uniform environment 
that is consistent throughout campus. This approach has reduced the amount 
of time we invest chasing ghosts which allows us to focus our efforts on 
other endeavors. These days with the security threats of the last couple of 
years fresh in their memory, the administration here is more concerned with 
network reliability and responsiveness which supports this viewpoint.

If you are trying to make this point, track the number of hours your staff 
has invested chasing problems that have emerged with the use of these 
devices. Then, demonstrate what you can't get done because of it. These 
were selling points when we made our pitch so many years ago.
