Therefore, you should only connect trusted pieces of equipment to a
level-2 media unless it is being used as a point-to-point media. Lets use
Ethernet as an example. If you connect a customer web server to an
Ethernet then they can sniff any traffic that goes by and possibly do
nasty things like spoofing. Even if they would never do such a thing they
may be hacked by somebody who would do such a thing. So it is not a good
idea to share a level 2 media in this way.

The MAE's are switches.  Unless you are sending super secret BROADCAST
traffic the security implications you are mentioning are non-existant.

What about people hacking MAC addresses or screwing around with ARP and
BOOTP? He was asking about attaching a customer web server to the exchange
so presumably anything could be done on that box.
