I'm not very familiar with IBM's token ring having grown up on ethernet, so my
question may be a little naive.

On most ethernet cards there is a promiscuous mode that allows stations to
monitor all traffic.  This is very useful for example for a LAN watching
device, an ethernet bridge or a hacker bent on getting some passwords.

I have heard (second hand from IBM) that on token rings while promiscuous mode
is available on some boards that there is a way to restrict it to just certain
stations.  Is this a general facility provided by the token ring protocols?
How is this identification enforced?  What do I have to buy?

We may be basing alot of our campus security on such a scheme, so I'm very
interested to discover any and all details.
