There can be security at Level 2

[Mike Trest <trest () atmnet net>]

I have recently read these statement on this list:

> > [snip] There is no security at level 2.

> Yes there is rudimentary security at L2.  It's called MAC-based filtering,

Full IP filtering (to port level) is in use today at OC3 and OC12 at the
edges of some relatively large ATM clouds.  [Yea, I know its IP over ATM,
but please do not waste energy on that flame-track.]  

It works with lots of ACL lists and multiple interfaces simultaneously.  In
one application it is working in conjunction with wire speed per-VC
encryption to boot!  

I will provide a vendor contact via EMAIL to any who request.
