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.
