It's not a matter of experience. It's a matter of what a level-2 device is and how it normally works. There is no security at level 2.
Yes there is rudimentary security at L2. It's called MAC-based filtering, which is a feature of DEC's GIGAswitch. I believe that SprintLink uses the capability in a form to logically separate backbone router traffic from access router traffic when both routers are homed to the same GIGAswitch. With filtering, you can establish virtual workgroups where only certain devices can communicate with other devices in the same group, or with specific devices in other groups. ss ******************************************************************************** Phone: 1.816.854.2113 Fax: 1.816.854.2201 Sprint Pager: 1.888.366.7890, PIN 398.6644 Text Page via Internet: 3986644@pagenet.net ********************************************************************************
