In general, 802.1x has become the accepted standard for port level access security. However, the fact that it requires an 802.1x client on each host prevents it from being implemented in many places.

We are looking at doing port security where I work. However, it will be an admin nite mare, because of the many switches that we have. I recall reading somewhere (many, many, many, books and bottles of no dose ago) that one can use a centralized database in order to hold the MAC's. The switches would be able to authentic from that centralized database using TACAS. Would you happen to know anything about this? If you do, would you be kind enuf to point me in the correct direction, so that I can get it implemented? Thanks in advance, and you have a great site!
