You may alreedy know this, but dot1x (IEEE 802.1X) does port-based access control.
IEEE 802.1X provides a means for authenticating and authorizing devices attached to a LAN port. It's a somewhat popular method for restricting access to a switch port based on username/password combination or a certificate. Credentials are verified by a RADIUS server. >From a protocol standpoint, I can't think of any reason that it would disable high availability. This restriction must be some weird implementation issue for the 6509 software. You can get the dot1x specification from IEEE, as you probably know. IEEE now makes their standards available for free. They publish them on their Web site after they've been available for six months in PDF format.
