802.1x port-based authentication provides RADIUS client authentication and data encryption
features (see
Appendix C, “802.1x Port-Based Authentication Overview”). If you have a
RADIUS server on your network, you can have authentication of port access done through the
RADIUS server. This does affect traffic passing through the switch, which can be helpful is
securing your network from wireless eavesdropping when a wireless access point is connected to
the switch. To enable 802.1x, provide the IP address of the RADIUS server, and the shared secret
authentication key. The re-authorization timer determines how frequently the session will refresh
the data encryption with a new key.
