Setting and Enabling Automatic Reauthentication of the Host

You can specify how often 802.1x authentication reauthenticates the host if you do so before you enable
automatic 802.1x host reauthentication. If you do not specify a time period before you enable host
reauthentication, 802.1x defaults to 3600 seconds (the valid values are from 1–65,535 seconds).
You can enable automatic 802.1x host reauthentication for hosts that are connected to a specific port. To
manually reauthenticate the host that is connected to a specific port, see the
