802.1X - Settings page (Cont.)
Admin State: Sets the authentication mode to one of the following options:
• Auto - Requires a 802.1X-aware client to be authorized by the authentication
server. Clients that are not 802.1X-aware will be denied access.
• Force-Authorized - Forces the port to grant access to all clients, either
802.1X-aware or otherwise.
• Force-Unauthorized - Forces the port to deny access to all clients, either
802.1X-aware or otherwise.
Port State:
The state of the port.
Reset:
Two options are available:
• Re-Authenticate - Schedules a reauthentication to whenever the quiet-period
of the port runs out.
• Force-Reinitialize - Bypasses the quiet-period of the port and enables
immediate reauthentication regardless of the status for the quiet-period.

The reason for the “quiet-period”: If a re-authentication fails, the IEEE 802.1X
standard enforces a so-called “quiet-period” in which the authenticator (switch) shall
be quiet and not re-try another authentication – also packets from the supplicant are
discarded. In this way, “brute-force” attacks are prevented.
