This window allows you to set the following features:
Parameter Description
From [ ] To [ ] Enter the port or ports to be set.
Sets the administrative-controlled direction to either in or both.
AdmCtrlDir
If in is selected, control is only exerted over incoming traffic through the port you selected in the
first field.
If both are selected, control is exerted over both incoming and outgoing traffic through the
controlled port selected in the first field.
PortControl This allows you to control the port authorization state.
Select forceAuthorized to disable 802.1X and cause the port to transition to the authorized state
without any authentication exchange required. This means the port transmits and receives
normal traffic without 802.1X-based authentication of the client.
If forceUnauthorized is selected, the port will remain in the unauthorized state, ignoring all
attempts by the client to authenticate. The Switch cannot provide authentication services to the
client through the interface.
If Auto is selected, it will enable 802.1X and cause the port to begin in the unauthorized state,
allowing only EAPOL frames to be sent and received through the port. The authentication
process begins when the link state of the port transitions from down to up, or when an EAPOL-
start frame is received. The Switch then requests the identity of the client and begins relaying
authentication messages between the client and the authentication server.
The default setting is Auto.
This sets the TxPeriod of time for the authenticator PAE state machine. This value determines
TxPeriod
the period of an EAP Request/Identity packet transmitted to the client. The default setting is 30
seconds.
QuietPeriod This allows you to set the number of seconds that the Switch remains in the quiet state following
a failed authentication exchange with the client. The default setting is 60 seconds.
