Parameter Description
From [ ] To [ ] Enter the port or ports to be set.
AdmCtrlDir Sets the administrative-controlled direction to either
in
or
both
.
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
.
TxPeriod This sets the TxPeriod of time for the authenticator PAE state machine. This value
determines 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.
SuppTimeout This value determines timeout conditions in the exchanges between the Authenticator and
the client. The default setting is
30
seconds.
ServerTimeout This value determines timeout conditions in the exchanges between the Authenticator and
the authentication server. The default setting is
30
seconds.
MaxReq The maximum number of times that the Switch will retransmit an EAP Request to the client
before it times out of the authentication sessions. The default setting is
2
.
ReAuthPeriod A constant that defines a nonzero number of seconds between periodic reauthentication of
the client. The default setting is
3600
seconds.
ReAuth Determines whether regular reauthentication will take place on this port. The default setting
is
Disabled
.
