Description
Select a range of ports you wish to configure.
This allows the user 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.
This value determines timeout conditions in the exchanges between the
Authenticator and the client. The default setting is 30 seconds. It is defined in
SuppTimeout, IEEE-802.1X-2001, page 47. The initialization value is used for the
awhile timer when timing out the Supplicant. Its default value is 30 seconds;
however, if the type of challenge involved in the current exchange demands a
different value of timeout (for example, if the challenge requires an action on the
part of the user), then the timeout value is adjusted accordingly. It can be set by
management to any value in the range from 1 to 65535 seconds.
This value determines timeout conditions in the exchanges between the
Authenticator and the authentication server. The default setting is 30 seconds.
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.
It is defined in MaxReq, IEEE-802.1X-2001 page 47. The maximum number of
times that the state machine will retransmit an EAP Request packet to the
Supplicant before it times out the authentication session. Its default value is 2; it can
be set by management to any value in the range from 1 to 10.
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.
A constant that defines a nonzero number of seconds between periodic re-
authentication of the client. The default setting is 3600 seconds.
Determines whether regular re-authentication will take place on this port. The
