You can use the no dot1x reauth-max command to restore the maximum number of
re-authentications to its default. The following example sets the maximum number of
re-authentications to 3:
DES-7200# configure terminal
DES-7200(config)# dot1x reauth-max 3
DES-7200(config)# end

during the authentication process, please see “Authentication Initiation and Packet Interaction
During Authentication”.
However, authentication needs to be initiated by the switch in some cases. For example, when
the switch is reset and the status of the authentication port changes from linkdown to linkup,
the switch needs to automatically initiate authentication to ensure that the authenticated users
