Re-authenticating a Port
Periodic Re-authentication
After the supplicant has been authenticated, and the port has been authorized, the authenticator can be
configured to re-authenticates the supplicant periodically. If re-authentication is enabled, the supplicant is
required to re-authenticate every 3600 seconds, but this interval can be configured. A maximum number of
re-authentications can be configured as well.
To configure a re-authentication or a re-authentication period:
To configure a maximum number of re-authentications:
FTOS(conf-if-Te-0/0)#dot1x reauthentication interval 7200
FTOS(conf-if-Te-0/0)#dot1x reauth-max 10
