Re-Authenticating a Port
You can congure the authenticator for periodic re-authentication.
After the supplicant has been authenticated, and the port has been authorized, you can congure the authenticator to re-authenticate the
supplicant periodically. If you enable re-authentication, the supplicant is required to re-authenticate every 3600 seconds by default, and you
can congure this interval. You can congure the maximum number of re-authentications as well.
To congure re-authentication time settings, use the following commands:
• Congure the authenticator to periodically re-authenticate the supplicant.
INTERFACE mode
dot1x reauthentication [interval] seconds
The range is from 1 to 31536000.
The default is 3600.
• Congure the maximum number of times the supplicant can be re-authenticated.
INTERFACE mode
dot1x reauth-max number
The range is from 1 to 10.
The default is 2.
