User Guidelines
The re-authentication process sends an authentication message (EAP-
Request/Identity)to authenticated supplicants asking them to re-
authenticate themselves. If a supplicant fails re-authentication, it is denied
access to switch resources. Re-authentication must be enabled for this setting
to have any effect.
Command History
Syntax updated in version 6.6 firmware.
