After configuring 802.1x on the printer and switching it over to a secured network, if authentication is successful printer retains connectivity and if it fails it loses connectivity. In case of authentication failure, it does not acquire connectivity even when switched over to an unsecured network. 802.1x failsafe is a feature which allows printer to retain connectivity in a unsecured network even if authentication fails. Setting this OID to 1 enables this feature and setting to 0 disables this feature. Connect anyway (802.1x Fail-Safe) ( 1 ) Block network (secure failure) ( 0 )
