Note Critical authentication, which is also known as Inaccessible Authentication Bypass or AAA Fail Policy,
does not support the Identity features on the Onboard Gigabit Ethernet Layer 3 ports.
Authentication Methods
Identity features support various types of authentication methods that are suitable for different kinds of
end hosts and users. The two methods that are mainly used are:
• IEEE 802.1X
• MAC Authentication Bypass (MAB)
