The security team wants to secure the wired network. A legacy printer on the network with the MAC address 00:43:08:50:64:60 does not support 802.1X. Which setting must be enabled in the Allowed…

MS-CHAPv2 is an EAP method primarily used for password-based user authentication, not for MAC-based authentication bypass.

EAP-TLS is a certificate-based EAP method used for strong 802.1X authentication, not for MAB where 802.1X is unsupported.

PAP (Password Authentication Protocol) is an older, less secure authentication method that transmits credentials in plain text and is not directly related to enabling MAB for devices lacking 802.1X support.

For Cisco ISE to perform MAC Authentication Bypass (MAB) for devices that do not support 802.1X, such as legacy printers, the "Process Host Lookup" option must be enabled in the Authentication Policy's Allowed Protocols list. This setting instructs ISE to look up the connecting device's MAC address against an internal identity store or endpoint database for authentication.
