Configuring the IEEE 802.1X Flexible Authentication feature to support Layer 3 authentication mechanisms involves adding MAC Authentication Bypass (MAB) into the switch configuration. This allows devices that do not support 802.1X to be authenticated using their MAC address. Once MAB identifies the device, it can then be redirected to a Layer 3 device for further authentication, thus providing a mechanism to support devices requiring Layer 3 authentication methods.

Certificate authorities (CAs) are responsible for issuing, renewing, revoking, and publishing digital certificates. They also maintain a certificate revocation list (CRL), which is a database of revoked certificates that can be checked by relying parties to verify the validity of a certificate. Registration authorities (RAs) are entities that assist CAs with the verification of user identities and enrollment requests. They do not issue certificates themselves, nor do they have access to the CRL. Therefore, CRL publishing is a function that is performed by CAs but is a limitation of RAs. References :=

 Cisco ISE is a solution that allows an administrator to provision, monitor, and secure mobile devices on Windows and Mac computers from a centralized dashboard. Cisco ISE integrates with Mobile Device Management (MDM) servers to provide necessary insight into the posture of mobile devices and enforce network access policies. Cisco ISE can also perform device registration, remediation, and periodic compliance checks on mobile devices. Cisco ISE can also issue remote actions on the device through the MDM server, such as full wipe, corporate wipe, and PIN lock. Cisco ISE can also augment endpoint data with information from the MDM server that cannot be gathered using the Cisco ISE profiling services. References:
