        Cisco Identity Services Engine MAC Address Lookup Might Fail with Android 10 and Apple iOS 14 Devices Due to the Use of MAC Randomization on the Mobile Client Devices – Workaround Provided

        Problem Description
        Cisco Identity Services Engine (ISE) services that use MAC address lookup might fail with Android 10 and Apple iOS 14 devices due to the use of MAC address randomization on the mobile client devices, which could result in unexpected network connectivity disruption for these devices…

        Workaround/Solution
        There is currently no large scale solution for the issues introduced by third-party MAC address randomization, only workarounds are available.

        Note: It is possible to disable MAC address randomization at a per-device level. In order to do so, see the manufacturer’s documentation for the respective end user device.

        BYOD

        As a workaround for the BYOD flow, the MAC_in_SAN condition and BYOD_is_registered condition from the Employee_EAP-TLS authorization rule can be removed so that the MAC address is not compared when the device connects to the SSID with the certificate..
