Meraki MS switches do not support traditional redirect ACLs like Cisco IOS switches. Instead, Meraki uses a "walled garden" approach.   Meraki does honor the url-redirect attribute returned by ISE in the RADIUS Access-Accept message. This is used to redirect the client to the ISE posture portal.   Meraki does not support Cisco-style dACLs. Instead, it uses Group Policies.   Refer the documentation. "These steps show how to configure ISE Authorization policy for wired employee access using 802.1X as well as supporting wired guest users with the hotspot portal.  Just like Meraki Wireless platforms, Meraki switches now support advanced use cases such as MDM enrollment, Native Supplicant Provisioning (BYOD) and posture assessment.  Please see the wireless section for information on how to configure these advanced uses cases."   https://community.cisco.com/t5/security-knowledge-base/how-to-integrate-meraki-networks-with-ise/ta-p/3618650 ...
