DACL not applying to switch port

Hey Team,

Having issues in pushing DACL to Cisco switch. On ISE, it shows Authentication succeeded but on switch it shows authz failed. We have properly applied COA on switch. As soon as we remove DACL and enforce vlan, everything starts to work.

Did anyone face the same issue before?

On switch, we see the following logs

@pavit-gulati is device tracking configured on the switch? Please provide the full configuration for review.

Does your dACL validate properly on ISE?  What is the NAD?

This issue solved ?
