Clearpass deploys dACL to Cisco switches

    Hi Guys,
    There is a question that needs your help. Now I've deployed dACL to Cisco switches via Clearpass, such as permit ip any host, and enabled IP device tracking in Cisco switches. However, the ACL applied by the switch to the interface does not replace "any" with the IP address obtained by the host under the interface. I'm confused about that. I've deployed ISE before, and the switch replaces the "any" in the ACL obtained from ISE with the specific address. So, is this a compatibility issue with Clearpass and Cisco or is there a misconfiguration?

    If you apply the ACL to a specific client (MAC), there is no real difference unless the client changes its IP address. I'm not aware of such replacement of any by the IP address, and if you still have your ISE available you could do a packet capture on the RADIUS traffic and compare what ClearPass sends differently if you want to change this behavior.
