I have a scenario whereby wireless clients are authenticated by the ISE and different ACLs are applied to it based on the rules on ISE. The problem I seems to be seeing is due to the limitation on the Cisco WLC which limit only 64 access-list entries. As the setup has only a few SVI/interfaces and multiple different access-lists are applied to the same interface base on the user groups; I was wondering if there may be a scalable design/approach whereby the access-list entries may scale beside creating a vlan for each user group and applying the access-list on the layer 3 interface instead? I have illustrated the setup below for reference:
User group 1 -- Apply ACL 1 --On Vlan 1
User group 2 -- Apply ACL 2 -- On Vlan 1
User group 3 -- Apply ACL 3 -- On Vlan 1
The problem is only seen for wireless users, it is not seen on wired users as the ACLs may be applied successfully without any limitation to the switches.
Apologies for the late reply and appreciate for the information. We have decided to make use of the L3 interface with minimum ACLs remaining on the wlc via the ise (guest acls/shared user-groups acls).
