Description (partial)

Port goes into unauthorized state when DACLs of a certain length are pushed to the 4500 as a result of successful client authentication.

A standard numbered ACL is defined on the 4500 with (the length of the name of the DACL pushed from ISE) as the number.
For example:
If the DACL being pushed is xACSACLx-IP-ABCD1234-aabbccdd, and there is a numbered ACL with the number 29 on the switch "access-list 29 permit host", then this DACL will trigger the port to go into the unauthorized state.
