Hi. I'm running ISE 2.2 and 3850 switches with IBNS configuration. I'm unclear as to the functioning of the preauth_ipv4_acl.
When exactly is this in effect?
Is it applied automatically or only when I somehow configure it?
Is it still in effect pre-authentication when I configure access-session closed?
If Authentication fails is it still in effect?
Is there a command I can run to see whether it's currently in effect on an interface?
Where can I find good documentation on how this ACL functions?
Any clues appreciated.
