Is there away to stop the port from reauthenticating when a device fails to open. I am trying to set up low-impact mode on a wired network. And I have some WYSE terminals that I don't want to authenticate to the network so I would like them to fail open with an ACL limiting their access. However the switch continues to try and authenticate the device even after it has failed authentication. This is causing my logs on ISE to be full of bogus authentication failures. Is there a way to limit thoses errors or the the switchport from trying to reauthenticate? Below is the switchport config.
switchport access vlan 33
switchport mode access
switchport voice vlan 233
ip access-group ACL-DEFAULT in
authentication event fail retry 1 action next-method
authentication event server dead action authorize vlan 33
authentication event server alive action reinitialize
authentication host-mode multi-auth
authentication open
authentication order dot1x mab
authentication priority dot1x mab
authentication port-control auto
authentication timer reauthenticate server
authentication violation restrict
mab
dot1x pae authenticator
dot1x timeout tx-period 10
spanning-tree portfast

Hi Nicolas,
You can configure a Restricted VLAN using the command "authentication event fail action authorize vlan (number)" and limit the access for that vlan using ACLs.
You can refer to

Perfect. I thought that would fail it from trying to do MAB. But it still runs through the order and then fails back to the VLAN.
