during a HP (2920) Switching / NAC project i learned that MAC or 802.1x re-authentication can be done directly via switch CLI:
aaa port-access mac-based <[i][code]port-list
[code][code]aaa port-access authenticator
This is a nice feature especially you do not have Netsight NAC with NAC Managers "Force Re-auth" button.
In the past everybody uses a hard port link down/up - but the above command is smarter especially you have multi-user on that regarding port.
Is there a similar command for re-authentication available on EXOS / EOS ??
