Cisco ASA 5500 Series Configuration Guide using ASDM
70-12
Hold-off—Number of peers for which the adaptive security appliance lost EAPoUDP
communications after a successful posture validation. The NAC Hold Timer attribute (Configuration
> VPN > NAC) determines the delay between this type of event and the next posture validation
attempt.
N/A—Number of peers for which NAC is disabled according to the VPN NAC group policy.
Revalidate All—Click if the posture of the peers or the assigned access policies (that is, the
downloaded ACLs), have changed. Clicking this button initiates new, unconditional posture
validations of all NAC sessions managed by the adaptive security appliance. The posture validation
and assigned access policy that were in effect for each session before you clicked this button remain
in effect until the new posture validation succeeds or fails. Clicking this button does not affect
sessions that are exempt from posture validation.
Initialize All—Click if the posture of the peers or the assigned access policies (that is, the
downloaded ACLs) have changed, and you want to clear the resources assigned to the sessions.
Clicking this button purges the EAPoUDP associations and assigned access policies used for posture
validations of all NAC sessions managed by the adaptive security appliance, and initiates new,
unconditional posture validations. The NAC default ACL is effective during the revalidations, so the
session initializations can disrupt user traffic. Clicking this button does not affect sessions that are
exempt from posture validation.
