What is etsysNacApplContactLostSwitches?
A Counter64 that counts the configured switches the NAC Appliance has lost SNMP contact with. This is a direct infrastructure-health indicator: a nonzero or increasing value means the NAC can no longer manage or monitor those switch ports for access control. If this counter increases by 3 after a core switch reboot, an admin would check whether the NAC's SNMP community strings or connectivity to that switch's management interface need to be restored.
