Multi-hop L3 support for out-of-band (wired) deployments enables administrators to deploy the CAS out-of-band centrally (in core or distribution layer) to support users behind L3 Switches (e.g. routed access) and remote users behind WAN routers in some instances. With L3 OOB, users more than one L3 hop away from the CAS are supported and their traffic only has to go through Cisco NAC Appliance for authentication/posture assessment only.
