vPath also provides performance advantages. Since only the initial packets of a flow need to go to the VSG, there is less packet steering going on. Subsequent policy enforcement is done by the local N1KV VEM in the kernel mode, so you get better performance overall.

HA is available, but if the service that vPath is directing to fails (for example, in the case of a firewall service where both firewalls are down), there is the option of failing closed or open. It can stop all traffic, or can be configured to let everything through.
