With Nexus 1000v 1.4 release, Cisco has introduced a new feature vPath. It offers the ability to run virtualized services . In case of VSG, it perform multiple functions:

- intelligent steering of traffic to the firewall node (VSG) for policy evaluation.

- The result is cached in the vPath flow table

- Firewall policy enforcement is done  via the vPath.

- vPath is multitennat aware. The traffic is redirected to the tenant VSG based on the flow destination

- vPath provides dynamic policy provisioning to new VMs coming on to the network

- The architecture allows to decouple service from the workload

- Performance is enahnced since the process has been offloaded from VM level processing to Hypervisor

There are some new videos posted on the community site which can help you install and configure the VSG/VNMC solution. If you want to look at a quick demo to see how the security policy enforcement is done for a tenant, please check out this video VSG/VNMC Demo
