vsm# Example 9-22 shows how to configure the port-profiles on the Nexus 1000v for the VSG Communication. Example 9-22. Create the Cisco VSG Port-Profiles on the Nexus 1000v VSM. Port- Profile “VSG” Is the Data VLAN Click here to view code image vsm(config)# port-profile VSG vsm(config-port-prof)# vmware port-group vsm(config-port-prof)# switchport mode access vsm(config-port-prof)# switchport access vlan 102 vsm(config-port-prof)# no shutdown vsm(config-port-prof)# state enabled vsm(config-port-prof)# vsm(config)# port-profile VSG-HA vsm(config-port-prof)# vmware port-group vsm(config-port-prof)# switchport mode access vsm(config-port-prof)# switchport access vlan 102 vsm(config-port-prof)# no shutdown vsm(config-port-prof)# state enabled vsm(config-port-prof)# exit vsm(config)# Example 9-23 shows how to configure the port-profiles on the Nexus 1000v for the VSG Communication. Example 9-23. Do No Forget to Add the VSG-Data and HA VLANs to the Ethernet Profile. This Example uses “uplink” port-profile Click here to view code image vsm(config)# port-profile type ethernet uplink vsm(config-port-prof)# switchport trunk allowed vlan add 100, 200 vsm(config-port-prof)# exit Virtual Security Gateway Virtual Security Gateway (VSG) is a multitenant security firewall to secure virtualized
workloads. Deployment of virtualized workloads enables mobility between rack and rows within a data center and across a data center. The VSG security policy moves with the mobile virtualized workloads. With the VSG, workloads can be monitored and conform to compliance and regulatory regulations with the enterprise/cloud deployment. VSG secures virtualized environments by decoupling the control-plane and data-plane operations to leverage capabilities built into the VEM deployed in the ESX/ESXi Hypervisor. vPath is embedded in the 1000v VEM distributed virtual switch; VSG leverages vPath to steer the traffic to provide highly available, scalable tenant-aware security architecture. Because VSG is multitenant-aware, vPath can steer different traffic flows for client-server communication and server-server communication. VSG scales in many ways; for example, only the initial packet is sent to the VSG for policy enforcements. The policy will either permit or deny the traffic. The response to the initial packet, permit or deny, is offloaded directly to vPath on the VEM. In addition, VSG scales to provide security policy across multiple servers within the infrastructure with a centralized instance of VSG. vPath supports both Layer 2 and Layer 3. For Layer 2, the vPath encapsulation is Mac-in-Mac Layer 2 encapsulation. For Layer 3, the vPATH encapsulation is MAC-in-UDP Tunnel. vPath offers the following benefits: • Granular enforcement of network, security, and operational policies. • vPath support for multitennant deployment. • Offload policy and enables data-plane acceleration for services scale. • Enables virtual machine mobility to have policy follow the movement of each workload. • vPath 2.0 enables services chaining. vPath 2.0 service chaining enables two services to be chained with the first release. vPath 2.0 enables VSG and vASA security services to be chained. The chaining configured enables the sequence mode of operation—for example, which service is first. vASA enables edge firewall services that are not provided by VSG, such as Network Address Translation (NAT) and IP Security (IPsec). VSG offers flexible deployment options including both Layer 2 and Layer 3 deployment configuration. The Layer 2 or Layer 3 configuration refers to the communication between the VEM and the VSG Firewall. VSG can be placed on a dedicated appliance (Nexus 1010 or 1010-X) as an OVF or as a virtual machine on a traditional vSphere Guest to meet security requirements. VSG deployed on the Nexus 1010 as a VSB for VSG is covered in this section. VSG supports a traditional 5-tuple (Source IP address, Source port, Destination IP address, Destination port, and Protocol) security policy. VSG also supports a security model to decouple VLAN and IP address information from the security policy. The security administrator can define policy based upon the following schema attributes from vCenter: • Name of the virtual machine • Name of the ESX Host
