HP FlexFabric Virtual Switch 5900v Technology White Paper

5.
The physical switch does the following:
{ Requests network policy configurations for the VSI type from IMC through HTTP or HTTPS.
{ Applies the configurations to the ports.
6. After receiving the data, the VFE searches the local OpenFlow flow entries for the destination port
for data forwarding. If no port is matched, it forwards the data to the VCE component, which
determines the forwarding policy and destination port.
7. When a VM migrates, the physical switch does the following:
{ Obtains the network policies from the NMS according to VM and VSI type information
obtained through VDP.
{ Deploys the network policies to the VSI.

Port-group based VM connections
A port group in the 5900v virtual switch is defined as a group of network policy attributes, such as VLAN,
PVLAN, VEPA, and link aggregation. A port group allows for defining the same network policies for VMs
in the same service, and applying the port group to the virtual NICs on the VMs through VMware vCenter
Server. If a network policy in the port group changes, the new policy takes effect immediately without VM
reboot. Service continuity and high availability of the system are ensured in this way.
