PVLANs divide the broadcast domain into multiple broadcast sub-domains and allow further isolating different devices within the same VLAN. They provide layer 2 isolation between ports within the same broadcast domain. For example: "Your ESXi host uses several networks. Use appropriate security measures for each network, and isolate traffic for specific applications and functions. For example, ensure that VMware vSphere vMotion traffic does not travel over networks where virtual machines are located. Isolation prevents snooping. Having separate networks is also recommended for performance reasons."
