Private VLANs must first be configured on the physical switch ports of the uplink NICs on the vDS. Private VLANs restrict this visibility and in essence act as firewalls within the VLAN. Normally, traffic on the same vSwitch port group has no restrictions and any VM in that port group can see the traffic from other VMs. This feature, which is normally available on physical switches, was added only to the vDS and not the standard vSwitch. Private VLANs allow communication between VMs on a vSwitch to be controlled and restricted. Implementation and benefits of private VLANs with a vSphere network Along with that come a new high-performance virtual NIC, VMXNET3, the ability to create private VLANs and support for IPv6. VMware’s vSphere 4 brings a number of new vSphere networking features to the table, including tighter VM traffic management and control with the vNetwork Distributed Switch (vDS), as well as support for third-party virtual switches (vSwitches). ![]()
