Private VLAN
The private VLAN helps to resolve the primary VLAN ID shortage, client ports’ isolation and
network security issues. The Private VLAN provides primary and secondary VLAN within a
single switch.
Primary VLAN:
The uplink port is usually the primary VLAN. A primary VLAN contains
promiscuous ports that can communicate with lower Secondary VLANs.
Secondary VLAN:
The client ports are usually defined within secondary VLAN. The
secondary VLAN includes Isolated VLAN and Community VLAN. The client ports can be
isolated VLANs or can be grouped in the same Community VLAN. The ports within the
same community VLAN can communicate with each other. However, the isolated VLAN
ports can Not.
The figure shows the typical Private VLAN network. The SCADA/Public Server or NMS
workstation is usually located in primary VLAN. The clients PCs or Rings are located within
Secondary.
