Private VLAN
A private VLAN helps to resolve the primary VLAN ID shortage, client ports' isolation and network security
issues. The private VLAN features provides primary and secondary VLANs within a single switch.
Primary VLAN: The uplink port is usually a member of the primary VLAN. A primary VLAN contains
promiscuous ports that can communicate with Secondary VLANs.
Secondary VLAN: The client ports are usually defined within secondary VLAN. The secondary VLAN includes
Isolated and Community VLANs. 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 cannot.
This figure shows a typical private VLAN network. A SCADA/Public Server or NMS workstation is usually
located in a primary VLAN. Client PCs and rings are usually located within the secondary VLAN.
