Chapter 3: Configuration

3.10.5 Private VLANs

In a private VLAN, communication between ports is not permitted. A VLAN can be configured as a private VLAN.

Assigning Membership in Private VLANs

The Private VLAN membership configurations for the switch can be monitored and modified here. Private VLANs can be added or
deleted here. Port members of each Private VLAN can be added or removed here. Private VLANs are based on the source port
mask, and there are no connections to VLANs. This means that VLAN IDs and Private VLAN IDs can be identical. A port must be a
member of both a VLAN and a Private VLAN to be able to forward packets. By default, all ports are VLAN unaware and members
of VLAN 1 and Private VLAN 1. A VLAN unaware port can only be a member of one VLAN, but it can be a member of multiple
Private VLANs.
