For private VLANs to be applied, the switch must first be configured for standard VLAN
operation. When this is in place, one or more of the configured VLANs can be
configured as private VLANs. Ports in a private VLAN fall into one of these two groups:
Promiscuous ports
• Ports from which traffic can be forwarded to all ports in the private VLAN.
• Ports that can receive traffic from all ports in the private VLAN.
Isolated ports
• Ports from which traffic can only be forwarded to promiscuous ports in the private
VLAN.
• Ports that can receive traffic from only promiscuous ports in the private VLAN.
The configuration of promiscuous and isolated ports applies to all private VLANs. When
traffic comes in on a promiscuous port in a private VLAN, the VLAN mask from the
VLAN table is applied. When traffic comes in on an isolated port, the private VLAN
mask is applied in addition to the VLAN mask from the VLAN table. This reduces the
ports to which forwarding can be done to just the promiscuous ports within the private
VLAN.
The Port Isolation Configuration page is used for enabling or disabling port isolation on
ports in a private VLAN. A port member of a VLAN can be isolated to other isolated
ports on the same VLAN and private VLAN.
