User Guidelines
A community VLAN carries traffic among community ports and from
community ports to the promiscuous ports on the corresponding primary
VLAN.
An isolated VLAN is used by isolated ports to communicate with
promiscuous ports. It does not carry traffic to other community ports or other
isolated ports with the same primary VLAN.
The primary VLAN is the VLAN that carries traffic from a promiscuous port
to the private ports.
VLAN 1 cannot be configured in a private VLAN configuration.
