Chapter P Commands
A community VLAN is defined as the VLAN that carries the traffic among community ports and from
community ports to the promiscuous ports on the corresponding primary VLAN.
A primary VLAN is defined as the VLAN that is used to convey the traffic from the routers to customer
end stations on private ports.
Multiple community and isolated VLANs are allowed. If you enter a range of primary VLANs, the
system uses the first number in the range for the association.
If VLAN Trunking Protocol (VTP) is enabled on a switch, you can configure private VLANs only on a
device configured in Transparent mode.
