Configuring Private VLANs

Secondary VLANs

private VLAN can have multiple VLAN pairs, one pair for each subdomain. All VLAN pairs in a private VLAN share the same primary VLAN. The secondary VLAN ID differentiates one subdomain from another.

Secondary VLANs

There are two types of secondary VLANs:

•Isolated VLANs—Ports within an isolated VLAN cannot communicate with each other at the Layer 2 level.

•Community VLANs—Ports within a community VLAN can communicate with each other but cannot communicate with ports in other communities at the Layer 2 level.

Private VLANs Ports

Private VLANs provide Layer 2 isolation between ports within the same private VLAN. Private VLAN ports are access ports that are one of these types:
