A private VLAN partitions a traditional VLAN into subdomains identified by a primary and secondary VLAN pair. The FTOS private VLAN implementation is based on RFC 3069. Private VLAN Concepts Primary VLAN: The primary VLAN is the base VLAN and can have multiple secondary VLANs. There are two types of secondary VLAN - community VLAN and isolated VLAN: • A primary VLAN can have any number of community VLANs and isolated VLANs. • Private VLANs block all traffic to isolated ports except traffic from promiscuous ports. Traffic received from an isolated port is forwarded only to promiscuous ports or trunk ports. Community VLAN: Private VLAN (PVLAN) | 711
