Command Usage
• Private VLANs are used to restrict traffic to ports within the same community,
and channel traffic passing outside the community through promiscuous
ports. When using community VLANs, they must be mapped to an associated
“primary” VLAN that contains promiscuous ports.
• Port membership for private VLANs is static. Once a port has been assigned
to a private VLAN, it cannot be dynamically moved to another VLAN via GVRP.
• Private VLAN ports cannot be set to trunked mode. (See “switchport mode” on
page 4-301.)
