Command Usage
• Private VLANs are used to restrict traffic to ports within the same
VLAN “community,” and channel traffic passing outside the
community through promiscuous ports that have been mapped to the
associated “primary” VLAN.
• 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 4-202.)
