community - A VLAN in which traffic is restricted to host

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 1349.)
