Community/Isolated Access Port

Community ports communicate among themselves and with their promiscuous ports and PVLAN member port. These ports are separated at Layer 2 from all other ports in other communities or isolated ports within their PVLAN.

Isolated ports have Layer 2 connectivity only with promiscuous ports and PVLAN member ports. An isolated access port cannot communicate with another isolated port even if the two ports are members of the same isolated VLAN.
