        **What is PVLAN?**

        PVLAN (Private VLAN) is a VLAN technology that partitions a VLAN into smaller isolated sub-VLANs to provide layer 2 isolation between ports within the same VLAN.

        **Why is PVLAN useful?**

        PVLAN enhances security by preventing direct communication between devices on the same VLAN while still allowing shared access to common resources like gateways.

        **How it works?**

        PVLAN divides a VLAN into primary and secondary VLANs:
        - **Promiscuous ports** communicate with all other ports.
        - **Isolated ports** cannot communicate with any other ports except promiscuous.
        - **Community ports** can communicate with other ports within the same community VLAN and promiscuous ports.

        **Where is PVLAN used?**

        PVLAN is used in service provider networks, data centers, and shared hosting environments to isolate clients while maintaining shared infrastructure access.

        **Which OSI layer does PVLAN belong to?**

        PVLAN operates at Layer 2 (Data Link Layer) of the OSI model.

        **Is PVLAN Windows specific?**

        No, PVLAN is not Windows specific. It is a network switch feature implemented in network infrastructure devices.

        **Is PVLAN Linux specific?**

        No, PVLAN is not Linux specific. It depends on network hardware support, not the operating system.

        **Which Transport Protocol is used by PVLAN?**

        PVLAN does not use any transport protocol as it is a Layer 2 switching technology.

        **Which Port is used by PVLAN?**

        PVLAN does not use TCP/UDP ports since it operates at the Data Link Layer.

        **Is PVLAN using Client server model?**

        No, PVLAN is a switching mechanism and does not use a client-server model.
