Untagged Port: - **Outgoing Traffic**: Frames leaving the port are sent without VLAN tags. - **Usage**: For devices that do not support VLAN tagging (e.g., PCs, printers). - **Example**: If port 1 is untagged for VLAN 10, outgoing traffic is untagged and associated with VLAN 10. **PVID (Port VLAN Identifier):** - **Incoming Traffic**: Assigns a VLAN ID to untagged frames entering the port. - **Usage**: Ensures untagged incoming traffic is correctly identified with a VLAN. - **Example**: If port 1 has a PVID of 10, incoming untagged frames are tagged with VLAN 10. ### Configuration Example: To set port 1 for VLAN 10: 1. **Set Port 1 as Untagged for VLAN 10**: Outgoing frames are untagged. 2. **Set PVID of Port 1 to 10**: Incoming untagged frames are tagged with VLAN 10. ### Summary: - **Untagged**: Controls outgoing traffic tagging. - **PVID**: Controls incoming traffic tagging.
