发明名称 Connecting a PVLAN switch to a non-PVLAN device
摘要 A PVLAN switch for connecting a PVLAN to a non-PVLAN device is configured as a primary VLAN with secondary VLANs, the primary VLAN includes promiscuous ports, each of the secondary VLANs includes a smart PVLAN trunk port, and the smart PVLAN trunk port is included in at least two secondary VLANs where the smart PVLAN trunk port and the promiscuous port connect to non-PVLAN devices. A frame is received on a smart PVLAN trunk port sent from a non-PVLAN device, and includes a destination address and a secondary VLAN ID. The PVLAN switch port ID for the first frame, and a primary VLAN ID for the secondary VLAN ID are identified. If the frame is a non-isolated port, the secondary VLAN ID is modified to be the primary VLAN ID, and the modified frame is sent to another non-PVLAN device connected to the PVLAN switch port.

主权项 1. A method of connecting a private virtual local area network PVLAN switch to a non-PVLAN device, wherein the PVLAN switch is configured as a primary VLAN with at least two secondary VLANs related to the primary VLAN, the primary VLAN includes at least one promiscuous port, each of the at least two secondary VLANs includes at least one smart PVLAN trunk port, and the at least one smart PVLAN trunk port is included in at least two secondary VLANs wherein the smart PVLAN trunk port and the promiscuous port are for connecting non-PVLAN devices, the method comprising: receiving a first frame on a smart PVLAN trunk port sent from a non-PVLAN device connected to the smart PVLAN trunk port, the first frame including a destination address and a secondary VLAN ID; identifying, based on the destination address of the first frame, the PVLAN switch port ID corresponding to the first frame, and the primary VLAN ID related to the secondary VLAN ID; in response to determining that the PVLAN switch port corresponding to the first frame is a non-isolated port: modifying the secondary VLAN ID in the first frame to be the primary VLAN ID related to the secondary VLAN; and sending the modified first frame to another non-PVLAN device connected to the PVLAN switch port corresponding to the first frame from the PVLAN switch port corresponding to the first frame.
