摘要

1. A method for accessing a virtual private network service (VPN) to a multiport Ethernet interface device, comprising: detecting respective internal control by multiport Ethernet VLAN interface devices in accordance with information about the access mode VPN service, the input port information and VPN services predefined message conversion table, record the internal management VLAN VPN service in the message; iotpravku VPN communication services recorded in his internal management VLAN on the switch chip or network processor (NP) of the network device to the switch chip or NP could gain access to a VPN service in accordance with the internal management VLAN, and the cascade port, while the uplink port is port NP chip or switch in accordance with a multiport device Ethernet.2 interface. A method according to claim 1, characterized in that the detection of corresponding internal control by multiport Ethernet VLAN interface devices in accordance with information about access to the VPN service mode, the input port information of the VPN service message and a predetermined conversion table comprises: detecting a corresponding internal control in VLAN according to the input port information and communication VPN service conversion table, if the mode of access to the VPN service is an access mode through port.3. A method according to claim 2, characterized in that the detection of corresponding inner VLAN management in accordance with the input port information and VPN services message conversion table includes: extracting information about the input port VPN service message; iobnaruzhenie appropriate internal
