摘要
FIELD: physics, computer engineering.;SUBSTANCE: invention relates to means of accessing a VPN service for a multiport Ethernet interface device. The method includes detecting, by the multi-port Ethernet interface device, a corresponding internal control VLAN according to information of a VPN service access mode, in-port information of a VPN service message and a preset mapping table; wherein said preset mapping table includes a one-to-one correspondence linear relationship between ports of the multi-port Ethernet interface device and internal control VLAN; writing the internal control VLAN identifier into the VPN service message; sending the VPN service message with the written internal control VLAN therein to a switch chip or a network processor (NP) of a network device so that the switch chip or the NP can access a VPN service according to the internal control VLAN and a cascade port which is a port of the switch chip or the NP corresponding to the multiport Ethernet interface device.;EFFECT: providing access to a VPN service of a multiport Ethernet interface device.;11 cl, 6 dwg
