The corresponding VLAN ID vlanid of data, and the VLAN ID vlanid is added to the data, from
It and can will include that the data identified are accurately sent to target position, and can reduce the package operation to data.
In step s 102, when receiving the data of upper layer network transmission, received data are parsed to obtain void
Quasi- LAN ID vlanid, and forwarded the data on according to the VLAN ID vlanid to corresponding port.
When receiving the data sent by upper layer network, need to parse the target position of data, root of the present invention
It parses to obtain VLAN ID vlanid according to received data, according to the preset VLAN ID and port
Corresponding relationship, to forward the data to corresponding port.
For example, can be parsed to obtain source physical MAC address and network card equipment title according to data, according to network card equipment name
Claim and source physical MAC address, in conjunction with preset corresponding relationship, port corresponding to available data, thus by data into
Row separation.

In embodiments of the present invention, wired network card apparatus title is preset, for example, the preset network card equipment title
It can be Eth1, then the identification of wired network interface can be rapidly performed by by the comparison of network card equipment title.
In step S203, if the source network card equipment title is identical with preset network card equipment title, the void
Quasi- LAN ID vlanid is wireline interface VLAN ID vlanid.
Since the title for presetting all wired network adapters is identical, then, if network card equipment title is identified as presetting
Selected title then can quickly identify wired network interface.
By the identification to wired network adapter title, it can overcome and wire user and wireless user are carried out in the prior art
Identify difficult problem.In the prior art, the data of the wired mouth and wireless mouth that are connected for thin access point are all unified
Forwarding also brings many inconvenience to management in this way, if we will extract wireless user, must just pick inside user list
Except wire user, wireless user is obtained with this, furthermore, current fitAP equipment at least one general wireless access point, greatly
Majority all concentrates between 2-10 wireless access point, and it is just more difficult to separate different access point users in this way.And it is of the invention
By the identification of network card equipment title, wireline interface can be quickly identified.
For example, if the preset entitled Eth1 of source network card equipment, when the network card equipment for parsing the equipment is entitled
It is then that can determine that the interface is the vlanid of wired mouthful of Eth1 according to the network card equipment title when Eth1.
In step S204, if the source network card equipment title is different with preset network card equipment title, according to institute
It states source MAC and searches corresponding wireless interface, corresponding VLAN ID vlanid is determined according to the wireless interface.
If comparing to obtain network card equipment title different from preset network card equipment title, then it represents that current interface is wireless
Interface then needs further to be further determined that according to the corresponding relationship of the source address mac and VLAN ID vlanid wireless
The VLAN ID vlanid of interface.The i.e. different source addresses mac correspond to different VLAN ID vlanid.From
And different wireless interfaces can be distinguished.
In the virtual local area network mark for the VLAN ID vlanid and different wireless interfaces for distinguishing wireline interface
Know vlanid, further include the steps that data are further added VLAN ID vlanid, comprising:
In data storage area, the data are elapsed backward, is obtained before the data storage location of data storage area
