Description
Technical field
The invention belongs to communication technical field, particularly relate to the method based on the access point acquisition client mac address of multiple VLAN and device.
Background technology
At the thin AP (AccessPoint of employing, access point) and wireless AC (AccessController, access controller) WLAN (WirelessLocalAreaNetwork, WLAN (wireless local area network)) in solution, the user data of client is undertaken transmitting by VLAN (VirtualLocalAreaNetwork, VLAN).When the type of service of user data is more, generally need to divide multiple VLAN.In prior art, when multiple VLAN, if the application layer program run on thin AP wants the MAC (MediaAccessControl obtaining client, medium access control) address, usually obtained from ARP (AddressResolutionProtocol address resolution protocol) table by interface.But, if client does not carry out service communication, namely the user data of client is without the forwarding of thin AP, then there is not the IP (InternetProtocol of this client in ARP table, Internet protocol) corresponding relation of address and MAC Address, cause thin AP cannot obtain the MAC Address of client; If client does not carry out service communication for a long time, then aging due to ARP table, the IP address of this client and the corresponding relation of MAC Address can be deleted, cause thin AP cannot obtain the MAC Address of client.
To sum up, prior art is when multiple VLAN, and access point cannot obtain the MAC Address of client sometimes.
Summary of the invention
Given this, embodiments provide a kind of access point based on multiple VLAN and obtain the method for client mac address and device, to solve prior art when multiple VLAN, access point cannot obtain the problem of the MAC Address of client sometimes.
First aspect, embodiments provides a kind of method that access point based on multiple VLAN obtains client mac address, comprising:
When receiving the user data that client sends, from described user data, obtain the medium access control MAC Address of described client;
Obtain the contingency table prestored;
If inquire about the MAC Address less than described client in described contingency table, then obtain the Internet protocol IP address of described client, and added in described contingency table by the related information of the MAC Address of described client and IP address, and store the described contingency table after adding.
Second aspect, embodiments provides the device that a kind of access point based on multiple VLAN obtains client mac address, comprising:
First MAC Address acquiring unit, for when receiving the user data that client sends, obtains the medium access control MAC Address of described client from described user data;
Contingency table acquiring unit, for obtaining the contingency table prestored;
First contingency table processing unit, if for inquiring about the MAC Address less than described client in described contingency table, then obtain the Internet protocol IP address of described client, and added in described contingency table by the related information of the MAC Address of described client and IP address, and store the described contingency table after adding.
The beneficial effect that the embodiment of the present invention compared with prior art exists is: the embodiment of the present invention is by when receiving the user data that client sends, the MAC Address of client is obtained from user data, when inquiring about the MAC Address less than this client in contingency table, obtain the IP address of this client, and the related information of the MAC Address of this client and IP address is added in contingency table, thus achieve the access point when multiple VLAN and obtain the MAC Address of client, thus when multiple VLAN, avoid the MAC Address being obtained client by ARP table, solve the problem that the access point caused due to problems such as ARP table are aging cannot obtain the MAC Address of client.

The access point based on multiple VLAN that Fig. 1 shows the embodiment of the present invention to be provided obtains the realization flow figure of the method for client mac address, and details are as follows:
In step S101, when receiving the user data that client sends, from described user data, obtain the medium access control MAC Address of described client.
It should be noted that, the executive agent in the embodiment of the present invention can be thin AP.
In embodiments of the present invention, when client is online or reach the standard grade and receive that client sends out user data time, analyzing and processing is carried out to the Frame of user data, from the Frame of user data, extracts the MAC Address of client.Here, user data refers to the data that client sends.
In step s 102, the contingency table prestored is obtained.
As one embodiment of the present of invention, be associated table in the wireless network card of thin AP, contingency table is for the related information of the MAC Address and IP address that record the client accessing thin AP, here, the MAC Address of client and the related information of IP address refer to the MAC Address of client and the corresponding relation of IP address.
After acquisition contingency table, in inquiry contingency table, whether there is the MAC Address of client.
In step s 103, if inquire about the MAC Address less than described client in described contingency table, then obtain the Internet protocol IP address of described client, and the related information of the MAC Address of described client and IP address is added in described contingency table, and store the described contingency table after adding.
The embodiment of the present invention is by extracting the MAC Address of client the user data from client transmission and storing, achieve the MAC Address obtaining client when multiple VLAN, thus avoid obtaining the MAC Address of client by ARP table, solve the problem that the access point caused due to problems such as ARP table are aging cannot obtain the MAC Address of client.
The access point based on multiple VLAN that Fig. 2 shows another embodiment of the present invention to be provided obtains the realization flow figure of the method for client mac address, with reference to Fig. 2:
In step s 201, when receiving the user data that client sends, from described user data, the medium access control MAC Address of described client is obtained;
In step S202, obtain the contingency table prestored;
In step S203, if inquire about the MAC Address less than described client in described contingency table, then obtain the Internet protocol IP address of described client, and the related information of the MAC Address of described client and IP address is added in described contingency table, and store the described contingency table after adding;
In step S204, if inquire the MAC Address of described client in described contingency table, then described contingency table is not changed.
The access point based on multiple VLAN that Fig. 3 shows another embodiment of the present invention to be provided obtains the realization flow figure of the method for client mac address, with reference to Fig. 3:
