Detailed Description
In view of the problems in the prior art, an embodiment of the present invention provides a method for transmitting configuration information, where the method may be applied to a WLAN including an AC and an AP, the AC and the AP are connected through one or more network devices, and the AC establishes a control tunnel and a data tunnel with the AP through a CAPWAP protocol. The control tunnel is used for transmitting a control message between the AC and the AP, and the data tunnel is used for transmitting a data message between the AC and the AP. Referring to fig. 1 as an application scenario schematic diagram of the embodiment of the present invention, as shown in fig. 1, an AC is connected to an AP3 through a network device 1, and a physical port on the network device 1, which is connected to an AP3, is a port a. The AC is connected to the AP1 through network device 1 and network device 2, and the physical port on network device 2 to which the AP1 is connected is port a. The AC is connected to the AP2 through network device 1 and network device 2, and the physical port on network device 2 to which the AP2 is connected is port b.
In the application scenario, as shown in fig. 2, the method for transmitting configuration information includes the following steps:
In this embodiment of the present invention, the identification information of the AP may specifically include, but is not limited to, a Media Access Control (MAC) address of the AP, or a MAC address of the AP and an AP type.
Each AP may be configured with an MAC address and an AP type when leaving the factory, and based on the factory configuration, the AP may obtain the MAC address of the AP (at this time, the AP types of the APs in the default WLAN are the same), or obtain the MAC address and the AP type of the AP.
The AP type of the AP is the model of the AP, the APs of the same AP type may use the same configuration information, the APs of different AP types may not use the same configuration information, and use different configuration information.
In this embodiment of the present invention, the location information of the AP may specifically include but is not limited to: the identification of the neighbor network device connected with the AP and the identification of the physical port connected with the AP on the neighbor network device.
Based on the location information, in the embodiment of the present invention, the process of the AP acquiring the location information of the AP may specifically include, but is not limited to, the following manners: the AP receives an LLDP (Link Layer discovery protocol) message sent by a neighbor network device connected to the AP, and obtains an identifier of the neighbor network device and an identifier of a physical port connected to the AP on the neighbor network device from the LLDP message.
As shown in fig. 1, the AP1 obtains the identifier of the neighbor network device (i.e., network device 2) from the LLDP message from the network device 2, and the identifier of the physical port (i.e., port a) connected to the AP1 on the neighbor network device, at this time, the AP1 obtains the identification information of the AP as MAC address 1 and AP type 1, and the location information is network device 2 and port a. Similarly, the AP2 obtains the identification information of the AP as MAC address 2 and AP type 1, and the location information is network device 2 and port b. The AP3 obtains the identification information of the AP as MAC address 3 and AP type 1, and the location information is network device 1 and port a. Assuming that the AP1 needs to be replaced due to damage or upgrade, and the user replaces the AP1 with the AP4 at the location of the AP1, the AP4 obtains the identification information of the AP as the MAC address 4 and the AP type 1, and the location information is the network device 2 and the port a.
In step 203, the AC receives a device information notification message carrying the identification information and the location information of the AP from the AP.
After the AC establishes a control tunnel and a data tunnel with the AP through a CAPWAP protocol, the AP can send the equipment information notification message carrying the identification information and the position information of the AP to the AC through the control tunnel, and the AC receives the equipment information notification message.
As shown in fig. 1, the AP1 sends a device information notification message carrying the MAC address 1, the AP type 1, the network device 2, and the port a to the AC. The AP2 sends a device information notification message carrying the MAC address 2, the AP type 1, the network device 2, and the port b to the AC. The AP3 sends a device information notification message carrying the MAC address 3, the AP type 1, the network device 1, and the port a to the AC. Under the condition that the AP4 replaces the AP1, the AP4 sends a device information notification message carrying the MAC address 4, the AP type 1, the network device 2, and the port a to the AC.
And step 204, the AC compares the identification information and the location information of the AP carried in the device information notification message with the AP identification information recorded in the local AP identification table and the AP location information corresponding to the AP identification information.
If the AP location information identical to the location information of the AP does not exist in the AP identification table, step 205 is performed; if the AP location information that is the same as the location information of the AP exists in the AP identification table, and the AP identification information corresponding to the AP location information is different from the AP identification information, step 206 is executed.
In step 205, the AC records the correspondence between the AP identification information carried in the device information notification message and the AP location information in the AP identification table.
After the AC records the corresponding relationship between the identification information of the AP and the position information of the AP carried in the device information notification message in the AP identification table, configuration information is issued to the AP corresponding to the identification information of the AP according to the existing flow.
In step 206, the AC determines that the AP that sends the device information notification packet replaces the AP corresponding to the AP identification information (i.e., the AP identification information corresponding to the AP location information), and replaces the AP identification information recorded in the AP identification table with the AP identification information carried in the device information notification packet.
In the embodiment of the present invention, when the identification information of the AP only includes the MAC address of the AP (at this time, the AP type of each AP in the default WLAN is the same), the difference between the AP identification information corresponding to the AP location information and the identification information of the AP means: the MAC address corresponding to the AP position information is different from the MAC address of the AP; when the identification information of the AP includes the MAC address and the AP type of the AP, the difference between the AP identification information corresponding to the AP location information and the AP identification information means: the MAC address corresponding to the AP position information is different from the MAC address of the AP, and the AP type corresponding to the AP position information is the same as the AP type of the AP. For convenience of description, the following example that the identification information of the AP includes the MAC address of the AP and the AP type is taken, and details are not repeated for the case that the identification information of the AP only includes the MAC address of the AP.
In the embodiment of the present invention, the AP identification table is used to record the corresponding relationship between the MAC address, the AP type, the identifier of the neighbor network device, and the physical port identifier, and is an initial AP identification table as shown in table 1 below.
TABLE 1
| MAC address | AP type | Identification of neighbor network devices | Physical port identification |
After receiving the device information notification message carrying the MAC address 1, the AP type 1, the network device 2, and the port a, the AC queries the AP identifier table shown in table 1 according to the device information notification message,
since there is no corresponding record, the correspondence between the MAC address 1, the AP type 1, the network device 2 and the port a carried in the device information notification message is recorded in the AP identification table, as shown in table 2 below.
TABLE 2
| MAC address | AP type | Identification of neighbor network devices | Physical port identification |
| MAC Address 1 | AP type 1 | Network device 2 | Port a |
After receiving the device information notification message carrying the MAC address 2, the AP type 1, the network device 2, and the port b, the AC queries the AP identifier table shown in the table 2 according to the device information notification message, and records the correspondence between the MAC address 2, the AP type 1, the network device 2, and the port b carried in the device information notification message in the AP identifier table because there is no corresponding record, as shown in table 3 below.
TABLE 3
| MAC address | AP type | Identification of neighbor network devices | Physical port identification |
| MAC Address 1 | AP type 1 | Network device 2 | Port a |
| MAC Address 2 | AP type 1 | Network device 2 | Port b |
After receiving the device information notification message carrying the MAC address 3, the AP type 1, the network device 1, and the port a, the AC queries the AP identifier table shown in the table 3 according to the device information notification message, and records the correspondence between the MAC address 3, the AP type 1, the network device 1, and the port a carried in the device information notification message in the AP identifier table because there is no corresponding record, as shown in table 4 below.
TABLE 4
| MAC address | AP type | Identification of neighbor network devices | Physical port identification |
| MAC Address 1 | AP type 1 | Network device 2 | Port a |
| MAC Address 2 | AP type 1 | Network device 2 | Port b |
| MAC Address 3 | AP type 1 | Network device 1 | Port a |
After receiving the device information notification message carrying the MAC address 4, the AP type 1, the network device 2, and the port a, the AC queries the AP identifier table shown in the table 4 according to the device information notification message, finds that an AP (i.e., AP1) exists in the identifier table, where other information (i.e., the AP type, the identifier of the neighbor network device, and the physical port identifier) is the same except that the MAC address of the AP is different, which indicates that the AP4 corresponding to the MAC address 4 replaces the AP1, at this time, sends the configuration information of the AP1 to the AP4 (i.e., the AP currently sending the device information notification message), and replaces the MAC address 1 in the AP identifier table with the MAC address 4 carried in the device information notification message, as shown in table 5 below.
TABLE 5
| MAC address | AP type | Identification of neighbor network devices | Physical port identification |
| MAC Address 4 | AP type 1 | Network device 2 | Port a |
| MAC Address 2 | AP type 1 | Network device 2 | Port b |
| MAC Address 3 | AP type 1 | Network device 1 | Port a |
Further, in this embodiment of the present invention, after the AC sends the configuration information to the AP, the AP may receive the configuration information from the AC, and complete its configuration based on the configuration information. Wherein, the AC may issue the configuration information to the AP based on the control tunnel. As shown in fig. 1, when the AP1 needs to be replaced due to damage or upgrade, the user may unplug the AP1 at the location of the AP1 and then insert the AP4 in situ. In this case, the AC may transmit the configuration information of the AP1 to the AP4, complete its configuration by the AP4 using the configuration information of the AP1, thereby completing the configuration quickly and operating the service quickly.
Based on the above technical solution, in the embodiment of the present invention, when the original AP needs to be replaced due to damage or upgrade, and after the user replaces the new AP at the location of the original AP, if the location information corresponding to the original AP is the same as the location information corresponding to the new AP and the identification information corresponding to the original AP is different from the identification information corresponding to the new AP, the AC may automatically issue the configuration information of the original AP to the new AP, and the new AP completes its own configuration by using the configuration information. In the process, the user does not need to manually reconfigure the configuration information of the new AP on the AC, thereby saving a great deal of labor and time and avoiding configuring wrong configuration information.
