Description

Access point management

This application claims the priority of a Chinese patent application filed with the Chinese Patent Office on September 27, 2018, with application number 201811135629.1 and entitled "A Method and Device for Managing APs", the entire contents of which are incorporated herein by reference. .

Background technique

With the widespread application of wireless local area networks (English: Wireless Local Area Network, WLAN for short), the scale of WLANs is also getting larger and larger. WLAN usually includes access controller (English: Access Controller, AC for short), power over Ethernet (English: Power over Ethernet, POE for short) switches and access points (English: Access Point, AP for short), AC Connect to the AP through the POE switch. Among them, the POE switch is used to power the AP, and the AC is used to manage the AP.

In a WLAN, when an AP is started, the administrator needs to configure the AP on the AC. The specific process is to create an AP template for the AP and set the attribute information corresponding to the AP in the AP template, such as the model of the AP. And serial number. Managers can then bind the AP template to a pre-configured service template. The service template includes working parameter information required by the AP to provide wireless access services, such as a service set identifier and a channel. In this way, when the AP starts, the AP can send an association request message to the AC. The association request message may carry the model and serial number of the AP. The AC can match the model and serial number of the AP carried in the association request with the attribute information in the AP template. If the match is successful, the AP is allowed to associate. Subsequently, the AC may send corresponding working parameter information to the AP according to the service template bound to the AP template, so that the AP provides wireless access services according to the working parameter information.

detailed description

In the following, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

In the prior art, a manager needs to configure an AP on the AC so that the AP can provide wireless access services. When an AP in a WLAN fails and needs to be replaced by a new AP, the administrator needs to configure the new AP on the AC so that the new AP can provide wireless access services. However, when the scale of a WLAN is large, the probability of failure of the APs in the WLAN is also large. In this way, each time a faulty AP is replaced with a new AP, corresponding configuration needs to be performed on the AC, resulting in low maintenance efficiency.

In order to solve the foregoing problem, an embodiment of the present application provides an AP management method, which can be implemented by an AC and an AP in a WLAN. As shown in FIG. 1, FIG. 1 is a system framework diagram provided by an embodiment of the present application. A WLAN generally includes an AC, a switch, an AP, and a terminal. The AC can be connected to the AP through a switch to perform association management and configuration management on the AP; the AP can be used to provide wireless access services for the terminal. The AC and AP can communicate through the CAPWAP protocol. The switch may be a POE switch, or may be another type of switch, which is not limited in the embodiment of the present application.

The following will describe in detail the processing process when the AC executes the AP management method described above in combination with specific embodiments, as shown in FIG. 2, and the specific steps are as follows.

Step 201: Receive a first communication message sent by a target AP.

The first communication packet may carry the model of the target AP (that is, the target model), the serial number (that is, the target serial number), and the MAC address of the target directly connected port obtained by the target AP. The port directly connected to the target AP.

In implementation, after the target AP is started, the target AP can obtain the MAC address of a port directly connected to the target AP on the switch through a link layer discovery protocol (English: Link Layer Discovery Protocol (LLDP)). Then, the target AP may send a first communication packet to the AC. The first communication message may carry a target model, a target serial number, and a MAC address of a target directly connected port obtained by the target AP. After receiving the first communication message sent by the target AP, the AC can parse the first communication message to obtain the target model, target serial number, and target obtained by the target AP carried in the first communication message. MAC address of the directly connected port.

Optionally, the first communication message may be a discovery request message (ie, a Discovery Request message) or a join request message (ie, a Join Request message). The embodiment of the present application is described by using the first communication message as a discovery request message as an example. Correspondingly, after the target AP obtains the MAC address of the target directly connected port, it can add the MAC address, target model, and target serial number of the target directly connected port to the discovery request message, and then send the discovery request message to the AC. Text. The discovery request message carries the target model, target serial number, and MAC address of the target directly connected port of the target AP. After receiving the discovery request message sent by the target AP, the AC can parse the discovery request message to obtain the target model, target serial number, and MAC address of the directly connected port of the target AP carried in the discovery request message. The situation in which the first communication message is a join request message is similar, and details are not described in the embodiment of the present application.

The target AP may carry the MAC address of the target directly connected port by adding a Type Length Value (English: Type, Value, TLV) field to the discovery request message.

Step 202: Query the working parameter information corresponding to the target model and the target serial number in a pre-stored AP information table.

Step 202 is to query the working parameter information corresponding to the target model and target serial number in the AP information table stored in advance as the first working parameter information.

The AP information table includes the correspondence between the AP model, serial number, MAC address of the directly connected port, and working parameter information.

In implementation, the AP information table may be stored in the AC in advance. The AP information table may include fields such as the AP model, serial number, MAC address of directly connected ports, and working parameter information. Among them, the working parameter information can provide parameter information required by the AP set in the service template to provide wireless access services, such as a service set identifier (English: Service Set Identifier, SSID for short), channel (Channel) and maximum power (Max_Power) Wait. The AP's model, serial number, and working parameter information can be configured by the management staff; the MAC address of the directly connected port can be configured by the management staff, or according to the first communication packet sent by the AP (such as a discovery request message or a join request Message). The specific process for the AC to determine the MAC address of the directly connected port according to the first communication packet sent by the AP will be described later, and will not be described in detail here.

For example, Table 1 is an example of an AP information table provided in the embodiment of the present application. The model of AP1 is A, the serial number is 123, and the MAC address of the directly connected port is 00-00-00-00-00-01. The SSID in the parameter information is X; the channel is 1; the maximum power is 20. The model of AP2 is A, the serial number is 456, the MAC address of the directly connected port is 00-00-00-00-00-02, the SSID in the working parameter information is Y; Channel is 6; Max_Power is 20. The model of AP3 is A, the serial number is 789, the MAC address of the directly connected port is empty, the SSID in the working parameter information is Z; Channel is 11; Max_Power is 20.

Table I

After the AC obtains the target model, target serial number, and MAC address of the directly connected port of the target AP carried in the discovery request message, it can query the first working parameter corresponding to the target model and target serial number in the AP information table. information. If the first working parameter information does not exist in the AP information table, the AC performs step 203. If the first working parameter information exists in the AP information table, the AC may not process it.

Step 203: If the working parameter information corresponding to the target model and the target serial number does not exist in the AP information table, query the working parameter information corresponding to the target model and the MAC address of the target directly connected port in the AP information table.

Step 203 is: if the first working parameter information does not exist in the AP information table, query the working parameter information corresponding to the target model and the MAC address of the target directly connected port in the AP information table as the second working parameter information.

In the implementation, if the first working parameter information does not exist in the AP information table, it means that the target AP is not the AP that was originally online, that is, it is determined that the target AP is a newly enabled AP. Among them, the newly enabled AP may be a replacement AP of the original AP or a newly launched AP. The replacement AP model of the original AP must be the same as the original AP model. In addition, for the replacement AP of the original AP, if the port directly connected to the switch of the original AP is the first port, and the port directly connected to the switch of the original AP is the second port, the first port is the same as the second port . That is, the MAC address of the directly connected port of the replacement AP is the same as the MAC address of the directly connected port of the original AP. The information of the newly launched AP is different from the information of other APs currently online. AP information includes model, serial number, and MAC address of directly connected ports.

Based on this, the AC can query the AP information table for the second working parameter information corresponding to the target model and the MAC address of the target directly connected port. If the second working parameter information exists in the AP information table, it indicates that the target AP is a replacement AP of the original AP, and the AC performs step 204. If the second working parameter information does not exist in the AP information table, the target AP is a newly launched AP, and the AC may not process or return a failure response message.

In the embodiment of the present application, the AC may further store default working parameter information in advance. The default working parameter information can be configured by the management staff. If the second working parameter information does not exist in the AP information table, the AC may send a discovery response message to the target AP. After receiving the discovery response message sent by the AC, the target AP can send a join request message to the AC. The AC sends a join response message to the target AP. After receiving the join response message sent by the AC, the target AP can send a configuration request message to the AC. After the AC receives the configuration request message sent by the target AP, it can send a configuration response message to the target AP. The configuration response message carries default working parameter information. In this way, after receiving the configuration response message sent by the AC, the target AP can provide wireless access services to the terminal according to the default working parameter information carried in the configuration response message, thereby achieving automatic configuration of the AP.

Optionally, if the first working parameter information exists in the AP information table, a third communication packet is sent to the target AP, and the third communication packet carries the first working parameter information, so that the target AP is associated with the AC , Providing a wireless access service according to the first working parameter information.

In implementation, if the first working parameter information exists in the AP information table, the AC may send a discovery response message to the target AP. After receiving the discovery response message sent by the AC, the target AP can send a join request message to the AC. After receiving the join request message sent by the AP, the AC can authenticate the target AP. If the authentication succeeds, the AC can send a join response packet to the target AP. After receiving the join response message sent by the AC, the target AP can send a configuration request message to the AC. After receiving the configuration request message sent by the target AP, the AC may send a configuration response message (ie, a third communication message) to the target AP. The configuration response message carries first working parameter information. In this way, after receiving the configuration response message sent by the AC, the target AP can provide the terminal with a wireless access service according to the first working parameter information carried in the configuration response message.

For example, the target model of the target AP is A; the target serial number is 123. The AC can query the working parameter information corresponding to the target model and target serial number in the AP information table. As shown in Table 1, the SSID in the queried working parameter information is X; Channel is 1; Max_Power is 20. Then, after receiving the configuration request message sent by the target AP, the AC sends a configuration response message to the target AP. The configuration response message carries the working parameter information queried above: SSID is X; Channel is 1; Max_Power is 20. The target AP can provide X based on the SSID; 1 for the Channel; and 20 for Max_Power to provide wireless access services to the terminal.

Optionally, if the first working parameter information exists in the AP information table, the AC may further determine whether the MAC address of the directly connected port to be updated in the AP information table is the same as the MAC address of the target directly connected port. The MAC address of the directly connected port to be updated corresponds to the target model and target serial number. If the MAC address of the directly connected port to be updated in the AP information table is different from the MAC address of the target directly connected port, modify the MAC address of the directly connected port to be updated to the MAC address of the target directly connected port.

In implementation, if the first working parameter information exists in the AP information table, the AC may further query the MAC address of the port to be updated in the AP information table, and then determine whether the MAC address of the port to be updated is directly connected to the target. The MAC addresses of the ports are the same. If the MAC address of the directly connected port to be updated is different from the MAC address of the target directly connected port, it means that the directly connected port of the target AP has changed. The AC can modify the MAC address of the directly connected port in the AP information table to MAC address of the target directly connected port. If the MAC address of the directly connected port to be updated is the same as the MAC address of the target directly connected port, it means that the directly connected port of the target AP has not changed, and the AC does not need to update the MAC address of the directly connected port.

For example, the target model of the target AP is A; the target serial number is 123; and the MAC address of the target directly connected port is 00-00-00-00-00-04. The AC can query the first working parameter information corresponding to the target model and target serial number in the AP information table, and then further query the MAC address of the directly connected port to be updated. As shown in Table 1, the inquired directly connected to be updated The MAC address of the port is 00-00-00-00-00-01, and 00-00-00-00-00-01 is different from 00-00-00-00-00-04, which means that the target AP's directly connected port When a change occurs, the AC can modify the MAC address of the directly connected port (ie, 00-00-00-00-00-01) to the MAC address of the directly connected port (ie, 00-00-00-00-00-04). ), As shown in Table 2.

Table II

Step 204: If the working parameter information corresponding to the target model and the MAC address of the target directly connected port exists in the AP information table, send a second communication packet to the target AP, and the second communication packet carries the queried working parameters. Information to enable the target AP to provide a wireless access service according to the queried working parameter information after it is associated with the AC.

Step 204 is: if the second working parameter information exists in the AP information table, send a second communication message to the target AP, and the second communication message carries the second working parameter information, so that the target AP is associated with the AC After that, a wireless access service is provided according to the second working parameter information.

In implementation, if the second working parameter information exists in the AP information table, it indicates that the target AP is a replacement AP of the original AP, and the AC can send a discovery response message to the target AP. After receiving the discovery response message sent by the AC, the target AP can send a join request message to the AC. After receiving the join request message sent by the AP, the AC directly sends a join response message to the target AP. After receiving the join response message sent by the AC, the target AP can send a configuration request message to the AC. After the AC receives the configuration request message sent by the target AP, it can send a configuration response message (that is, a second communication message) to the target AP. The configuration response message carries the queried second working parameter information. In this way, after receiving the configuration response message sent by the AC (that is, after the target AP is associated with the AC), the target AP can provide wireless access services to the terminal according to the second working parameter information carried in the configuration response message, thereby achieving the AP Automatic configuration without the need for administrators to configure the target AP, improving maintenance efficiency.

For example, the target model of the target AP is A; the MAC address of the target directly connected port is 00-00-00-00-00-01. The AC can query the second working parameter information corresponding to the target model and the MAC address of the directly connected port in the AP information table. As shown in Table 1, the SSID in the working parameter information is X; Channel is 1; Max_Power is 20 . Then, after receiving the configuration request message sent by the target AP, the AC sends a configuration response message to the target AP. The configuration response message carries the working parameter information queried above: SSID is X; Channel is 1; Max_Power is 20.

Optionally, if the second working parameter information exists in the AP information table, the AC may also modify the serial number to be updated in the AP information table to the target serial number, and the serial number to be updated is related to the target model and the MAC address of the target directly connected port. correspond.

In implementation, if the second working parameter information exists in the AP information table, it indicates that the target AP is a replacement AP of the original AP, and the AC may further modify the sequence number to be updated in the AP information table to the target sequence number. In this way, after the target AP is subsequently started, the AC can directly query the first working parameter information corresponding to the target model and target serial number in the AP information table.

For example, the target model of the target AP is A; the MAC address of the target directly connected port is 00-00-00-00-00-01; and the target serial number is 321. As shown in Table 3, the AC can find the to-be-updated serial number (ie, 123) corresponding to the target model and the MAC address of the directly connected port in the AP information table, and the to-be-updated serial number (ie, 123) in the AP information table. Modify it to the target serial number (ie 321).

Table three

An embodiment of the present application further provides an AP management method, which can be applied to a target AP, as shown in FIG. 3, and the specific steps are as follows:

Step 301: Send a first communication message to the AC.

The first communication packet may carry a target model, a target serial number, and a MAC address of a target directly connected port obtained by the target AP. The target directly connected port is a port on the switch that is directly connected to the target AP.

In implementation, after the target AP is started, the target AP can obtain the MAC address of a port on the switch directly connected to the target AP through LLDP. Then, the target AP may send a first communication packet to the AC. The first communication message carries a target model, a target serial number, and a MAC address of a target directly connected port obtained by the target AP.

Optionally, the first communication message may be a discovery request message or a join request message. The embodiment of the present application is described by using the first communication message as a discovery request message as an example. Correspondingly, after the target AP starts, the target AP can obtain the MAC address of the port on the switch directly connected to the target AP through LLDP. Then, the target AP can send a discovery request message to the AC in the WLAN. The discovery request message carries the target model, target serial number, and MAC address of the target directly connected port of the target AP. The situation in which the first communication message is a join request message is similar, and details are not described in the embodiment of the present application.

Among them, the target AP can carry the MAC address of the target directly connected port by adding a TLV field to the discovery request message.

Step 302: Receive a second communication message carrying working parameter information sent by the AC, and provide a wireless access service according to the working parameter information.

In implementation, after receiving the join response message sent by the AC, the target AP may send a configuration request message to the AC. Then, after receiving the configuration response message (that is, the second communication message) sent by the AC, the target AP can analyze the configuration response message to obtain the working parameter information carried in the configuration response message. In this way, the target AP can provide wireless access services to the terminal according to the working parameter information.

Optionally, the target AP can obtain the MAC address of the directly connected port through the LLDP protocol.

In implementation, after the target AP is connected to the switch, the switch can send LLDP packets to the target AP through the target directly connected port connected to the target AP. The LLDP packet carries the MAC address of the directly connected port. After receiving the LLDP packet, the target AP parses the LLDP packet to obtain the MAC address of the directly connected port carried in the LLDP packet.

Step 403: The AC queries the working parameter information corresponding to the target model and the target serial number in a pre-stored AP information table.

Step 403 is that the AC queries the working parameter information corresponding to the target model and target serial number in the AP information table stored in advance as the first working parameter information.

Step 404: If the working parameter information corresponding to the target model and target serial number exists in the AP information table, the AC determines whether the MAC address of the directly connected port corresponding to the target model and target serial number in the AP information table is the same as the target directly connected port. The MAC address is the same.

Step 404 is: if the first working parameter information exists in the AP information table, the AC determines whether the MAC address of the directly connected port to be updated in the AP information table is the same as the MAC address of the target directly connected port, and the MAC of the directly connected port to be updated The address corresponds to the target model and target serial number.

In step 405, if the MAC address of the directly connected port corresponding to the target model and the target serial number in the AP information table is different from the MAC address of the target directly connected port, the AC will directly connect the port corresponding to the target model and target serial number. Change the MAC address of the target to the MAC address of the directly connected port.

Step 405 is: if the MAC address of the directly connected port to be updated in the AP information table is different from the MAC address of the target directly connected port, the AC changes the MAC address of the directly connected port to be updated to the MAC address of the target directly connected port.

Step 406: The AC sends a configuration response message to the target AP1.

The configuration response message carries first working parameter information, so that the target AP1 provides a wireless access service according to the first working parameter information after being associated with the AC.

The specific processing procedures of steps 401 to 406 are similar to the specific processing procedures of steps 201 to 204 and steps 301 to 302, and details are not described in the embodiment of the present application.

FIG. 5 is an example of an AP management method according to an embodiment of the present application. This example describes a processing flow of association between the target AP2 and the AC after the target AP2 replaces the target AP1. As shown in FIG. 5, the specific steps are as follows :

Step 501: The target AP2 obtains the MAC address of the directly connected port through LLDP.

Step 502: The target AP2 sends a discovery request message to the AC.

The discovery request message carries the target model, target serial number, and MAC address of the target directly connected port obtained by the target AP2.

Step 503: The AC queries the working parameter information corresponding to the target model and the target serial number in a pre-stored AP information table.

Step 503 is that the AC queries the working parameter information corresponding to the target model and the target serial number in the AP information table stored in advance as the first working parameter information.

Step 504: If the working parameter information corresponding to the target model and the target serial number does not exist in the AP information table, the AC queries the working parameter information corresponding to the target model and the MAC address of the target directly connected port in the AP information table.

Step 504 is: if the first working parameter information does not exist in the AP information table, the AC queries the second working parameter information corresponding to the target model and the MAC address of the target directly connected port in the AP information table.

Step 505: If the working parameter information corresponding to the target model and the MAC address of the target directly connected port exists in the AP information table, the AC modifies the serial number corresponding to the target model and the MAC address of the target directly connected port in the AP information table to The target serial number.

Step 505 is: if the second working parameter information exists in the AP information table, the AC changes the to-be-updated serial number in the AP information table to the target serial number, and the to-be-updated serial number corresponds to the target model and the MAC address of the target directly connected port .

Step 506: If the working parameter information corresponding to the target model and the MAC address of the target directly connected port exists in the AP information table, the AC sends a configuration response message to the target AP2.

Step 506 is: if the second working parameter information exists in the AP information table, sending a configuration response message to the target AP2.

The configuration response message carries the second working parameter information, so that the target AP2 provides a wireless access service according to the second working parameter information after being associated with the AC.

The specific processing procedures of steps 501 to 506 are similar to the specific processing procedures of steps 201 to 204 and steps 301 to 302, which are not described in the embodiment of the present application.
