Next, examples of the present application will be described in detail.
An embodiment of the present application provides a configuration information synchronization method, which is applied to any Fit AP in a WLAN, and as shown in fig. 2, the method may include the following steps:
and S21, receiving a synchronization command sent by the main AC connected with the Fit AP in the WLAN.
In this step, the synchronization command is sent by the master AC when receiving the synchronization command entered by the administrator on the AP template of the Fit AP.
And S22, if the synchronization instruction is the synchronization instruction received by the Fit AP for the first time and the configuration information issued by the main AC is locally recorded, synchronizing the locally recorded configuration information with the standby AC connected with the Fit AP.
S23, if the synchronous instruction is not the synchronous instruction received by the Fit AP for the first time, comparing whether the configuration information recorded when the synchronous instruction is received last time is consistent with the configuration information recorded when the synchronous instruction is received at the current time; if the comparison result is negative, executing step S24; if the comparison result is yes, step S25 is executed.
And S24, synchronizing the newly added configuration information to the standby AC.
And S25, ending the flow.
It should be noted that, in the embodiment of the present application, an administrator may input a synchronization instruction on the AP template of the Fit AP on the main AC side according to an actual configuration requirement.
For example, the administrator may input a synchronization command on the AP template of the Fit AP on the main AC side at a set period.
For another example, the administrator may input a synchronization command on the AP template of the Fit AP on the main AC side, when it is necessary to verify whether the configuration information on the main AC and the standby AC are consistent, or the like.
For the Fit AP, every time configuration information sent by the main AC is received, the relevant configuration is locally performed, and the relevant configuration is recorded. And when receiving the synchronization instruction sent by the main AC, the configuration information recorded at the current time is marked with the number of times of receiving the synchronization instruction, so as to compare the configuration information with the configuration information recorded when receiving the synchronization instruction at the last time.
It should be further noted that, after the step S21 is executed, in the case that the synchronization instruction is the synchronization instruction that is first received by the Fit AP and the configuration information issued by the main AC is not locally recorded, the flow is ended, that is, the relevant synchronization operation is not executed.
Specifically, in step S22, when synchronizing the configuration information of the local record with the standby AC connected to the Fit AP, the Fit AP may specifically send a CAPWAP Echo request message carrying the configuration information of the local record to the standby AC.
Here, a value of a Message Type (Message Type) field in the CAPWAP Echo request Message may be 30, so as to indicate that when the AC receives the CAPWAP Echo request Message with the Message Type field value of 30, the AC extracts the relevant configuration information carried in the CAPWAP Echo request Message, and performs a local configuration operation.
In step S24, when synchronizing the new configuration information to the standby AC, the Fit AP may specifically send a CAPWAP Echo request packet carrying the new configuration information to the standby AC.
Further, in the embodiment of the present application, the Fit AP may further perform the following operations:
receiving a CAPWAP Echo response message which is sent by the standby AC and aims at the received CAPWAP Echo request message, wherein the CAPWAP Echo response message carries a configuration result of the standby AC aiming at the received configuration information;
and sending the CAPWAP Echo response message to the main AC so that the main AC outputs the configuration result to the administrator.
In the above operation flow, the value of the Message Type field in the CAPWAP Echo response Message may be 31, so as to indicate that the host AC extracts the relevant configuration result carried in the CAPWAP Echo response Message when receiving the CAPWAP Echo response Message with the value of the Message Type field being 31. Here, the configuration result carried in the CAPWAP Echo response message may be a successful configuration or a failed configuration.
By executing the operation flow through the Fit AP, an administrator can timely know the configuration synchronization condition of the standby AC, can timely analyze failure reasons under the condition of configuration failure, and can timely perform network maintenance.
It can be seen from the above technical solutions that, in the embodiment of the present application, in the WLAN network, any Fit AP synchronizes the relevant configuration information to the standby AC based on the synchronization instruction input by the administrator and sent by the main AC, so as to achieve consistency of the relevant configuration information on the main AC and the standby AC. The configuration information synchronization mode can not generate configuration errors, and labor cost is greatly saved.

and a second synchronization module 34, configured to synchronize the newly added configuration information to the standby AC if the comparison result of the comparison module is negative.
Preferably, the apparatus further comprises:
and an ending module (not shown in fig. 3) configured to end the process when the comparison result of the comparison module is yes.
Preferably, the first synchronization module 32 is specifically configured to:

a sending module (not shown in fig. 3) configured to send the CAPWAP Echo response packet to the main AC, so that the main AC outputs the configuration result to the administrator.
It can be seen from the above technical solutions that, in the embodiment of the present application, in the WLAN network, any Fit AP synchronizes the relevant configuration information to the standby AC based on the synchronization instruction input by the administrator and sent by the main AC, so as to achieve consistency of the relevant configuration information on the main AC and the standby AC. The configuration information synchronization mode can not generate configuration errors, and labor cost is greatly saved.
