Controller, referred to as AC）, AC is to AP progress safety certifications, and from AC acquisition software images, AP obtains initial and dynamic AP from AC
State configuration etc..CAPWAP protocol transport layers transmit two kinds of load information：Data-message and control message.The use of CAPWAP
In carrying data-message data message and the control message for carrying control message be based on different User Datagram Protocol
View（User Datagram Protocol, referred to as UDP）What port was transmitted.
The use of CAPWAP agreements starts from the discovery phase of whole flow process.When AP sends a discovery request message,
Any AC for receiving this request will respond a discovery response message.After discovery response message is received, AP selections
One AC establishes a secured session based on DTLS.After session key agreement success, both sides can be used with a
Session key communicate.
Once AP and AC complete DTLS session establishments, configuration will be exchanged between the two, for being reached on version information
Into consistent.In this exchange process, AP may receive regulation setting, then can open these settings.When AP and AC it

AP heartbeat packets, then carry out AP under port power-off restarting, while the time that record is restarted, and adds 1 to restarting number.By to this
The statistics recorded a bit and analysis, realize effective management to AP.
5）Under each port setting unit review time, ap reboot time interval, in the unit interval packet receiving alarm number,
The alarm of ap reboot number and exception policy in unit interval.Can mainly have but be not limited to following several strategies：
1）Since port, AP heartbeat detections enable, each unit review time can be counted and divided to the data of record
Analysis；If not receiving AP heartbeat packets in ap reboot time interval, AP is restarted；
2）When the packet receiving number in the unit interval is more than the alarm number set, packet receiving number warning information is reported, can
The warning information to be reported to the webmaster on upper strata, to realize processing or control to AP.
3）When in the unit interval AP restart number be more than set alarm threshold be report and alarm information.
Preferably, after alarm is received, webmaster can carry out AP following processing, such as：Alert, alert and restart AP with
And alert and close AP.
By the above-mentioned means, after the AP heartbeat detections under completing port configure, when AP occurs abnormal, interchanger can
To be automatically performed the management to AP.When exception, which occurs, in AP to work, interchanger can carry out power-off restarting to AP, so as to exempt from
Manually-operated complexity is gone, improves the efficiency of management AP.
The present embodiment additionally provides a kind of AP heartbeat packets and realizes flow, as shown in figure 5, comprising the following steps：
Step S502：Port open AP heartbeat packets enable, only enabled port, can just carry out AP heartbeat packet inspections
