The power required by the AP increases due to the increased amount of wireless traffic being transmitted and is constantly hopping during this process. The PoE switch is used as an output end for supplying power to the AP, and power supply and data transmission stability of the AP need to be ensured. In an actual use scene, each AP can have an indefinite number of wireless clients connected to the network, and the work stability of the PoE switch in the scene is tested.
The ports of a PoE switch can reach 24 or 48 ports, and the current test scheme is that after the PoE switch is fully loaded with APs, a wireless client is connected with each AP to surf the Internet.

If the stability of the PoE switch is only verified in the idle load or light load state of the AP, the simulation of a real belt machine cannot be achieved. If a small number of wireless clients are connected with the AP signal to surf the internet, the AP cannot work and operate to reach the maximum power consumption, so that the switch cannot reach the maximum power output in the scene,

FIG. 2 is a flow chart of the testing method of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1 and fig. 2, the present invention is directed to a PoE switch in which the MAC address Learning mode is an IVL (Independent VLAN Learning) mode, and solves a test scheme that the type of switch can operate an AP and achieve maximum power consumption even if a wireless client is absent after the AP is loaded.
The invention adopts the mode of VLAN isolation and AP bridging of the switch, so that the port of the switch is self-looped but does not generate broadcast storm, and the maximum wireless flow transmission and power output are achieved. Taking a 24-port PoE switch as an example, the testing method and the testing system of the present invention are described as follows:
1. determining power of AP
An AP is accessed to a shielded room switch without other wireless signals, for example, a tenda W75AP is taken as a dual-frequency AP, and since bridging is used in the following steps of the AP and 2.4G and 5G signals between the APs cannot be bridged simultaneously, two wireless clients are only connected to 5G signal Ixchariot for 5 minutes. And selecting the port number by adopting a python automation program while running, executing the switch serial port command show power every 5 seconds, and acquiring the output power on the switch port to obtain the peak power consumption of the AP in the running process. The maximum peak power of the W75AP in 5 minutes is 15.8W, and the average power is about 10W. Therefore, the maximum peak power that can be reached is determined to be the power of the AP.
2. VLAN configuration on the tested exchanger
Configuring VLAN (virtual local area network) to a switch port pair, such as adding port1 and port2 into VLAN 2; VLAN3 is added into port3 and port4; 8230, until all ports are configured, 12 VLAN pairs are formed.
3. Configuring and connecting APs
1. And determining the access number of the AP. If the maximum output power of the PoE is 370W, the number of the access W75 APs is the total power/peak power. The peak power is measured to be 15.8W in the first step, and 370/15.8=23.4 accessible APs are actually accessed to 23 APs.
2. And configuring the IP address and the SSID signal name of the AP. The IP addresses are continuous addresses 192.168.1.1, 192.168.1.2 \8230; 192.168.1.23; SSID names are SSID1, SSID2, SSID3 \8230, SSID23.
3. AP5G wireless signal bridging is configured, starting with SSID signal SSID2, SSID2 is bridged to SSID3, SSID4 is bridged to SSID5, and SSID6 is bridged to SSID7 \8230, until SSID23 is bridged.
4. In order to avoid the mutual interference caused by the sharing of the channel by all the APs, the Ixchariot running stream cannot reach the maximum traffic transmission, so that the two bridged APs are configured in the same channel but are separated from other bridged AP pairs.
5. And accessing the AP to the corresponding switch port according to the SSID serial number. A PoE onboard AP stability test topology is shown in fig. 1.
4. Stability test
1. The whole test is implemented in a shielded room so as to avoid signal interference and cause incapability of Ixchoriot running;
2. the wireless network card C on the PC A is connected with the AP SSID signal SSID1, and the wired network card D on the PC B is connected with the 24 ports of the switch;
3. starting IxChariot on one PC, setting IP addresses of the A end and the B end, and running;
4. starting an on-hook test, wherein flow transmission is uninterrupted in the test process, and meanwhile, a network card of one PC pings the IP addresses of all APs and records whether the APs are off-line in the on-hook process;
5. and acquiring the maximum output power of the PoE and the output of each port once by adopting an automatic program for 10 seconds in the on-hook process, and if the maximum output limit of the switch is exceeded due to the fact that the AP absorbs high power at the same time at a certain moment, determining whether the port with low priority is disconnected or not due to the power supply priority of the switch.
In the step 2, if the other APs form the bridging AP pair except the first AP and the last AP drops, the PC B may directly wirelessly connect to the wireless network of the last AP and run between the PC AB. The tested exchanger can reach full load, and the maximum wireless flow transmission and power output can be reached.
Certainly, when the number of the spare ports of the tested switch is multiple, the last port can be connected to verify the reliability of all the ports, and in the process of hanging up, if the AP absorbs high power at a certain moment at the same time and exceeds the maximum output limit of the switch, the stability performance of the tested switch is verified by verifying the processing of the tested switch on the priority of all the ports according to whether the disconnection priority of the ports of the tested switch is consistent with the power supply priority.
Any port except the first connected AP can be connected, so that the reliability of the PoE switch when part of the ports are lightly loaded in power and part of the ports are heavily loaded in power is verified.
The principle of the scheme of the invention is as follows:
and the same MAC address is learned into different VLANs by utilizing an IVL MAC address learning mode of the switch. The wireless network card C and the wired network card D are communicated with each other, firstly, the C sends an ARP broadcast request message, the message enters a port1 of the switch, the MAC of the C is learned to a port1+ VLAN2, meanwhile, the message is broadcast to a port2, an AP signal ssid2 of the port2 is bridged with ssid3, the message directly reaches a port3 of the switch, the MAC address is learned to a port3+ VLAN3, and the MAC address of the C is learned to a port23+ VLAN23. The wireless network card D responds to the ARP unicast packet of C at the port24, according to the destination address and the VLAN corresponding to the input port, the MAC address table learned by broadcasting sent by C before is searched for forwarding, the message can directly reach the port1 and is sent to C, and meanwhile, the MAC address of D learns all VLANs and corresponding ports. The wireless network card C and the wired network card D can unicast traffic to each other. The wireless network card receives and transmits large flow, and simultaneously, the AP power is increased, so that the stability of data transmission and power increase output when the PoE switch carries the AP can be verified.
The invention can realize the traffic load of all the APs on the exchange by only one or two wireless clients, thereby saving the access of the wireless clients; the wireless client can be connected with the SSIDs of any two APs on the switch to run, broadcast storms cannot be generated, and meanwhile, the reliability of the PoE switch when part of ports are lightly loaded in power and part of ports are heavily loaded is verified.
