Fig. 1 is a flowchart of a method for testing a switch according to an embodiment of the present invention.
The switch to be tested mainly comprises a CPU, a switching chip and a network port. The switching chip adopted in the switch to be tested in the embodiment of the invention is a domestic switching chip (currently, only CTC8096 produced by department of the Ministry). On the basis, the switch to be tested can be a switch made in China, namely, main components such as a CPU (Central processing Unit) and a switching chip are designed and manufactured by domestic manufacturers. The CPU of the switch to be tested can adopt Loongson 2K1000, the CPU is connected with a switching chip (Shengke CTC8096) through a PCIe bus (PCIe multiplied by 2), and the switching chip is connected with a network port through a serializer/deserializer (serdes).
The embodiment of the invention can be connected with the CPU and the switching chip of the switch to be tested through one testing host, drive the CPU and the switching chip of the switch to be tested through the driving program, and acquire information through the CPUC of the switch to be tested to carry out detection.
Before testing, hardware information of the switch to be tested can be obtained through a driver; judging whether the exchange chip is CTC8096 according to the hardware information; if yes, go to the following step S101; if not, the test is ended. The specific procedure can be as follows:
int get_chip_hwinfo(ctc_chip_device_info_t*device_info)
{
ret＝ctc_chip_get_property(0,CTC_CHIP_PROP_DEVICE_INFO,(void*)device_info)；
return ret；
}
as shown in fig. 1, a method for testing a switch according to an embodiment of the present invention includes:
s101: and sequentially connecting each network port in the test group of the switch to be tested to obtain a test link corresponding to the test group and enable each network port.
The number of the network ports of the switch to be tested is usually an even number, and in order to facilitate the test of the data transceiving function of the network ports, the number of the network ports in each test group is ensured to be the even number when the test groups are divided. By connecting the network ports in a test group into a test link, data transceiving tests can be conveniently and respectively carried out from the two ends of the test link, whether each network port has the functions of receiving and forwarding data packets or not is confirmed, and packet loss is avoided. For convenience of testing, all network ports on the switch to be tested can be taken as a test group.
In a specific implementation, step S101 may include: connecting the network ports in the test group by taking two network ports as a group to obtain a test pair; enabling each network port; and adding the adjacent network ports of the two adjacent test pairs into the same virtual local area network according to the connection sequence of the test pairs to obtain a test link corresponding to the test group.
The network ports in the test group are connected by taking two network ports as a group to obtain a test pair, specifically, an optical cable connector (such as a 10G AOC cable) can be adopted to connect the upper and lower two network ports respectively according to the serial number of the network ports on the switch to be tested, namely, the network port 1 and the network port 2 on the switch to be tested are connected by the 10G AOC cable, and the network port 3 and the network port 4 on the switch to be tested are connected by the 10G AOC cable … … and so on.
Since the network ports of the domestic switch default to the power-down state, all the network ports need to be enabled to be powered on. Taking an example that the switch to be tested has 54 network ports in total, the specific procedure is as follows:
and further creating Virtual Local Area Networks (VLANs) which are in one-to-one correspondence with the test pairs, and adding two network ports in the test pairs into the corresponding virtual local area networks, aiming at enabling all the network ports to logically form a link. If the network port 1 and the network port 2 on the switch to be tested are connected by using 10G AOC cable, and the network port 3 and the network port 4 on the switch to be tested are connected by using 10G AOC cable … …, in this step, the network port 2 and the network port 3 are added into the first virtual local area network, the network port 4 and the network port 5 are added into the second virtual local area network … …, and so on. If the virtual local area network is not successfully created in the step, the switching chip is not normal in function, and maintenance analysis is needed. Before executing the next step (step S102), the method for testing a switch provided in the embodiment of the present invention may further include:
judging whether each virtual local area network is successfully established; if yes, go to step S102; if not, outputting the abnormal information of the exchange chip and ending the test.
Taking 54 network ports of the switch to be tested in total and taking all the network ports of the switch to be tested as a test group as an example, 27 virtual local area networks can be created, if the ID of the first virtual local area network is 10, the network port 2 and the network port 3 are added into the VLAN 10, the network port 4 and the network port 5 are added into the VLAN 11, … … is performed, and so on. Specific procedures are referenced below:
after the virtual local area network is created, to avoid performing an invalid test when the switch to be tested is in a fault state, before step S102, the method for testing the switch provided in the embodiment of the present invention may further include:
judging whether each network port is in a working state and operates at a chip set frequency based on the switching chip; if yes, entering a step of sending a first preset number of first data packets to a network port of the head end; and if not, outputting a network port connection error prompt.
Whether the virtual local area network is successfully set or not is judged through data interaction with the exchange chip, whether all network ports are in a working state (up) or not and whether all network ports are in a chip set frequency (such as 10G, 40G and 100G) or not is judged, and when any one of the network ports is not met, information of abnormal connection of the network ports is output, and a user is prompted to check the connection condition of each network port through an optical cable connector. And the user checks the optical cable connector with abnormal connection and re-executes the step of performing data interaction check connection with the exchange chip after the optical cable connector is connected and connected. If the user checks that all the optical cable connectors are normally connected, the fact that the switch to be tested has a fault is indicated, maintenance and analysis are needed, and the next testing is not needed.
S102: and based on the switching chip of the switch to be tested, sending a test data packet to the test link, and detecting the data transceiving performance of each network port in the test link.
In order to facilitate the comparison between the sending and receiving packets and the statistics of the number of the lost packets, the status register may be cleared before step S102. The type of the test data packet may be a unicast packet, a multicast packet, a broadcast packet, or the like.
And sending a test data packet to the test link through the CPU of the switch to be tested, and detecting the data transceiving performance of each network port in the test link. Preferably, the test data packet is sent from the head end or the tail end of the test link, and the packet sending and receiving comparison and the packet loss statistics and other analysis are performed by receiving the message from the other end, so as to obtain the data transceiving performance of each network port in the test link.
S103: and determining the test result of the switch to be tested according to the data transceiving performance of each network port.
If the number of the received messages is not equal to that of the forwarded messages or packet loss occurs, it indicates that the switch to be tested fails the test and needs to be maintained and analyzed; otherwise, the test is passed.
The switch testing method provided by the embodiment of the invention comprises the steps of firstly, sequentially connecting each network port in a testing group of a switch to be tested to obtain a testing link corresponding to the testing group, and enabling each network port; then based on the switching chip of the switch to be tested, sending a test data packet to the test link, and detecting the data transceiving performance of each network port in the test link; and determining the test result of the switch to be tested according to the data transceiving performance of each network port. The test data packet is sent to the network port of the switch to be tested through the switching chip of the switch to be tested, the data transceiving performance of each network port is tested, the performance of the domestic switch is tested, the complete production line of the domestic switch is facilitated, and the production scale of the domestic switch is enlarged.

judging whether the quantity of the first messages is a first preset quantity and the quantity of the second messages is a second preset quantity; if so, determining that the switch to be tested passes the test; if not, determining that the switch to be tested does not pass the test.
In the specific implementation, taking 54 network ports of the switch to be tested in total and taking all the network ports of the switch to be tested as a test group as an example, a first preset number (for example, 2000000) of first test data packets may be sent to the network port 1 through the CPU of the switch to be tested, a first message of the network port 54 is obtained through the switch chip, and it is detected whether the number of the first message is 2000000, if so, the step passes the test, otherwise, it is determined that the switch to be tested does not pass the test.
And then, sending a second preset number (for example, 2000000) of second test data packets to the network port 54 through the CPU of the switch to be tested, acquiring a second message of the network port 1 through the switch chip, and detecting whether the number of the second message is 2000000, if so, the step passes the test, otherwise, determining that the switch to be tested does not pass the test.
The sequence of the two steps can also be reversed, and if both pass the test, the switch to be tested passes the test.
On the basis that the test data packet adopts the unicast packet, the test data packet specifically comprises a third test data packet and a fourth test data packet. In the method for testing a switch provided in the embodiment of the present invention, step S102: based on the switching chip of the switch to be tested, sending a test data packet to the test link, and detecting the data transceiving performance of each network port in the test link, specifically comprising:
