According to the invention, before formal packet sending test, each port of the tested communication equipment sends a data packet carrying port information of the tested communication equipment, the physical connection relation of the ports is automatically obtained by analyzing the port information contained in the received data packet, and then the vlan or vrf configuration is automatically carried out, so that the test scheme can flexibly adapt to various connection conditions and even any connection mode.

and the counting and judging module is used for counting and comparing the number of the sent messages and the number of the received messages of different ports in the chain data flow link so as to judge whether the ports are normal or not.
Fig. 2 shows a method for implementing port data forwarding test of a communication device based on the tested communication device, which includes the following steps:
s201, before a data forwarding test, each port sends a specific data packet containing self port information to the outside;
in this step, before the data forwarding test, each port of the communication device under test sends a small number of data packets to the outside, where the data packets include port information;
s202, after receiving specific data packets sent by other ports, each port carries out port analysis to obtain physical interconnection information of the port and the other ports;
in this step, after receiving the data packets sent by other ports, a certain port analyzes the port information in the data packets, so as to obtain the physical interconnection information between the ports according to the port number of the certain port and the analyzed port number;
such as: and if the port 1 receives the data packet of the port 2 and the port 2 receives the data packet of the port 1, the port 1 and the port 2 are physically interconnected (connected through a network cable or a test fixture).
S203, carrying out virtual network configuration on the ports according to the physical interconnection information of all the ports of the same type, and configuring all the ports into a chained data flow link formed by physical interconnection and a virtual network;
in the step, the system randomly selects two ports which are not physically interconnected according to the physical interconnection information of all the ports of the same type as a test packet sending port and a test packet receiving port respectively, and divides the ports into different virtual networks (vlans or vrf); dividing the rest ports into different virtual networks according to the rule that two ports which are physically interconnected are divided into different virtual networks;
after being partitioned by the virtual network, all ports are configured into data flow links formed by the physical interconnect and the partitioned virtual network.
S204, a CPU of the tested communication equipment constructs a test message according to the port configuration condition and sends the test message to the chained data flow link;
in this step, the CPU of the communication device under test constructs a test packet using the MAC address of the test packet sending port as a source address and the MAC address of the test packet receiving port as a destination address, and sends the test packet through the test packet sending port.
S205, the number of the sent messages and the number of the received messages of the two ports in the chain type data flow link are counted and compared, and therefore whether the ports are normal or not is judged.
In this step, whether the ports are normal is judged by counting whether the receiving and sending numbers of the data packets of the two ports in the chained data stream link are consistent, if so, the test is passed, and if not, the test is failed, and the two inconsistent ports are reported so as to facilitate further manual analysis and processing.
Such as: for ports 1 and 2 which are physically interconnected, in the data forwarding process of a data stream link, data packets received by port 1 are forwarded to port 2, data packets received by port 2 are forwarded to port 1, and then whether port 1 and port 2 are normal is judged by judging whether the number of data packets sent by port 1 is consistent with the number of data packets received by port 2, and judging whether the number of data packets received by port 1 is consistent with the number of data packets sent by port 2.
Example 1:

4) The CPU of the tested communication equipment constructs a test message, and sends the test message to a data flow link:
the CPU of the tested communication equipment constructs a test message which takes the MAC address of 1 port as a source address and the MAC address of 10 ports as a destination address, generates a data stream after an internal storm of a switching chip, and sends the data stream from 1 port, wherein the data stream returns to 10 ports after traversing all the ports according to the sequence of 1-2-3-5-4-8-6-9-7-10;
similarly, a test message with the 10-port MAC address as a source address and the 1-port MAC address as a destination address is constructed, and a data stream is generated after an internal storm of the switching chip, and sent from the 10 ports, and the data stream returns to the 1 port after traversing all the ports according to the sequence of "10-7 ═ 9-6 ═ 8-4 ═ 5-3 ═ 2-1".
5) After the test is stopped after a period of time, the number of the sending packets of the port 1 and the number of the receiving packets of the port 10 are compared, and the number of the sending packets of the port 10 and the number of the receiving packets of the port 1 are compared, so that whether all the ports work normally can be known.
It should be noted that, for the tested communication devices with multiple types or different speed ports, the ports of the tested communication devices of the same type or the same speed are subjected to port physical connection identification and vlan partition according to the above operations, and then the test results of the ports of each type or speed can be obtained through respective tests.
