Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example one
As shown in fig. 1, the port testing method of the switch according to the preferred embodiment of the present invention includes the following steps:
step S11, the network tester sends a data packet to a first preset port of the switch through the first port;
step S12, the network tester receives the data packet sent back by the switch through the second preset port through the second port;
step S13, when the scheduled time for sending the package is reached, the network tester controls the first port to stop sending the package;
and step S14, the switch analyzes the test data through the test program and feeds back the test result through the port indicator lamp on the switch panel.
As shown in fig. 3, the double-line is a physical network connection outside the switch, and connects two ports of the switch or connects the switch and a port of the network tester, respectively, and two ports connected by one physical network line are connected to each other. The single dotted line is a port connection configured inside the switch, which means that two ports connected to the single dotted line are communicated with each other inside the switch, and this is a configuration that all commercial switches support, and the essential principle is to divide a plurality of ports (here, two ports) of the switch into a group, and the ports in the group can forward messages to each other, and are not communicated with other ports outside the group, and one port can only be in one group. The configuration of the switch in the present invention is that the default 48 ports (of course, other number of ports, for example, 8 ports) are in the same group.
As shown in fig. 3, a first port of the network tester is port a in fig. 3, a second port of the network tester is port b in fig. 3, a first default port of the switch is port 1 in fig. 3, and a second default port of the switch is port 2 in fig. 3. Two ports (a, b) of the network tester are respectively connected with two ports (1, 2) of the switch, one port sends a data packet, and the other port receives the data packet.
Specifically, the network tester sends a data packet to port 1 of the switch through port a; the network tester receives the data packet sent back by the switch through the port 2 through the port b; when the scheduled packet sending test duration is reached, the network tester control port a stops sending packets; the switch analyzes the test data through the test program and feeds back the test result through the port indicator lamp on the switch panel.
Further, the rate of sending the data packet to the first preset port (port 1) of the switch through the first port (port a) by the network tester is the maximum rate of the port of the switch, and the maximum rate is 1000 Mbps. The presence or absence of a problem in the case of the maximum packet transmission rate indicates that there is no problem with the transmission because some problems are not detected at the normal rate. The switch port rate is 1000M and packets are sent at 1000Mbps rate.
As shown in fig. 3, after a data packet sent from port a of the network tester is forwarded through 48 ports of the switch, a process of receiving the data packet sent from port a by port b is as follows:
the port a of the network tester sends N data packets to the port 1 of the switch, and the port 1 of the switch forwards the N data packets to the port 48;
switch port 48 forwards N packets to port 47- > switch port 47 forwards N packets to port 46- >;
switch port 46 forwards N packets to port 45- - > switch port 45 forwards N packets to port 44- - >;
switch port 44 forwards N packets to port 43- > switch port 43 forwards N packets to port 42- >;
the switch port 42 forwards N data packets to the port 41- - > the switch port 41 forwards N data packets to the port 40- - >;
the switch port 40 forwards N data packets to the port 39- - > the switch port 39 forwards N data packets to the port 38- - >;
switch port 38 forwards N packets to port 37 > switch port 37 forwards N packets to port 36 >;
the switch port 36 forwards N data packets to the port 35- - > the switch port 35 forwards N data packets to the port 34- - >;

switch port 30 forwards N packets to port 29 > switch port 29 forwards N packets to port 28 >;
switch port 28 forwards N packets to port 27 > switch port 27 forwards N packets to port 26- -;
switch port 26 forwards N packets to port 25- - > switch port 25 forwards N packets to port 24- -;
switch port 24 forwards N packets to port 23 > switch port 23 forwards N packets to port 22- -;
the switch port 22 forwards N data packets to the port 21- - > the switch port 21 forwards N data packets to the port 20- - >;
the switch port 20 forwards N data packets to the port 19- - > the switch port 19 forwards N data packets to the port 18- - >;
switch port 18 forwards N packets to port 17 > switch port 17 forwards N packets to port 16 >;
the switch port 16 forwards N data packets to the port 15- - > the switch port 15 forwards N data packets to the port 14- - >;
switch port 14 forwards N packets to port 13- - > switch port 13 forwards N packets to port 12- - >;

the switch port 10 forwards N data packets to the port 9- - > the switch port 9 forwards N data packets to the port 8- - >;
the switch port 8 forwards N data packets to the port 7- - > the switch port 7 forwards N data packets to the port 6- - >;
the switch port 6 forwards N data packets to the port 5- - > the switch port 5 forwards N data packets to the port 4- - >;
the switch port 4 forwards N data packets to the port 3- - > the switch port 3 forwards N data packets to the port 2- - >;
switch port 2 forwards N packets to network tester port b.
When the scheduled packet sending test duration is reached (for example, 24 hours), controlling the port a and the port b of the network tester to stop sending packets; at this time, all ports of the switch do not have data packets to be forwarded any more, a test program is run on the switch, and the quantity of the data packets sent and received by 48 ports respectively is collected; according to the sequence of the data packets forwarded in the 48 ports, the quantity of the data packets forwarded by the two connected ports is compared in sequence, if the quantity of the data packets forwarded by which port is less than the quantity of the data packets forwarded by the previous port, the performance of the port does not reach the standard, the test program controls the indicator lamp of the port to flash (each port has its own indicator lamp for displaying whether a network cable is plugged, and the test program is used for displaying the test result), so as to draw the attention of a tester.
For example, "switch port 3 forwards N packets to port 2," if the actual forwarding count for port 3 is 168750000000 and the actual forwarding count for port 2 is 168749999990, then port 2 has lost packets and port 2 performance does not meet the standard.
That is, the switch runs a test program, and collects the number of data packets sent and received by all ports on the switch; sequentially comparing the quantity of the data packets forwarded by the two connected ports according to the forwarding sequence of the data packets in all the ports; if the quantity of the data packets forwarded by the existing port is less than that of the data packets forwarded by the previous port, the performance of the current port does not reach the standard, and the indicator light of the current port is controlled to flicker through the test program.
Example two
As shown in fig. 2, the port testing method of the switch according to the preferred embodiment of the present invention includes the following steps:
step S21, the network tester sends a data packet to a second preset port of the switch through the second port;
step S22, the network tester receives the data packet sent back by the switch through the first preset port through the first port;
step S23, when the scheduled time for sending the package is reached, the network tester controls the second port to stop sending the package;
and step S24, the switch analyzes the test data through the test program and feeds back the test result through the port indicator lamp on the switch panel.
As shown in fig. 3, the double-line is a physical network connection outside the switch, and connects two ports of the switch or connects the switch and a port of the network tester, respectively, and two ports connected by one physical network line are connected to each other. The single dotted line is a port connection configured inside the switch, which means that two ports connected to the single dotted line are communicated with each other inside the switch, and this is a configuration that all commercial switches support, and the essential principle is to divide a plurality of ports (here, two ports) of the switch into a group, and the ports in the group can forward messages to each other, and are not communicated with other ports outside the group, and one port can only be in one group. The equipment of the switch is configured from factory in the invention, and the default 48 ports are all in the same group.
As shown in fig. 3, a first port of the network tester is port a in fig. 3, a second port of the network tester is port b in fig. 3, a first default port of the switch is port 1 in fig. 3, and a second default port of the switch is port 2 in fig. 3. Two ports (a, b) of the network tester are respectively connected with two ports (1, 2) of the switch, one port sends a data packet, and the other port receives the data packet.
Specifically, the network tester sends a data packet to port 2 of the switch through port b; the network tester receives the data packet sent back by the switch through the port 1 through the port a; when the scheduled packet sending test duration is reached, the network tester control port b stops sending packets; the switch analyzes the test data through the test program and feeds back the test result through the port indicator lamp on the switch panel. That is, since forwarding and communication are required to be bidirectional, the network tester may send a packet to port 1 of the switch through port a; the network tester receives the data packet sent back by the switch through the port 2 through the port b; or the network tester sends a data packet to the port 2 of the switch through the port b; the network tester receives the data packet sent back by the switch through the port 1 through the port a.
Further, the rate of sending the data packet to the second preset port (port 2) of the switch through the second port (port b) by the network tester is the maximum rate of the port of the switch, and the maximum rate is 1000 Mbps. The presence or absence of a problem in the case of the maximum packet transmission rate indicates that there is no problem with the transmission because some problems are not detected at the normal rate. The switch port rate is 1000M and packets are sent at 1000Mbps rate.
As shown in fig. 3, after a data packet sent by port b of the network tester is forwarded through 48 ports of the switch, the process of port a receiving the data packet sent by port b is as follows:
the port b of the network tester sends N data packets to the port 2 of the switch, and the port 2 of the switch forwards the N data packets to the port 3;
the switch port 3 forwards N data packets to the port 4- - > the switch port 4 forwards N data packets to the port 5- - >;
the switch port 5 forwards N data packets to the port 6- - > the switch port 6 forwards N data packets to the port 7- - >;

switch port 47 forwards N packets to port 48- > switch port 48 forwards N packets to port 1- >;
switch port 1 forwards N packets to network tester port a.
When the scheduled packet sending test duration is reached (for example, 24 hours), controlling the port b and the port a of the network tester to stop sending packets; at this time, all ports of the switch do not have data packets to be forwarded any more, a test program is run on the switch, and the quantity of the data packets sent and received by 48 ports respectively is collected; according to the sequence of the data packets forwarded in the 48 ports, the quantity of the data packets forwarded by the two connected ports is compared in sequence, if the quantity of the data packets forwarded by which port is less than the quantity of the data packets forwarded by the previous port, the performance of the port does not reach the standard, the test program controls the indicator lamp of the port to flash (each port has its own indicator lamp for displaying whether a network cable is plugged, and the test program is used for displaying the test result), so as to draw the attention of a tester.
For example, "switch port 2 forwards N packets to port 3," if the actual forwarding count for port 2 is 168750000000 and the actual forwarding count for port 3 is 168749999990, then port 3 has lost packets and port 3 performance does not meet the standard.
