Problems solved by technology

[0006] Therefore, according to the general test standard requirements, it takes 6 hours to test the throughput rate of only one Ethernet switch interface, and it will take longer to fully test the throughput rate, packet loss rate and delay of all interfaces. The time cost is very high, and the development and production cycle of the equipment will also be delayed
Although a large Ethernet tester with multiple ports (20 ports or above) can test a large number of interfaces at the same time, this type of instrument is not commonly used, and the composition is very high, which is not suitable for most Ethernet switch manufacturers. Reality

Embodiment 1

[0032] Take the most common 24-port Gigabit electrical interface switch on the market as an example.

[0033] Define the interface number as 1-24, divide 12 VLANs, each VLAN number and the interface in the VLAN group are:

[0034] VLAN1 includes interface 1 and interface 2;

[0035] VLAN2 includes interface 3 and interface 4;

[0036] VLAN3 includes interface 5 and interface 6;

[0037] VLAN4 includes interface 7 and interface 8;

[0038] VLAN5 includes interface 9 and interface 10;

[0039] VLAN6 includes interface 11 and interface 12;

[0040] VLAN7 includes interface 13 and interface 14;

[0041] VLAN8 includes interface 15 and interface 16;

[0042] VLAN9 includes interface 17 and interface 18;

[0043] VLAN10 includes interface 19 and interface 20;

[0044] VLAN11 includes interface 21 and interface 22;

[0045] VLAN12 includes interface 23 and interface 24;

[0046] Use a network cable to loop back the interfaces except interfaces 1 and 24 in twos in sequence, ...

Abstract

The invention discloses an efficient interface testing method for an Ethernet switch. The method comprises the following steps: 1) the interface quantity of the switch is defined as n, and the interface numbers are defined as E1, E2, E3...En; 2) every two interfaces belong to a VLAN (Virtual Local Area Network), namely, E1 and E2 belong to a VLAN1, E3 and E4 belong to a VLAN2, E5 and E6 belong to a VLAN3, E7 and E8 belong to a VLAN4, and the like, E(n-1) and En belong to a VLAN(n / 2); 3) E2 and E3, E4 and E5, E6 and E7...E(n-2) and E(n-1) are respectively connected with each other by a cable in sequence; 4) except E1 and En, each two of all the rest interfaces are subjected to loopback in sequence, and E1 and En are connected with an Ethernet testing instrument to be tested. As nearly all large switches support the interface VLAN division, the method has the beneficial effects that the configuration is simple, and the operation is convenient; under the condition that the cost of the testing instrument is not increased, the testing time can be greatly saved.

Description

technical field [0001] The invention relates to a method for testing an interface of an exchange, in particular to an efficient method for testing an interface of an Ethernet exchange, and belongs to the technical field of computer communication. Background technique [0002] With the development of the network, the versatility and efficiency of the network are becoming more and more obvious, and its application in all walks of life is also increasing, and it is more closely related to our daily work and life. The popularity of the network leads to more and more use of Ethernet switches, especially large Ethernet switches with a large number of Ethernet interfaces are used more and more frequently in various industries. [0003] As the number of Ethernet switches used increases, the time required for testing and detection of the related Ethernet switches will increase accordingly. Especially for Ethernet switches with many interfaces, since all ports need to be covered when...
