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
The present invention relates to a kind of exchange interface method of testing, specifically a kind of Ethernet switch interface test method efficiently, belongs to computer communication technology field.
Background technology
Along with the development of network, the multifunctionality of network and high efficiency are more and more obvious, and its application in all trades and professions also gets more and more, and contact tightr with our schedule work and life.The universal of network causes the use of Ethernet switch also to get more and more, and particularly the use of a fairly large number of large-scale Ethernet switch of Ethernet interface in industry-by-industry is more and more frequent.
Increasing of Ethernet switch usage quantity, associated Ethernet switch test will increase with the time needed for detecting thereupon.The Ethernet switch that particularly interface is more, owing to needing to cover all of the port during test interface, the time resource that needs take is very many.
With general testing standard requirement, test Ethernet throughput, needs the Ethernet bag of 7 kinds of bag length of testing within the scope of 64-1518, long 1 minute of each bag, repeat three times, add the time of instrument to auxiliary data transmission, calculating, once test required time general 30 minutes.Further, this is only the test of a throughput, and loss packet test and delay test time can be longer.When needs traversal all of the port, a large amount of time will be taken.
The ethernet test instrument used in prior art mostly is four test interfaces, eight test interfaces or more little.For an ethernet test instrument with four test ports, if directly will test the total interface of 48 mouth switchs, each test 4 interfaces, then need to carry out ten second tests.
Therefore, with general testing standard requirement, only test the throughput of an Ethernet switch interface, just need test 6 hours, count the interface throughput that Complete test is all in, packet loss and time delay, the time can be longer, cause time cost very high, also can postpone the Development and Production cycle of equipment.Use the large-scale ethernet test instrument of many mouthfuls (20 mouthfuls or more), although can test a large amount of interfaces simultaneously, this quasi-instrument uses general, and composition is very high, unrealistic for most Ethernet switch manufacturer.
Summary of the invention
Have problems for above-mentioned prior art, the invention provides a kind of Ethernet switch interface test method efficiently, the method utilizes the functionality of vlan of switch, come through loopback test between port and once just can cover all of the port, namely all interface throughputs can be tested, the time resource needed in turn saving test and detecting.
The present invention is achieved through the following technical solutions above-mentioned purpose: a kind of Ethernet switch interface test method efficiently, the method comprises the steps:
1), definition exchange interface quantity is n, and interface number is defined as E1, E2, E3 ... En;
2), in order, every two interfaces are divided into a VLAN, and namely E1, E2 are divided into VLAN1, E3, E4 are divided into VLAN2, E5, E6 are divided into VLAN3, and E7, E8 are divided into VLAN4, the like be divided into VLAN (n/2) to En-1, En;
3), by netting twine successively by E2 and E3, E4 and E5, E6 and E7 ... En-2 and En-1 couples together;
4), except E1 and En interface, all loopbacks between two in order, and by E1 and En two interface access network based on ethernet testers tests.
Further, described exchange interface quantity n is even number.
Further, described exchange interface quantity n is odd number, then last interface number En can not participate in loopback test, needs to test separately.
Further, described exchange interface is electrical interface, and network interface is connected and connected by netting twine.
Further, described exchange interface is optical interface, and Fiber connection is passed through in network interface connection.
Further, described exchange interface is between optical interface and electrical interface, and network interface connects by other model calling of transferring.
The invention has the beneficial effects as follows: how the solution that the method can be concrete utilizes divides VLAN to switch ports themselves, and passes through the mode of loopback between port, can disposable test all of the port.Save the cost of testing time, the Development and Production cycle of equipment can not be postponed.Because nearly all larger switch all supports that port vlan divides, and is operated by the method, configuration is simple, easy to operate; When not increasing tester cost, the testing time can greatly be saved.
What the method divided that VLAN mainly utilizes to switch ports themselves is mutually isolated between the different broadcast domains that divide of VLAN, and the communication of isolation different group vlan port, avoids causing test crash to forming broadcast storm between individual port during loopback.
Embodiment
Below in conjunction with embodiments of the invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
