However, if each port is started randomly, the test scenario cannot be reproduced, and the results of each test may be different; in addition, it is impossible to completely avoid the situation that multiple ports send traffic to a certain destination port at the same time

Abstract

The invention discloses a tester and an Ethernet test method of a multiport tested device. The method comprises the following steps: the tester schedules a destination port which is about to send a test data packet in ports connected with the tested device according to the following principle: no more than one test data packet of the ports is sent to the same destination port at the same moment; each port sends the test data packet to all ports excluding the port connected with the present port of the tested device in a polling manner; and the tester controls the ports to send the test data packets synchronously according to the scheduling result. By application of the Ethernet test method disclosed by the invention, the situation that a plurality of ports send flow to a certain destination port at the same time, resulting in test failure or abnormality, is avoided.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a tester and an Ethernet test method for multi-port tested equipment. Background technique [0002] Ethernet testing is guided by some international standards and norms, such as RFC2544 and RFC2889. Manufacturers of switches and routers need to test the produced equipment according to these international test standards before leaving the factory. RFC2544 is one of the most basic test guidelines, which defines the full mesh (full mesh) test, which is used to verify the port bandwidth utilization capability of the port of the switching device when forwarding multiple network traffic. The many-to-one (many-to-one) test defined in RFC2889 is also based on the same test purpose. [0003] The devices under test for the full mesh test generally involve more ports, such as 24-port switches and 48-port switches. Correspondingly, 24 or 48 ports of the tester are required to genera...
