Embodiment Construction

[0044] The method for testing the aging time of the MAC address table of the RPR network equipment provided by the present invention firstly sets up a ring topology composed of 3 RPR network nodes S1, S2, and S3, as shown in Figure 2; then, press as follows Steps to test:

[0045] (1) Configure a common ring-up service (priority of A, B, and C) for S1, S2, and S3 node devices, and configure these services as non-isolated services (that is, the three services have the same broadcast domain ), so that they can communicate with each other;

[0046] (2) The MAC address aging time T of the S1, S2, and S3 node devices is set on the network management;

[0047] (3) The test port 1 of the network tester sends a data frame to S1, and the sending flow is lower than the system bandwidth. Both test ports 2 and 3 receive the data frame (caused by the flooding of the initial network access), and record the time t1 at this time ;

[0048] (4) The test port 2 connected with S2 sends the un...

Abstract

An MAC address table aging time testing method. The present invention comprises the steps: a) common upper ring businesses are configured on the first, the second and the third node equipments in the RPR network topology, and the upper ring businesses have the same broadcast domain; b) the network tester in the RPR network topology transmits a data frame to the first node equipment through the first testing port, the second and the third testing ports of the network tester receive the data frame, and the time t1 is recorded; c) the second testing port takes the original address for the first testing port to send the data frame as the destination address continuous sending uicast fame, and the first testing port receives the uicast fame; d) when third testing port receives the unicast frame again, the time t2 the moment is recorded, the difference (t2-t1) f the t2 and the t1 is the measured MAC address table aging time. The method can accomplishes the whole testing during only one testing period, and the testing efficiency is improved.

Description

technical field [0001] The present invention relates to the parameter test technique of network equipment of flexible packet ring (RPR, Resilient PacketRing) of data communication metropolitan area Ethernet, especially relates to the test method of the aging time of the medium access control (MAC, Medium Access Control) address table of RPR network equipment. Background technique [0002] The RPR network device MAC address table is a table used by the RPR network device to store the source MAC address of the Ethernet data frame on the RPR ring and the corresponding node information on the ring (that is, into the ring). The data in this table provides the basis for data exchange between RPR network devices. For data frames that need to be forwarded on the RPR ring network, the device always searches the MAC address table first to find the RPR node information corresponding to the destination MAC address of the data frame, and then the device automatically forwards the data fr...
