[0004] At present, the MAC address learning rate of network equipment is usually tested based on the formula V=M / T, wherein M refers to the test MAC address capacity, T refers to the time consumed to learn the MAC address, and V is the MAC address learning rate. , the test methods based on this formula are more dependent on time T, and time T is easy to bring errors, so that the final MAC address learning rate has a large error and is not accurate enough

The invention provides a method for testing MAC address learning rate and a test system. A control terminal binds a static MAC address to a verification port of a to-be-tested device; then, a tester is controlled to send a learning flow sample and a verification flow sample to the to-be-tested equipment at a preset sending rate; when the third port of the tester is checked to have no flooding flowany more; and after waiting for a preset time, if the accumulated received flooding number of the third port is not increased, determining the accumulated received flooding number as a first floodingsample number, and then performing calculation based on the first flooding sample number, the flow number and a preset verification rate to obtain an MAC address learning rate. Because no time variable exists in the process, test errors caused by the time variable can be eliminated, and meanwhile, the method is suitable for testing the learning rate of the equipment to be tested when MAC addresslearning is carried out in a software mode or a hardware mode, and has universality.
Description
technical field [0001] The invention relates to the field of data processing, in particular to a method and a test system for testing a MAC address learning rate. Background technique [0002] In the environment of Layer 2 data forwarding, the network device needs to learn the MAC address first, and find the forwarding port corresponding to the MAC address. When a network device obtains a certain frame, if the destination address of the frame is the MAC address learned by the network device, the network device can unicast the frame to the port corresponding to the destination address according to the learning result; if the destination address of the frame If the address is not the MAC address learned by the network device, the network device will broadcast the frame to all ports except the port that received the frame, causing flooding. When there is a large amount of flooding in the environment, it will occupy the network device bandwidth. [0003] Therefore, it is neces...
