System and method for testing network equipment mac address capacity

Abstract

The present invention relates to the field of data communication, which discloses a network equipment MAC address capacity testing system and method, which solves the problem that the test scheme in the traditional technology cannot test the network equipment with unknown maximum MAC address capacity, wastes port resources and low test efficiency, and builds automation cumbersome process. In the present invention, first configure the ACL rule for the network device under test so that it has the function of filtering unknown layer 2 unicast traffic, and then send known unicast traffic through a port of the test device so that the network device under test can learn the MAC address , and then send verification traffic through another port of the test device. The traffic of the excess discarded MAC address is the MAC address that the network device under test has not learned, and the traffic that is forwarded is the MAC address that the network device under test has learned. , the MAC address capacity of the network device under test can be calculated by counting the size of the passing traffic at the port of the test device.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a system and method for testing the MAC address capacity of network equipment. Background technique [0002] The MAC address (media access hardware address) of the switch is stored in the cache of the switch, that is, the MAC address table, which is used to identify each node passing through the switch, which includes parameters such as MAC address, VLAN ID, and port number. When a port receives After receiving the message, the MAC address table can be used to look up the VLAN and outgoing port corresponding to the MAC address, so as to forward the message to the node. At present, the storage of the MAC address of the switch device is carried out in a hash table structure. When the MAC address table has learned a large capacity of MAC addresses, a hash collision may occur, causing the packet to be flooded and forwarded or discarded. [0003] Switch products are deployed in a la...
