DEVICE AND METHOD FOR TESTING NETWORK SWITCH

Abstract

A network switch testing device and a method for testing at least one network switch involve a central processing unit (CPU), an acceleration port that can be enabled with internal loopback and an access control list, and at least one transmission port connectable with at least one to-be-tested transmission port of the to-be-tested network switch(es). The acceleration port and the transmission port(s) are set to the same virtual local area network (VLAN). The CPU transmits at least one packet to the acceleration port. The acceleration port circulates therein the packet(s) through internal loopback and according to the access control list to make the packet(s) reach a predetermined line rate, and transmits the predetermined-line-rate-reaching packet(s) to the transmission port(s) through VLAN's flooding mechanism. The transmission port(s) transmits the predetermined-line-rate-reaching packet(s) to the to-be-tested transmission port(s). The CPU stops the transmission port(s) from transmitting the packet(s) when the testing time ends.
