Abstract: A network switch testing device and a method for testing at least one network switch involve a central processing unit (CPU), a first acceleration port, a second acceleration port, and at least one transmission port connectable with at least one to-be-tested transmission port of at least one to-be-tested network switch. The first and second acceleration ports and the at least one transmission port are set to the same virtual local area network (VLAN). The CPU transmits at least one packet to the first acceleration port. The first and second acceleration ports use internal loopbacks and VLAN's flooding mechanism to make the packet(s) reach a predetermined line rate, and transmit the predetermined-line-rate-reaching packet(s) to the at least one transmission port. The at least one transmission port transmits the predetermined-line-rate-reaching packet(s) to the to-be-tested transmission port(s), and the CPU stops the transmission port(s) from transmitting the packet(s) when the testing time ends.
