2.2) the back pressure control register of configuration receiving node machine B, closes and replys R_RDY primitive functions, when Node station B is examined
It measures when FC interchangers send the frame of processing and does not reply R_RDY primitive；
2.3) content frame of configuration sending node machine A, it is ensured that frame can be normally sent to the receiving port 20 of FC interchangers.
Above-mentioned steps 3) it is as follows：
3.1) sending node machine sends 1 frame FC-ASM frames, and the FC MAC of the receiving port of FC interchangers, which can be read, to be connect
Receipts frame count is 0x1, and FC interchangers forward frame to sending port, and last receiving node machine receives 1 frame；
3.2) check whether the credit value of the sending port of current FC interchangers subtracts one, if so, enter step 4), if it is not,
Then test crash.
Above-mentioned steps 4) it is as follows：
4.1) after sending node machine continuously transmits n-1 frame FC-ASM frames, the sending port of FC interchangers receives n-1 frames, when
Preceding credit becomes 0x0, and receiving node machine receives n-1 frames；
4.2) Node station A retransmits a frame, and the sending port faithlessness time of FC interchangers is more than the setting time (1-
65535ms), FC interchangers are forced sending port offline, are at off-line state.
Above-mentioned steps 4) after further include step 5) restore FC interchangers sending port credit value, make its port again on
Line.
Above-mentioned steps 5) it is as follows：
5.1) it reaches the standard grade again enabled register after the link reset of configuration FC interchangers, its port is made to reach the standard grade again；
5.2) it is n that configuration credit, which restores register, and it is n to make current credit again, it is ensured that can normal receiving frame.
FC exchanger chips credit management test method provided by the invention is returned by closing the automatic of receiving node machine
Multiple R_RDY primitive, sending node machine do not receive the R_RDY primitive of receiving node machine reply when sending frame, and credit disappears every time
It consumes 1 and cannot compensate, after credit consumed is complete, port down.Ensure that the credit management of FC exchanger chips can be controlled effectively
Link flow processed.
