Description
Technical field
The invention belongs to computer communication technology, relate to a kind of FC switch test of supervisor method.
Background technology
FC network possesses high bandwidth, low delay and the characteristic such as highly reliable, is highly suitable in the distributed real-time systems had higher requirements to transfer of data real-time and uses.
FC switch, as whole FC server parts, except possessing the data communication functions such as clean culture, multicast, broadcast, also possessing monitoring function, carrying out analyzing and positioning problem by catching transmitted data on network.FC switch monitoring function is realized by policing port, and each policing port has three kinds of monitoring modes all respectively, comprises input monitoring pattern, output monitoring pattern and message monitoring pattern.Under input monitoring and output monitoring pattern, policing port can be monitored the input data of certain port and the output data of certain port respectively; Under message monitoring pattern, policing port can be monitored multiple message id.
Current FC testing equipment is when testing the monitoring function of FC switch, can only identify fundamental errors information such as CRC, EOF polarity of received frame, whether the monitoring function of FC switch correctly can only rely on and manually judge, and cannot compare to reception content frame, there is very large defect.
Summary of the invention
For solving the problem, the invention provides a kind of FC switch test of supervisor method, supporting the test under the monitoring modes such as the input monitoring of FC switch, output monitoring and message monitoring.
Technical solution of the present invention is,
A kind of FC switch test of supervisor method, comprises the following steps:
1) testing software carries out initial configuration to test logic, and deploy content comprises monitoring mode, input monitoring port numbers, output monitoring port numbers and message id allocation list; Monitoring mode comprises input monitoring pattern, input monitoring pattern and message monitoring pattern;
2) test logic is according to deploy content, sends Frame, and be stored in by Frame in each switching port transmission buffering area separately by switching port to tested FC switch;
3) each switching port of test logic and each policing port receive the Frame of tested FC switch feedback, and are written to by the Frame received in each switching port and each policing port reception buffer zone separately;
4) each switching port of test logic and each policing port judge whether the Frame received exists crc error or EOF incorrect polarity respectively:
If existed, jump to step 6); Otherwise jump procedure 5);
5) comparison of Frame:
Test logic judges the monitoring mode of each switching port, selects the Frame of the corresponding Frame of exchange port buffer and the reception buffer zone of policing port to compare according to monitoring mode, judges whether consistent, if consistent, jump procedure 2), if inconsistent, jump procedure 6);
6) flow process terminates, and reports mistake.
Wherein, step 5) in, the concrete grammar of Frame comparison is as follows:
5.1) if the monitoring mode of switching port is in input monitoring pattern, step 5.2 is jumped to); If be in output monitoring pattern, jump to step 5.4); If be in message monitoring pattern, jump to step 5.6);
5.2) test logic obtains input monitoring port numbers according to deploy content;
5.3) test logic reads the output buffer Frame of this port numbers corresponding ports, and compares with the reception buffer zone Frame of policing port, judges whether identical, if different, jumps to step 6); Otherwise, jump to step 2);
5.4) test logic obtains output monitoring port numbers according to deploy content;
5.5) test logic reads the input block Frame of this port numbers corresponding ports, and compares with the reception buffer zone Frame of policing port, judges whether identical, if different, jumps to step 6); Otherwise, jump to step 2);
5.6) test logic obtains S_ID and the message id of this Frame, searches the message id allocation list of corresponding policing port according to message id; Judge whether hit, if hit, jump to step 5.7); Otherwise, jump to step 6);
5.7) test logic reads the input block Frame of corresponding ports according to S_ID, and compares with policing port buffer data; Judge whether identical, if different, jump to step 6); Otherwise, jump to step 2).
The advantage that the present invention has is:
(1) input monitoring to FC switch, output monitoring and message monitoring functional test can be completed;
(2) can mistake be detected and automatically report, judging without the need to manual observation;
(3) can compare to content frame;
(4) be easy to FPGA realize, realize simple, be beneficial to the low-power consumption of testing equipment, miniaturization, be easy to carry.
