Detailed description of the invention
Fig. 1 is network topological diagram of the invention.
Specific embodiment
The FC interchanger priority test method of offer of the invention is based on FC interchanger and FC-AE-ASM by building
The network topology of Node station composition, configures different communication plans to each FC-AE-ASM Node station, and wrong in communication process
It accidentally injects, realizes the uncertainty to the data forwarding of FC interchanger, big data quantity transmission is communicated busy and is likely to occur
The fault test of data communication under the extreme cases such as link failure.
The present invention is described in further details below.
A kind of FC interchanger priority test method, the network system formed based on FC interchanger and FC-AE-ASM Node station
System, comprising the following steps:
Step 1: network topology is arranged by FC interchanger and FC-AE-ASM Node station；
Step 2: test equipment JDSU tester being serially connected between PC machine and FC interchanger, JDSU analyzer is serially connected in
Priority is constituted between FC-AE-ASM Node station and FC interchanger tests environment；
Step 3: configuration JDSU tester sends priority, destination port, the transmission rate of data frame, simulates true application
Data communication under environment；
Step 4: evaluation and test priority test result.
Network topology is arranged by FC interchanger and FC-AE-ASM Node station in step 1, specifically:
FC interchanger is attached on FC-AE-ASM Node station according to the difference of port numbers, when connectivity port exchanges FC
The transmitting terminal of machine is connected with the receiving end of FC-AE-ASM Node station, the receiving end of FC interchanger and the hair of FC-AE-ASM Node station
Sending end is connected.
Test equipment JDSU tester is serially connected between PC machine and FC interchanger by step 2, and JDSU analyzer is serially connected in
Priority is constituted between FC-AE-ASM Node station and FC interchanger tests environment, specifically:
Test equipment JDSU tester is serially connected between PC machine and FC interchanger, under program, generating excellent
The configurable a variety of verifying frames for meeting FC-AE-ASM frame format of first grade, are motivated as verifying, by optical fiber, are input to FC friendship
The communication port changed planes completes the preferential level verification to FC interchanger；
JDSU analyzer is serially connected between FC-AE-ASM Node station and FC interchanger and constitutes priority test environment, is used
In under program control, the frame exported to FC exchanger chip communication port on witness plate is received, and parses, and is provided and is connect
Receive the result of the correction judgement of frame.
Step 3 configures priority, destination port, the transmission rate that JDSU tester sends data frame, simulates true application
Data communication under environment, specifically:
It configures JDSU tester and the identical list of priority is sent to the different communication port of FC interchanger simultaneously with line rate
Broadcast frame, multicast frames, broadcast frame, the D_ID configuration of frame is identical, test answer after five minutes, in received communication port first it is detected that
The broadcast frame of forwarding, then detect the multicast frames of forwarding, finally detect the unicast frame of forwarding.
Configure the unicast that JDSU tester sends low priority with line rate to a communication port of FC interchanger first
Frame sends the unicast frame of high priority to another communication port again after 1 minute, and the D_ID configuration of frame is identical, tests 5 points
Zhong Hou answers the unicast frame first it is detected that low priority in received communication port, then detects the unicast frame of high priority, low
Priority unicast frame will not be interrupted by high priority unicast frame.Unicast frame is changed to multicast frames, is repeated the above steps, should received
Communication port first it is detected that low priority multicast frames, then detect the multicast frames of high priority.
Step 4 evaluates and tests priority test result, specifically:
In purpose communication node and JDSU protocol analyzer the data of communication are carried out with the integrality of data format respectively
Monitoring, and data content and desired value are compared, to complete the test of FC interchanger priority.
