Fabric OS Commands Operands 6. Check if the transmit, receive or class 3 receiver counters are stuck at some value. 7. Check if the number of frames transmitted is not equal to the number of frames received. 8. Repeat steps 2 through 7 for all ports present until: - The number of frames (or passCount) requested is reached. - All ports are marked bad. At each pass, the frame is created from a different data type. If seven passes are requested, seven different data types are used in the test. If eight passes are requested, the first seven frames use unique data types, and the eighth is the same as the first. The seven data types are: 1) CSPAT: 0x7e, 0x7e, 0x7e, 0x7e,... 2) BYTE_LFSR: 0x69, 0x01, 0x02, 0x05,... 3) CHALF_SQ: 0x4a, 0x4a, 0x4a, 0x4a,... 4) QUAD_NOT: 0x00, 0xff, 0x00, 0xff,... 5) CQTR_SQ: 0x78, 0x78, 0x78, 0x78,... 6) CRPAT: 0xbc, 0xbc, 0x23, 0x47,... 7) RANDOM: 0x25, 0x7f, 0x6e, 0x9a,... Because this test does not include the media, SFP, or the fiber cable in its test path, use the results from this test in conjunction with the results from crossPortTest and spinSilk (both of which loop frames using an external loopback cable) test to determine those switch components that are not functioning properly. This command has the following operands: passCount (V3.1.x only) --slot number (V4.1.x only) -nframes count (V4.1.x only) Specify the number of times (or number of frames per port) to execute this test. The default value is 0xfffffffe. This operand is optional. Specify the slot number that the diagnostic will operate on. The ports specified will be relative to this slot number. The default is set to 0 and designed to operate on fixed port count products. Specify the number of frames to send. The test will progress until the specified number of frames has been transmitted on each port. The default value is 10. 588 Fabric OS Version 3.1.x/4.1.x Reference Guide
