2 miniCycle d. 200 bytes of RANDOM 5. Periodically check status... a. Each port has not died. b. Each port's frames-transmitted counter is still incrementing. c. Each port's statistic error counters are nonzero: ENC_in, CRC_err, TruncFrm, FrmTooLong, BadEOF, Enc_out, BadOrdSet, DiscC3 6. ...until one of the following is met: a. The number of frames requested is met on all selected ports. b. All ports are eventually marked bad. c. The user aborts the procedure. The path test is repeated for each path, unless it is aborted by a keyboard interrupt. The data is not read and checked as in the portLoopbackTest. There is no CPU intervention during a path test besides the periodic checks of the hardware counters. At the end of a path test, all statistics and routes are reset for the next path test. An example of the data used is as follows: CSPAT: RDRAM_PAT: BYTE_LFSR: RANDOM: 0x7e, 0x7e, 0x7e, 0x7e, ... 0xff, 0x00, 0xff, 0x00, ... 0x69, 0x01, 0x02, 0x05, ... 0x25, 0x7f, 0x6e, 0x9a, ... Because this test includes the media and the fiber cable loopback plug in its test path, its results combined with the results of portLoopbackTest can determine, which components of the switch are faulty. Operands The following operands are optional: --slot slotnumber Specifies the slot number the diagnostic will operate on. The ports specified are relative to this slot number. The default is set to 0 and designed to operate on fixed port-count products. -nmegs count Specifies the number of million frames to send per path test. The path test will progress until the specified number of frames has been transmitted on each port. The default value for count is 1, so the total number of frames sent will be at least 8 million (1 million frames * 8 paths). -lb_mode mode Specifies the loopback point for the test. By default, miniCycle uses external (SERDES) loopback. 1 Port Loopback (loopback plugs) 2 External (SERDES) loopback 5 Internal (parallel) loopback 7 Backend bypass and port loopback 8 Backend bypass and SERDES loopback 9 Backend bypass and internal loopback 332 Fabric OS Command Reference 53-1000599-01
