2 Note: Enter commands in lowercase only; mixed case is for readability. txdPath Note The execution of this command is subject to Admin Domain restrictions that may be in place. Operands This command has the following operands: --slot slotnumber Specifies the slot number on which the diagnostic operates. 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 Specify the number of million frames to send. The test progresses until the specified number of frames has been transmitted on each port. The default value is 10, so the number of frames sent are at least 10 million. -lb_mode mode Specify the loopback point for the test. By default, this command uses loopback plugs, as described earlier. However, for debug purposes, you can select other loopback modes, as follows: 1 Port loopback (loopback plugs) 2 External (SERDES) loopback 5 Internal (parallel) loopback -spd_mode mode Specify the speed for the test. This parameter is used only for Bloom and Condor ASIC-based products, where For 1 Gbit/sec-only products, this option is ignored. The exact operation of modes 5 through 8 depends upon the loopback mode selected. When speed modes 5 through 8 are used with cables, they must be connected even to odd or the test fails. Modes include: 0 Run test at 1 Gbit/sec, 2 Gbit/sec, and 4 Gbit/sec (default). 1 Set all port speeds to lock at 1 Gbit/sec 2 Set all port speeds to lock at 2 Gbit/sec. 4 Set all port speeds to lock at 4 Gbit/sec. For -lb_mode set to 0 or 1, the following speed modes are available to test the speed negotiation: 5 Set all even ports' speed for auto-negotiate, set all odd ports' speed for 1 Gbit/sec. 6 Set all even ports' speed for auto-negotiate, set all odd ports' speed for 2 Gbit/sec. 7 Set all odd ports' speed for auto-negotiate, set all even ports' speed for 1 Gbit/sec. 8 Set all odd ports' speed for auto-negotiate, set all even ports' speed for 2 Gbit/sec. For -lb_mode set to 2 or 3, the following speed modes are available to test FIFO underrun. 5,7 Set all even ports' speed for 2 Gbit/sec, set all odd ports' speed for 1 Gbit/ sec. 6,8 Set all even ports' speed for 1 Gbit/sec, set all odd ports' speed for 2 Gbit/ sec. 2-716 Fabric OS Command Reference Manual Publication Number: 53-1000240-01
