portLoopbackTest 2 Operands This command has the following operands: --slot number Specifies the slot number on which to run the diagnostics. The ports specified will be relative to this slot number. The default is 0 and designed to operate on fixed-port-count products. -nframes count Specifies the number of frames to send. The test progresses until the specified number of frames has been transmitted on each port. The default value is 10. -lb_mode mode Specifies the loopback mode for the test. By default, this test uses the internal loopback. Valid values are as follows: 1 Port Loopback (loopback plugs) 2 External (SERDES) loopback 5 Internal (parallel) loopback 7 Backend bypass & port loopback 8 Backend bypass & SERDES loopback (supported only on a chassis) -spd_mode mode 9 Backend bypass & internal loopback (supported only on a chassis) Specifies the speed mode for the test. This parameter controls the speed at which each port is operated. 0 Runs test at 1 Gbps, 2 Gbps, and 4 Gbps. 1 Runs test at 1 Gbps. 2 Runs test at 2 Gbps. 4 Runs test at 4 Gbps (Default for 4 G platforms). -ports itemlist 8 Runs test at 8 Gbps (Default for 8 G platforms). Specifies a list of blade ports to test. By default, all of the blade ports in the specified slot (--slot) are used. See itemList for more information on the itemlist parameter.

Diagnostics When it detects failures, the test may report one or more of the following error messages. If errors persist, contact Technical Support. DATA Data received does not match the data sent. ERRSTAT Errors were found in the ASIC statistics. INIT Port failed to initialize. PORTDIED A previously initialized port went to an uninitialized state. STATS Errors were found in the ASIC statistics. Fabric OS Command Reference 621 53-1001186-01
