portLoopbackTest 2 DIAGNOSTICS 8 -spd_mode mode 0 1 2 4 8 10 16 -ports itemlist Backend bypass & SERDES loopback (supported only on a chassis) Specifies the speed mode for the test. This parameter controls the speed at which each port is operated. The speed option chosen must not exceed the speed capability of the SFP device or the test will fail. For example, if you use an 8 Gbps SFP in a 16 Gbps-supported slot, you must use spd_mode 8 option to specify 8 Gbps speed. Runs test at 1 Gbps, 2 Gbps, 4 Gbps, and 8 Gbps on 8 Gbps ports. Runs test at 16 Gbps on 16 Gbps ports. Runs test at 1 Gbps (deprecated). Runs test at 2 Gbps. Runs test at 4 Gbps. Runs test at 8 Gbps (Default for 8 Gbps platforms). Runs test at 10 Gbps (Default for 10 Gbps platforms). Runs test at 16 Gbps (Default for 16 Gbps platforms). Specifies a list of blade ports to test. By default, all of the blade ports in the specified slot (--slot) are used. You must have root access to the bladePortMap command if you want to map a specific front-end blade port to a user port. See itemList for more information on the itemlist parameter. 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. TIMEOUT Did not receive a frame in the given timeout period. XMIT Frame transmission failure. Fabric OS Command Reference 777 53-1002746-01
