Note: Enter commands in lowercase only; mixed case is for readability. portLoopbackTest 2 Examples -nframes count -lb_mode mode -spd_mode mode -ports itemlist 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. Specify the loopback mode for the test. By default, this test uses internal loopback. Valid values are as follows: 1 Port Loopback (loopback plugs) 2 External (SERDES) loopback 5 Internal (parallel) loopback Specify the speed mode for the test. This parameter is used only with Bloom and Condor ASIC-based products, where it controls the speed at which each port is operated. For 1 Gbit/sec-only products, it is ignored. The exact operation of speed 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 will fail. 0 Runs test at 1 Gbit/sec, 2 Gbit/sec, and 4 Gbit/sec. 1 Runs test at 1 Gbit/sec. 2 Runs test at 2 Gbit/sec (Bloom default). 4 Runs test at 4 Gbit/sec (Condor default). For lb_mode set to 0 or 1, the following speed modes are available to test the speed negotiation: 3 Set all even ports' speed for autonegotiate; set all odd ports' speed for 1 Gbit/sec. 4 Set all even ports' speed for autonegotiate; set all odd ports' speed for 2 Gbit/sec. 5 Set all odd ports' speed for autonegotiate; set all even ports' speed for 1 Gbit/sec. 6 Set all odd ports' speed for autonegotiate; 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. 3,5 Set all even ports' speed for 2 Gbit/sec; set all odd ports' speed for 1 Gbit/ sec. 4,6 Set all even ports' speed for 1 Gbit/sec; set all odd ports' speed for 2 Gbit/ sec. Specify 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. To run a functional test of a connection: switch:admin> portloopbacktest -ports 1/10-1/20 -nframes 1 -lb_mode 1 Running Port Loopback Test .... passed.
