slTest 2 slTest Tests the serial link of port N->N path. Synopsis sltest [-ports itemlist][-lb_mode mode][-speed mode][-passcnt count] Description Use this command to verify the intended functional operation of the switch by sending SERDES BIST patterns from port N's transmitter, and looping the patterns back into the same port N's receiver. The loopback is done at the parallel and serial loopback paths. The path exercised in this test can include the media or the fiber cable. The test patterns are transmitted and received continuously during the test duration. An external cable is optional to run this test. The test method is as follows: 1. Set all ports present for one of the following modes: parallel, SERDES pads, or external cable loopback. 2. Program the port to repeatedly send predefined LPE. 3. Verify the primitive is received at the same port. 4. Check the receive port for possible code violation on nonframe data or BadOrdSet. 5. Repeat steps 2 through 4 for all ports present until: a. The number of -passcnt count requested is reached. b. All ports are marked bad. This command is being deprecated and retained for legacy reasons only. On new 4G and 8G platforms, this command returns a "Command not applicable to this platform" message. The execution of this command is subject to Admin Domain restrictions that may be in place. Operands The optional operands are as follows: -lb_mode mode Sets the loopback point for the test. By default, slTest uses internal 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 -speed mode Specifies the speed mode for the test. 1 Runs the test at both 1 GBit/sec 2 Sets and locks all port speeds to 2 GBit/sec 3 Sets and locks all port speeds to 3 GBit/sec 4 Sets and locks all port speeds to 4 GBit/sec (default) -ports itemlist Specifies a list of blade ports to test. Specify the slot number followed by a slash (\) on bladed systems. By default, all the blade ports in the specified slot is used. Fabric OS Command Reference 589 53-1000599-01
