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. Note This command is supported only on SilkWorm 200E,4100, 4900, and 48000 platforms. Note 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) 2-620 Fabric OS Command Reference Manual Publication Number: 53-1000240-01
