608 Fabric OS commands
Tests the serial link of port N->N path.
Synopsis
sltest [ -ports itemlist ][ -lb_mode mode ][ -speed mode ]
[ -passcnt count ][ -duration count ]
Availability
admin
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.
Operands
The optional operands are as follows:
slTest
-lb_mode mode Sets the loopback point for the test. By default, slTest uses internal
loopback. Available modes are as follows:
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
9 Backend bypass and internal loopback
-speed mode Specifies the speed mode for the test. Available modes are as follows:
1 Runs the test at both 1 Gb/s
2 Sets and locks all port speeds to 2 Gb/s
3 Sets and locks all port speeds to 3 Gb/s
4 Sets and locks all port speeds to 4 Gb/s (default)
