Description
Use this command to verify the functional operation of the switch. This command
verifies operation by sending frames from a port M’s transmitter and looping the
frames back through an external fiber cable into another port N’s receiver. This
exercises all of the switch components from the main board to the SFP, from the
SFP to the fiber cable, from the fiber cable to the SFP, and from the SFP back to
the main board.
With the lb_mode operand set to 1 it is also possible to test ports with loopback
plugs that connect each port back to itself.
The cables can be connected to any port combination as long as the cables and
SFPs connected are of the same technology. For example, a short wavelength SFP
port is connected to another short wavelength SFP port using a short wavelength
cable, or a long wavelength port is connected to another long wavelength port, and
a copper port is connected to a copper port.
For complete testing, ports connected should be from different ASICs.
Only one frame is transmitted and received at a given time. The port LEDs flicker
green rapidly while the test is running.
