Check All Switch Components Between Main Board, SFP, and Fiber Cable

The following procedure exercises all the switch components from the main board
--> SFP --> fiber cable --> SFP on the device --> back to main board.
1. Make sure all connected cables and SFPs are of the same technology (that is a
2. Log into the switch as admin.
3. Determine which ports are L-Ports by entering the switchshow
4. Enable ports for loopback mode by entering loopporttest
5. Create a frame F of data size (1024) bytes.
6. Transmit frame F via port M, with D_ID to the FL port (AL_PA = 0).
7. Pick up the frame from port M, the FL port.
