Check All Switch Components Of The Port Transmit And Receive Path - HP StorageWorks MSA 2/8 - SAN Switch User Manual

Check all Switch Components of the Port Transmit and Receive Path

The following procedure exercises all the switch components from the main board
--> SFP --> fibre cable --> back to SFP --> back to main board.
1. Make sure all cables used for connected port and SFPs are of the same
2. Connect ports from different ASICs, if possible (for example, connect port 1
3. Log into the switch as admin.
4. Enter switchdisable if the switch should assume all ports are cable
5. (Optional) Enter setsfpmode to limit the test to ports with that contain
6. Enable the ports for cabled loopback mode by entering crossporttest
7. Create a frame F of maximum data size (2112 bytes).
8. Transmit frame F through port M.
9. Pick up the frame from its cross-connected port N. An error is reported if any
10. Determine if any of the following statistic error counters are non-zero:
11. Determine if the transmit, receive, or class 3 receiver counters are stuck at a
12. Determine if the number of frames transmitted is not equal to the number of
13. Determine if the number of frames transmitted is not equal to the number of
