Diagnostic Features Link errors Once the frame is sent out of the port, the spinFab command monitors the link errors in the ASIC. If any of the error counters are nonzero, spinFab reports an error and the test fails on the port.

You should first clear all error counters and rerun the spinFab command. ∙ Verify that the link comes up by enabling and disabling the local or remote ports. ∙ Verify that the source of the error is either the local port or the remote port. This can be done by monitoring the port statistics on both ends simultaneously. Refer to Displaying the port statistics on page 91 for more information on how to display the statistics for a port. ∙ Verify that the cables and SFPs are inserted properly. Remove and insert them again on both ends. ∙ Verify that the failing local port is working when connected to another remote port. Similarly, check whether the failing remote port is working when connected to another local port. ∙ Once the fault is isolated on either the local port or the remote port, replace the cable and SFPs connected to the local port and the remote ports. ∙ In case of loopback ports, change the loopback plug. Refer to Marginal links on page 41 for more information on changing the loopback plug. ∙ Further isolation can be done by running the portLoopbackTest command (Offline test) on the failing port to check whether the blade internal ports are having some problems. - The -lb_mode 1 operand verifies that the SFP is working within normal operating parameters. The use of this operand requires that loopback cables are connected. - The -lb_mode 2 verifies that the ASIC port is working within normal operating parameters. The use of this operand does not require any loopback cables. Tx/Rx errors The following errors are seen when the port fails to transmit or receive the frames.
