XPVAL Line Test Error Messages
Error messages for the XPVAL line tests appear in inverse video at the
system console. Some errors allow the test to continue, so they may
scroll off the top of the terminal screen. Copy the error message
information for further diagnosis.
Error Message Categories
Errors from the XPVAL line tests fall into the following categories:
• Packet verification errors.
• Send and receive failures.
• Socket creation failures.
• Checksum errors.
• Miscellaneous errors.
Packet Verification Errors
Packet verification errors indicate problems with either the packet size
or the character received. Packet Verification Errors will not abort the
XPVAL line tests. Their error messages may scroll off the top of the
console terminal screen, preceding a “TCP TEST FAILED” or console
message. Packet verification errors are listed below:
MESSAGE: RECEIVE PACKET IS INCORRECT SIZE Expected nn
Bytes. Received mm Bytes.
CAUSE: Either message packet was partially lost, or “send” and
“receive” are not synchronized.
ACTION: Usually packets will resynchronize with the start of the next
segment of the test. However if errors continue for each packet, check
surrounding errors, then rerun the test. If problems continue, see
MESSAGE: RECEIVE PACKET NOT VERIFIED First Byte not verified
is: xx Should be: y, received: z.
CAUSE: Either byte in packet has changed (bit error) or packets are
unsynchronized.
ACTION: Usually packets will resynchronize with the start of the next
segment of the test.
However if errors continue for each packet, check surrounding errors,
then rerun the test. If problems continue, see Appendix B , “Submitting
an CR.”
