Step 6 The detail display output provides the following information:
• Check the Trace Result field. It should indicate the Trace Completed Normally.
• The Node Incoming and Outgoing VPI and VPI numbers provide the VCs for each node in the
connection trace.
• The hexadecimal Call-ref and Endpt-ref numbers might be helpful matching the same numbers to
previously received debug or error messages.
