The portLogDump command output (trace) is a powerful tool that is used to troubleshoot fabric
issues. The portLogDump output provides detailed information about the actions and
communications within a fabric. By understanding the processes that are taking place in the fabric,
issues can be identified and located.
The portLogDump command displays the port log, showing a portion of the Fibre Channel payload
and header (FC-PH). The header contains control and addressing information associated with the
frame. The payload contains the information being transported by the frame and is determined by
the higher-level service or FC_4 upper level protocol. There are many different payload formats
based on the protocol.
Because a portLogDump output is long, a truncated example is presented:
