Use the commands summarized in Table 22 to view and manage port logs. Refer to the Fabric OS
Command Reference for additional information about these commands.
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:
