Viewing the Port Log
9
To view the port log
1. Connect to the switch and log in as admin.
2. Enter the portLogShow command:
Use the commands summarized in Table 9-2 to view and manage port logs.
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.
