12 Syslogd configuration TABLE 18 Commands for port log management (Continued) Command Description portLogDump portLogEnable portLogShow Display port logs for all or particular ports, without page breaks. Enable port logs for all or particular ports. Display port logs for all or particular ports, with page breaks. 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: brcd300:admin> portlogdump time task event port cmd args Fri Feb 22 20:29:12 2008 20:29:12.638 FCPH write 3 40 00fffffd,00fffffd,00000000,00000000,00000000 20:29:12.638 FCPH seq 3 28 00300000,00000000,000005f4,00020182,0000000 20:29:12.638 PORT Tx 3 40 02fffffd,00fffffd,09a5ffff,14000000 20:29:12.638 FCPH write 9 40 00fffffd,00fffffd,00000000,00000000,00000000 20:29:12.638 FCPH seq 9 28 00300000,00000000,000005f4,00020182,00000000 20:29:12.639 PORT Tx 9 40 02fffffd,00fffffd,09a6ffff,14000000 20:29:12.639 PORT Rx 3 0 c0fffffd,00fffffd,09a50304,00000001 20:29:12.640 PORT Rx 9 0 c0fffffd,00fffffd,09a60305,00000001 20:29:20.804 PORT Rx 9 40 02fffffd,00fffffd,0306ffff,14000000 20:29:20.805 PORT Tx 9 0 c0fffffd,00fffffd,030609a7,00000001 20:29:20.805 FCPH read 9 40 02fffffd,00fffffd,d1000000,00000000,030609a7 20:29:20.805 FCPH seq 9 28 22380000,030609a7,00000608,0000001c,00000000 20:29:20.805 PORT Rx 3 40 02fffffd,00fffffd,02eeffff,14000000 20:29:20.806 PORT Tx 3 0 c0fffffd,00fffffd,02ee09a8,00000001 20:29:20.806 FCPH read 3 40 02fffffd,00fffffd,d2000000,00000000,02ee09a8 20:29:20.806 FCPH seq 3 28 22380000,02ee09a8,00000608,0000001c,00000000 20:29:32.638 FCPH write 3 40 00fffffd,00fffffd,00000000,00000000,00000000 20:29:32.638 FCPH seq 3 28 00300000,00000000,000005f4,00020182,00000000 20:29:32.638 PORT Tx 3 40 02fffffd,00fffffd,09a9ffff,14000000 20:29:32.638 FCPH write 9 40 00fffffd,00fffffd,00000000,00000000, 00000000 20:29:32.638 FCPH seq 9 28 00300000,00000000,000005f4,00020182,00000000 20:29:32.639 PORT Tx 9 40 02fffffd,00fffffd,09aaffff,14000000 Syslogd configuration The system logging daemon (syslogd) is an IP-based service for logging system messages made available by default on Unix and Linux operating systems.
