SHOW FASTPATH (Alpha/I64 Only)

Displays fastpath port assignment and usage. SHOW FASTPATH is useful for evaluating the distribution of interrupts among the various CPUs in complex configurations.





Requests fastpath information for one or more specific CPUs. By default, information is displayed for all CPUs.



Controls where output from the command is sent. If you omit the /OUTPUT qualifier or omit the file specification with the qualifier, the display is written to the current SYS$OUTPUT device by default. If you enter the /NOOUTPUT qualifier, output is suppressed.
