Neither.
"proc" and "procfix" don't actually trigger traps at all.
At least not on their own - that's the realm of the (newer)
"monitor" directive.

The basic use of "proc" is to set a flag when it detects an
error.  It's up to an external management application to poll
the agent to spot such error flags.

The basic use of "procfix" is to run a command when it is
explicitly told to do so (by some external management app).
This command will *not* be run automatically (at least not
on its own), or trigger a trap - either before or after
being run.



One possibility with the 5.3 release is to have the DisMan
Event MIB trigger a suitable SET request (instead of sending
a trap), that *will* execute the command automatically.

This would look something as follows (untested!):

    setEvent jimllFixIt  prErrFix = 1
    monitor -S -r 128 -e jimllFixIt "procTable" prErrorFlag != 0


This functionality is only available with the 5.3 release.
The previous Event MIB implementation did not support set
events, just notifications.
