       The fifth field, (fs_freq), is used for these  filesystems
       by the dump(8) command to determine which filesystems need
       to be dumped.  If the fifth field is not present, a  value
       of zero is returned and dump will assume that the filesys­
       tem does not need to be dumped.

       The sixth field, (fs_passno), is used by the fsck(8)  pro­
       gram to determine the order in which filesystem checks are
       done at reboot time.  The root filesystem should be speci­
       fied  with  a fs_passno of 1, and other filesystems should
       have a fs_passno of 2.  Filesystems within a drive will be
       checked  sequentially, but filesystems on different drives
       will be checked at the same time  to  utilize  parallelism
       available in the hardware.  If the sixth field is not pre­
       sent or zero, a value of zero is returned  and  fsck  will
       assume that the filesystem does not need to be checked.

Unless you use dump to backup your system then set the dump field to 0.
For passno the above is pretty self explanatory.
