snmpcmd(1), under "Generic Options", it says,
-D[TOKEN[,...]] Turn on debugging output for the given TOKEN(s). Try ALL for extremely verbose output.
What tokens could I use besides
ALL? What do the tokens mean? The tools are very liberal about what tokens they will accept.
$ snmpgetnext -Dserverfault_is_awesome [...] registered debug token serverfault_is_awesome, 1 [...]
The best thing I have found so far is a wiki page talking about v188.8.131.52, but it does not address the general problem of listing debug tokens that are valid for the currently installed version (5.7.2 in my case).
