Debug tokens
There are many debug tokens in Net-SNMP. Debug tokens are not assigned, and MIB authors may use any string they'd like for debug tokens. Because tokens are not assigned, there is no way for running code to generate the current set of tokens.
To generate a list of tokens for a particlar version of Net-SNMP, you can download the source and run the following command in the source directory:
find . -name "*.c" | xargs grep "DEBUGMSG[A-Z_]*(( *\"" | sed 's/^.*DEBUGMSG[A-Z_]*(( *\"\([^\"]*\).*/\1/' | sort -u
Some of these tokens will be found but not be used because they are inside a multiline comment.
There are lists of tokens for a few releases in the wiki:
Note that you do not have to specify a complete token. For example, if you specify -Ddump, you will get debug output for dumpH_recv, dumpv_recv and dumpv_send.
Some of the more interesting/common tokens (available in most releases) are :
agentx disman dumpv dumph exec init_mib mib_init mteTrigger parse-file parse-mibs perl read_config recv run smux snmp snmpd snmptls snmptrapd snmpusm snmpv3 tls transport trap usm usmUser vacm versioninfo
