   authCommunity log,execute,net public
   
   WHERE:
   "log" & "execute" are the actions to take
   "net redrock" is to listen for any traps with redrock as the community string

3) Start snmptrapd by:

   snmptrapd -Lf /var/log/snmptrapd.log -c /etc/snmp/snmptrapd.conf
   
   WHERE:
   "-Lf" is log to file /var/log/snmptrapd.log
   "-c" is use /etc/snmp/snmptrapd.conf as the config file.

4) Test:

   snmptrap -v 1 -c public localhost .1.3.6.1.6.3.1.1.5.3 localhost 2 0 ' ' 1.3.6.1.2.1.2.2.1.1 i 1
