SNMP v1 v2 v3 diffcences beetwen config files

I'm learning about SNMP protocol. I wonder what changes in the configuration files can I make. What else can I add? How to distinguish between version 1 of 2c?

My snmpv1/v2c config file

rwcommunity  public
#trap
trapsink  localhost
authtrapenable  1

snmpv3 config file

createUser test MD5 "test12345" DES
rwuser  test
Solution

  • The Net-SNMP Agent supports all three versions of the SNMP protocol. The version 1 and 2c are using a community string for simple authentication. This string is a shared secret between the agent and NMS. The string is passed in clear text over the network however and is not considered secure.

    So from configuration perspective there are no differences between SNMPv1 and SNMPv2C.

    The rest of Net-SNMP Agent configuration parameters are described here: http://net-snmp.sourceforge.net/tutorial/tutorial-5/demon/snmpd.html
