In order to create additional users in SNMPv3, the /etc/snmp/snmpd.conf can be modified
using the createUser instruction:
createUser <user_name> <auth> <new_auth_password> <priv>
The access_mode for these users can be assigned as following:
<access_mode>user <user_name>
After saving the changes, the SNMP daemon must be restarted to apply them.
Alternatively, net-snmp-create-v3-user tool can be used after stopping the SNMP
daemon or the groups definition can be modified to create users. For that purpose, the
information from the mapping section in /usr/share/snmp/snmpd.conf can be used as a
reference to modify the /etc/snmp/snmpd.conf file.
7.2.2 SNMP Traps
The SNMP traps are synchronous notifications generated by the agent which are sent to
the manager. While in other SNMP communications, the manager actively requests inform-
ation from the agent, the traps are sent from the agent to the manager without being expli-
citly requested. SNMP traps enable an agent to notify the management station of
significant events by way of an unsolicited SNMP message. The SNMP traps include cur-
rent sysUpTime value, an OID identifying the type of trap and optional variable bindings. A
reference scenario where SNMP traps are used is shown below:
