1.6.1.5.3 Configuring an agent to receive requests and send traps
This section describes how to configure SNMPv3 user information only. Additional configuration is required for
an SNMP agent to actually receive SNMP requests and send SNMP Traps.
When an SNMP agent receives an SNMPv3 request from an SNMP manager, the user sending the message must
be known to the agent’s SNMP engine. If the request is sent in a secure packet, the agent must use the use’s
security key to authenticate the message. For this operation, the keys must be pre-configured in the
snmpd.cnf con figuration file.
When an SNMP agent sends an SNMPv3 Trap to an SNMP manager, the recipient user must be known to the
agent’s SNMP engine. If the Trap is sent in a secure packet, the agent must use the user’s security key to com-
pute an authentication digest for the message. For this operation, the keys must be pre-configured in the
snmpd.cnf configuration file.
Note: For each the following examples, the snmpEngineID for the agent is used (localSnmpID),
because the receiving SNMP engine is authoritative for the security of SNMP request messages, and the
sending SNMP engine is authoritative for the security of SNMP Trap messages.
1.6.1.5.4 Configuration for authentication
The following usmUserEntry configures an SNMP agent engine with information about an SNMPv3 user
whose name is “myV3AuthNoPrivUser”. This entry contains the user’s authentication password. An SNMP
