Enabling SNMPv3

SNMP v3 security is enabled and configured globally for all agents configured in the Nextian SNMP Agent Simulator.

Multiple SNMPv3 security profiles can be defined (e.g., with various usernames and passwords and/or encryption), however they will apply to all the agents as well.

To enable SNMP v3:

  1. Edit simulator.conf file as Administrator (Windows) or root (Linux):

    Windows %SYSTEMROOT%\etc\nextian.d\simulator.conf

    Linux /etc/nextian.d/simulator.conf

  2. Create or uncomment at least one security entry (each entry defines a single profile), at the bottom of the file: 
    SECURITY_ENTRY1=public:SHA:password:DES:password

    Please read comments in simulator.conf for detailed information about entry syntax.

  3. Restart the simulator:

    Windows Restart the windows service

    Linux sudo systemctl restart nextian-snmpsimulator

  4. SNMP-walk the agent: 
    snmpwalk -v3 -a SHA -A "password" -x DES -X "password" -u public -l authPriv localhost:163
