Purpose:
This article will walk-through the steps required to enable SNMPv3 on Versa Director(10.192.219.100) and Analytics(10.192.12.125) running 18.04.
Configuration Steps:
Enabling SNMPv3 polling on Versa Director and Analytics requires tweaking on the SNMPD configs in the Ubuntu shell. The following steps will help to enable polling and the configuration is same on both Director and Analytics.
1. Modify the /etc/snmp/snmpd.conf file to listen on the address & port 161
####Change the agentAddress section to listen on the Northbound IP address####
agentAddress udp:10.192.219.100:161
#############
2. ADD/Create Users along with password that will be used by the SNMP poller for polling in the /etc/snmp/snmpd.conf file.
####Add the below user with bootstrap at the end of the file####
createUser bootstrap MD5 Lab1234@ DES
#############
3. Add Access-Controls permissions for the above user under Access-Control section in /etc/snmp/snmpd.conf as below.
####Assign read-write permissions for the bootstrap user####
rwuser bootstrap priv
#############
4. Restart the snmpd service.
#############
sudo service snmpd restart
#############
Verification:
Perform a SNMPv3 WALK/GET/BULKGET from the SNMP poller machine. Use the below command with the above user and credentials.
