Common Problems

Help ! I dont have any SNMPv3 users configured. Where do I start ?

For those new to SNMPv3 this may sound strange - "You need atleast one SNMPv3 user preconfigured before you can create others". The next question is - "Well, then how do I create the first user ?". This is dependent on your network element.

For instructions for configuring Cisco equipment see (Configuring SNMPv3 on Cisco)
For Net-SNMP configuration see (Net-SNMP Create Users) Note : If you are trying to use Net-SNMP you may need to apply our patch to get it to work. See our blog for details.

Should there be any special rights for the initial user ?

Yes, the initial user must have full read/write access atleast to the security portion of the MIB tree (the USM MIB and the VACM MIB). For example in Cisco IOS you would typically use :

snmp-server view myAdminView 1.3.6.1.6.3.16 included
snmp-server view myAdminView 1.3.6.1.6.3.18 included

What should I do with SNMPv2 community strings ?

We recommend that you get of SNMPv2 altogether once you have SNMPv3 up and running. Using shortcuts such as the com2sec directives to map SNMPv2 community strings to valid SNMPv3 security groups defeats the very purpose of moving to SNMPv3. See here how to disable community strings in Cisco gear (Disable SNMP community strings)
