It's been a long while for me with SNMP, but are you perhaps trying to access something in a private versus public MIB and this is why it wants a username? And I'm not even sure if the difference of private vs. public mattered there as opposed to the simple fact that the private MIB is just proprietary. I think some more details about what you're doing, what version of net-snmp you have, and a cut/paste of your command attempt and error might be helpful.

After a brief search: it would be the Community String concept, but that's for v1/v2 and it says for v3 they went to username/password. So you need to know that information to be able to access the objects on that particular tree.

I am facing a problem in configuring snmp v3 using net-snmp in both Windows and Linux(RHEL). But snmp v1 and snmpv2 are working fine.
I investigated a lot by seeing websites, forums and the email that you sent. Still I couldn’t find a solution.
If you have already faced same kind of problem please share the information with us. It helps us to resolve this problem.

Net-snmp version -5.5.2

please suggest proper configuration file and help me to use v3.
