hen you set up the snmp user command does that user have to match a local user account on the router/swtich? (Or a radius/tacacs+ account). If so does that mean the auth password has to match the user account? I am having trouble connecting to our NMS when I start using the authnoPriv or authPriv contexts. I know I have the crypto IOS so that is not the issue. I can make connection to our NMS using noAuthnoPriv, but I would like more security. We do use tacacs+ for our user account login and the it goes back to local login if the ACS Server is down. Does this mean I have to use tacacs+ for my SNMPv3 authentication? Are there any good docs on that out there? Any help on this would be great! Thank you!
