i am trying to migrate our switches to snmpv3. first, orion has no issue with the config below. works great

snmp-server engineID remote 10.2.16.11 udp-port 161 1000000000
snmp-server group Network01 v3 auth read godeep
snmp-server view godeep iso included
snmp-server view godeep mib-2 included
snmp-server view godeep interfaces included
snmp-server view godeep chassis included

snmp-server user GXXXX Network01 v3 auth md5 <password> priv aes 256 <password>

 

but NetMRI will not authenticat or connect.  i have followed the instructions in the 7.4.5 manual, the devices can ping each other. no ACL is in the way. and snmpv2 still works on netmri.

any help would be awsome.

good news, we figured out what was up. we were pointing the config at solarwinds only. once we put in a local enginID we could hit netmri. but encryption for aes 256 or 192 does not work for snmpv3. i found a KB #3925 from 2016! that states

Problem Summary

Network Automation unsuccessfully attempts to authenticate devices configured with SNMP v3 and AES-256 bit or SNMP v3 and AES-192 bit encryption

 

Customer Environment

SNMP v3 network devices using AES-256 bit or AES-192 bit encryption

 

Versions

All Network Automation(NetMRI) versions

 

Cause

Network Automation only authenticates SNMP v3 devices which are configured with AES-128 bit encryption.

 

Resolution

When SNMP v3 network devices are configured with AES-256 bit encryption or AES-192 bit encryption, reconfigure these devices with AES-128 bit encryption.
