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.
