I have devices on my network that when using snmp V3 for the discovery_agent, the discovery fails.
In the logs I can see the following message:
Feb 29 15:33:11:906 INFO [PerIpDiscovery-118, discovery_agent] Could not discover remote engine ID for 10.10.3.2/161 : mostly likely not a SNMPv3 capable device
I have tested telnet to port 161 from the discovery_agent hub to the device and that works.
I have tested snmpget to the device from the same hub as the discovery_agent and that works.
Why is the discovery_agent failing?
UIM 7.X or 8.X
Discovery_agent 7.X or 8.X
SNMP device using SNMPV3
It was determined that the device was set to use AES 256 BIT or higher encryption.
Currently the discovery_agent only supports 128 BIT AES encryption.
