Discovery agent could not discover devices.

Issue/Introduction

Problem:

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:

Logs entry:

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?

Environment:

UIM 7.X or 8.X

Discovery_agent 7.X or 8.X

SNMP device using SNMPV3

 

Cause:

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.
