NFA 21.2.6 - 21.2.10 SNMP v3 Issues

Products

• CA Network Flow Analysis (NetQos / NFA)

Issue/Introduction

After upgrading to Network Flow Analysis 21.2.6 to 21.2.10, you may notice that some of your devices may have stopped SNMP polling. This would result in SNMP Refresh / SNMP Discovery failures from the NetOps Portal's Administration: NFA - "Manage Monitoring Page".

This issue would result in Proxies-Wrapper.log messages like this:

INFO   | jvm 1    | 2022/04/28 12:50:09 | java.lang.NullPointerException

Cause

This is due to the SNMP v3 Profile having Authentication but no Privacy protocol (AuthNoPriv) configured. 

Environment

Release : 21.2.6 - 21.2.10

Component : NFA

Resolution

1. If you can, please use a SNMP v3 Profile which uses Authentication and Privacy protocols.
2. If you can't change the profile, please download the patch for your version from the bottom of this doc and follow the readme instructions to get it installed. 

Additional Information
