As SNMPv2 gets phased out due to security issues, we have a Network Flow Analysis feature being worked on to make the SNMP Watchdog service work with SNMPv3.
Component : Network Flow Analysis
We have a Feature: F119822 opened to get the SNMP Watchdog service code updated to work with SNMPv3 as a lot of companies are disabling v2 due to weak security.
We will post more information as soon as we have an ETA for this on this tech doc.
