CA Network Flow Analysis (NetQos / NFA)

Issue/Introduction

I'm trying to run an interface utilization report, but some devices don't come up on result report. Most devices interfaces show except for some devices that for some reason never show on report. 

Netflow is being received for device and we can see data graphs when looking interface individually.

 

Cause

Interface Speeds were not set on the interface

Environment

Release : 10.0

 

Resolution

In order for NFA to be able to calculate Utilization Percentages, NFA needs to be able to divide the current flow by the interface speed. If NFA does not know the interface speed, then it will be unable to calculate utilization as a percentage.

Found that the device was not reporting interface speeds via SNMP. Customer manually set SNMP speed, and the utilization percentage reports work.
