CA Performance Management - Usage and Administration DX NetOps

Issue/Introduction

A Trend View Chart in DX NetOps Performance Management (PM) Performance Center (PC) web UI Portal is showing 260Gbps inbound on a 10Gig circuit.

The Speed is set correctly on the device for the interface.

The interface is supported correctly by the "High Speed Interface" Vendor Certification.

Environment

All supported DX NetOps Performance Management releases

Cause

When enabling Detailed Poll Logging for the problem interface we see these excessively high values returned from the device from the ifHCInOctets.

We see here very high values, well over the 10GB the interface is configured for, coming back from the device during every 5 minute poll cycle.
