Gaps in interface reporting data in CA Performance Management (CAPM)

Products

• CA Performance Management - Usage and Administration

Issue/Introduction

Gaps appearing in interface reporting data even though the device is up and polling is uninterrupted.

Cause

If the device's Ethernet interface reports a value of 0 for ifHighSpeed (1.3.6.1.2.1.2.2.1.15), then CAPM will default to using ifSpeed (1.3.6.1.2.1.2.2.1.5) for the speed of the interface instead.

From the CAPM side, this is working as designed.

Environment

DX NetOps CAPM 20.2.x or later

Resolution

Workaround: Use a speed override on the interface(s) in question

Permanent Fix: Resolve the device configuration problem so that it reports a value for ifHighSpeed
