Issue/Introduction

Bits in/out or any metric containing ifInOctets/ifOutOctets stops displaying data at 20Mbs. 

Environment

NetOps Performance Management 3.7

Cause

The interface was discovered with a speed of 0 bps. This would cause the interface to use 32 bit counters as 0 bps is < 20 Mbps The High Speed Interface Vendor Certification will drop the ifInOctets/ifOutOctets if they exceed the maximum value that should be able to pass in a single poll.

Resolution

Set the proper speed for the interface, If the Speed is > 20Mbps, the interface will then use 64 bit counters and will no longer include the calculation that drops ifINOctets or ifOutOctets.
