Microsoft.SystemCenter.NetworkDevice.Interface.InboundErrorThresholdMonitor (UnitMonitor)

Performance health state monitor that will show error state and alert when inbound error packets exceed the defined threshold

Summary

Inbound Errors Threshold Monitor

Causes

Below are the details of the Object Identifier (OID) that is queried via an SNMP GET

Object

OID

Description

ifInErrors

.1.3.6.1.2.1.2.2.1.14

For packet-oriented interfaces, the number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol. For character-oriented or fixed-length interfaces, the number of inbound transmission units that contained errors preventing them from being deliverable to a higher-layer protocol.

Resolutions

Below are some basic troubleshooting steps

  1. Check the cabling to the device.

  2. Perform any vendor specific hardware tests on the device to determine if the device's hardware is functioning properly

  3. Raise the threshold on the monitor. This will allow for better "tuning" of the application to your environment. Take care no to raise the threshold too much as this could allow important events to go unnoticed.
