Issue/Introduction

Symptoms:

• What does Default instrumentation mean for Card-Fault in Smarts IP Manager?
• Smarts IP Manager Device certification has Card-Fault = Default in instrumentation section.
• Smarts IP Manager Device Certification contains the following:

  INSTRUMENTATION:
  Card-Fault = Default

  
  
  

Environment

SMARTS - 10.1.x

SMARTS DM - 2.x

TCSA - 2.x

Resolution

• The Default card-fault instrumentation was introduced in Smarts IP Manager mainly because the OldCiscoChassis MIB was deprecated by Cisco.
• In previous versions of Smarts IP, every symptom for Card Down notifications required that the InstrumentedBy relationship was populated for that particular card.
• Therefore, if you had a Card without instrumentation objects, it could never fail.
• For example, if a Cisco device was certified to use the OldCiscoChassis MIB for Card-Fault, and then the device's IOS was upgraded so the OldCiscoChassis MIB was no longer supported, the Card Down notification would never be generated.
  • The Default card-fault instrumentation allows the Smarts IP codebook to decide if the Card om such a situation might be Down as follows: 
    • Card Down will be triggered based on the status of Network Adapters (Ports and Interfaces) that forms the "Realizes" relationship set for the Card.
    • This instrumentation object enables multiple NetworkAdapter failures to gravitate to the Card and generate a card down notification.
    • If one or more NetworkAdapters have a valid status, Card Down notification will not be generated.
  • The code analysis will prohibit a Card from being a candidate for the RCA if one or more NetworkAdapters have a valid status. These "valid" statuses are:
    • UP
    • DISABLED
    • OTHER
    • UNKNOWN
    • DORMANT
    • TESTING

  Any other status reported will be counted as if the card is "DOWN".
