A single word	`cat`	Topics that contain the word "cat". You will also find its grammatical variations, such as "cats".
A phrase. You can specify that the search results contain a specific phrase.	`"cat food"` (quotation marks)	Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase.

Interface Form: Conclusions Tab

[This is the Context-Sensitive Help topic for the Interface form, Conclusions tab.]

The Interface Form provides details about the selected network interface.

All relevant conclusions are shown in the table on this tab. The most severe Status in the current group of conclusions becomes the overall Interface status. Some Interface conclusions propagate to other object types: See Also

Description

Outstanding Status Conclusions

The dynamically generated list of summary statuses of the interface that contributed to the current overall status of the selected interface. Status is set by the Causal Engine.

Each Conclusion listed is still outstanding and applies to the current overall Status.

This view is useful for obtaining a quick summary of the Status and problem description for the current node’s interfaces that led up to the interface’s most current Status.

The Status value is correlated based on the most critical Conclusions.

Double-click the row representing a Conclusion. The Conclusion form displays all details about the selected Conclusion.

The following table describes the possible Conclusions that might appear for an interface object.

A Y in the Incident? column indicates that the Conclusion results in an incident.

AggregatorDown	Link AggregationProtocols used on Switches to configure multiple Interfaces (Aggregation Member Interfaces) to function as if they were one (an Aggregator Interface). When two Aggregator Interfaces establish a connection, that connection is an Aggregator Layer 2 Connection.

Some vendors refer to this as Multi-Chassis Link Aggregation, SLAG, MLAG, or MC-LAG.: The Operational State of the Aggregator Interface is Down (if monitored), or all of the Aggregation Member Interfaces are Down.

Major Status Conclusions (NNM iSPI Performance for Metrics)

Conclusion	Description	Status	Incident?
InterfaceFCSLANErrorRateHigh	Local Area Network. Indicates a Frame Check Sequence (FCS) error rate on the interface has gone above a threshold setting. The error rate is based on the number of frames that were received with a bad checksum (CRCCyclic Redundancy Check value). Possible causes include collisions at half-duplex, a duplex mismatch, bad hardware (NICNetwork Interface Controller, cable, or port), or a connected device generating frames with bad FCS.	Major	Y
InterfaceFCSWLANErrorRateHigh	Wireless Local Area Network. A Frame Check Sequence (FCS) error rate on the interface has gone above a threshold setting. The error rate is based on the number of frames that were received with a bad checksum (CRCCyclic Redundancy Check value). Possible causes include collisions at half-duplex, a duplex mismatch, bad hardware (NICNetwork Interface Controller, cable, or port), or a connected device generating frames with bad FCS.	Major	Y

Possible causes include that the number of packet buffers allocated to the interface is exhausted or has reached its maximum threshold.	Major	Y
