Chapter 7 Impact Analysis

Impact Report Structure

Note Each fault which has been identified as potentially service affecting triggers a generation of impact analysis calculation event if it is reoccurring in the network.

This chapter describes the automatic impact analysis. For more information about proactive impact analysis, refer to the Cisco Active Network Abstraction NetworkVision User Guide.

Impact Report Structure

The impact report contains a list of pairs of endpoints when the service between them has been affected.

Each endpoint has the following details:

•Endpoint physical or logical location—An endpoint can be a physical entity (for example, a port) or a logical one (for example, a subinterface). The impact report contains the exact location of the entity. All the location identifiers start with the ID of the device which holds the endpoint. The other details in the location identifier are varied according to the endpoint type, for example VC, VP, IP interface.

•Business tag properties—Key, name, type (if attached to the entity).

Note For specific information about the report structure in MPLS networks, refer to the Cisco Active Network Abstraction MPLS User Guide.

Affected Severities

In automatic mode, the affected parties can be marked with one of the following severities:

•Potentially affected—The service might be affected but its actual state is not yet known.

•Real affected—The service is affected.

•Recovered—The service is recovered. This state relates only to entries that were marked previously as potentially affected. It indicates only the fact that there is an alternate route to the service, regardless of the service quality level.

•The initial impact report might mark the services as either potentially or real affected. As time progresses and more information is accumulated from the network, the system might issue additional reports to indicate which of the potentially affected parties are real or recovered.

•The indications for these states are available both through the API and in the GUI.

Note The reported impact severities vary between fault scenarios. For more information about fault scenarios in an MPLS network see the Cisco Active Network Abstraction MPLS User Guide.

Note There is no clear state for the affected services when the alarm is cleared.
