Calculating Ring Impacts

Ring impact analysis identifies ring topologies that are affected by an impact analysis event. Ring calculations evaluate the directly impacted connectivity associated with the event.

Each calculation uses one calculation method. When you calculate rings again by using a different method, the new calculation replaces the results of the earlier calculation.

Ring impact analysis returns only rings associated with directly impacted connectivity. It does not return every ring that matches the selected calculation method.

Use Calculate Rings to identify rings affected by an event.

Consider the following conditions before you start calculating ring impacts:

You must be assigned the Analyst role or Administrator role.
For a planned or simulated event, select a specific resource before calculating rings. Ring calculation is not supported when the resource selection is All.

To calculate ring impacts:

In the Events tab, open the required event.
Click View Impact Summary.
For a planned or simulated event, select a specific resource by name or ID.

Note:
Do not select All.
Click Calculate Rings.
In the Select Ring Calculation Method dialog box, select a calculation method.
Click Calculate Rings.
The calculation starts. While the calculation is in progress, the action is unavailable and indicates that ring calculation is in progress.

Note:

Calculate Rings remains visible when the resource selection is All. If you select it while All is selected, the calculation does not start and existing results do not change. The following message appears:

Calculate Rings is not supported for All resources. Please select specific resource to calculate rings.

Selecting a Ring Calculation Method

Select the calculation method that provides the most appropriate scope for identifying affected rings.

Table 12-2 Ring Calculation Methods

Method	Description
Ring Name	Uses the Ring Name associated with the directly impacted connectivity. Use this method when discovered network data identifies the ring in which the connectivity participates.
Network	Uses the network associated with the directly impacted connectivity as the search context.
Specification	Searches for rings by using the specification of the directly impacted connectivity.
Rate Code	Searches for rings by using the rate code of the directly impacted connectivity.
Technology	Searches for rings by using the technology of the directly impacted connectivity.
User Policy	Uses a policy configured by your administrator to select the appropriate calculation method.

Use the most specific method that is appropriate for the event. Ring Name and Network typically provide a narrower search scope than Specification, Rate Code, or Technology.

Note:

When you use the Specification, Rate Code, or Technology method, an edge that contains multiple connectivities is treated as having equivalent connectivity. The calculation evaluates one connectivity for the edge rather than evaluating all possible connectivity combinations.

The selected method defines where Service Impact Analysis searches for affected rings. The calculation returns only affected rings, not all rings that match the method criteria.

Viewing Ring Calculation Results

After ring calculation completes, the Rings value on the Impact Summary page displays the result. Select the information icon next to the value to view the calculation method that was used. You can select a ring calculation method using the Calculate Rings icon on the top-right corner of the summary pane.

Table 12-3 Ring Calculation Results

Rings Value or State	Meaning	Recommended Action
`--`	Rings have not been calculated, or the results were cleared when the impact was reanalyzed.	Click Calculate Rings and select a calculation method.
`Calculating`	The ring calculation request is in progress.	Wait for the calculation to complete. Do not start another calculation or reanalyze the impact.
`Positive count`	One or more affected rings were identified.	Select the information icon to view the calculation method. Click View Details to review the ring records.
`0`	No affected rings were identified.	Review the calculation method and select a broader or more appropriate method, if required.
`FAILED`	The ring calculation could not complete.	Review the displayed failure details, correct the condition, and calculate rings again by using an appropriate method.

For planned and simulated events, the All resource selection displays an aggregated Rings count for the parent event as follows:

A positive count indicates that one or more child resources have calculated affected rings.
A value of 0 indicates that ring calculation completed for every child resource and no affected rings were found.
A value of -- indicates that ring calculation has not completed for every child resource. For example, some child resources can have a result of 0 while other child resources have not been calculated.

Hover over the Rings Information icon to view the resources and method considered for ring calculations.

Note:

The ring calculations work only for ports and Device interfaces.

Recalculating Ring Impacts

Use Recalculate Rings to calculate rings by using a different method.

A new calculation replaces the existing ring impact results. It does not combine results from multiple calculation methods.

For planned and simulated events, select a specific resource before recalculating rings. Do not recalculate rings while the resource selection is All.

Reanalyzing an Impact After Calculating Rings

Reanalyzing an impact discards the current impact analysis and all calculated ring results.

If rings have been calculated, selecting Reanalyze Impact displays the following confirmation message:

Are you sure you want to reanalyze? Doing so requires recalculation of the rings.

Click Reanalyze to continue. The analysis restarts, the Rings value returns to --, and you must calculate rings again after the impact analysis completes.

Working with Impact Analysis Details

You use the Impact Analysis Details page to understand more about the generated impact analysis. The Impact Analysis Details page shows the following details of the analysis:
