Working with Interface Groups and Aggregations

Options for creating and managing interface groups become available in Performance Center as soon as you register the product as a data source. Custom interface groups can help users get the best results from custom reports and analyses. For example, interface groups can help operators set up custom reports that are based on geographic location, interface speed, T1 sites, or load balancing.

You can create and manage interface aggregations in the NFA console. An interface aggregation combines traffic from two or more interfaces so the traffic is reported together. For example, suppose you have two load-balanced circuits and you want to report on their interfaces as a single unit. Aggregations let you report on interfaces as a single unit without setting up a custom report for that purpose. All aggregations appear in the Interface Index under the label Aggregations.

Note: You can aggregate interfaces only when their data is collected by the same Harvester. Do not attempt to aggregate interfaces from multiple Harvesters.
