Fabrics

Fabrics

Fabrics are on-premises network regions that consist of a group of switches and other networking devices that provide connectivity for your applications and endpoints. You can split fabrics into different availability zones, such as pods, that are analyzed and managed by Nexus Dashboard Insights.

Types of on-premises fabrics

  • Online fabrics: Multiple Nexus switches running ACI or NX-OS that can be represented by a controller such as APIC or NDFC and connected to Nexus Dashboard Insights to continuously stream telemetry. Types of online fabrics include:

    • ACI: Multiple Nexus switches with Cisco ACI and represented by a Cisco APIC.

    • NDFC: Multiple Nexus switches with Cisco NX-OS and represented by a Cisco NDFC.

    • NX-OS: A group of Cisco Nexus 9000 switches running NX-OS without a controller.

  • Snapshot fabrics: Controller-based fabrics, that are referenced by a snapshot, for use in one-time analysis or demonstrations. They may or may not be connected to Nexus Dashboard Insights over the network.

To learn about how to prepare fabrics for onboarding, see Add fabrics.

Once your fabric is onboarded and fully prepared, Nexus Dashboard Insights will start the fabric analysis to collect data from your fabric and display the fabric information in the Fabrics page. See Fabric Details. From there, you can view your fabric’s general information, inventory, L2 and L3 connectivity, endpoints, anomalies and advisories and more! To learn more see Fabric Details.

Prerequisites

Guidelines and Limitations

When you onboard a Cisco ACI fabric using the Ready to Add option in Nexus Dashboard Insights, you cannot specify the Login Domain in Nexus Dashboard Insights. You can specify the Login Domain in Nexus Dashboard’s Admin Console.

Add fabrics

You can add a fabric to Nexus Dashboard Insights using the following methods:

  • Online fabrics

    • Enable the fabric that has already been added to Nexus Dashboard. Fabrics added to the Nexus Dashboard are not enabled in the services by default, so you will need to explicitly enable them directly from Nexus Dashboard Insights.

    • Add a fabric directly to Nexus Dashboard Insights.

  • Snapshot fabrics

    • Add a snapshot fabric.

Fabric Details

In Nexus Dashboard Insights, Global View provides bird’s eye view of your global network infrastructure for all your fabrics. The Fabrics page provides the details for an individual fabric.

For multi-cluster deployments see section Multi-Cluster Connectivity in Journey and Global View.

Fabric Details in Global View

After you add the first fabric, Global View gives you a bird’s eye view of your global network infrastructure for all your fabrics, their locations, and the key health metrics.

Navigate to Overview> Global View.

The map visually shows the physical location and total number of your fabrics in each continent, and their names. Click a fabric to jump directly to the details for that fabric, or scroll down to the Fabrics area to navigate to your fabric. You can also use the the zoom control icons in the page to change your view of the map.

See an at-a-glance summary for each individual fabric in the Fabrics area. It includes their anomaly and advisory health levels, fabric-external traffic with total data transferred, and connectivity data for endpoints and Layer 3 neighbors. To learn about fabrics in Global View, see Journey and Global View.

Individual Fabric Details

In the Fabrics page, you can dive into the details for an individual fabric, switch, or interface, with a comprehensive dashboard, simple topology, per-device summaries and more. You can also manage anomalies and advisories at a fabric level.

  1. Navigate to Manage > Fabrics.
