Verify DC Assurance Setup

The Apstra Edge device forwards event and anomaly information from the data center to Juniper Data Center Assurance. To ensure that DC Assurance receives insights and anomaly data from the data center, relevant configurations must be made in Apstra and on the Edge. You can verify these configurations by using:

  • Juniper Data Center Assurance Setup Validation Tool—verifies the data center fabric connectivity and the device configurations.

  • Pre-flight Checks—verify the Edge version and blueprint configurations on Apstra.

Juniper Data Center Assurance Setup Validation Tool

After the Apstra Edge device has been installed and set up, you can run the Juniper Data Center Assurance Setup Validation Tool. This tool performs a series of tests to verify that you have configured the various devices and services of your DC fabric correctly.

For information about the Juniper Data Center Assurance Setup Validation Tool, see Download and Run the Juniper Data Center Assurance Setup Validation Tool.

Pre-Flight Checks

The pre-flight checks feature verifies whether certain prerequisites and configuration requirements are met and provides actionable guidance on how to resolve potential issues. Executing these checks enables you to validate the environment, identify issues that might affect the performance of DC Assurance features, and resolve them.

The pre-flight checks feature helps you verify whether:

  • the blueprints are configured properly.

  • the probes that relay data center events and insights from Apstra Data Center Director to DC Assurance are enabled.

  • the Edge device is running the minimum software version required to support the latest DC Assurance features.

  • the Edge device is connected to the Apstra Flow Server.

  • the system times on the Apstra Flow Server and Juniper Data Center Assurance are in sync.

  • the stream receivers in Apstra are present and connected.

You can run pre-flight checks at the Edge level or for specific blueprints. If you run the pre-flight checks at the blueprint level, tests are run only on the selected blueprints. If you run the pre-flight checks at the Edge level, tests are run on the Edge as well as all the blueprints enabled on the selected device.

The pre-flight checks feature runs the following tests:

Table 1: Pre-flight tests
Component Pre-Flight Test Description

Apstra Edge

Edge Version Compatibility Check

Checks whether the onboarded Apstra Edge is running the minimum required version to support DC Assurance features.

Stream Receivers Creation Check

Checks whether the following stream receivers are present and connected:

  • Alerts

  • Perfmon

Apstra Flow Server Connection Check

Checks whether the Apstra Edge device and the Apstra Flow Server are connected.

Time Stamp Check between Apstra Flow Server and Juniper Data Center Assurance

Checks whether the timestamps on the Apstra Flow Server and Juniper Data Center Assurance are in sync.

Blueprint

Stream CPU and Memory Utilization Probe

Checks whether streaming is enabled for disk utilization, CPU utilization, and memory utilization data.

SLE Probes

Checks whether the following probes are enabled on Apstra:

  • Device Environmental Checks

  • Drain Traffic Anomaly

  • Interface Flapping (Fabric Interfaces)

Note:

You can enable any of the following optional probes to receive more insights from Apstra:

  • BGP Monitoring

  • ECMP Imbalance (Fabric Interfaces)

  • EVPN Host Flapping

  • EVPN VXLAN Type-3 Route Validation

  • EVPN VXLAN Type-5 Route Validation

  • Hot/Cold Interface Counters (Fabric Interfaces)

  • Hot/Cold Interface Counters (Specific Interfaces)

  • Interface Flapping (Specific Interfaces)

  • Optical Transceivers

  • VXLAN Flood List Validation

When a pre-flight check is run on a blueprint, the SLE Probes section in the Pre-flight Information page displays the list of optional probes that have not been enabled on Apstra.

Before you perform a pre-flight check, ensure that:

  • the Apstra Edge is registered.

  • the Apstra Edge is connected to the cloud and with the Apstra Controller.

  • any upgrade process on the Apstra Edge is complete.

To run a pre-flight check:

  1. Log in to Juniper Data Center Assurance.

  2. Navigate to the DC Edges page.

    The onboarded Edges are listed along with their connectivity status, the current version of software running on the Edge, available versions for upgrade, upgrade status, and results from the previous pre-flight check.

    Figure 1: Onboarded Apstra Edge Devices DC Edges page with a list of onboarded Apstra Edge devices along with their connectivity and version details.

  3. Select the Edge or the blueprint that you want to verify.

    Figure 2: Pre-flight Check Selection DC Edges page with an Edge device selected. The Run Pre-flight Checks button and the column with the Pre-flight Results are highlighted.

  4. Click Run Pre-flight Checks on the top right of the table.

    You can see the status of the check in the Pre-flight Results column.

  5. Click the link in the Pre-flight Results column to view the results. The Pre-flight Information page opens.

    This page displays information about whether the device or blueprint passed or failed the tests. Select the failed test to view more information and guidance on how to resolve the issue.

    Note:

    The SLE Probes section in the Pre-flight Information page for a blueprint also displays a list of optional probes that you can enable to receive more detailed insights from Apstra.

    Figure 3: Pre-flight Information Pre-flight Information page with the descriptions of the tests, status of the tests, and recommended action on failure.
    Note:

    You can perform pre-flight checks on an Apstra Edge device or on blueprints at any time after the device has been onboarded.
