Step 5 Enable Predefined Probes

Three probes are required for the pre-flight checks to pass during onboarding. A set of optional probes is also available for better fabric visibility.

Required Probes:

  • Device Environmental Checks
  • Drain Traffic Anomaly
  • Interface Flapping (Fabric Interfaces)

Optional Probes:

  • Interface Flapping (Specific Interfaces)
  • Hot/Cold Interface Counters (Specific Interfaces)
  • EVPN VXLAN Type-5 Route Validation

All of these probes are predefined in Data Center Director. Follow these steps to instantiate them in your blueprint.

  1. From your blueprint, navigate to Analytics > Probes.

  2. Click Create Probe and select Instantiate Predefined Probe from the drop-down list.
  3. In the Instantiate Predefined Probe dialog, select the probe you want to enable from the drop-down list.

Red arrows highlight probe type dropdown and create button.
  4. Configure the probe to suit your anomaly detection requirements. The default settings work for most deployments.
  5. Click Create.
    Note:

    You must retain the default probe names during creation. Otherwise, Data Center Assurance won’t pick them up when it runs the pre-flight checks.

    The probe is instantiated and appears in the probes table. Repeat these steps for each required probe and any optional probes you want to enable.
