Onboard Devices

 

Follow these steps to onboard brownfield devices from the Contrail Command user interface (UI):

  1. Click Fabrics.

    The Fabrics page is displayed.

  2. Click Create.

    You are prompted to select a provisioning option.

  3. Click Existing Fabric to import existing (brownfield) devices by discovery.
    Figure 1: Select Provisioning Option
    Select Provisioning Option
  4. Click Provision.

    The Create Fabric page is displayed.

  5. Enter the following information:

    Table 1: Provision Existing Fabric

    Field

    Action

    Name

    Enter a name for the fabric.

    Username

    Enter a username for the device.

    Password

    Enter a password for the device.

    Overlay ASN (iBGP)

    Enter autonomous system (AS) number in the range of 1-65,535.

    If you enable 4 Byte ASN in Global Config, you can enter 4-byte AS number in the range of 1-4,294,967,295.

    Node profiles

    Add node profiles.

    You can add more than one node profile.

    All preloaded node profiles are added to the fabric by default. You can remove a node profile by clicking X on the node profile.

    Management subnets

    Enter the following information:

    CIDR—Enter CIDR network address.

    Gateway—Enter gateway address.

    Note: You enter the CIDR address range in the Management subnets field to search for devices. Any device that has a previously configured management IP on the subnet is discovered.

    Underlay ASNs (eBGP)

    Enter autonomous system (AS) number in the range of 1-65,535.

    If you enable 4 Byte ASN in Global Config, you can enter 4-byte AS number in the range of 1-4,294,967,295.

    • Enter minimum value in ASN From field.

    • Enter maximum value in ASN To field.

    Fabric subnets (CIDR)

    Enter fabric CIDR address.

    Note: Fabric subnets are used to assign IP addresses to interfaces that connect to leaf or spine devices.

    Loopback subnets (CIDR)

    Enter loopback address.

    Note: Loopback subnets are used to auto-assign loopback IP addresses to the fabric devices.

    PNF Servicechain subnets (CIDR)

    Enter PNF device CIDR address.

    Note: Starting in Contrail Networking Release 5.1, enter the subnet for allocating IP addresses in the PNF Servicechain subnets field to establish EBGP session between PNF device and SPINE switch.

  6. Click Next.

    The Discovered devices page is displayed.

    The Device discovery progress bar on the Discovered devices page displays the progress of the device discovery job.

    Figure 2: Device Discovery Progress Bar
    Device Discovery Progress Bar

    The list of devices discovered are listed in the Discovered devices page.

  7. Select the device(s) you want to add to the fabric and then click Add.

    The device is added to the fabric.

  8. Click Next to assign roles.

    The Assign to devices page is displayed.

  9. Click the Assign icon at the end of the row to assign roles.

    The Assign role to devices pop-up is displayed.

  10. Assign physical roles and routing bridging roles.

    For Spine Devices:

    • Select spine from the Physical Role list.

    • Select CRB-Gateway from the Routing Bridging Roles list.

    For Leaf Devices:

    • Select leaf from the Physical Role list.

    • Select CRB-Access from the Routing Bridging Roles list.

    For PNF Devices:

    • Select PNF from the Physical Role list.

    • Select CRB-Access and PNF-Servicechain from the Routing Bridging Roles list.

    Note

    The number of PNF instances you can create depends on the subnet mask of the pnf-servicechain-subnet that you provided during fabric onboarding. You can create multiple /29 subnets from the pnf-servicechain-subnet.

    For example, if a /24 subnet is provided for the pnf-servicechain-subnet, then, you can create 25= 32(29-24=5) subnets out of it. Each PNF uses a pair of /29 subnets. Thus, for a /24 subnet, you can have a maximum of 16 PNFs.

    For VNF Devices:

    • Select VNF from the Physical Role list.

    • Select CRB-Access from the Routing Bridging Roles list.

      Note

      ERB-UCAST-Gateway routing bridging role is also supported.

    Note

    When you configure a QFX series device as a data center gateway, ensure that you assign DC-Gateway role to the spine device.

    To assign a DC-Gateway role to a spine device,

    • Select spine from the Physical Role list.

    • Select DC-Gateway from the Routing Bridging Role list.

  11. Click Assign to confirm selection and then click Autoconfigure to initiate the auto-configuration job.

    The Autoconfigure page is displayed.

    The Autoconfigure progress bar on the Discovered devices page displays the progress of the auto-configuration job. Once the auto-configuration job is completed, click Next.

  12. From the Assign Telemetry Profiles page, click Finish to exit the Create Fabric wizard.

    The onboarding job is now complete.
