Fabric Discovery and ESXi Discovery by Using Contrail Command

Contrail Networking Release 1910 supports the Contrail vCenter Fabric Manager (CVFM) plug-in. After you deploy this plug-in, you must run the fabric discovery job and the ESXi discovery job from the Contrail Command UI.

These topics provide instructions to run the discovery job.

Fabric Discovery

Follow these steps to discover fabric devices.

Navigate to the Infrastructure>Fabrics page in Contrail Command.
Click Create.
You are prompted to select a provisioning option.
Click Existing Fabric to import existing (brownfield) devices by discovery.
Note:
VMware-Contrail Networking Fabric integration supports greenfield device discovery and brownfield device discovery.

Figure 1: Select Provisioning Option
Click Provision.
The Create Fabric page is displayed.

Enter the fabric provisioning information as listed in Table 1.

Table 1: Provision Existing Fabric
Field		Action
Name		Enter a name for the fabric.
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.
VLAN-ID Fabric Wide Significance		Select the check box to enable enterprise style of configuration for the CRB-Access role on QFX devices. De-select the check box to enable service provider style of configuration for the CRB-Access role. The check box is selected by default since enterprise style is the default setting. You can modify the enterprise style setting to service provider style once configured. However, you cannot modify the service provider style to enterprise style. Note: Contrail Networking Release 1909 supports QFX10002-60C device running Junos OS Release 19.1R2 and later. QFX10002-60C device works only if enterprise style of configuration is enabled. To enable enterprise style of configuration, select the VLAN-ID Fabric Wide Significance check box when onboarding the QFX10002-60C device. For more information on enterprise style of configuration, see Configuring EVPN VXLAN Fabric with Multitenant Networking Services. For more information on supported hardware platforms and roles, see Contrail Networking Supported Hardware Platforms and Associated Roles And Node Profiles.
Username		Enter a username for the device.
Password		Enter a password for the device.
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.
Loopback subnets		Click Loopback subnets and enter loopback address in the CIDR field. Note: Loopback subnets are used to auto-assign loopback IP addresses to the fabric devices.
Underlay ASNs (eBGP)		Click Additional Configuration click +Add under Underlay ASNs (eBGP). Enter autonomous system (AS) number in the range of 1-65,535 in the CIDR field. 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)		Click +Add underFabric subnets (CIDR). Enter fabric CIDR address in the CIDR field. Note: Fabric subnets are used to assign IP addresses to interfaces that connect to leaf or spine devices.
Advanced interface filters		Click Advanced interface filters and select the Import configured interfaces check box.

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. The list of devices discovered is listed in the Discovered devices section.
Select the device you want to add to the fabric and then click Add.
The device is added to the fabric.
Click Next to assign roles.
The Assign to devices page is displayed.
Assign physical roles and routing bridging roles.
- To configure centrally-routed bridging (CRB):
  
  For Spine Devices:
  - Select spine from the Physical Role list.
  - Select CRB-Gateway from the Routing Bridging Role list.
  For Leaf Devices:
  - Select leaf from the Physical Role list.
  - Select CRB-Access from the Routing Bridging Role list.
- To configure edge-routed bridging (ERB):
  
  For Spine Devices:
  - Select spine from the Physical Role list.
  - Select CRB-MCAST-Gateway from the Routing Bridging Role list.
  For Leaf Devices:
  - Select leaf from the Physical Role list.
  - Select ERB-UCAST-Gateway from the Routing Bridging Role list.
Note:
Contrail Networking Release 19XX supports CRB-Access, CRB-Gateway, DC-Gateway, ERB-UCAST-Gateway, and CRB-MCAST-Gateway roles overlay roles. For more information, see Centrally-Routed Bridging Overlay Design and Implementation.

Assign a DC-Gateway Role to the spine device.
- Select spine from the Physical Role list.
- Select DC-Gateway from the Routing Bridging Role list.
For more information on supported hardware platforms, associated node profiles and roles, see Contrail Networking Supported Hardware Platforms and Associated Roles And Node Profiles.
Click Assign to confirm selection and then click Autoconfigure to initiate the auto-configuration job.
The Autoconfigure page is displayed.
After the autoconfigure process is completed, click Proceed to Servers Discovery.
You are redirected to the Infrastructure>Servers>Servers Discovery page.

ESXi Discovery

Follow these steps to discover ESXi servers by using the Contrail Command UI.

After you discover fabric devices, click Proceed to Servers Discovery. You are redirected to the Infrastructure>Servers>Servers Discovery page.

Click ESXi option button as shown in Figure 2.
Figure 2: Infrastructure > Servers > Servers Discovery

The vCenter Credentials section is displayed.
Enter the vCenter username in the Username field.
Enter the vCenter password in the Password field.
Note:
The vCenter IP Address and Data Center Name fields are populated with vCenter credentials that were entered before deploying the CVFM plug-in.
Click Next.
The Servers Discovery Page is displayed. The Device discovery progress bar on the Discovered devices page displays the progress of the device discovery job. The list of devices discovered is listed in the Discovered Servers section.
After the servers discovery job is completed, click Finish.
The Infrastructure>Servers page is displayed. The list of ESXi servers are displayed in the Servers page.
