Manual fabric topology parameters

Table 1. Basic parameters for manual topology fabric intent

Parameter

Description
Fabric Type

Select Real. This creates a fabric intent intended for deployment to real-world hardware.

The Digital Sandbox option is used to create a virtual fabric to test and validating prospective designs. This option is described in Digital Sandbox.
Fabric Intent Name

Enter the name that identifies this fabric.
Imported Topology From File Use this drop-down list to select the name of a previously imported topology.
Description

Optionally, add information to describe the fabric intent.
Prefix Naming

Enter a string to be added at the beginning of the name of every node in the fabric intent. The rest of the node name is automatically generated.

For example, enter "A01" here to assign nodes names such as "A01-leaf-1" and "A01-spine-1".

The Prefix Naming string must be unique to each fabric.
Region

In the drop-down list, click an already-created region from the list. This identifies the region that contains the new fabric intent.

To create or edit a region now, click the regions icon ( ) to navigate to the Regions page. This exits the fabric intent creation procedure. You must begin fabric intent creation again after creating the new region.
Labels

This area is disabled when creating the initial version of any fabric intent.
Deploy Trigger Percentage

The minimum percentage of nodes within the fabric intent that must be physically installed before the system allows you to deploy the intent to hardware.

For all real fabrics, this value is fixed at 0%.

For a full explanation of the impact of this setting, see The Deployment Trigger Percentage setting.
VLANs on ISL Enabling this toggle allows the configuration of VLANs on inter-switch links (ISLs). In the Fabric Services System, this capability is unique to fabric intents using a manual topology; conventionally configured fabric intents do not currently support VLANs on ISLs.

Enabling this toggle displays a VLAN ID field. Use this field to specify the VLAN tag that should be created on the ISL endoints. Only a single VLAN is currently supported.

If required you can change the value for this VLAN tag by creating a new version of the fabric intent, selecting a new value here, and deploying the new version.

This setting is disabled by default.
