Manual fabric topology parameters

Table 1. Basic parameters for manual topology fabric intent
Parameter	Description
Fabric Type	Indicates whether this is a Real or Digital Sandbox fabric. 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	Specifies the name that identifies this fabric.
Imported Topology From File	Specifies the name of a previously imported topology.
Description	Provides a description of the fabric intent. Optional.
Prefix Naming	Specifies 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	Specifies an already-created region. This identifies the region that contains the new fabric intent.
Domain	Optionally, provides a single domain name to be used as part of the fully qualified domain name (FQDN) for all of the nodes within the fabric. Multiple domain names separated by commas are not supported. When a domain name is provided, the Fabric Services System includes it within the system name parameter of the node configuration: `"system": { "name": { "host-name": <fss-sysname> "domain-name": <domain-name-from-fabric> } }` The Fabric Services System also updates its DHCP server with the specified domain name and host name. Like other aspects of node configuration, the inclusion of the domain name can be verified by right-clicking the node in the fabric design view and selecting Inspect Configuration. Note: This parameter is supported only for fabric intents created using a manual topology.
Labels	This area is disabled when creating the initial version of any fabric intent.
Deploy Trigger Percentage	Specifies 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	Specifies whether VLANS are permitted on inter-switch links (ISLs) Enabling this toggle allows the configuration of VLANs on 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 endpoints. 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.

Fabric Type

Indicates whether this is a Real or Digital Sandbox fabric.

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

Specifies the name that identifies this fabric.

Imported Topology From File

Specifies the name of a previously imported topology.

Description

Provides a description of the fabric intent.

Optional.

Prefix Naming

Specifies 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

Specifies an already-created region. This identifies the region that contains the new fabric intent.

Domain

Optionally, provides a single domain name to be used as part of the fully qualified domain name (FQDN) for all of the nodes within the fabric. Multiple domain names separated by commas are not supported.

When a domain name is provided, the Fabric Services System includes it within the system name parameter of the node configuration:

"system": {
    "name": {
        "host-name": <fss-sysname>
        "domain-name": <domain-name-from-fabric>
    }
}

The Fabric Services System also updates its DHCP server with the specified domain name and host name.

Like other aspects of node configuration, the inclusion of the domain name can be verified by right-clicking the node in the fabric design view and selecting Inspect Configuration.

Note: This parameter is supported only for fabric intents created using a manual topology.

Labels

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

Deploy Trigger Percentage

Specifies 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

Specifies whether VLANS are permitted on inter-switch links (ISLs)

Enabling this toggle allows the configuration of VLANs on 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 endpoints. 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.
