A subnetwork represents a topological subpart within a domain network and tier where features have traversability to the same subnetwork controllers. Subnetworks are used to drive analytics and visualize your network through rendering, labeling, and map generation.
Some of the properties for subnetworks are assigned when the domain network they reside in is created. These properties are for all subnetworks in the domain network. Additional properties for subnetworks can be set at the tier level using the Set Subnetwork Definition geoprocessing tool. The domain network and tier properties can be reviewed using the Network Properties.
For more details on the components set for a subnetwork at the tier level, see Subnetwork definition.
To set subnetwork definitions, the following requirements must be met:
Set the subnetwork definition for a tier
To set the subnetwork definition for the specified tier, complete the following steps:
- On the Analysis tab, in the Geoprocessing group, click Tools to open the Geoprocessing pane.
- In the Geoprocessing pane, search for and select Set Subnetwork Definition.
- For the Input Utility Network parameter, choose a utility network.
- For the Domain Network parameter, choose the domain network.
- For the Tier Name parameter, choose a tier.
- Optionally, choose an option for Support Disjoint Subnetwork.
Option for disjoint subnetworks is only available for tiers within domain networks that have a partitioned tier definition.
- Checked—The tier can support disjoint subnetworks.
- Unchecked (Default)—The tier does not support disjoint subnetworks.
- For the Valid Devices parameter, check all the device asset types that can participate in these subnetworks.
If the topology definition for tiers in the input domain network is hierarchical, this option presents a subset of the valid devices defined for the parent tier (highest parent tier).
- For the Valid Subnetwork Controllers parameter, specify the device asset types that can be set up as subnetwork controllers for the subnetworks in the tier.
The asset group and asset types listed for valid subnetwork controllers must have the system network category of subnetwork controller assigned.
- For the Valid Lines parameter, check all the line asset types that can participate in these subnetworks.
If the topology definition for tiers in the input domain network is hierarchical, this option presents a subset of the valid lines defined for the parent tier (highest parent tier).
- Among the valid lines, specify the lines whose geometry will be aggregated to create the subnet lines—Aggregated Lines For SubnetLine Feature Class.
- If you want the system to automatically create subnetwork system diagrams for each subnetwork of that tier, specify the diagram templates you want those network diagrams to be based on—Subnetwork Diagram Templates.
- In the Subnetwork Trace Configuration section, optionally set any desired conditions. These will be used to auto-populate settings in the Trace geoprocessing tool for subnetwork traces. They are also used by the Update Subnetwork tool to define which features define the subnetwork and are updated. Finally, the Export Subnetwork tool uses these settings to determine what information to export.

The subnetwork properties are defined for the tier. To view the subnetwork properties, open the layer properties and view the network properties tab. To establish subnetworks within the tier, review the Create a subnetwork topic.
