Create a new OT subnet mapping record

Create a new OT subnet mapping to associate with an equipment model entity.

Before you begin

Role required: sn_ot_amazing_write or sn_ot_amazing_admin

Note: When creating new OT subnet mapping records, by default the new records are inactive. To automatically map records when the OT device mapping flow triggers, OT subnet mapping records must be active.

Procedure

1. Navigate to All > Equipment Model - ISA > Equipment Model Entities.

   Alternatively, you can navigate to All > Industrial Workspace Admin > OT Subnet Mapping. Then select New in the OT Subnet Mappings table. If you create an OT subnet mapping record using this method, continue from step 4.

2. Select the site or equipment model entity you want to create a new mapping for.

   Note: Subnet mapping also supports Discovery created configuration items (CIs) for ISA equipment models.

3. Select the Mapped OT Subnets related list, then select New.

4. On the form, fill in the fields.

5. Field	Description
   Name	Zone or VLAN name for the subnet.
   Site	From the Lookup, select the ISA site from the list of available sites if not already populated.
   Type	Select the subnet type from these options:- IP Range - a subset of IP addresses in a subnet - IP Network - the entire subnet, in CIDR notation - Discovered Subnet - a discovered subnet in your OT network
   Discovered subnet	Reference to the OT Discovered Subnet [sn_ot_discovered_subnet] table. This field only appears if you select Discovered Subnet for the Type field.
   Starting IP Address	Starting IP for the IP Range This field is visible when Type is IP Range.
   Ending IP address	Ending IP for the IP Range This field is visible when Type is IP Range.
   Source name	Name of the source, such as NetDB or Firewall.
   Firewall Name	Name of the firewall managing the zone if applicable.
   Description	Description for the subnet mapping.
   Active	Select Active to include the subnet in automated mapping when the OT Subnet Mapping scheduled flow executes.
   Equipment model entity	From the Lookup, select the equipment model entity from the list of available entities if not already populated.
   Subnet	Enter the subnet address (CIDR format). This field is visible when Type is IP Network.
   Location	Add a location to the subnet record to automatically add or update the location in the mapped OT devices.Note: The location is mapped based on the sn_otsm.subnet_mapping.location_auto_update system property. For more information about system properties used for OT subnet mapping, see System properties used by the OT subnet mapping feature.
   Interface name	Name for the firewall interface if applicable.
   VLAN ID	Specify the VLAN ID if applicable.

   1. Select Submit.
