# Add subslot templates to the interface card template

In the Inventory Template form in the Network Inventory Workspace Lists view, you can add subslots to the interface card template that you created. You perform this procedure any time that you add a new card model to an existing equipment inventory template.

## Procedure

If the interface card supports SFP \(Small Form Pluggable\), the card has slots. To create this relationship, you can use the same procedures that you used to add slots to in the equipment inventory template. To learn more, see [Add slots to the equipment inventory template](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/telecom-network-inventory/telecommunications-network-inventory/adding-slot-equipment-model.md).

The following example shows an inventory card template where subslots were added.

In the interface card template, in the **Related Templates** tab, click **New** to create a subslot inventory template.

After you submit the subslot inventory template, it appears on the **Related Templates** tab for the interface card.
