# Add subslot templates to the interface card template

# Add subslot templates to the interface card template {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
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 {#adding-subslots-network-interface-template__section_gcc_fgw_htb}

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://servicenow-prod.fluidtopics.net/FFziTVnlXmLVAwXPMy221w "In the equipment inventory template that you created in the Network Inventory Workspace Lists view, use the Related Templates tab to create the associations for the slots. The following example shows how you add a related inventory template for an equipment model.").

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.

Next, add a network interface to an interface card template. To learn more, see [Add a network interface template to an interface card template](https://servicenow-prod.fluidtopics.net/aJvU0q0lVeFomE9PtI2xyw "If the interface card supports network interfaces directly to it, create an interface template relationship between the two interfaces in the Network Inventory Workspace Lists view.").
