# Define your inventory numbering

# Define your inventory numbering {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Define the numbering for your virtual local area network (VLAN) or link aggregation
group (LAG) connections in the Telecommunications Network Inventory application. By
defining these inventory numbers, you can configure your network assets to activate a
network connection.

## Before you begin

Role required: sn_ni_core.inventory_admin, sn_ni_core.inventory_agent,
sn_ni_core.inventory_template_manager,
sn_ni_core.telco_inventory_catalog_manager

## About this task

The numbering that you define in this process creates VLAN and LAG number ranges,
allowing for the assignment of numbers from those ranges to network connections and
equipment ports. When you provision a network connection over an Ethernet network
interface to fulfill a customer order, you create a VLAN interface to support your
network topology. You must assign a VLAN number from 1 through 4096 for this
interface. You use this VLAN number to create an interface name so that you can
activate the interface on the network.

## Procedure

1. Navigate to WorkspacesNetwork Inventory Workspace.
2. Select the list icon (![List icon.]()), and then go to Inventory Number AllocationInventory Numbers.
3. Select New.
4. On the Details tab, fill in the general information for inventory numbering.
