# Configuring a VLAN

> **Applies to:** SBC 3.1, 3.3

After you create a virtual port, you must create a new VLAN.

### To configure a VLAN

1. Select **IP Interfaces** from the navigation panel

2. Click the **Virtual Ports** tab.

* Select a Virtual Port

3. Create a VLAN that uses this virtual port

* Click **Create new Host VLAN**

4. Configure the new VLAN

**Important Note**

Vlans can be configured on the SBC in these cases:

* Baremetal installation
* VMware installation with Passthrough or SR-IOV network interfaces
* VMware installation with a network interface using vlan ID 4095

Vlans should **not** be configured on the SBC in this case:

* VMware installation with network interfaces using vlans from 1 to 4094 In this case, all interfaces on the SBC should be configured as untagged. Vlans are configured in the VMware port Groups.

Please check here: [How to add VMware Network Interfaces](https://github.com/telcobridges-main/tmedia-wiki/tree/main/tmedia/operations/vmware-adding-network-interfaces/README.md)

If VLANs must be configured, follow these steps:

* Enter a name for the VLAN
* If the port is to be used untagged, make sure **Untagged** is checked.
* If the port is to be used with a 802.1Q tag, uncheck **Untagged** and enter a VLAN ID.
* Click **Create**

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://prosbcdocs.telcobridges.com/tmedia-documentation/configuration/configuring-a-vlan.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
