# Multi-VLAN SSID

The most common use case for VLANs and Wi-Fi is likely the service provider, venue, enterprise where Wi-Fi traffic is not subject to address translation. This is the example that will be shown, however it is entirely possible to create multiple downstream VLANs with SSIDs as well. Simply replace the logic of upstream to downstream where desired.

In all cases the WAN port without VLAN id is using DHCP to obtain a management IP address. Each additional "upstream" role interface with an SSID associated have no IP configuration.

## 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://tip-1.gitbook.io/openwifi/device-feature-configuration-examples/basic-device-provisioning/multi-vlan-ssid.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.
