Questions about Dedicated Master and Preferred Master

=========================================================================

1) Dedicated Master
- Enable Dedicated Master

2) Preferred Master
-Disable WLAN service on Master AP
=>If the Unleashed Network contains 3 or more connected APs, the Master AP will not provide Wi-Fi service

=========================================================================

Q1. Are the operation methods the same when setting up 1) and 2)?

Q2. What are the differences between the two operation methods, if any?

Q3. After setting up 2), the Master AP Wi-Fi Server does not function with three or more APs.

Is the same thing if the existing Master dies and the Secondary becomes the Master?

Q4. Can the Preferred Master function be used with all APs, regardless of AP type?

Thank you.

Hi Hyshin,

Thank you for posting your query!

I understand that you would like to know the differences between Dedicated Master and Preferred Master modes in Ruckus Unleashed.

1. Dedicated Master

The AP functions only as a controller and does not provide Wi-Fi service.

If it goes down, a standby master can take over — this requires manual configuration.

It supports advanced management features such as VLANs and AP approvals.

Supported only on specific models like R750, R770, and R850.

This mode effectively works as a dedicated controller, increasing overall management capacity.

2. Preferred Master

A normal AP that has priority to become the Master if the current one fails.

When it’s not acting as Master, it continues to serve Wi-Fi clients.

If the Master fails, the system automatically promotes the Preferred Master (and Secondary, if configured).

Easy to configure via the web UI, and does not require manual intervention.

The Preferred Master (Wi-Fi 6) setup can support up to 50 APs and 1,024 clients.

>The Dedicated Master offers higher management capacity and is ideal for networks prioritizing stability and control.

>The Preferred Master provides automatic and flexible redundancy, making it simpler to maintain with minimal manual effort.

Your documentation says preferred master supports 8 Switches, 128 APs, 2048 clients. The limits you state are for gateway mode?

And maybe be a bit clearer that the Dedicated Master supports controller/AP VLANs and L3 (incl.tunneling), since WLAN/DPSK VLANs are also available with a preferred master.

Hi @ms264556,

In Bridge Mode : RUCKUS Unleashed supports a maximum 128 APs and 2,048 clients
per RUCKUS Unleashed network in bridge mode.

In Gateway mode : Ruckus Unleashed supports a maximum 25 APs and 512 concurrent clients due to the additional resource demands placed on the Master AP when in gateway mode.

With Dedicated Master : A RUCKUS Unleashed Dedicated Master network consists of two Dedicated Master APs (R750, R770, or R850) and a number of Unleashed member
APs (up to 150 total).

Yes. I was hoping to prod Mayank into correcting his answer.
