You are a senior network consultant speaking to a client's IT director in a private briefing. Speak in British English with a confident, authoritative, conversational tone. Measured pace, clear diction. No filler words. Occasional natural pauses for emphasis: Welcome to this technical briefing on integrating Allied Telesis TQ-Series access points with Purple WiFi. I'm going to walk you through the full deployment picture, from guest captive portal redirection through to multi-tenant PPSK isolation. By the end of this, you'll have a clear implementation roadmap. [medium pause] Let's start with context. Allied Telesis produces the TQ-Series, including the TQ5403 and TQ6702 GEN2 Wi-Fi 6 access points. These are enterprise-grade APs running AlliedWare Plus firmware, and they're deployed widely across hospitality, retail, and public sector environments. Purple is a hardware-agnostic cloud overlay platform operating across 80,000 venues and handling 440 million logins in 2024. The integration between these two platforms is clean, standards-based, and production-ready. [medium pause] Now, the first thing most IT teams need to configure is guest captive portal redirection. The Allied Telesis AP supports three captive portal modes: click-through, RADIUS authentication, and external page redirect. For Purple integration, you'll use the External Page Redirect mode. Here's how that works in practice. You log into the AP's device GUI, navigate to Wireless, select the relevant VAP, go to Advanced Settings, then the Security tab. Set Captive Portal to External Page Redirect. In the External Page URL field, you enter the Purple splash page URL provided in your Purple dashboard. That's the URL your guests will hit when they first connect. [short pause] Now, the AP intercepts the first HTTP or HTTPS packet from each new client and redirects that traffic to your Purple splash page. The guest authenticates through Purple, and Purple's RADIUS server sends an Access-Accept back to the AP. The AP then grants network access. [medium pause] For the RADIUS configuration, Purple provides you with a RADIUS server IP address, a shared secret, and the authentication port, which is UDP 1812. Accounting runs on UDP 1813. You configure these under Network Services, then RADIUS in the AP GUI. The NAS identifier should be set to the AP's management IP or a descriptive hostname. Purple's RADIUS as a Service handles the authentication backend, so you don't need to run your own RADIUS infrastructure. [short pause] One thing to get right is the Walled Garden. Before a guest authenticates, the AP blocks all traffic except to whitelisted destinations. You need to add Purple's platform domains to the walled garden so the splash page loads correctly. At minimum, whitelist the Purple splash page domain, any CDN endpoints Purple uses for assets, and any social login providers you've enabled, such as Google or Facebook. You configure this in the same VAP Advanced Settings panel under Walled Garden. [medium pause] Let's move on to Staff WiFi using 802.1X. This is where you configure WPA Enterprise on a separate VAP. In the AP GUI, select WPA Enterprise from the Security dropdown, then point the RADIUS Authentication Group at your external RADIUS server, which in this case is Purple's SecurePass service or your own Microsoft Entra ID or Okta-backed RADIUS. Staff devices authenticate using EAP-PEAP with MSCHAPv2, or EAP-TLS with certificates for higher security environments. The AP acts as the 802.1X authenticator, forwarding credentials to the RADIUS server and enforcing the response. [short pause] For dynamic VLAN assignment on the staff network, you enable Dynamic VLAN in the VAP's Advanced Security settings. When the RADIUS server returns an Access-Accept, it includes three standard attributes: Tunnel-Type set to VLAN, Tunnel-Medium-Type set to IEEE 802, and Tunnel-Private-Group-Id set to the VLAN ID. The AP reads these attributes and places the authenticated device onto the correct VLAN automatically. This is the mechanism defined in RFC 3580 and it works consistently across Allied Telesis hardware. [medium pause] Now let's talk about the most interesting capability for multi-tenant deployments: Allied Telesis PPSK, or Private Pre-Shared Key. This is sometimes called iPSK on other platforms. The concept is straightforward. You have a single SSID, but each tenant or user group gets a unique passphrase. When a device connects, the AP sends that passphrase to the RADIUS server as the password field in a RADIUS Access-Request. The RADIUS server matches the passphrase to a user record, and returns an Access-Accept with a Tunnel-Private-Group-Id attribute specifying the VLAN for that tenant. [short pause] So in a mixed-use building, Tenant A in the retail unit connects with their passphrase and lands on VLAN 100. The restaurant on the ground floor uses a different passphrase and lands on VLAN 300. The building's guest WiFi uses a third passphrase and lands on VLAN 400 where Purple's captive portal is active. All of this runs on one SSID. No SSID proliferation. Clean, scalable, and easy to manage. [medium pause] On the Purple side, you configure the PPSK user records in the Purple dashboard or via the RADIUS as a Service interface. Each tenant gets a unique passphrase mapped to a VLAN ID. Purple's RADIUS server handles the matching and returns the correct Tunnel-Private-Group-Id. When you need to revoke a tenant's access, you delete or disable their PPSK record in Purple. The AP enforces the change at the next authentication attempt. [medium pause] Let me give you two real-world scenarios where this matters. First, a 250-room conference hotel. The hotel runs three networks: guest WiFi with Purple splash page and social login, staff WiFi on 802.1X tied to Active Directory via Microsoft Entra ID, and a conference delegate network for events. The Allied Telesis TQ6702 GEN2 APs handle all three on separate VAPs with separate VLANs. Purple manages the guest splash page, collects first-party data for the hotel's CRM, and provides analytics on peak usage periods. The hotel's IT team manages the staff network through Purple's SecurePass without maintaining a separate RADIUS server on-site. [short pause] Second scenario: a retail park with 12 independent tenants. The landlord wants to offer WiFi as a service to each tenant without giving them access to each other's traffic. They deploy Allied Telesis APs throughout the site with a single SSID. Each tenant receives a unique PPSK. Purple's RADIUS server maps each PPSK to a dedicated VLAN. The landlord can onboard a new tenant in under ten minutes by creating a new PPSK record in Purple and handing the passphrase to the tenant. No AP reconfiguration required. [medium pause] Now, a few pitfalls to avoid. The most common issue we see is misconfigured walled gardens. If you forget to whitelist a Purple CDN endpoint, the splash page will partially load or fail on certain devices. Test with a fresh device that has no cached DNS before going live. Second, RADIUS shared secret mismatches. The secret configured on the AP must exactly match the secret in Purple's RADIUS server configuration. A single character difference causes silent authentication failures. Use a password manager to generate and store the secret. Third, Dynamic VLAN not enabling. On Allied Telesis APs, Dynamic VLAN is disabled by default even when WPA Enterprise is active. You must explicitly enable it in the VAP Advanced Security settings. We see this missed regularly. Fourth, PPSK and MAC authentication conflict. If you have MAC authentication enabled on the same VAP as PPSK, the authentication order matters. Check the AP documentation for your firmware version to confirm which method takes precedence. [medium pause] Quick-fire questions I get from IT teams. Can I use Purple's RADIUS server for both guest captive portal and staff 802.1X on the same deployment? Yes. Purple's RADIUS as a Service supports both authentication flows. You configure separate RADIUS groups or policies in Purple for each use case. Do Allied Telesis APs support WPA3 with captive portal? The TQ6702 GEN2 running firmware 5.5.4-2.3 or later supports WPA3 CCMP cipher. However, captive portal with external redirect typically runs on an open or WPA2 Personal SSID. Staff 802.1X can use WPA3 Enterprise. What happens if the Purple RADIUS server is unreachable? The AP will deny new authentication attempts. Existing sessions continue until they time out. You should configure a secondary RADIUS server in the AP's RADIUS group for redundancy. Purple's platform maintains 99.999% uptime, but defence in depth is good practice. [medium pause] To summarise. Allied Telesis TQ-Series APs integrate with Purple through three primary mechanisms: external captive portal redirect for guest WiFi, WPA Enterprise with RADIUS for staff 802.1X, and PPSK with dynamic VLAN for multi-tenant isolation. The RADIUS attributes you need are Tunnel-Type VLAN, Tunnel-Medium-Type IEEE 802, and Tunnel-Private-Group-Id carrying the VLAN ID. Purple provides the RADIUS as a Service backend, the splash page platform, and the analytics layer. [short pause] Your next steps: pull the Purple RADIUS credentials from your dashboard, configure the external page redirect on your guest VAP, add the walled garden entries, enable Dynamic VLAN on your staff VAP, and run a test authentication for each network segment before going live. If you're deploying PPSK for multi-tenant, plan your VLAN numbering scheme before you start, because changing VLAN IDs after tenants are live requires coordination. [medium pause] That's the briefing. For the full step-by-step configuration reference, the Mermaid architecture diagram, and the RADIUS attribute table, see the written guide. Thank you for your time.

Resumen ejecutivo

Implementar puntos de acceso de la serie TQ de Allied Telesis con Purple proporciona una arquitectura de red escalable, segura y altamente configurable. Este manual de integración detalla la configuración de la redirección externa de Captive Portal para Guest WiFi, la autenticación 802.1X para Staff WiFi y el mapeo de claves precompartidas privadas (PPSK) para el aislamiento de redes multiinquilino. Al combinar el hardware de Allied Telesis con Purple RADIUS como servicio, centraliza la gestión de identidades y elimina la necesidad de servidores RADIUS locales. Esta guía cubre los atributos RADIUS específicos requeridos para el direccionamiento dinámico de VLAN, la configuración de Walled Garden para una entrega fluida de la página de inicio (splash page) y las mejores prácticas para escalar redes basadas en identidad en entornos de hotelería, comercio minorista y sector público.

Análisis técnico detallado

Los puntos de acceso de Allied Telesis, como el TQ6702 GEN2 y el TQ5403, ejecutan el firmware AlliedWare Plus. Admiten funciones empresariales robustas que incluyen WPA3, Passpoint (Hotspot 2.0) e integración completa con RADIUS. Cuando se integra con Purple, el punto de acceso actúa como el servidor de acceso a la red (NAS) y el autenticador 802.1X, mientras que Purple opera como el servidor RADIUS alojado en la nube y el proveedor de Captive Portal.

Redirección de Captive Portal de invitados

Para Guest WiFi, el punto de acceso intercepta el tráfico de clientes no autenticados y redirecciona las solicitudes HTTP/HTTPS a la página de inicio de Purple. Esto requiere configurar el modo de Captive Portal en External Page Redirect.

Cuando un invitado se conecta, el AP hace referencia a su configuración de Walled Garden. El Walled Garden debe incluir en la lista de permitidos los dominios de Purple, los endpoints de CDN y cualquier proveedor de inicio de sesión social configurado (como Google Workspace o Microsoft Entra ID). Una vez que el invitado completa el flujo de autenticación en la página de inicio, el servidor RADIUS de Purple envía un mensaje RADIUS Access-Accept (puerto UDP 1812) al punto de acceso, que luego otorga acceso completo a la red.

Direccionamiento dinámico de VLAN a través de RADIUS

La asignación dinámica de VLAN es fundamental para la segmentación de la red. Al configurar Staff WiFi mediante WPA Enterprise, el punto de acceso reenvía las credenciales EAP al servicio RADIUS SecurePass de Purple.

Tras una autenticación exitosa, el servidor RADIUS de Purple devuelve un paquete Access-Accept que contiene tres atributos RADIUS estándar de la IETF definidos en RFC 3580:

  1. Tunnel-Type (Atributo 64): Establecido en VLAN (13).
  2. Tunnel-Medium-Type (Atributo 65): Establecido en IEEE-802 (6).
  3. Tunnel-Private-Group-Id (Atributo 81): Establecido en el ID de VLAN asignado (por ejemplo, 20).

El AP de Allied Telesis lee estos atributos y coloca dinámicamente el dispositivo cliente en la VLAN especificada. Nota: La VLAN dinámica debe habilitarse explícitamente en la configuración de seguridad avanzada de VAP dentro de la GUI de Allied Telesis.

Aislamiento multiinquilino con PPSK

La clave precompartida privada (PPSK) le permite utilizar un único SSID mientras asigna diferentes contraseñas a diferentes usuarios o inquilinos. Esto es altamente efectivo en unidades de viviendas múltiples (MDU), espacios de coworking y parques comerciales.

Cuando un dispositivo se asocia mediante una PPSK específica, el punto de acceso envía la contraseña al servidor RADIUS de Purple. Purple mapea la contraseña a un perfil de inquilino específico y devuelve el atributo Tunnel-Private-Group-Id. Esto dirige los dispositivos del inquilino a su VLAN dedicada, lo que garantiza el aislamiento de Capa 2 sin transmitir múltiples SSIDs.

Guía de implementación

Siga estos pasos para configurar los puntos de acceso de Allied Telesis para la integración con Purple.

Paso 1: Configurar el perfil del servidor RADIUS

  1. Inicie sesión en la GUI del dispositivo AP de Allied Telesis.
  2. Vaya a Network Services > RADIUS.
  3. Agregue un nuevo servidor RADIUS externo utilizando la dirección IP proporcionada en su panel de control de Purple.
  4. Establezca el puerto de autenticación en 1812 y el puerto de contabilidad (accounting) en 1813.
  5. Ingrese el Secreto compartido exacto proporcionado por Purple.
  6. Configure el Identificador NAS para que coincida con la IP de administración o el nombre de host del AP.

Paso 2: Configurar Guest WiFi (Captive Portal)

  1. Vaya a Wireless > Radio1 (o Radio2).
  2. Haga clic en Edit para el VAP de destino (por ejemplo, VAP0).
  3. Establezca el nombre del SSID (por ejemplo, "Guest WiFi").
  4. Vaya a la pestaña Advanced Settings > Security.
  5. Establezca Captive Portal en External Page Redirect.
  6. Ingrese la URL de la página de inicio de Purple en el campo External Page URL.
  7. En Walled Garden, agregue los dominios de Purple requeridos y las IP de inicio de sesión social.

Paso 3: Configurar Staff WiFi (802.1X y VLAN dinámica)

  1. Edite un VAP independiente para Staff WiFi.
  2. Establezca la seguridad en WPA Enterprise.
  3. Seleccione el perfil del servidor RADIUS de Purple en el menú desplegable RADIUS Authentication Group.
  4. Vaya a Advanced Settings > Security.
  5. Habilite Dynamic VLAN.
  6. Asegúrese de que los switches de red de respaldo estén configurados para enlazar (trunk) las VLAN asignadas dinámicamente a los puertos del AP.

Paso 4: Configurar PPSK para multiinquilino

  1. Edite el VAP destinado al uso multiinquilino.
  2. Habilite PPSK (a menudo se configura junto con la autenticación MAC o configuraciones específicas de WPA, según la versión del firmware).
  3. Asegúrese de que el perfil del servidor RADIUS esté seleccionado.
  4. En el panel de control de Purple, cree los registros de usuario de PPSK, mapeando cada contraseña al ID de VLAN correcto.

Mejores prácticas

  • Mantenimiento de Walled Garden: Regularmente revise y actualice las entradas de Walled Garden. Los proveedores de inicio de sesión social cambian frecuentemente sus rangos de IP y dominios de CDN.
  • Redundancia: Configure siempre las direcciones IP del servidor RADIUS de Purple principal y secundario en el grupo RADIUS del AP para garantizar una alta disponibilidad.
  • Actualizaciones de firmware: Mantenga actualizado el firmware de AlliedWare Plus. El soporte para WPA3 CCMP y las funciones avanzadas de PPSK requieren la versión 5.5.4-2.3 o posterior.
  • Troncalización de VLAN: Verifique que los puertos del switch conectados a los puntos de acceso estén configurados como troncales 802.1Q y permitan todas las VLAN que el servidor RADIUS pueda asignar dinámicamente.

Resolución de problemas y mitigación de riesgos

  • Fallos de autenticación silenciosos: Si los dispositivos no pueden conectarse a la red 802.1X o PPSK, verifique el secreto compartido de RADIUS. Una discrepancia hace que el AP descarte silenciosamente los paquetes Access-Reject.
  • Error al cargar la página de bienvenida: Si el redireccionamiento del Captive Portal entra en un bucle o no carga los recursos, es probable que falten dominios requeridos en el Walled Garden. Inspeccione la consola de desarrollador del navegador para identificar las solicitudes bloqueadas.
  • Clientes asignados a la VLAN incorrecta: Si el direccionamiento dinámico de VLAN falla, verifique que la VLAN dinámica esté habilitada explícitamente en el VAP. Utilice la captura de paquetes para verificar que Purple esté devolviendo el atributo Tunnel-Private-Group-Id.

ROI e impacto empresarial

La integración de Allied Telesis con Purple transforma la conectividad inalámbrica básica en una plataforma inteligente impulsada por datos.

Para los equipos de TI, centralizar la autenticación a través de Purple RADIUS como servicio elimina la sobrecarga de administrar servidores RADIUS locales e integraciones de Active Directory en el extremo. El uso de PPSK reduce la sobrecarga de SSID, lo que mejora el rendimiento de RF y simplifica la incorporación de inquilinos.

Para las operaciones del recinto, el Captive Portal recopila datos de primera mano verificados, lo que impulsa el crecimiento del CRM y permite el marketing dirigido. Con más de 29 mil millones de puntos de datos recopilados en la plataforma Purple, los recintos obtienen información útil sobre el comportamiento de los visitantes, los tiempos de permanencia y la utilización del espacio, respaldando directamente los objetivos comerciales.

Definiciones clave

PPSK (Private Pre-Shared Key)

A security mechanism where multiple unique passphrases can be used on a single SSID, with each passphrase mapped to specific network policies or VLANs.

Used in multi-tenant environments to provide secure, isolated network access without broadcasting multiple SSIDs.

Tunnel-Private-Group-Id

RADIUS Attribute 81, defined in RFC 2868, used to specify the VLAN ID that a user or device should be assigned to upon successful authentication.

Essential for dynamic VLAN steering in both 802.1X and PPSK deployments.

Walled Garden

A restricted network environment that allows unauthenticated users access to a specific whitelist of IP addresses or domains.

Required for captive portals to allow devices to load the splash page and authenticate via social login providers before gaining full internet access.

RADIUS as a Service

A cloud-hosted RADIUS infrastructure managed by a third party (like Purple), eliminating the need for on-premises authentication servers.

Simplifies 802.1X deployments for distributed venues by centralising identity management in the cloud.

Captive Portal

A web page that users are forced to view and interact with before access is granted to a public WiFi network.

Used to capture first-party data, enforce terms of service, and display venue branding.

VAP (Virtual Access Point)

A logical entity within a physical access point that broadcasts its own SSID and maintains its own security and policy configurations.

Allows a single Allied Telesis AP to simultaneously provide Guest WiFi, Staff WiFi, and IoT connectivity.

EAP-PEAP

Protected Extensible Authentication Protocol, a secure method for transmitting authentication credentials inside an encrypted TLS tunnel.

The most common authentication protocol used for Staff WiFi (802.1X) when verifying usernames and passwords against a directory.

Access-Accept

A standard RADIUS packet sent by the server to the authenticator (AP) indicating that authentication was successful.

Often includes additional attributes, such as VLAN assignments or bandwidth limits, to enforce network policy.

Ejemplos resueltos

A 250-room hotel needs to deploy a secure staff network and a branded guest network. The IT team wants to manage staff access via Microsoft Entra ID without deploying a local RADIUS server, while guests must accept terms and conditions via a captive portal.

Deploy Allied Telesis TQ6702 GEN2 APs. Configure VAP0 as an open network with Captive Portal set to 'External Page Redirect', pointing to the Purple splash page URL. Configure VAP1 with WPA Enterprise, pointing the RADIUS Authentication Group to Purple's SecurePass RADIUS servers. Integrate Purple SecurePass with Microsoft Entra ID in the cloud. Enable Dynamic VLAN on VAP1 so staff are automatically steered to the internal VLAN upon successful EAP authentication.

Comentario del examinador: This approach uses Purple as a cloud identity broker. It eliminates on-premises RADIUS infrastructure while maintaining strict Layer 2 isolation between guest and staff traffic using standards-based 802.1X and dynamic VLAN assignment.

A retail park landlord wants to provide WiFi to 12 independent retail units using a single hardware deployment. Each unit requires its own secure, isolated network segment.

Configure a single SSID (e.g., 'Retail-Park-Secure') on the Allied Telesis APs. Enable PPSK (Private Pre-Shared Key) and point authentication to the Purple RADIUS server. In the Purple dashboard, generate a unique passphrase for each retail unit and map it to a specific VLAN ID (e.g., Unit 1 = VLAN 101, Unit 2 = VLAN 102). When a device connects, the AP sends the passphrase to Purple, which returns the Tunnel-Private-Group-Id attribute, steering the device to the correct tenant VLAN.

Comentario del examinador: PPSK prevents SSID proliferation, which degrades RF performance. It provides the user experience of a simple WPA2/WPA3 personal password while delivering the enterprise security and segmentation of 802.1X.

Preguntas de práctica

Q1. A venue reports that Android devices can connect to the Guest WiFi and see the splash page, but Apple iOS devices show a blank white screen. What is the most likely configuration issue?

Sugerencia: Consider how different operating systems detect captive portals and what domains they need to reach.

Ver respuesta modelo

The Walled Garden is likely missing the specific domains Apple uses for captive portal detection (e.g., captive.apple.com). If the AP blocks these domains before authentication, the iOS Captive Network Assistant cannot trigger the mini-browser correctly.

Q2. You have configured WPA Enterprise on the AP and pointed it to Purple's RADIUS server. The RADIUS logs show successful authentication (Access-Accept), but the client device does not receive an IP address on the expected VLAN. What are the two most likely causes?

Sugerencia: Check both the AP configuration and the physical switch port configuration.

Ver respuesta modelo
  1. 'Dynamic VLAN' is not enabled in the VAP Advanced Security settings on the Allied Telesis AP. 2. The switch port connecting the AP is not configured as an 802.1Q trunk, or the target VLAN is not allowed on the trunk, preventing DHCP traffic from reaching the client.

Q3. A retail park wants to deploy PPSK for 50 tenants. They ask if they should create 50 separate VAPs or use a single VAP. What is your recommendation and why?

Sugerencia: Consider the impact of management frames on wireless airtime.

Ver respuesta modelo

Recommend using a single VAP with PPSK. Broadcasting 50 separate SSIDs generates excessive beacon frames and management overhead, severely degrading RF performance and available airtime. A single SSID with PPSK provides the same Layer 2 isolation via dynamic VLAN assignment without the RF penalty.
