Hotspot 2.0

Introduction to Hotspot 2.0

The Hotspot 2.0 feature enables IEEE 802.11 devices to interwork with external networks. The interworking service aids network discovery and selection, enabling information transfer from external networks. It provides information to the stations about the networks before association.

Interworking not only helps users within the home, enterprise, and public access domains, but also assists manufacturers and operators to provide common components and services for IEEE 802.11 customers. These services are configured on a per-WLAN basis on the Cisco Wireless Controller (controller).

Hotspot 2.0, also known as HS2 and Wi-Fi Certified Passpoint, is based on the IEEE 802.11u and Wi-Fi Alliance Hotspot 2.0 standards. It seeks to provide better bandwidth and services-on-demand to end users. The Hotspot 2.0 feature allows mobile devices to join a Wi-Fi network automatically, including during roaming, when the devices enter the Hotspot 2.0 area.

The Hotspot 2.0 feature has four distinct parts:

Hotspot 2.0 Beacon Advertisement: Allows a mobile device to discover Hotspot 2.0-compatible and 802.11u-compatible WLANs.
Access Network Query Protocol (ANQP) Queries: Sends queries about the networks from IEEE 802.11 devices, such as network type (private or public); connectivity type (local network, internet connection, and so on), or the network providers supported by a given network.
Online Sign-up: Allows a mobile device to obtain credentials to authenticate itself with the Hotspot 2.0 or WLAN.
Authentication and Session Management: Provides authentication (802.1x) and management of the STA session (session expiration, extension, and so on).

In order to mark a WLAN as Hotspot 2.0-compatible, the 802.11u-mandated information element and the Hotspot 2.0 information element is added to the basic service set (BSS) beacon advertised by the corresponding AP, and in WLAN probe responses.

Note

The Hotspot 2.0 feature supports only local mode or FlexConnect mode (central switching and central authentication).

FlexConnect local switching is only supported when the Open Roaming configuration template is set up using the wireless hotspot anqp-server server-name type open-roaming command. If the configuration diverges from this template, FlexConnect local switching will not be supported.

The following figure shows a standard deployment of the Hotspot 2.0 network architecture:

Figure 1. Hotspot 2.0 Deployment Topology

Open Roaming

From Cisco IOS XE Amsterdam Release 17.2.1, the controller supports open roaming configuration, which enables mobile users to automatically and seamlessly roam across Wi-Fi and cellular networks.

The new configuration template of the open roaming ANQP server simplifies the task of setting up a Hotspot 2.0 ANQP server. When you configure open roaming, fixed ANQP parameters are automatically populated.

You can configure different identity types by defining roaming organizational identifiers. The organizational unique identifier (OUI) is a three-octet number that identifies the type of organizations available in a given roaming consortium. The OUI list determines the type of identities allowed to roam into the network. The default configuration allows all the identities on the access network. However, access networks can customize the Roaming Consortium Organization Identifier (RCOI) they advertise.

You can configure three types of policies for access networks:

Allow all: Accepts users from any identity provider (IDP), with any privacy policy.
Real ID: Accepts users from any IDP, but only with a privacy policy that shares real identity (anonymous not accepted).
Custom: Accepts users of select identity types and privacy policies associated with the identity types; basically all the other RCOIs.

Users can select the following privacy modes:

Anonymous
Share real identity

The list of currently defined organizational identifiers and their aliases are given in the following table.

Configuring Hotspot 2.0

Configuring an Access Network Query Protocol Server

The Access Network Query Protocol Server (ANQP) is a query and response protocol that defines the services offered by an AP, usually at a Wi-Fi Hotspot 2.0.

Note

When configuring roaming-oi in the ANQP server, ensure that you set the beacon keyword for at least one roaming-oi, as mandated by the 802.11u standard.

Procedure

Command or Action Purpose

Step 1

configure terminal

Example:

Device# configure terminal

Enters global configuration mode.

Step 2

wireless hotspot anqp-server server-name

Example:

Device(config)# wireless hotspot anqp-server my_server

Configures a Hotspot 2.0 ANQP server.

Step 3

description description

Example:

Device(config-wireless-anqp-server)# description "My Hotspot 2.0"

Example:

Device(config-wireless-anqp-server)# 3gpp-info us mcc

Configures a 802.11u Third Generation Partnership Project (3GPP) cellular network.

The mobile-country-code should be a 3-digit decimal number. The mobile-network-code should be a 2-digit or 3-digit decimal number.

Step 5

anqp fragmentation-threshold threshold-value

Example:

Device(config-wireless-anqp-server)# anqp fragmentation-threshold 100

Configures the ANQP reply fragmentation threshold, in bytes.

The ANQP protocol can be customized by setting the fragmentation threshold, after which the ANQP reply is split into multiple messages.

Note

We recommend that you use the default values for the deployment.

Step 6

anqp-domain-id domain-id

Example:

Device(config-wireless-anqp-server)# anqp-domain-id 100

Configures the Hotspot 2.0 ANQP domain identifier.

Step 7

authentication-type { dns-redirect | http-https-redirect | online-enrollment | terms-and-conditions}

Example:

Device(config-wireless-anqp-server)# authentication-type online-enrollment

Configures the 802.11u network authentication type. Depending on the authentication type, a URL is needed for HTTP and HTTPS.

Step 8

connection-capability ip-protocol port-number { closed| open| unknown}

Example:

Device(config-wireless-anqp-server)# connection-capability 12 40 open

Configures the Hotspot 2.0 protocol and port capabilities.

Note

Hotspot 2.0 specifications require that you predefine some open ports and protocols. Ensure that you meet these requirements in order to comply with the Hotspot 2.0 specifications. See the connection-capability command in the Cisco Catalyst 9800 Series Wireless Controller Command Reference document for a list of open ports and protocols.

Step 9

To see the full list of language codes, go to: http://www.loc.gov/standards/iso639-2/php/code_list.php.

Note

You can configure only one operator per language.

Step 15

osu-ssid SSID

Example:

Device(config-wireless-anqp-server)# osu-ssid test

Configures the SSID that wireless clients will use for OSU.

The SSID length can be up to 32 characters.

Step 16

roaming-oi OI-value [ beacon]

Example:

Device(config-wireless-anqp-server)# roaming-oi 24 beacon

Configures the 802.11u roaming organization identifier.

If the beacon keyword is specified, the roaming OUI is advertised in the AP WLAN beacon or probe response. Otherwise, it will only be returned while performing the roaming OUI ANQP query.

Note

The hex string of a roaming OUI should contain only lowercase letters.

Step 17

venue venue-name language-code

Example:

Device(config-wireless-anqp-server)# venue bank eng

Configures the 802.11u venue information.

The venue-name should not exceed 220 characters and the language-code should only be 2 or 3 lowercase letters (a-z) in length.

Configuring Open Roaming (CLI)

The new configuration template of the open roaming ANQP server simplifies the task of setting up a Hotspot 2.0 ANQP server. When you configure open roaming using this template, default ANQP parameters are automatically populated. The default values defined in the template always override any user-defined configuration values. For example, these are the default values enforced with the type open-roaming template:

nai-realm open.openroaming.org
eap-method eap-tls
eap-method eap-ttls
inner-auth-non-eap mschap-v2
inner-auth-non-eap pap
eap-method eap-aka

You can add more fields to the existing template, but ensure that they do not overlap with the existing default values. Also, if you change any of these default values, you will need to re-configure every time you enter in anqp type open-roaming config.
