also query APs for information about the network’s available IP address type (IPv4 or IPv6), roaming partners,
and supported authentication methods, and receive that information in Information Elements from the AP.
Generic Advertisement Service (GAS) Queries
An Organization Identifier (OI) is a unique identifier assigned to a service provider when it registers with the
IEEE registration authority. Starting with ArubaOS 6.3, an AP can include its service provider OI in beacons and
probe responses to clients. If a client recognizes an AP’s OI, it will attempt to associate to that AP using the
security credentials corresponding to that service provider.
If the client does not recognize the AP’s OI, that client can send a Generic Advertisement Service (GAS) query to
the AP to request more information more about the network before associating.
ANQP Information Elements
ANQP Information Elements (IEs) are additional data that can be sent from the AP to the client to identify the
AP’s network and service provider. If a client requests this information via a GAS query, the hotspot AP then
sends the ANQP Capability list in the GAS Initial Response frame indicating support for the following IEs:
l Venue Name: defined using the wlan hotspot anqp-venue-name-profile command.
l Domain Name: defined using the wlan hotspot anqp-domain-name-profile command.
l Network Authentication Type: defined using the wlan hotspot anqp-nwk-auth-profile command.
l Roaming Consortium List: defined using the wlan hotspot anqp-roam-cons-profile command.
l NAI Realm: defined using the wlan hotspot anqp-nai-realm-profile command.
l Cellular Network Data: defined using the wlan hotspot anqp-3gpp-nwk-profile command.
l Connection Capability: defined using the wlan hotspot h2qp-conn-capability-profile command.
l Operator Class: defined using the wlan hotspot h2qp-op-cl-profile command.
l Operator Friendly Name: defined using the wlan hotspot h2qp-operator-friendly-name-profile
command.
l WAN Metrics: defined using the wlan hotspot h2qp-wan-metrics-profile.
Roaming Consortium OIs
Organization Identifiers (OIs) are assigned to service providers when they register with the IEEE registration
authority. You can specify the OI for the hotspot’s service provider in the ANQP Roaming Consortium profile
using the wlan hotspot anqp-roam-cons-profile command. This Hotspot profile also allows you to define and
send up to three additional roaming consortium OIs for the service provider’s top three roaming partners. To
send this additional data to clients, you must specify the number of roaming consortium elements a client can
query using the addtl-roam-cons-ois <1-3> parameter, then define those elements using the following
parameters:
l roam-cons-oi-1 and roam-cons-len 1
l roam-cons-oi-2 and roam-cons-len 2
l roam-cons-oi-3 and roam-cons-len 3
The configurable values for each additional OI include the Organization Identifier itself, the OI length, and the
venue group and venue type associated with those OIs.
Venue Types
The following list describes the different venue types that may be configured in a hotspot profile:
