Parameter Description
Range Default
NOTE: This parameter only
defines the venue type
advertised in the IEs from
hotspot APs. To define the venue
type to be included in ANQP
responses, use the hotspot
anqp-venue-name-profile
<profile-name> command.
Usage Guidelines
Use this command to configure a hotspot profile. Hotspot 2.0 is a Wi-Fi Alliance specification based on the
802.11u protocol, which allows wireless clients to discover hotspots using management frames (such as
beacon, association request and association response), connect to networks, and roam between networks
without additional authentication.
The Hotspot 2.0 provides the following services:
l Network discovery and selection— Allows the clients to discover suitable and available networks by
advertising the access network type, roaming consortium, and venue information through the management
frames. For network discovery and selection, Generic Advertisement Service (GAS) and Access Network
Query Protocol (ANQP) are used.
l QOS Mapping— Provides a mapping between the network-layer QoS packet marking and over- the-air QoS
frame marking based on user priority.
When a hotspot is configured in a network:
l The clients search for available hotspots using the beacon management frame.
l When a hotspot is found, the client sends queries to obtain information about the type of network
authentication and IP address, and IP address availability using the Generic Advertisement Service (GAS)
action frames.
l Based on the response of the advertisement Server (response to the GAS Action Frames), the relevant
hotspot is selected and the client attempts to associate with it.
l Based on the authentication mode used for mobility clients, the client authenticates to access the network.
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. A W-IAP can include its service provider OI in beacons and probe responses to
clients. If a client recognizes the OI, it will attempt to associate to the W-IAP using the security credentials
corresponding to that service provider.
If the client does not recognize the 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 hotspot anqp-venue-name-profile command.
l Domain Name: Defined using the hotspot anqp-domain-name-profile command.
l Network Authentication Type: Define using the hotspot anqp-nwk-auth-profile command.
