Usage Guidelines

Usage Scenario

When user terminals connect to a Hotspot2.0 network, Hotspot2.0 can transfer available IPv4 address types as ANQP parameters to the user terminals through APs. In this way, the user terminals can know the IP address types they can obtain after connecting to the network.

Example

# Set IPv4 addresses to available in hotspot2.0 profile hotspot.

<HUAWEI> system-view
[HUAWEI] wlan
[HUAWEI-wlan-view] hotspot2-profile name hotspot
[HUAWEI-wlan-hotspot2-prof-hotspot] ipv4-address-avail available
