Usage Guidelines

Usage Scenario

If a STA associates with an AP that has STA address learning enabled and obtains an IP address, the AP automatically reports the STA IP address to the AC to maintain the STA' IP address and MAC address binding entry

Prerequisites

Precautions

  • The device enabled with STA address learning can learn only a limited number of IPv6 addresses; therefore, you are advised to configure only one IPv6 prefix for the IPv6 gateway. If you configure too many IPv6 prefixes, the number of IPv6 addresses exceeds the upper limit, and extra IPv6 addresses cannot be learnt by the device. The IPv6 addresses not learnt by the device cannot be used for communications.

  • If a bridging device functions as a STA to connect to an AP enabled with STA address learning, the AP cannot learn IP addresses of users connected to the bridging device; therefore, the users cannot communicate with the network. In this situation, disable STA address learning.

  • Disabling STA address learning will lead to a Portal authentication failure.

Example

# Disable STA IPv4 address learning.

<HUAWEI> system-view
[HUAWEI] wlan 
[HUAWEI-wlan-view] vap-profile name vap1
[HUAWEI-wlan-vap-prof-vap1] learn-client-address ipv4 disable
