Licensing Requirements and Limitations for WLAN Traffic Optimization

Involved Network Elements

APs mentioned in this document are Huawei AP products. You are advised to use Huawei APs to connect to the AC.
You can run the display ap-type all command to check the default AP types supported by the device.
When central APs and RUs are used, ensure that their versions are the same. For example, if the central AP version is V200R007C10, the RU version must be V200R007C10.

Licensing Requirements

When the device is used as a WLAN AC, the number of online APs supported by the device is controlled by licenses. The device supports a maximum of 16 online APs. To increase the number of online APs supported by the device, apply for and purchase a license from the agent.

AP resource license-1AP for WLAN access controller
AP resource license-16AP for WLAN access controller
AP resource license-32AP for WLAN access controller
AP resource license-64AP for WLAN access controller
AP resource license-128AP for WLAN access controller
AP resource license-512AP for WLAN access controller

For details about how to apply for a license, see Obtaining Licenses in the S1720, S5700, and S6700 Series Switches License Usage Guide.

Feature Support in V200R019C10

This feature is supported only by the following models: S5720-HI, S5730-HI, S5731-H, S5731S-H, S5732-H, S6720-HI, S6730S-H, and S6730-H.

Feature Limitations

Multicast-to-unicast conversion depends on the IGMP snooping function. Before configuring multicast-to-unicast conversion, enable IGMP snooping.
Multicast CAC depends on the function of converting multicast packets into unicast packets, but cannot be configured together with the adaptive function of converting multicast packets into unicast packets.
The multicast-to-unicast conversion on the air interface function is not available for the AirEngine 8760-X1-PRO, AirEngine 8760R-X1, AirEngine 8760R-X1E, AirEngine 6760-X1, AirEngine 6760-X1E, AirEngine 6760R-51, AirEngine 6760R-51E, AirEngine 5760-51, AirEngine 5760-22W, and AirEngine 5760-22WD.
