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

The vehicle-ground fast link handover network is a single-hop Layer 2 Mesh network composed of the AC, trackside APs, and vehicle-mounted APs.
- The AC is deployed on the ground network to manage and control trackside APs.
- Trackside APs are Fit APs deployed along the track. They function as MPPs and communicate with the AC in wired mode at Layer 2.
- Vehicle-mounted APs: are Fat APs deployed in the front and rear of a train. They function as MPs to set up Mesh links with trackside APs.
Each vehicle-mounted AP can only use one radio for vehicle-ground communications at one time.
On a vehicle-ground fast link handover network, the AP9131DN (Fit AP) or AP9132DN (Fit AP) is usually used as the trackside AP and the AP9131DN (Fat AP) or AP9132DN (Fat AP) as the vehicle-mounted AP. If other AP models are used as the vehicle-mounted and trackside APs, they must comply with the same 802.11 standards, for example, both 802.11ac APs or 802.11n APs.
Only the AP9132DN and AP8182DN support antenna combination and split modes.
