Involved Network Elements

AP
  • 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 an X series card is used as a WLAN AC, the number of online APs supported by the X series card is controlled by licenses. The X series card supports a maximum of 16 online APs. To increase the number of online APs supported by the card, apply for and purchase a license from the agent.
  • AP resource license-16AP 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 S Series Switch License Use Guide.

Feature Limitations

  • The AD9431DN-24X central AP (including the mapping RUs), AD9430DN-24 central AP (including the mapping RUs), AD9430DN-12 central AP (including the mapping RUs), AP2010DN, AP2030DN, AP2050DN, AP2050DN-E, AP7030DE, AP9330DN, and AP6310SN-GN do not support the WDS function.

  • On a WDS or Mesh network, an 802.11ac AP cannot interoperate with non-802.11ac APs regardless of the radio types used by the AP. Only 802.11ac APs can interoperate with each other.
    NOTE:
    Among all WDS- or Mesh-capable APs, the AP1050DN-S, AP4050DN, AP4051DN, AP4151DN, AP8050DN, AP8150DN, AP5030DN, AP5130DN, AP8130DN, AP8030DN, AP8130DN-W, AP4030DN, AP4130DN, AP9131DN, AP9132DN, AP6050DN, AP6150DN, AP7050DE, AP7050DN-E, AP4030TN, AP4050DN-E, AP4050DN-HD, AP4051TN, AP6052DN, AP7052DN, AP7152DN, AP7052DE, AP8050TN-HD, AP8082DN, and AP8182DN are 802.11ac APs.
  • If radio 0 of the AP8130DN is configured to work on the 5 GHz frequency band and used for WDS or Mesh services, the software version of the AP connected to the AP8130DN must be V200R005C10 or a later version.

  • When planning a WDS network, pay attention to the following:
    • Only one root node exists on the WDS network.
    • A middle node sets up WDS links only with the leaf node and root node. Middle nodes do not set up WDS links between each other.
    • Each WDS link allows a maximum of three hops (a 3-hop WDS link includes a root node, a middle node, and a leaf node).
    • Each node on the WDS link supports a maximum of six subnodes.
  • This section provides only WDS configurations. After the WDS configuration is complete, APs can connect to an AC through wireless bridges. To use WLAN services, you still need to configure basic WLAN services. For details, see Example for Configuring WLAN Services on a Small-Scale Network.

  • When WDS is configured on dual-band APs, the root AP and leaf AP cannot use radio 0 or radio 1 simultaneously to establish a WDS link.

  • Ensure that the root, middle, and leaf nodes are bound to the same bridge profile; otherwise, WDS links cannot be set up or the existing WDS links get disconnected.

  • When configuring the WDS function, ensure that WDS nodes use the same channel.

  • The security profile used by WDS or Mesh links supports only the security policy WPA2+PSK+CCMP.

  • You are advised to configure different names for the profiles used to configure the WDS function than the profiles used to configure the WLAN service. These profiles are the WMM profile, radio profile, and security profile. This configuration facilitates maintenance on wireless bridges and WLAN service.

  • Avoid using radar channels to configure WDS links; otherwise, the following problems may occur:
    • Establishing WDS links on radar channels takes several minutes or several ten minutes longer than establishing WDS links on non-radar channels.
    • Radar signals cause disconnection of established WDS links.
  • A WDS bridge profile supports a maximum of 256 VLANs.

  • The WLAN Mesh function and WLAN WDS function are mutually exclusive. If the WLAN WDS function has been configured, the WLAN Mesh function cannot be configured.
  • During WDS network planning, if dual-band APs function as WDS nodes, AP radios bound to WDS bridge profiles cannot be configured to work in monitor mode; if single-band APs function as WDS nodes, AP radios cannot work in monitor mode.

  • If WIDS, spectrum analysis, background neighbor probing, or terminal location is enabled on a radio, the radio cannot be used to establish a WDS bridge or Mesh link.

  • Radio calibration does not take effect on radios enabled with WDS or Mesh functions.
  • In V200R005 and V200R006, if you set the CAPWAP heartbeat interval or the number of heartbeat packet transmissions to a small value using the capwap keep-alive interval interval-value or capwap keep-alive times times-value command, WDS or Mesh links may fail to be established. Therefore, you are advised to use the default values.

  • In V200R007 and later versions, if you set the CAPWAP heartbeat interval or the number of heartbeat packet transmissions to a small value using the capwap echo interval interval-value or capwap echo times times-value command, WDS or Mesh links may fail to be established. Therefore, you are advised to use the default values.

  • In V200R005 and V200R006, if WDS or Mesh is enabled simultaneously with dual-link backup, the AC sends CAPWAP heartbeat packets three times at an interval of 25 seconds by default. This may cause unstable WDS or Mesh links and result in user access failures. You are advised to run the capwap keep-alive times times-value command to set the number of heartbeat packet transmissions to 6 or a larger value.

  • In V200R007 and later versions, if WDS or Mesh is enabled simultaneously with dual-link backup, the AC sends CAPWAP heartbeat packets three times at an interval of 25 seconds by default. This may cause unstable WDS or Mesh links and result in user access failures. You are advised to run the capwap echo times times-value command to set the number of heartbeat packet transmissions to 6 or a larger value.
