AP Mode Switching - Overview, Examples, and Troubleshooting

Introduction

This document describes AP modes and APs supporting mode switching, and provides detailed mode switching examples and troubleshooting measures.

Understanding Modes Supported by APs

APs can work in Fat, Fit, or cloud mode. By default, an AP works in Fit mode.

The AP9130DN supports only the Fat AP mode, and the AP5030DN-C supports only the cloud AP mode.

Starting from V200R023C10, SME Network APs work in cloud mode by default.

Table 1-1 AP mode description

AP Mode

Description

Application Scenario

Fat

Independent Fat AP deployment: A Fat AP independently provides Wi-Fi coverage and manages STA access, without the need of an additional management device. However, STAs cannot roam between Fat APs. Instead, STAs can access only the Wi-Fi network within the coverage area of the connected Fat AP.

As such, independent Fat APs are typically deployed to provide small-scale Wi-Fi coverage. In enterprise scenarios, the "AC + Fit AP" and "cloud management platform + cloud AP" networking modes are more commonly used.

Small-scale Wi-Fi coverage

Centralized leader AP + Fit AP deployment: The leader AP function is extended from Fat APs. Like an AC, a leader AP can be deployed to build a WLAN together with multiple Fit APs. On this WLAN, the Fat AP enabled with the leader AP function centrally manages and configures the Fit APs, enabling STAs to easily roam between the Fit APs. In the leader AP + Fit AP networking architecture, a Fat AP can be considered as a combination of an AC and a Fit AP. Without the leader AP function, the Fat AP can manage only its own Fit AP module. With the leader AP function configured, the Fat AP can also manage other Fit APs.

Small-scale and midsize Wi-Fi coverage

Fit

Fit APs cannot provide Wi-Fi coverage independently. They must work with an AC. The AC manages and controls all connected Fit APs. The AC delivers configurations to Fit APs in batches. Therefore, you do not need to configure Fit APs one by one. This greatly reduces WLAN management and maintenance costs. In addition, STAs can roam between Fit APs because user access authentication is managed by the AC in a unified manner. The "AC + Fit AP" networking mode is widely used for Wi-Fi network deployment in medium- and large-sized campuses, such as shopping malls, supermarkets, hotels, and enterprise offices.

In small Wi-Fi coverage scenarios, a small number of APs are required. If an additional AC is deployed, the cost of the entire wireless network is high. In such a scenario, Fat APs are recommended if wireless roaming is not required. If wireless roaming is required, cloud APs are recommended.

Medium- and large-sized campuses, such as shopping malls, supermarkets, hotels, and enterprise offices

Cloud

Cloud APs can be managed by the cloud management platform. Cloud APs provide similar functions as Fat APs, and can be deployed to build small networks. The cloud management platform + cloud AP networking mode is similar to the AC + Fit AP mode. Cloud APs are managed and controlled by the cloud management platform in a unified manner. Therefore, cloud APs can be applied to medium- and large-sized networks.

Cloud APs support plug-and-play and are easy to deploy. They can be flexibly expanded out of space restrictions. Therefore, cloud APs are widely used in multi-branch scenarios.

Wireless network scenarios of various scales, such as retail, small- and medium-sized enterprises, and hotels

Understanding APs Support Mode Switching

If an AP supports multiple modes, the AP supports mode switching. Most Huawei APs can switch between different modes. Only a few APs support only one mode, and therefore do not support mode switching. An AP may support different modes in different versions. For example, an AP may not support the cloud mode in V200R007C20 but support the cloud mode in V200R007C10 and V200R008.

To find out modes supported by a specified AP model or versions supported by a specified AP mode, refer to Quick Reference for WLAN AP Version Mapping and Models.

After downloading the table, filter out the specified AP model in AP Model. The following uses the AP4050DN as an example.

It is found that the AP4050DN can work in Fit or Fat mode starting from V200R007C20, and has also supported the cloud mode since V200R008C00.

How to Check the Current Working Mode of an AP

There are three methods for checking the current working mode of an AP:

  • Search for Wi-Fi signals on a mobile terminal (for example, a mobile phone). This method is applicable to the scenario where the AP is in factory defaults or offline state.

    Enable Wi-Fi on the mobile phone and search for Wi-Fi signals around the AP. Determine the AP's working mode according to the SSID format.

    If the SSID is in the format of HUAWEI-XXXX or HUAWEI-LeaderAP-XXXX, the AP is working in Fat mode. If the SSID format is hw_manage_xxxx, the AP is working in Fit or cloud mode.

    Starting from V200R023C00, the SSID name hw_manage_xxxx is changed to distinguish between the Fit and cloud modes: hw_manage_fit_xxxx for the Fit mode and hw_manage_cloud_xxxx for the cloud mode.

    An AP can transmit Wi-Fi signals in the following conditions:

    • Fit mode: An AP in factory defaults or offline state transmits signals of the Wi-Fi network with the SSID hw_manage_xxxx or hw_manage_fit_xxxx, where xxxx indicates the last 4 digits of the AP's MAC address.
    • Fat mode: From V200R019C10, an AP in factory defaults transmits signals of the Wi-Fi network with the SSID HUAWEI-LeaderAP-XXXX, which allows for direct access of mobile phones. XXXX indicates the last 4 digits of the AP's MAC address. Enter http://192.168.1.1 or http://169.254.2.1 in the browser. The login page of the web platform is displayed. For the sake of security, it is recommended that you delete the default SSID during AP configuration.
    • Cloud mode: An AP in factory defaults or offline state transmits signals of the Wi-Fi network with the SSID hw_manage_xxxx or hw_manage_cloud_xxxx, where xxxx indicates the last 4 digits of the AP's MAC address. In this way, mobile phones can directly access this SSID.

    Check the MAC address of an AP on the nameplate at the bottom of the AP.

    If the AP has been installed, move the mobile phone as close to the AP as possible. Typically, the SSID with the strongest signal strength is the SSID of the AP.

    This mode eliminates the need of an Ethernet cable but is not applicable to any scenario. APs only in the specified state and version can transmit Wi-Fi signals. This method allows you to determine the working mode of the AP whose state and version you are not sure of. If the working mode of the AP cannot be determined, connect a PC to the AP using an Ethernet cable.

    If no Wi-Fi signal of the specified SSID is found, connect a PC to the AP and log in to the AP.

  • Log in to the AP and check its working mode using the CLI. Connect a PC to the AP using an Ethernet cable. Enter identity information and log in to the AP. The working mode of the AP is automatically displayed.

    Connect a PC to the AP. Configure the IP address for the PC to locate on the same network segment as the AP. For the connection mode, see Figure 1-1.

    Figure 1-1 AP-PC connection diagram

    On the PC, log in to the AP using an SSH client. The working mode of the AP is displayed upon successful login.

    Info: Current mode: Fit (managed by the AC).
  • Log in to the AP and check its working mode on the web platform. Connect a PC to the AP using an Ethernet cable. Enter the AP's IP address in the browser. The AP's working mode is automatically displayed on the login page.

    Connect a PC to the AP. Configure the IP address for the PC to locate on the same network segment as the AP. For the connection mode, see Figure 1-1.

    Open the browser on the PC and enter the http://IP address. The default IP address of an AP is 169.254.1.1 (the default IP address of an RU is 169.254.1.2). The current working mode of the AP is displayed. For details about cable connections, see AP Mode Switching Examples.

    • Fit mode: Fit is displayed.

    • Fat mode: Access Point is displayed on the login page.

    • Cloud mode: Cloud Access Point is displayed on the login page.

How to Switch the Working Mode of an AP

In V200R019C00 and earlier versions, the requirements for AP mode switching are as follows:
  • Switching between the Fat and cloud modes

    You can directly switch an AP that uses the same system software between the Fat and cloud modes in any circumstance.

  • Switching between the Fit and Fat modes or between the Fit and cloud modes
    • Some APs support one software package for both the Fat and cloud modes, for example, 802.11ac Wave 2 APs. The working mode of such APs can be directly switched before delivery. If an AP has been upgraded, switched the mode, or been online on an AC, configure the FTP server and download the corresponding software package to switch the working mode of the AP.

      These APs include 802.11ac Wave 2 APs, AP7060DN, AirEngine 5760-10, SME Network series APs, as well as the AP8030DN, AP8130DN, AD9430DN-12, and AD9430DN-24 in V200R007 and later versions.

    • Some APs support one software package for only one working mode, for example, 802.11n APs and some 802.11ac APs. To switch the working mode of such APs, configure the FTP server and download the corresponding software package.

      These APs include 802.11n APs, AP3010DN-V2, AP3030DN, AP4030DN, AP4030DN-E, AP4130DN, AP5030DN, AP5030DN-S, AP5130DN, AP9131DN, AP9132DN, as well as the AP8030DN, AP8130DN, AD9430DN-12, and AD9430DN-24 in V200R006 and earlier versions.

In V200R019C10 and later versions, APs support one software package for the Fat, Fit, and cloud modes. Therefore, the working mode of such APs can be directly switched Fat, Fit, and cloud modes. This is supported by AirEngine series APs (except RUs) and SME Network series APs.
