Configuring WTs

Support for the IoT capability depends on the WT model.
This chapter contains basic WT configuration. For information about IoT configuration, see IoT AP configuration in the Internet of Things Configuration Guide.
You can configure 2 × 2 MIMO on WTU420 and WTU420H, but the configuration will not take effect.

About the wireless terminator solution

The wireless terminator solution is a new-generation wireless network structure proposed for the large-scale and intensive deployment of WLANs at a low cost.

Network topology

Basic networking scheme
As shown in Figure 1, the basic network in a wireless terminator solution includes the following entities:

• Wireless terminator—A WT is an AP that associates with the AC on behalf of WTUs and connects to IoT modules through wired cables. It offers a PoE power supply and data forwarding for the WTUs and IoT modules.
• Wireless terminator unit—A WTU is an indoor AP that only sends and receives wireless packets. A WTU supports 802.11ac Gigabit wireless access, and it can operate simultaneously in 2.4 GHz and 5 GHz bands.
• AC—Manages the WT, the WTUs, and the IoT modules.
• IoT module—An IoT module acts as a sensor to connect things to the Internet for intelligent identification, locating, tracking, monitoring, and management of things.

Figure 1 Basic networking scheme of wireless terminator solution

Cascade networking scheme
NOTE:
Support for the cascade networking scheme depends on the WT model.
As shown in Figure 2, the cascade network in a wireless terminator solution includes the following entities:

• Wireless terminator 1—An AP connected to wireless terminator 2 through wired cables. It offers a PoE power supply and data forwarding for wireless terminator 2.
• Wireless terminator 2—An AP that associates with the AC on behalf of WTUs and connects to IoT modules through wired cables. It offers a PoE power supply and data forwarding for the WTUs and IoT modules.
• Wireless terminator unit—A WTU is an indoor AP that only sends and receives wireless packets. A WTU supports 802.11ac Gigabit wireless access, and it can operate simultaneously in 2.4 GHz and 5 GHz bands.
• AC—Manages the WT, the WTUs, and the IoT modules.
• IoT module—An IoT module acts as a sensor to connect things to the Internet for intelligent identification, locating, tracking, monitoring, and management of things.

Application scenarios and advantages

The wireless terminator solution can be widely applied to scenarios such as dormitories, apartments, hotels, small-sized offices, and medical institutions, and intelligent campuses. This solution has the following advantages over traditional independent or indoor solutions:

• Cost-saving and easy deployment—A WT and WTUs are connected through Ethernet cables instead of dedicated lines. The WT directly supplies power to the WTUs through PoE.
• Strong signal strength—Each room has dedicated bandwidth.
• Enhanced network performance and user experience—WTUs can offer high uplink bandwidth.
• Most up-to-date wireless access technology—WTUs support 802.11ac Gigabit and dual-band access.
• Support for IoT module connection—A WT can connect to IoT modules to provide more services besides wireless services, which is cost-saving and easy to manage.

Restrictions and guidelines: WT configuration

You can configure APs by using the following methods:

• Configure APs one by one in AP view.
• Assign APs to an AP group and configure the AP group in the AP group view.
• Configure all APs in the global configuration view.

For an AP, the settings made in these views for the same parameter take effect in descending order of AP view, AP group view, and global configuration view.

WT tasks at a glance

To configure a WT, perform the following tasks:

• Configuring PoE for a WTU port
• Specifying the WT version
• Enabling port type switching

Configuring PoE for a WTU port

About this task
A WT uses WTU ports to supply power to its connected WTUs through PoE. For a WTU to operate correctly, make sure PoE is enabled for the WTU port that connects the WT to the WTU.
Procedure

1. Enter system view.
   system-view
2. Enter AP view or an AP group’s AP model view.
   •Enter AP view. WLAN ap ap-name
   •Execute the following commands in sequence to enter an AP group’s AP model view:
   WLAN ap-group group-name ap-model ap-model
   The AP must be a WT.
3. Configure PoE for a WTU port.
   Poe was-port port-number1 [ to port-number2 ] { disable | enable }By default:
   •In the AP view, an AP uses the configuration in an AP group’s AP model view.
   •In an AP group’s AP model view, PoE is enabled for a WTU port.

Specifying the WT version

NOTE:
Support for this feature depends on the WT model.
Restrictions and guidelines
If the specified WT version is different from the WT version in use, the WT will restart automatically.
Then, it will switch to the specified WT version and restore the factory settings.
This command does not take effect on WTs that support different types of WTUs.
Procedure

1. Enter system view.
   system-view
2. Enter AP view or an AP group’s AP model view.
   •Enter AP view.
   WLAN ap ap-name
   •Execute the following commands in sequence to enter an AP group’s AP model view:
   WLAN ap-group group-name ap-model ap-model
   The AP must be a WT.
3. Specify the WT version.
   wt version { 1 | 2 | 3 }
   By default:
   •In the AP view, an AP uses the configuration in an AP group’s AP model view.
   •In an AP group’s AP model view, the WT version varies by AP model.

Enabling port type switching

About this task
You can switch an Ethernet port on a WT to a WTU port to increase the number of WTU ports or switch a WTU port to an Ethernet port.
If a port has a mark of two different port names separated by a slash (/), G3/WTU26 for example, the port supports port type switching
Restrictions and guidelines

CAUTION:
To prevent the chips on the connection from being damaged because of PoE power supply capacity change, make sure the port to switch is not connected to any other device.
This command will reboot the WT and the new port will use its default settings.

Procedure

1. Enter system view.
   system-view
2. Enter AP view or an AP group’s AP model view.
   •Enter AP view.
   WLAN ap ap-name
   •Execute the following commands in sequence to enter an AP group’s AP model view:
   WLAN ap-group group-name
   ap-model ap-model
   The AP must be a WT.
3. Enable port type switching between an Ethernet port and a WTU port.
   port-type switch number port-number-list { gigabit ethernet | with }
   By default:
   •In the AP view, an AP uses the configuration in an AP group’s AP model view.
   •In an AP group’s AP model view, the default setting varies by WT model.
   Support for this command depends on the WT model.

Display and maintenance commands for WTs

The AP models and serial numbers in this document are used only as examples. Support for AP models and serial numbers depends on the AC model.
Execute display commands in any view.
