Device description

Purpose

The wireless access points WEP-30L and WEP-30L-Z are designed to provide the user access to high-speed and secure network.

The main purpose of the devices is to create a Layer 2 wireless network at the junction with a wired network. WEP-30L and WEP-30L-Z connect to a wired network over 10/100/1000/2500M Ethernet interface and using radio interfaces create wireless high-speed access for devices that support Wi-Fi technology in the 2.4 GHz and 5 GHz bands.

The devices contain 2 radio interfaces for organizing two physical wireless networks.

WEP-30L-Z has a built-in IoT Hub compatible with Z-Wave devices from ELTEX, to interact with IoT ecosystem sensors and devices and to manage them through the Eltex Smart Cloud (Eltex SC) platform.

WEP-30L and WEP-30L-Z support modern quality of service requirements and allow one to transmit the most important traffic in higher priority queues than normal. Prioritization is provided by the following QoS technologies: CoS (special tags in the VLAN packet field) and ToS (tags in the IP packet field). Support for traffic shaping on each VAP allows one to fully manage access, quality of service and restrictions both for all subscribers and for everyone in particular.

The devices are designed for installation in offices (government institutions, conference rooms, laboratories, hotels, etc.). Ability to create virtual hotspots with different encryption types allows one to place WEP-30L and WEP-30L-Z in organizations where separation of access rights is required between ordinary users and dedicated user groups.

Rules and recommendations for device installation

This section defines safety rules, installation recommendations, setup procedure and the device starting procedure.

Safety rules

1. Do not install the device near heat source and at places where temperature may reach values below
   +5 °C or higher +40 °C.
2. Do not use the device in rooms with high humidity. Do not expose the device to smoke, dust, water, mechanical vibration or shock.
3. Do not open the device case. There are no user serviceable parts inside.

Installation recommendations

1. The recommended installation position: horizontal, on the ceiling.

2. Before installing the device and turning it on, check the device for visible mechanical defects. If defects are observed, stop the device installation, fill in the corresponding act and contact the supplier.

3. If your device has been exposed to the cold for a long period of time, let it warm up at room temperature for two hours before starting work. If your device has been exposed to high humidity for a long period of time, let it stay under normal conditions for at least 12 hours before turning it on.

4. When placing your device, in order to provide the best Wi-Fi coverage consider the following rules: 

• Install the device at the center of a wireless network;
• Minimize the number of barriers (walls, ceilings, furniture, and etc.) between WEP-30L/WEP-30L-Z and other wireless network devices;
• Do not install the device near (about 2 m) electrical and radio devices;
• It is not recommended to use radiophone and other equipment operating at the frequency of 2.4 GHz or 5 GHz, within the range of a Wi-Fi network;
• Obstacles like glass/metal constructions, brick/concrete walls, water cans and mirrors can significantly reduce Wi-Fi action radius. It is not recommended to place the device inside a false ceiling as metal frame causes multipath signal propagation and signal attenuation.

5. When installing several access points, cell action radius must overlap with action radius of a neighboring cell at the level from -65 to -70 dBm. It is allowed to reduce the signal level to -75 dBm at cell boundaries, if it is not intended to use VoIP, video streaming and other sensitive to losses traffic in wireless network.

Calculating the number of required access points

To calculate the required number of access points, evaluate the required coverage zone. For more accurate assessment, it is necessary to make a radio examination of the room. Approximate radius of WEP-30L and WEP-30L-Z coverage area with a good-quality signal in case of mounting on a ceiling in typical office:
2.4 GHz — 40–50 m, 5 GHz — 20–30 m. In the absence of obstacles, the coverage radius: 2.4 GHz — up to
100 m, 5 GHz — up to 60 m. Table 5 describes rough attenuation values. 

Table 5 — Attenuation values

Channel selection for neighboring access points

It is recommended to set non-overlapping channels to avoid inter-channel interference among neighboring access points.

 
Figure 4 – General diagram of frequency channel overlap in the range of 2.4 GHz

Example of channel allocation scheme among neighboring access points in frequency range of 2.4 GHz when channel width is 20 MHz, see Figure 5.

Figure 5 – Scheme of channel allocation among neighboring access points in the frequency range of 2.4 GHz when channel width is 20 MHz

Similarly, the procedure of channel allocation is recommended to save for access point allocation between floors, see Figure 6.

Figure 6 – Scheme of channel allocation between neighboring access points that are located between floors

With a channel width of 40 MHz there are no non-overlapping channels in the 2.4 GHz band. In such cases, you should select channels maximally separated from each other.

Figure 7 – Channels used in the 5 GHz band when channel width is 20, 40 or 80 MHz

• Auto Channel — when checked, the device will automatically select the least congested radio channel for the Wi-Fi interface. Unchecking the flag opens the access to install the static operation channel;
• Channel — select channel for data transmission;
• Use Limit Channels — when checked, the access point will use a user-defined list of channels to work in automatic channel selection mode. If the “Use Limit channels” flag is not checked or there are no channels in the list, the access point will select the operation channel from all available channels in the given band. 2.4 GHz band channels: 1–13;
• Channel Bandwidth, MHz — channel bandwidth, on which the access point operates. The parameter may take values 20 and 40 MHz;
• Primary Channel — parameter can only be changed if the bandwidth of a statically specified channel is equal to 40 MHz. The 40 MHz channel can be considered as consisting of two 20 MHz channels, which border in the frequency range. These two 20 MHz channels are called primary and secondary channels. The primary channel is used by clients who only support 20 MHz channel bandwidth:
  • Upper — primary channel will be the upper 20 MHz channel in the 40 MHz band;

• Fragmentation Threshold — frame fragmentation threshold, bytes. The parameter takes values 256–2346, by default: 2346;
• RTS Threshold — specifies the number of bytes over which the Request to Send will be sent. Decreasing this value may improve the performance of the access point when there are a lot of connected clients. However this reduces general throughput of wireless network. The parameter takes values from 0 to 2347, by default: 2347; 
• Frame aggregation — enable support for AMPDU/AMSDU;
• Short Preamble — use of the packet short preamble;
• Broadcast/Multicast Rate Limiting, p/s — when the flag is set, transmission of broadcast / multicast traffic over the wireless network is restricted. Specify the limit for broadcast traffic in the popup window (p/s);
• Wi-Fi Multimedia (WMM) — WMM support activation (Wi-Fi Multimedia);
• DHCP Snooping Mode— selection of  DHCP option 82 processing policy. Available values for selection:
  • ignore  — option 82 processing is disabled. Default value;

      • ClientMAC — change the RID content to the MAC address of the client device. Default value; 
      • APMAC — change the RID content to the MAC address of the access point;
      • APdomain — change the RID content to the domain in which the access point is located;
      • custom — change the RID content to the value specified in the "Option 82 Unique RID";
        • Option 82 Unique RID — an arbitrary string of up to 63 characters that will be passed to the RID. If the parameter value is not set, the point will change the RID to the default value — ClientMAC.

  • IEEE 802.11ax;
  • IEEE 802.11a/n/ac;
  • IEEE 802.11a/n/ac/ax.
• Auto Channel — when checked, the device will automatically select the least congested radio channel for the Wi-Fi interface. Removing the flag opens the access to install the static operation channel;
• Channel — select channel for data transmission;
• Use Limit Channels — when checked, the access point will use a user-defined list of channels to work in automatic channel selection mode. If the “Use Limit channels” flag is not checked or there are no channels in the list, the access point will select the operation channel from all available channels in the given band. 5 GHz band channels: 36–64, 132–144, 149–165;
• Channel Bandwidth, MHz — channel bandwidth, on which the access point operates. The parameter may take values of 20, 40 and 80 MHz;
• Primary Channel — parameter can only be changed if the bandwidth of a statically specified channel is equal to 40 MHz. The 40 MHz channel can be considered as consisting of two 20 MHz channels, which border in the frequency range. These two 20 MHz channels are called primary and secondary channels. The primary channel is used by clients who only support 20 MHz channel bandwidth:
  • Upper — primary channel will be the upper 20 MHz channel in the 40 MHz band;
  • Lower — primary channel will be the lower 20 MHz channel in the 40 MHz band.
• Transmission Power Limit, dBm — transmitting Wi-Fi signal power adjustment, dBm. May take values between 0 and 19 dBm.

Managing the device using the command line

Connection to the device

By default, WEP-30L/WEP-30L-Z is configured to receive the address via DHCP. If this does not happen, you can connect to the device using the factory IP address. 

Connection to the device is performed via SSH/Telnet:

Network parameters configuration

Network parameters configuration via set-management-vlan-mode utility

IPv6 network parameters configuration

Similar to restricting access to the device via the TELNET protocol, you can restrict the ability to connection to the device by its IPv6 address using the following protocols: SSH, SNMP, NETCONF, web, web-HTTPS. 

Virtual Wi-Fi access points (VAP) configuration

When configuring a VAP, remember that the interface names in the 2.4 GHz band start with wlan0, in the 5 GHz band with wlan1.

Table 8 — Commands for configuring security mode on VAP

Below are examples of VAP configuration with different security modes for Radio 5 GHz (wlan1).

Configuration of VAP without encryption

Configuration of VAP with OWE encryption

Configuration of VAP with OWE and OWE Transition Mode 

Configuration of VAP with WPA-Personal security mode

Configuration of VAP with Enterprise authorization

Configuration of VAP with Captive Portal

Configuration of VAP with external Captive Portal 

Table 9 — Setting up a URL template for external Captive Portal 

Advanced VAP settings

802.11r configuration

This type of roaming is available only for client devices supporting 802.11r.

802.11r roaming is possible only between VAPs with WPA2/WPA3-Personal and WPA2/WPA3-Enterprise security modes.

See instructions for configuring VAP with WPA2-Personal security mode and others in Configuration of VAP with WPA-Personal security mode section.

Each VAP on the access points should be configured individually, eg. AP1(wlan1)↔AP2(wlan1), AP1(wlan0)↔AP2(wlan0), AP1(wlan1)↔AP3(wlan1), etc.

Below is the example of 802.11r configuring on two access points: AP1 and AP2.

802.11k configuration

802.11k protocol roaming can be organized between any networks (open/secure). If the access point is configured to work using the 802.11k protocol, then when a client connects, the access point sends the list of “friendly” access points to which a client can switch in a roaming process. The list contains information about access points' MAC addresses and channels they work with.

The use of 802.11k allows to reduce the time for finding another network when roaming, since the client does not need to scan channels on which there are no target access points available for switching.

This type of roaming is available only for client devices supporting 802.11k.

Below is the example of 802.11k configuring access point — making a list of “friendly” access points.

Radio configuration 

In the Radio section, automatic selection of the working channel is used by default. To set the channel manually and change the power, use the following commands:

Advanced Radio settings

The configuration method of edca-sta is the same as that of edca-ap.
Parameters configuration for queues be, vi, vo is similar to parameters configuration for queue bk.

Configuring DHCP option 82 

DHCP snooping operating modes:

• ignore – option 82 processing is disabled. Default value;
• replace – access point substitutes or replaces the value of option 82; 
• remove – access point removes the value of option 82.

If on the radio interface the 82 option processing policy is configured to replace, the following parameters become available for configuration:

Configuring WDS

The configuration of a WDS connection on the 5 GHz Radio interface (wlan1) is described below.

The configuration of the remote access point is done in a similar way.

Configuring Z-Wave 

System settings

Device firmware update

Device configuration management

Device reboot

Configuring the authentication mode

The device has a factory user account of admin with a password of password. This account cannot be deleted. You can change your password using the following commands.

It is possible to create additional users for local authentication as well as authentication via RADIUS.

To authenticate via a RADIUS server, you need to configure access parameters to it.

Setting the date and time

Advanced system settings

Configuring Captive Portal 

Portal Certificate Management

Configuring APB service 

The APB service is used to provide portal roaming of clients between access points connected to the service. 

Configuring remote traffic dump capture

The remote-capture section performs remote recording of a traffic dump.
The device supports the RPCAP protocol, which allows recording a traffic dump from the device interface on a remote machine in online mode.

For remote connection, use the RPCAP protocol, specify the device IP address and port. For this, for example, one can use the Wireshark program. Then it is required to get a list of interfaces for sniffing from the device, select one of them and start dumping from the remote interface.

tcpdump utility

The tcpdump utility allows capturing packets on the specified interface.

To get a hint on how to work with the utility use the command: 

Traffic capture from any active interface

For example, it is possible to enable packet capture on the Ethernet interface. 

Environment sniffer

It is necessary to enable a special interface that catches all packets from the air on the working channel of the AP. 

iperf utility 

This utility is used to start a traffic flow from one device to another. The sending side is called the client, the receiving side is called the server.

To get a hint on how to work with the utility use the command: 

Example of starting a traffic flow from the access point to the server:
