Quanta 5 web interface is an intuitive and responsive user interface adjusts the layout based on the size of your screen. Essential tools such as antenna alignment and spectrum analyzer are included to make set-up and troubleshooting more efficient. Automatic mechanisms such as auto-channel and automatic transmit power control optimize the link for maximum performance even in areas with high interference.

1.Introduction

Network settings

By default wireless device has IP address 10.10.10.1 with 255.255.255.0 network mask. The workstation used to perform initial configuration must have an IP address from the same subnet.

Login and Password

By default no login or password are set, use any letters or numbers for initial authentication.

2. Web Interface

Navigation in the web interface is performed using the side menu, which includes the following sections:

  • Dashboard.
  • Settings.
  • Service.

Dashboard

This section displays the following wireless real time statistics:

  • Connection status, information about the distance and link operation time.
  • Link parameters: center frequency, channel width, frame length, and the uplink/downlink ratio.
  • Link load and the retries number.
  • The current modulation and coding scheme, RSSI and CINR values for each polarization on the local and remote devices.

Settings

General

The section is designed to configure the basic system parameters of the device.

Unit:

  • Device name - is an arbitrary set of characters. Is used for easy device identification by the network administrator, is displayed in the web interface in the "Dashboard" section.
  • Link ID - allows to avoid connecting to wrong devices in case of several adjacent links. Must be the same at both sides of the link.


Regulatory domain:

  • Allows to set complex system limitation in accordance with the requirements of local legislation, it makes configuration process easyer.
  • Restrictions are applied to the following parameters:
    • Available frequency range.
    • Use of LBT (Listen Before Talk) technology.
    • Maximum EIRP value.
    • Radar detection performing.

SNTP

Starts the SNTP time synchronization service. For proper operation, specify the SNTP server time zone and the IP address first. By default, the SNTP service is disabled.

  • SNTP Server Address - The SNTP server IP address, the SNTP service will synchronize the time on the device with. The device must have network access to the SNTP server.
  • Time Zone - The time zone at the place of device installation. For example: GMT + 5.

Security

This section allows to configure device access and security settings.

Administrator access

  • Here you may change system administrator account login and password, to change the identification data, click the "Change admin password" button. We strongly recommend you to set a login and password after the first login to the device.

Radius AAA

  • Here you may configure a device access control using a remote RADIUS server.
    • Address - set the RADIUS server IP address.
    • Port - set the RADIUS server port.
    • Secret - set the server password.

Command line interface

  • Allows to enable / disable remote device control by the command line using Telnet and SSH protocols.
  • SSH (Secure Shell) protocol provides secure remote control to network devices. Its functionality is similar to the Telnet protocol, but, unlike Telnet, SSH encodes all protocol messages, including transmitted passwords. By default, only access via Telnet is enabled.

Network access

  • This section is used to create a list of subnets from which access to the device will be allowed.

Radio authentication settings

  • Units at both ends of the wireless link should authorize each other before link establishment. Access key must be up to 64 characters long, without spaces and must be the same at both ends of the link.
Radio

The section includes the radio subsystem parameters necessary for wireless link establishing.

Radio frontend:

  • Unit role - one of the devices must be "Master", the second - "Slave".
  • Automatic selection of center frequency has the following modes:
    • Frequency selection off - frequency should be set manualy.
    • Dynamic frequency selection - the least noisy frequency will be selected automaticaly according to frequency channel grids.
    • Insant DFS - center frequency will be set automatically according to frequency channel grids. Unit will switch to the different frequency if high level interference will be detected.
    • Instant DFS and radar detection - center frequency will be set automatically according to frequency channel grids. Unit will switch to the different frequency if high level interference or radar will be detected.
  • Fixed center frequency - available only on Slave unit. If enabled, the center frequency must be set manually, otherwise the frequency is automatically selected in accordance to frequency channel grids by scanning spectrum for Master unit.
  • Downlink/Uplink center frequency - allows to set manually the center frequency, can be the same for uplink and downlink direction or different. Uplink center frequency is available only for Master.
  • Power limit - two ways of power limiting are available:
    • Transmitter power output - limits transmitter power to a specified value.
    • EIRP - limits the overall system transmitted power, calculated by the formula: transmitter power + antenna gain - RF cable loss (gain and loss should be set in the fields below).

Air frame:

  • Channel width - must be the same at both sides of the link. Available values: 3.5, 5, 7, 10, 14, 15, 20, 28, 30, 40, 50, 56 MHz.
  • Frame length:
    • The greater frame length the more payload will be transmitted in one frame. Greater values increase latency.
    • The lower frame length the less payload will be transmitted in one frame. Lower values decrease latency.
    • Available values: 1, 2, 5, 10 ms.
  • Guard interval - is intended for intersymbol interference elimination. One of the intersymbol interference reasons is multipath propagation in which a wireless signal from a transmitter reaches the receiver via multiple paths. Guard interval affects payload size. So it should be increased only in case of significant intersymbol interference. Available values: 1/8 and 1/16.
  • Downlink/Uplink ratio - available only on Master unit. In automatic mode, the ratio changes dynamically in accordance with the transmitted traffic. Manual mode allows to set a fixed value using the slider.

Automatic modulation and transmit power control:

  • AMC strategy - allows to select a strategy of modulation switching for cases when the transmission medium conditions change. The following strategies are available:
    • Normal - keeps balance between the number of errors and bandwidth.
    • Conservative - assumes using higher CINR thresholds in order to minimize the error rate.
    • Aggressive - lowers the thresholds in order to use higher modulation levels and thus increase the throughput.
  • Automatic transmit power control - controls transmitter output power automatically based on target RSSI value. If actual RSSI level is lower then unit increases transmitter output power of the remote unit and vice versa. ATPC could not set value that may exceed the "Power limit" value.
  • Target RSSI - RSSI value which will be used by ATPC as target.

Frequency channel grids for each channel width:

The frequency grid allows to limit the scan range in case the center frequency is automatically selected. Also Instant DFS will use these restrictions when monitoring the noise situation. Narrow grid of available frequencies speeds up scanning and link establishing process. Manual center frequency selection will also be limited to the values indicated in the grid.

Network

This section allows to assign an IP address or several addresses to the wired interface, the default gateway value can also be specified.

Click the "Add IP address" button to add a new address. There are two ways to assign an IP address:

  • Automatically - the IP address will be obtained automatically from the DHCP server.
  • Manual - the IP address and netmask are specified manually.

The VLAN tag value can also be set in this section, the VLAN ID value should be in range from 1 to 4096.

Switch

Network ports

Each Quanta 5 family device has 3 ports:

  • ge0 - Gigabit Ethernet 1000BASE-T port.
  • radio - internal radio interface.
  • mgmt - internal interface for device management.

Only ge0 interface is available to configure. The following parameters can be changed:

  • Status - enabled/disabled.
  • Duplex - duplex mode, "auto" is by default.
  • Description - arbitrary text description.

QoS

Enable/disable prioritization strategy. Unit will recognize the 802.1p tags in Ethernet frame headers. Based on these tags priorities will be autlomatically assigned to the frames when they are sent over the radio interface. After transmission over radio interface frames with tags are sent to Ethernet. Priorities may be adjusted manually if a VLAN based switching is enabled.

VLAN based switching

VLAN based switching allows to create list of allowed VLANs and their handling on the unit switch plane. If VLAN based switching is enabled but no VLANs are added, device ports will allow untagged traffic only. Each entry of list establishes the relationship between VLAN ID and ports VLAN modes. "VLAN 1" is created by default and could not be deleted, it's enough to set all interfaces to "off" mode to disable it.

  • VLAN ID - VLAN tag in range from 1 to 4095. May be set in a few ways, examples:
    • 12
    • 10-20
    • 100,200,300
    • 23,24,25,50-100
  • Description - arbitrary text description.
  • Priority - allows to set the priority of a specific VLAN according to 802.1p ranging from 0 to 7, where 0 - the lowest priority level, 7 - the highest, the QoS support function must be enabled.
  • Port mode - VLAN mode should be set for each of network ports. Mode determines the way which VLAN tagged network packets will be handled by switch. There are three ports modes:
    • Off - denies all traffic of a specified VLAN. If none of the modes is selected, the port will be marked as "Off".
    • Access - operates as access port, allows only untagged traffic.
    • Tagged - operates as trunk port, allows tagged traffic of a specific VLAN to pass through this port.
    • Untagged - operates as trunk port, allows untagged traffic of a specific VLAN to pass through this port.
Configuration example

Scenario: PC 1 - untagged traffic and PC 2 - tagged traffic with VLAN 20.

Purpose: Enable communication between PC1 and PC2.

  • Configuration on the Master: configure VLAN 20 and set it to “Untagged” on both ge0 and radio ports.
  • Configuration on the Slave: configure VLAN 20 and set it to “Tagged” on ge0 and "Untagged" on the radio port.

Make sure VLAN based switching is enabled.


 
Connectivity matrix

Allows to configure the traffic transfer between the network ports of the device. Configuration is performed visually using switches. The green switch indicates allowed connections, the red one - denied:

  • ge0 - Gigabit Ethernet port.
  • radio - internal radio interface.
  • mgmt - internal interface for device management.

Traffic flow between ports is performed in accordance with VLAN modes set, if the VLAN based switching is enabled.

SNMP

SNMP allows the administrator to gather information about key device parameters and wireless links, including information about changes. The use of InfiMONITOR or any other monitoring system helps to timely receive information about the network infrastructure state using InfiNet devices. Currently, the Vector 5 devices family supports SNMP protocol versions v.1 and v.2c.

The SNMP Protocol has two sides, the agent and the management stations:

  • The agent sends data to the management station. Monitoring system - provides data gathering from all agents in the network.
  • The monitoring system receives and processes events.
  • The information is passed through requests and replies with the use of the MIB
  • The management station or monitoring system is responsible for decoding the SNMP packets and providing an interface to the administrator.


  • Enabled - enable/disable SNMP daemon in the device.
  • Contact person - a reference information about the device owner.
  • Location - the geographical location where the unit is installed, used as a reference information about physical device’s location.

SNMP v1/v2c

  • Enabledenable/disable SNMP v.1 and v.2c support. The first version of the SNMP protocol lacks security, that hinders its use for network management, so SNMP v.1 and v.2c operates in read-only mode. Enabled by default.
  • Community - set the community name for read-only mode of SNMP v.1 and v.2c, by default: "public". The community name passes along with the data packet in clear text.
