This lesson provides an overview of the InfiLINK XG family units web interface for monitoring and configuration.

Web interface is a user-friendly management tool. Using Web interface, you can easily:

  • Monitor interfaces statistics of the unit .
  • Monitor radio link statistics.
  • View and change unit configuration.
  • Perform unit maintenance.
  • Realize an antenna alignment.
  • Run the Spectrum Analyzer and obtain a visual image of the radio signals sources.
  • Monitor the Instant DFS mechanism.

1. Conditions

Network Settings

The default management IP-address is and it can be used for initial login. Make sure that the PC Ethernet port has an IP-address assigned from the same subnetwork as the one for the unit (for example, set with mask

Username and Password

By default, no access settings are set on the units. On the login page, you can enter any username and any password.

  • Wireless Link Statistics: wireless link status, measured distance between devices, channel width, DL/UL Ratio, Frame Period.
  • Master and Slave parameters values in real time: Tx capacity, Tx/Rx frequency, DFS status, Tx/Rx Frames, MCS, CINR, RSSI, Acc TBER, etc.
  • Availability statistics with information about received and transmitted data for different coding schemes.
  • GNSS statistics if the GPS/GLONASS antenna is connected to the device and the "GNSS Receiver On" option is enabled.

  • Get info about the current firmware version and the last reboot reason.
  • Update the firmware version.
  • Download/upload license, softeware and configuration.
  • Get info about the current configuration and license.
  • Create a diagnostic card.
  • View and clear the system log.
  • Reboot the device.
  • Restore the factory settings.


The section is used to configure the device main system parameters.

Network Access

In this section network interfaces configuration is performed in order to obtain network access to the device.

Network Settings
  • Multiple IP-addresses can be assigned on network interface at the same time.
Static Routes
  • Specify the remote subnet in the field "Network" and the router IP-address adjacent to the device through which the specified subnet is accessible in "Gateway".


Section is used to configure the radio interface parameters. Below is the section structure and what should be taken into account when selecting and assigning radio parameters.

  • "Node Type" - one device must be set to master, other to slave. 
  • "Link ID" - must be the same on both ends of the same link. Use this parameter to avoid connecting a unit to a wrong peer if there are several co-located units using the same center frequency. 
  • "Traffic Prioritization" - 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.
  • "Security Key" - secret key word for encoding the protocol message, must be the same on both ends of the same link.
Air Frame
  • "Channel Width" - must be the same on both ends of the same link. 
  • "Frame Period" - must be the same on both ends of the same link. A shorter frame period gives lower latency, but also has higher overheads. Using longer frame periods cuts down overheads, but increases the latency. 
  • "Max Distance" - the specified value must not be lower than the actual link distance, but it is recommended keep it as close as possible to the actual distance to avoid unnecessary overheads. The recommended strategy is to set this parameter well above the actual distance after the units have been deployed based on the measured distance value taken from “xginfo stat” output.
  • The "Downlink Quota" parameter selection can be performed in manual or automatic mode. Available values depend from Channel Width, Frame Period, Max Distance and Short Cyclic Prefix. 
  • "TDD Sunchronization" - allows you to configure the TDD synchronization source:
    • "freerun" – the "slave" synchronization is performed with the built-in GPS/GLONASS receiver of the master. 
    • "gnss" – synchronization from the built-in GPS/GLONASS receiver. 
  • "Short Cyclic Prefix" - is used to mitigate inter-symbol interference due to multipath propagation environment. Cyclic prefix size is always 1/8 for 10 MHz channel width.
  • "Control Block Boost" - improves link availability in the most difficult propagation and interference conditions due to the radio frame with control information transfer at duplicate transmit power.
Radio Frontend
  • DL and UL Center Frequency must be the same on both ends of the same link. "Auto" will enable the Instant DFS mode.
Automatic Modulation and Transmit Power Control
  • "AMC Strategy" - strategy of the automatic modulation control mechanism:
    • "conservative" – 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. 
    • "normal" – represents a balance between the error rate and throughput values. 
  • "ATPC Master" - master manages the transmit power of the remote device in order to achieve the target RSSI value of its own receiver.
  • "ATPC Slave" - slave corrects the transmit power of its own transmitter according to the master directions. 
  • In general "ATPC Master" and "ATPC Slave" are not related to the "master" and "slave" parameters. The same unit can be as "ATPC Master" and "ATPC Slave".
Frequency Channel Grids
  • The licensed frequencies range per each bandwidth is displayed in "Default Channel Grids". 
  • Changes of the default frequency values can be performed in "Customer Channel Grid":
    • Limit the licensed frequencies range per each bandwidth. 
    • Change the center frequency step.


If you are not sure about the effect of the new configuration performed, you can set the safe mode by checking "Safe mode" box in the lower left corner of the page. The previous configuration is automatically restored after a period of 10 minutes in case the link between units was not established or link availability is less than 80%.


This section is intended for managing switch settings.

In order to better understand the switch principle on InfiLINK XG, let's review the switch block scheme.

The following 5 ports are available at the device:

  • External – physical ports for external devices connection:
    • ge0 and ge1 – copper Gigabit Ethernet ports 1000BASE-T (IEEE 802.1ab).
    • sfp – optical Gigabit port for plugging of the optical SFP transceiver module.
  • Internal – ports for device subsystems connection:
    • mgmt -  interface for the device management.
    • radio - port associated with the external radio interface for data transfer.

The SNMP protocol support is an important feature of all communication devices because it allows the system administrator to manage the operation of a network as a whole, as well as of each component. SNMP section contains a set of parameters to exchange data about network activity of the device.

The built-in alignment tool graphically shows the received signal levels for each polarization on both devices. The tool allows you to very accurately adjust the antenna position in both vertical and horizontal planes, allowing you to achieve the best RSSI and CINR values for each polarization.

  • RSSI – absolute level of the received radio signal (in dBm).
  • Crosstalk – indicates how much the vertically and horizontally polarized signals interfere each other (dB).
  • CINR – the signal quality.  For example, how strong is the carrier signal compared to the noise plus interference level, in dB.

Spectrum Analyzer

In the "Spectrum Analyzer" section, you can perform a deep analysis of the radio emissions in the environment where the device is placed. The device scans the radio spectrum on all available frequencies. In order to obtain the information as accurate as possible, the scanning process may take a while.

Instant DFS

Instant DFS tool allows to visualize the "Instant DFS" option statistics and gives the possibility to speed up the process of frequency reselection.


The "Graphs" section allows you to monitor the device parameters shown in the diagrams.

Available mode:

  • Real time;
  • Daily;
  • Weekly;
  • Monthly.

By default, the system displays a log of data for the day. You can select certain graphs of statistics that you are interested in at the moment.
