All these counters can be reset by clicking the «Reset All Counters» button.

Switch Statistics parameters:

ParameterDescription
Unicast
  • Sending a packet to a single host (network destination) identified by a unique address
Broadcast
  • Sending a packet to all hosts (network destinations) simultaneously (broadcasting is done by specifying a special broadcast address on packets)
Flood
  • Sending a packet along the same link multiple times (without specifying a destination address for the packets)
  • Several copies of the same packet would ultimately reach all nodes in the network in flooding
STP
  • Spanning Tree Protocol - standardized as IEEE 802.1D
  • Creates a spanning tree within a network of connected layer-2 bridges (typically Ethernet switches) and disables those links that are not part of the spanning tree, leaving a single active path between any two network nodes
  • The value displayed in the Switch Statistics table represents the number of the packets blocked by the Spanning Tree Protocol
Unreachable
  • The sender could not reach the specified network destination
  • The value displayed in the Switch Statistics table represents the number of the packets dropped because they flood to unreachable destination

Firewall

  • A software or hardware-based network security system that controls the incoming and outgoing network traffic by analyzing the data packets and determining whether they should be allowed through or not, based on applied rules set
  • The value displayed in the Switch Statistics table represents the number of the packets dropped by the firewall system in the network
Possible loop
  • A switching or bridging loop occurs in a network when there is more than one Layer 2 path between two endpoints
  • Because a physical topology that contains switching or bridging loops is needed for the redundancy reasons, the solution is to allow physical loops, but create a loop-free logical topology using the spanning tree protocol (STP) on the network switches
  • The value displayed in the Switch Statistics table represents the number of the packets dropped because they belong to a possible loop (more than one port declares same packet source)
Discard
  • The value displayed in the Switch Statistics table represents the number of the packets dropped by the configuration (for example: "switch group N start [discard]")
MAC Limit
  • MAC address-table limit reached (switch maxsources (MAXSOURCES|0) # default 5000)
  • The value displayed in the Switch Statistics table represents the number of the packets dropped because the limit of MAC address-table was reached
Reverse
  • The value displayed in the Switch Statistics table represents the number of the packets dropped because they have the same source and destination port (the frame came to the unit through one port and according to the switching table it must leave through the same port)

QoS Statistics

QoS (Quality of Service) characterizes the entire network performance which is defined by the parameters such as: throughput, latency, jitter, error rate, available bandwidth, etc. In order to provide the guaranteed Quality of Service for certain applications, users or data flows, different prioritization methods are used.

The "QoS Statistics" tool displays the statistics of the MINT priority queues for the interface.

Priority is one of the parameters which define in what sequence, different types of data traversing every InfiNet device in MINT network are treated. Each channel may be assigned a priority (for example: P01, P02 … P16).

Once assigned, a priority is automatically recognized by every node inside the MINT network. Each priority value corresponds to a device queue. Once in a queue, every packet is scheduled according to the queuing algorithm set on the device. QM manager supports "Strict Priority Queuing" and "Weighted Fair Queuing" scheduling algorithms. "Strict Priority Queuing" means that the packets from queue with lower priority are not processed until the queue with higher priority is not empty. "Weighted Fair Queuing" uses weights for every queue of an interface and allows different queues to have different service shares, depending on that weight.

Every channel is also characterized by the latency parameter. This parameter determines the maximum time for the packets to stay in the channel. If a packet is waiting in a queue of the channel more than the time specified in the latency parameter, then it is discarded. Latency can be set for each channel in the "Traffic Shaping" section.

Extended Link Diagnostics

Once a wireless connection between the unit and the remote neighbor is established, it is possible to make extended diagnostics and optimization for the wireless link.

In order to access the "Extended Link Diagnostics" tools, click on the row of each wireless link within the "Links Statistics on rf5.0" section:

Figure - Extended Link Diagnostics

Five options are available: "Performance Tests", "Antenna Alignment Tool", "Statistics Graphs", "Remote Commands" and "Link Restart".

Performance tests

The "Performance tests" tool performs link throughput tests for the configured channel bandwidth and on the current frequency, without radio link interruption.

The "Performance tests" tool generates traffic between the devices and displays the channel throughput for the traffic with chosen priority. For the full throughput tests of the channel, you must set the highest priority “0” for the test traffic. In this case, the transmission of any other traffic is stopped for the testing time and the traffic generated by the tool will occupy all the channel.

The "Performance tests" tool displays the values of the full channel throughput which is available under the current settings, for each bitrate.

NOTE

 All results are given in kilobits per second and retries levels are shown as a red chart.

Performance tests for "MINT" and "TDMA" firmware are not the same. There are two tests in "MINT": one with graduation on bitrate, other in "Use MINT" mode. In "Use MINT" mode 8 tests are performed on established bitrate. In case of "TDMA" firmware teat of graduation on bitrate is not performed. Both firmware support bidirectional test.  

Figure - Performance test in case of "TDMA"

Figure - Performance test in case of "MINT"

Figure - Performance test in case of "MINT" in "Use MINT" mode

By clicking the «Run Tests»/«Stop Tests» buttons at the bottom of the page, you can start/stop the performance tests.

By clicking the «Exit Test» button, you return to the "Device Status" page.

Each row corresponds to a certain bitrate value and can be selected or deselected for participating in the performance test by marking/unmarking the corresponding check-box on the right side. By marking “Select all” check-box, all the bitrates could be selected or deselected at once.

Three more parameters are available for management: 

  • Test time” parameter - allows setting the duration (in seconds) of the test for each bitrate (5s by default).
  • Bidirectional” check-box - allows choosing between bi-directional (when checked) and unidirectional (when unchecked) performance test.
  • "Use MINT" check-box - performs 8 tests on established bitrate.
  • "Priority (0-16)" - by default, it is 16, which is lower than the data traffic that has priority 15. You can increase the test priority by setting a lower value.
  • "Packet size" - allows to set the desired packet size in bytes.
  • "Load limit" - sets a limit on the data rate at which the test runs, in Mbps.

The bitrates list on the "Performance test" tool consists of the bitrates that correspond to the channel bandwidth set on the unit (5/10/20/40MHz). To perform the tests for the bitrates related to the other channel bandwidth, you need to reconfigure the channel bandwidth (the “Channel Width” parameter in the "Radio Setting" section of the "Basic Settings" page) on both units within the tested link.

Examples given:

Antenna Alignment Tool

The "Antenna Alignment Tool" allows to visualize the signal characteristics on both sides of the link in order to make the antenna alignment process more accurate and easier.

The accuracy of the antenna alignment at the neighbor device is very important for the link quality.

Figure - Alignment test

By clicking the «Start Test»/«Stop Test» buttons at the bottom of the page, you can start/stop the alignment test.

By clicking the «Clear History» button, you delete all data stored from the moment you clicked the «Start Test» button.

By clicking the «Exit Test» button, you return to the "Device Status" page.

Once the test is started, the antenna alignment can be monitored using the graphic and text indicators. The indicators for both local and remote devices are displayed together in the same page which allows viewing the alignment process for both sides of the link.

Each side of the link (local and remote) has two similar test indicator sets, corresponding to each antenna polarization (one for Vertical polarization and another for Horizontal). This allows controlling the alignment process for each antenna polarization for the local and for the remote device simultaneously.

The text indicators are:

  • "RSSI" - indicates the power level of the received radio signal (measured in dBm), optimal parameter value -60 ... -40.
  • "CINR" - input signal level to noise + interference (measured in dB) indicator, >=28.
  • "Crosstalk" - indicates how much vertically and horizontally polarized signals influence each other, >20.
  • "Error Vector Magnitude (EVM)" - indicator of the measured input signal quality (it should be as high as possible in absolute value, the recommended level is not less than 21 dB. Some old firmware had EVM value positive, but most the firmware has negative value, so for the troubleshooting, evaluate the absolute EVM value), > 21 in absolute value.
  • "Retries" - percentage of transmit packet retries (measured in %), <10.
  • "Tx bitrate" - displays the current bitrate for the remote and local units (measured in Kbps).

Graphical indicator:

Figure - Alignment test - graphical indicator

The main indicator is the Input Signal stripe.

The height of the Input Signal stripe is measured in dB by the Input Signal Level scale. The higher the stripe is, the stronger the signal is.

The stripe may change its position along the Cross Fading scale, showing how much influence the corresponding device antenna has (for example: how much vertically and horizontally polarized signals influence each other). Higher the value of the stripe according to the Cross Fading scale (the farther stripe is from the 0 dB value), less the influence antennas have on each other.

The top of the Input Signal stripe can be located in black (Good signal) or red (Bad signal) background areas or somewhere in between them. This means the signal is good, bad or average correspondingly. When aligning the antenna, it is recommended to try achieving the stripe top to be located in the black area.

At the bottom of the Input Signal stripe may appear a special red sub-stripe. This sub-stripe indicates the presence of the packet retries and the percentage of the total number of transmitted packets.

During the alignment test, the Input Signal stripe may change its position along the Cross Fading scale and increase or decrease in height, indicating the changes in the received signal. When the top of the stripe changes its location, moving from one point on the background area to another, it leaves pink and blue marks behind, indicating the maximum and minimum measured levels of the signal at a particular point. Thus, it makes possible to observe the “history” of the signal changes.

You can clear the marks by clicking the «Clear History» button at the bottom of the page.

Main recommendations when using the “Antenna Alignment" tool:

  • It is recommended to start antenna alignment with searching the maximum signal level on a minimal possible bitrate. Afterwards, automatic MINT mechanisms will set the most appropriate bitrate when “Autobitrate” mode is enabled.
  • Input signal level (CINR) should be between 12 dB and 50 dB.
  • If signal level is more than 50 dB, it is recommended to lower the amplifier power.
  • If maximal signal level is less than 12, it is recommended to lower the channel width (for example: from 20 MHz to 10 MHz).
  • In some cases, a signal level that is less than 12 may be enough for the radio link operation. In this case, you should be guided by parameters such as the number of retries and Error Vector Magnitude. If the number of retries is low (close to “0”) and EVM is more than 21 (Input Signal stripe is green) then the radio link is most likely, operating properly.
  • Retries value should be zero or as low as possible (less than 10%).
  • The top of an Input Signal stripe should be located in the black area.
  • The signal quality should be good: EVM value should be more than 21.
  • Input signals of the two antennas of the device should have similar Cross fading values (Input Signal stripes should be symmetrically to the value of 0 dB).

ALL described recommendations are applicable to both ("Local" and "Remote") sections.

Statistics Graphs

The "Statistics Graphs" tool has been developed based on “digraphs”, which is a fast, flexible open source JavaScript charting library.

The "Statistics Graphs" tool allows you to monitor the device parameters represented in the graphical charts. The following modes are available: real-time monitoring, daily and monthly data logs display (use the dropdown menu from the top of the page to change the mode).

The system displays, by default, the daily data logs. All charts support simultaneous zoom to improve usability: the “zoom in” action in a certain region on any of the charts reflects on all other charts that are re-scaled automatically to display the data collected during the same period of time.

Critical events like link outages or frequency swaps are marked by small red balloons on the bottom of each graph. Move the mouse over each balloon for details:

Figure - Statistics graphs - balloon indicators

Working with the charts:

  • Select a chart region to zoom in
  • Hold the «Shift» button and drag the graphs to the pan
  • Double-click on any chart to reset the zoom.

The parameters that can be monitored are:

Figure - Statistics Graphs - RX/TX Ref. Level

This chart displays the measured RX (green) and TX (blue) signal levels. Red regions represent link outages. The default graph uses the CINR measurement method; however, the RSSI method can be selected from the drop-down menu.

Figure - Statistics Graphs - RX/TX Retries

This chart displays the retry percentage (it provides a quick estimation of the link quality). Similar to the previous graph, RX retries are represented by the green lines, TX retries by the blue lines and link outages by the red lines.

Figure - Statistics Graphs - RX/TX Bitrate

The Bitrate chart displays the bitrate for each of the two units in the link. These parameters indicate the link quality, too.

Figure - Statistics Graphs - RX/TX Load

The load charts display the actual link load information, either in real time or for a set period of time. The yellow lines represent the total link load, the green lines represent the RX load and the blue lines represent the TX load.

Figure - Statistics Graphs - CPU Load & unit temperature

The last chart displays the current CPU load and unit temperature (only for the units equipped with temperature sensors).

You can view the six graphs presented above into one or two columns per page by clicking the «Change Layout» button.
