The "Device Status" page is displayed by default after the authentication step. It displays the main parameters of the unit in real-time.
You can set the "Auto Refresh" option to refresh the statistics automatically. Refresh frequency can be set by the "Auto Refresh Time" parameter. The minimal possible value is “0” seconds and it updates the information instantly. These options are available in the bottom-left side of the "Device Status" screen:
The device statistics can also be refreshed manually by clicking the «Refresh» button.
The "Device Status" page has the following sections:
"CPU load" - displays the load percentage of the CPU
"Memory load":
Memory (the data stored in volatile memory are valid only during the current session, until the system reset) displays in real-time the total memory available and the used memory by the running processes
Flash memory (non-volatile memory) displays in real-time the total memory available and the used memory by the operation system and configuration files
"Interface Statistics" - displays the main parameters of all configured interfaces (physical and logical)
"Wireless Links Statistics" - displays the main parameters of all wireless connections between the device and the neighbor devices
"Switch Statistics" - displays counters of the frames which have been switched or dropped.

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 "Auto Refresh" option is active by default and refreshes the statistics automatically. You can disable the auto refresh.
The "Modulation Statistics" tool displays the information about modulation types, such as receive and transmit statistics for different coding scheme.
Please note that lower modulation is used for service traffic transmission, therefore, if such traffic prevails in the network, the counter growth for low modulations is normal.
By clicking the «Close» button, you return to the "Device Status" page.
By clicking the «Reset» button, you clear all counters displayed in the page.
The "Auto Refresh" option is active by default and refreshes the statistics automatically. You can disable the auto refresh.
The "Errors/Drops Statistics/SNR/EVM" window displays the number of errors, retries and droped packets during transmission for each link. This tool provides information about the SNR level for each polarization of the remote and local devices, as well as rates of lost and late delivery acknowledgments.
In addition, this section displays the estimated throughput per subscriber in Mbps. The lower values show the guaranteed throughput in the worst case scenario when all subscribers are actively transmitting. The upper values display the throughput in the best scenario, when data is transmitted only by the selected subscriber.
The EVM value is measured not at the operation modulation, but at the lowest possible. In case the misoctl option is enabled and VBR is disabled on Slave, the lowest possible modulation uses a single data stream. If misoctl is turned off or VBR is turned on, both channels will be used for transmission, and the EVM parameter values will be displayed for each modulation.

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 Evolution 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 Weighted Fair Queuing scheduling algorithms. 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.

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 rf6.0" section:
Five options are available: "Performance Tests", "Antenna Alignment Tool", "Statistics Graphs", "Remote Commands" and "Link Restart".
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 current bitrate.
NOTE
All results are given in kilobits per second and retries levels are shown as a red chart.
Performance tests contains of 8 tests performed on established bitrate, test can be performed in one direction or bidirectionally.
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.
"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 "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.
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.
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.
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.
"Tx bitrate" - displays the current bitrate for the remote and local units (measured in Kbps).
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.
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.
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. The link down periods are marked with red fields. Move the mouse over each balloon for details:
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:
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.
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.
