"Events" block on the control panel

This block is located on the control panel in the top right corner and looks as follows:

The block shows number and priorities of active events. Separation of event priorities is performed by colors:

• Blue — WARNING events;
• Yellow — MINOR;
• Orange — MAJOR;
• Red —ALARM.

Events on this panel will be displayed for the selected node in the EMS tree. When selecting the root device (EMS), information about all devices present in the tree will be displayed, as well as system-wide events, including events of the EMS server itself. Events are added to the list based on SNMP trap messages received from devices.

Clicking on a block in the settings field opens a list of active alerts.

Double-clicking on the selected event to reveal the details of the alert.

Control (manual closing) of selected events is performed via the context menu by right-clicking on the selected event.

OLT status monitoring

Device summary

When a device is selected in the object tree and the cursor is moved over it, brief information about the current state of the device is displayed in the form of a tooltip.

You can also use the context menu to get this information in a separate window: right-click on the row with the device name and go to the "Device Summary" section.

For more information regarding OLT monitoring, please refer to the "Monitoring" menu.

"Monitoring" menu

"Active alerts" tab

The tab contains the list of current alerts and emergency events of the device. Events in this list are created when receiving alert traps from devices or when internal periodic system services (e.g. availability control, temperature control) are running. A copy of each event, when it occurs, is saved to the event log of a given device. In case of automatic normalization (for example, when a normalizing trap is received or an exchange channel is restored), the event is deleted from the list of active events, but remains in the log. Both alert and normalization messages are recorded in the log.

"Common" tab

The tab displays general data received from the device. The information is available in read-only mode.

"Events log" tab

The tab contains the list of events, information about which was received from the device.

"Syslog" tab

This tab displays the system log entries of the device. The information is available in read-only mode.
SYSLOG is a protocol designed to send messages about events occurring in the system. The EMS can act as a SYSLOG server and receive log messages from devices. In this example, sending SYSLOG messages is not configured, so there is no information in the tab.

"ICMP statistics" tab

This tab displays a time chart of the delay in receiving responses to ICMP requests (ping). The EMS system independently performs periodic ICMP polling of devices. Red dots on the chart indicate errors in receiving a response to ICMP requests.

"SNMP statistics" tab

This tab displays a time chart of the delay in receiving responses to SNMP requests from the management system. The EMS system independently performs periodic SNMP polling of devices. Red dots on the chart indicate errors in receiving a response to SNMP requests.

"OLT" tab

This tab provides operational monitoring of OLT ports status, as well as the status and speed of fans.

Indication of fan states:
— operational.
 — disabled by the network administrator or is in an emergency state.

Port indication:
— the current state of the interface is UP — operational.
— the current state of the interface is DOWN — port is not active/not connected.
— the current state of the port is unknown — port is not active/not connected or disabled by the network administrator.

The port status buttons are active elements, when clicked, the interface information window opens, where it is also possible to change the administrative state of the port.

"Power" tab

The section contains data on the current status of the power supplies connected to the OLT: module name, power supply type and primary voltage status.

"Temperature" tab

In this tab, graphical statistics of change in readings of temperature sensors installed inside the modules is available. The graph visually displays the dependence of the measured parameter on time. The graph type (diagram or linear), data type (average or maximum), as well as the displayed time period (from the last two hours to a week) can be customized in the corresponding drop-down fields below the graph.

"PPPoE session", "DHCP session" tabs

The tabs contain data about the currently active PPPoE and DHCP sessions. The information is available in read-only mode and only when PPPoE or DHCP snooping is enabled.

The "PPPoE sessions" tab contains a table with the fields PON serial, client MAC, Session ID, ONT ID, Channel, Duration, Blocking.

The "DHCP Sessions" tab contains a table with the fields PON serial, Channel, ONT ID, Service ID, Client IP, client MAC, VLAN ID, GEM Port, Lifetime.

"MAC table" tab

This tab monitors the MAC address table of all ONTs connected to PON or Switch ports (front-port, port-channel). Using the "Pon/Switch" drop-down list, it is possible to select a certain type of ports for which the information will be displayed.

"PON channels" tab

In this tab, the SFP modules of the device are managed and monitored. The upper panel of this tab provides quick actions with these interfaces — enabling, disabling, reconfiguration.

This tab contains a table with the list of PON interfaces. The number of PON interfaces depends on the OLT model. This table provides information about the state of SFP modules connected to the PON port, their vendor and model, information about the number of ONTs connected per channel and SFP physical parameters: tx power, temperature, voltage, offset current.

"ONT license" tab

This tab provides information about the license installed on the OLT for connecting third-party ONTs. The information is available for reading only. License installation to OLT is possible via CLI.

"Operations log" tab

This tab provides detailed information about the actions performed from the EMS GUI on this OLT.

"Firmware upgrade" menu

Operation with OLT, ONT software (except for commands of selective ONT software update) is carried out in this section. The section includes three tabs: "OLT firmware", "ONT FW Autoupdate", "ONT firmware files".

"OLT firmware" tab

In this tab you can change the active firmware image, reboot the OLT to apply the new firmware version, as well as upload a new firmware file to the OLT for further update.

"ONT FW Autoupdate" tab

In this tab the automatic ONT update can be configured. Created rules are displayed on the page. The rules can be created, edited and deleted. For a more detailed description of the feature, refer to a user manual.

"ONT firmware files" tab

This tab is used to manage the firmware images for the user terminals stored on the OLT. Here, the ONT firmware can be downloaded or deleted from the OLT.

Operations with OLT

The main operations available for the current object (LTX) in the device tree are placed in the context menu of the object (opened by right-clicking on the object). The OLT operations available in this menu are shown below:

ONT status monitoring

"ONT list" menu

This section displays information about all ONTs registered on the device and physically connected to the ONT's PON channels, as well as their characteristics.

Double left click on the selected ONT to open the window for editing its configuration.

Right-click the selected ONT to open a context menu with an option to request detailed information about the ONT and possible commands.
