Devices
NEXT allows the network engineers to monitor the status of the wireless devices and to manage their configurations.
Devices review
The section includes two key areas:
Devices list - devices and their groups that are in the user's visibility area.
Side area for detailed information.
The list of devices is displayed in a table with the following columns:
Device - the device name.
Status - current device status.
Family - family to which this device belongs.
Serial number - unique serial number assigned to device at the production stage.
IP address - device's IP addresses list.
Device profile
Each device is presented by its profile contains the whole information about device. There are following section in profile:
Status - device operation parameters.
Maintenance - management tools: firmware, configurations etc.
CLI - device management via command line interface.
The "Status" section consists of several parts:
The status of device and its wireless link.
Network interfaces statistics.
General information.
There is special section includes both the current and remote device. This section presents characteristics of wireless link in downstream and upstream. For local and remote devices, there is the ability to switch to its web interface or to manage via the command line.
Network infrastructure requirements
Management functionality requires network connectivity from wireless devices to the monitoring system port 2121/TCP, please check your firewall rules.
Management
Management tools are presented in the "Maintenance" section of device's profile.
Configuration
The configuration is automatically loaded for each device added to NEXT. If the device's configuration has been changed, it will be reloaded, but the previous configuration won't be deleted. Thus, the monitoring system always stores both the current device configuration and its previous versions.
NOTE
Configuration and software management functions are available only for devices monitored via SNMP v3.
To view the device configurations list, click on the "Manage" button in the "Configuration" row:
The list of configurations includes the entire configuration history, displayed as a table with the following columns:
Status - current configuration status, the following values are possible:
Draft - draft configuration stored in the monitoring system and not applied on the device.
Success - the configuration was successfully downloaded from the device or applied on it.
Error - the applying of the configuration on the device has failed.
Source - configuration source, the following values are possible:
EMS - configuration applied using NEXT.
Device - configuration received from the device. Configuration changes were made directly on the device, the monitoring system has detected it and downloaded the updated configuration.
Version from - configuration date and time:
The date and time of its uploading to the monitoring system.
For the draft, the date and time of the last change.
Select any configuration to view it:
You can compare the two configurations to see how they differ. To do this, in the "Compare" list, select any other configuration.
To highlight changes in the comparison mode, click on the "Show the difference" button.
Configuration changing
Changing the device's configuration includes the following steps:
Select the configuration version.
Edit selected configuration.
Create job - set a task for applying the configuration on the device.
Apply the configuration — the configuration is applied on the device.
Configuration editing
Click "Edit" button in the selected configuration. A draft will be created, with the content identical to the previously selected configuration. Each device may have only one configuration draft. If you create a new draft the previous will be rewritten.
After editing, you can save a draft without applying it on the device, or create a job to apply it. You may apply any configuration version without editing by clicking "Create job" button.
Job creation
When you are ready to apply configuration draft please click "Create job" button.
In the menu, you can schedule the time for applying the configuration, the following options are available:
Create job at a required date and time.
Create job for the current time.
NOTE
In order to perform the jobs execution at a required time, it is necessary to set date and time on the virtual machine where NEXT is installed. Time settings can not be made in the monitoring system.
Applying the configuration
At the set time, the configuration will be downloaded to the device. After successful validation, the configuration will be applied and the device will reboot.
NOTE
Configuration applying procedure eliminates the risk of loss of communication with the device due to configuration errors or other failures. For details, see the "Description and operational principles" article.
After rebooting the device, NEXT will re-poll it and perform a configuration check. If it was applied correctly, then the job will be marked as completed successfully. Otherwise, the job will fail.
Firmware
The monitoring system provides the ability to update the software, both on one and on a group of devices.
Upload firmware files
To update the firmware, it must be previously uploaded into a special storage of the monitoring system. In order to do this, go to the "Management" section and click the "Firmware" button.
Each file in the repository has the following fields:
Version - the firmware version.
Platform - the hardware platform for which the firmware is intended. The monitoring system will allow to create an update task using only those files that are suitable for the device selected.
Type - the firmware type, MINT or TDMA.
Source - firmware files can be uploaded to the repository either manually or automatically from the update center (not available at the moment). Here will be displayed the source of the file.
Build date - date when the firmware file was built.
Comment - the monitoring system administrators can leave comments to each file.
Firmware update
The firmware update is performed via a special update job. In order to do this, go to the "Maintenance" section of the device card. In the "Firmware" line click the "Manage" button. This will open a list of firmware files suitable for this device.
Select the firmware version to be applied to the device, then click the "Create job" button. Same to the configuration update jobs, you can run the update immediately or schedule it for a later time.
Command execution
The monitoring system allows to manage the device using the command line. The command line is available in the "CLI" subsection of the device status section.
To manage the device from the monitoring system, it must be provisioned, see "System configuration - Provisioning" article.
