The supported device discovery protocols include SNMP, Ping, etc. During the discovery process, switch devices can be automatically searched, and the device type and manufacturer can be identified. model, which generates a panel diagram of the device. And it can search out the board, port, fan, status light, CPU, and memory of the device for monitoring. At the same time, it can also discover the link relationship between devices.
3.2. Network topology display
SugarNMS manages the entire switch network based on a graphical interface that is divided by area, region, and hierarchy across device types. The device link relationship is shown in detail in each management area or level. The latest status information of the device is displayed in real time with device icons of different colors in the topology.
Divide management areas by aggregation layer
access layer ring
3.3. Link Discovery
The software supports LLDP, CDP, ICMP, ARP technology, neighbor routing, port forwarding table, spanning tree protocol and other physical topology discovery technologies. Links between devices can be automatically searched and displayed, or links can be maintained manually. The system can display multiple performance data, faults, and operating status of the link in real time. Real-time traffic, bandwidth, faults, etc. on the link are displayed realistically through the graphical interface, and the link status is visually distinguished through different colors.
3.4. Industrial Ring Network
The unique industrial ring network identification technology of the software can automatically search and display the industrial ring network in the network. And can identify the backup link, the blocking point, realize the unique function of the industrial switch network.
3.5. Switch panel diagram
SugarNMS supports the management of switch devices in the form of a real panel diagram of the device, and displays the latest status of resources such as ports, fans, power supplies, and CPUs in real time in the device panel diagram. It also supports editing the device logic panel diagram to display device resources.
3.7. Fault management
- Fault collection: SugarNMS has an active fault monitoring function, which can summarize the scattered status information into the current working status from numerous events and statuses, and generate alarms.
- Fault optimization: including event filtering mechanism, fault event reporting mechanism, fault event presentation filtering, fault event storage filtering, fault event confirmation and other processing mechanisms to effectively avoid false positives and false negatives.
- Fault location: It can realize fast fault location, locate the source equipment of the fault in one step, handle the fault in time, and effectively prevent the fault from happening.
- Fault handling: By setting the fault valve value, the notification mechanism can be triggered in advance before the fault really comes. And support three-level gradual warning. After the fault disappears, the system can automatically detect the previous fault and automatically clear the alarm.
- Fault notification: The fault can be notified through the interface color, alarm list, sound, SMS, Email, etc. The alarm can be traced up step by step, and the fault display can be organized according to the management habits from the global -> network -> equipment -> equipment resources.
3.8. Performance Management
The software can collect performance data such as switch port traffic, bandwidth, packet loss rate, CPU load, memory usage, and system response time in real time. Display performance indicators through graphs, trend graphs, etc. You can view changes in performance indicators by day, week, month, or any time period.
3.9. Device Backup and Upgrade
SugarNMS can backup/restore switch device configuration, and support device software upgrade function.
- Configuration file backup/restoration: Supports backup/restoration of single device configuration file, and backup/restoration of batch device configuration files (timed and timely). The network management platform comes with an FTP server, and the device automatically starts the FTP Client to transfer files and perform backup/restore functions.
- Device software upgrade: Supports device software upgrades for single devices and batches of devices. Batch upgrades support two upgrade methods: regular upgrade and timely upgrade. The network management platform issues upgrade commands through SNMP to perform device software upgrade operations.
3.10. Device parameter view
The switch parameter viewing function provided by the network management system is as follows:
3.11. Statistical report
SugarNMS network management has a powerful report management function, which can generate real-time and historical reports based on days, weeks, months and any starting and ending time periods.
