After support for wireless devices was added in Nectus, specific monitoring dashboards were created to track any change that can affect the wireless users, controllers or access points. The wireless dashboards are vendor specific and this is where you can find the dashboard for Cisco wireless devices: The focus of this article is on Cisco […]
In this post we will cover some new functionality added to Nectus in latest Wireless release. The “Wireless Client Search” allows the operator to find any wireless client by its MAC, IP address or Username. The client search is located under main menu “Tools”: In the menu, you have an option to search for a […]
In this post, we will cover the wireless heat maps and how they are created in Nectus. A heat map will allow to visualize the state of the wireless coverage and help to take decision in order to improve the coverage. Using the information from APs along with a map of physical location, you can […]

Nectus goes wireless. Starting from version 1.2.24 we added support for Cisco Wireless. Powerful dashboards and RSSI heatmaps now available to all Nectus customers. Download your copy of Nectus
One of the key features of Nectus is ability receive SNMP traps. This allows the operator to quickly detect physical (links failures, flaps) or logical (adjacencies failures, flaps) changes in the network followed by restoration procedures or root cause analysis. Let’s see how does it work on example of this Layer 2 diagram: The SNMP […]
Nectus can monitor OpenFlow capable devices in the same way as the non-OpenFlow devices. In this article we will show how Nectus can discover and monitor switches that are SDN OpenFlow ready. We will use following sample topology for demonstration with Floodlight OpenFlow controller and three OpenFlow switches:
Under the Tools menu, there are quite a few tools that can help the operator to understand better the network, to perform troubleshooting and to gather information from devices. These are the options:
This post will cover the SysLog server functionality of Nectus network monitoring software. As with any modern network monitoring software Nectus has the ability to receive and store the syslog messages from routers, switches or servers. Syslog messages can be accessed from Top menu “Logs”:

Meltdown and Spectre bugs in simple words. All modern processors have very important feature called “Speculative Execution” where CPU tries to predict all possible operations that might be required to be executed next and actually executing those without knowing for sure which one will be the next. Those guesses are called Speculative Branches. By the […]
One of the latest features that was added this week is “Routing Table” view in device context menu.
PowerPoint Nectus features presentation as of January 2018 Nectus Overview
Trust me. CLI is not going anywhere. CLI is the only way to troubleshoot SDN. There will be plenty of new CLI commands to “show” flow tables logic, operation and debug communications between data plane and controller. I would say importance of CLI is even greater in SDN as you now has to observe operation […]
So.. you upgraded your network from legacy dedicated hardware to OpenFlow based SDN, laid off all of your network engineers who know CLI and ask yourself a question: How do I monitor my SDN now? How do I pull a power supply status or CPU temperature? How to read TCAM utilization level? How to see an […]
This post will cover how Nectus can dynamically build topologies and how you can check various performance statistics. Nectus gives the possibility to build automatically L2 and L3 topologies based on the discovered devices. Additionally, it allows the administrator to create custom topologies by dragging on the map the devices that are required to be […]
This post will cover the configuration backup and change tracking features available in Nectus. Nectus provides the ability to back up the configuration of the devices discovered, on a scheduled basis and manually. Nectus comes with some default settings regarding the configuration backup and for others administrator input is required. This is the configuration backup […]
