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 […]
Here is the list of NetFlow reports currently supported by Nectus Top Applications Top Protocols Top Source IP Top Destination IP Top Source + Destination IP pairs Top Source BGP AS Top Destination BGP AS Top Source + Destination BGP Pairs
Nectus beats Solarwinds in pretty much any aspect: Speed, Usability, Size, Installation Time, Support. We optimize every little function or procedure to perfection and re-write it with Assembler language if it is not good enough. We develop custom stress-testing tools (such as Netflow Generator ) so we can push the Nectus KPI limits higher. Our […]
When it comes to Network Discovery we are absolute market leaders and can determine router model by the sound of its Fan. Just kidding.. But here is how we actually do it. Let say IP address 10.20.45.1 is alive and we need to determine what type of device this is. Step 1: Perform SNMP Get operation […]
In this article we will see some of the features of Nectus that can enhance the Virtual Internet Routing Lab (VIRL) experience. VIRL is Cisco’s network simulation platform where you can run Cisco OS (IOS, IOS XE, IOS XR, NX-OS, ASA) virtual machines and other third party virtual machines (this includes Linux servers, traffic generators and […]
On every Nectus installation that we conducted I noticed that on average each company has around 10% of network devices that are configured with well-known snmp v2 community strings: public/private. This is as bad as using “cisco/cisco” as your SSH credentials. That is major security loophole as even read-only string “public” gives possible attacker complete view […]
To keep a good track of your network it is necessary to have a network diagram of your topology so you can know for sure where each device is located, where it is connected and in case there is a failure in your network it is easier to find the devices affected. You can create […]
Well, if you are reading this article you probably know what NetFlow is and how much data it can generate. 100GB of NetFlow records per day is not something totally unusual in NetFlow business. We tried most of the commercial and open-source existing database engines like Microsoft SQL Server, MongoDB, PostegreSQL, MySQL or even Oracle […]
Most of the enterprise grade monitoring tools allow predefined thresholds to be set for specific monitoring parameters such as interface utilization, RAM utilization or percentage of free TCAM available on switches. When a specific metric exceeds a predefined threshold you will receive an email alert, text message, or… a phone call from your manager. Likely […]
Next Generation of Network Discovery and Monitoring Tools There are many reasons why your network needs to be monitored. It is essential to any network administrator to keep track of the network’s performance and usage in real time and to detect failures, slowness or any other threat that could be affecting the network. Every device […]
We will be adding IPAM (IP Address Management) module to the Nectus NMS starting from January 2018. No special licensing will be required and it will be immediately available to all current Nectus users free of charge. Support for IPv4 and IPv6 address space management, API interface for third party integration and many more cool […]
Implementing company-wide standards for interface description strings in routers or switches should be a top priority for all network engineers. Well defined and structured description strings helps with automation for the most tedious and boring manual steps associated with deployment, configuration, monitoring and decommission of any network connections. Network interface descriptions should include some of […]
We are proud to announce that our next Nectus release will include the most powerful and feature rich telco circuit management platform available on the market today. Nectus CircuitDB provides a central repository of all of your circuit contracts and provide reminders well before contract expiration times so you can renegotiate better prices with your telco […]
CircuitDB gives ability to track of all the telco circuits (Internet, MPLS, T1 etc), carrier contracts, cabinet/rack/patch panel information. Support for configurable email alerts on approaching circuit contract renewal dates, integration with real time circuit monitoring. Never pay for circuits that not being used and many more cool features.
Here is the most complete list of features available for Nectus customers
One of the biggest challenges with SNMP v3 deployments in diverse environments is a lack of consensus among hardware manufactures on what set of Privacy Ciphers has to be supported/included in standard SNMP v3 stack. Even Cisco was unable to unify list of supported v3 Ciphers in different product lines (ASA vs NX-OS vs IOS-XR). Partially […]
We have had several customers (well, not yet customers) who are in network consulting business and who keep using Nectus as part of their Network Discovery service offering portfolio. They don’t buy the software , but only use it within the 60 days that we allow for free trial. We are very happy to see that […]
