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 […]
New version 3.2 of our famous Smiley IP Scanner application has been released. It features improved user interface and faster more reliable operation. Supports all modern Windows OS. Scans for live IPs within specified range and checks for open TCP ports for each live IP address. Scans for open TCP ports even if IP address […]
When selecting specs for Nectus VM that will be used for Netflow collection storage we recommend following specifications: RAM: Amount of RAM has to be not less that Netflow DB size growth in one week. Example: Your Netflow storage grows by 10GB every day. Recommended RAM amount is 70GB CPU: Number of logical cores has […]
Very often I am invited to review new network related software products from other companies as an expert in workflow and UI optimization. I always start with asking who designed the User Interface and I see that in many cases user interface designer and a coder is the same person and that where all the […]
One of the key features of Nectus is ability to get instant SmartNet validation for any piece of Cisco hardware you have. SmartNet validation is implemented via “Cisco Smart API” interface available for selected customers with SNTC (SmartNet Total Care) or Partners with PSS (Partner Support Service) agreements. Nectus SmartNet validation requires API account (Client […]
One of the limitations of VIRL that it does not provide real-time visual Up-Down status for Interfaces in your VIRL topology. Pairing VIRL with Nectus give you best of both worlds. To allow Nectus to monitor your VIRL topology enable and configure SNMP on your VIRL routers and ensure L3 reachibility between your VIRL subnets […]
