Working with SNMP Traps in Nectus NMS

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 […]

Meltdown and Spectre bugs in simple words.

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 […]

Will SDN kill CLI?

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 […]

Monitoring of OpenFlow SDN networks

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 […]

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 […]
