Well suited for building management networks across the organization as it has been reliable without much downtime. Since it has great switching qualities, it suites well for data center and end-user connectivity using access switches. It might not be the best for routing, as other XOR software has proven to be superior for routing.

NX-OS has many similarities with the traditional IOS which is quite beneficial when it comes to configuration and learning. As a native Linux system, there are a lot of tools and features that can be enabled for any use case.

Our switches running NX-OS have provided solid consistent throughput. We haven't had any issues with it not being able to handle what we threw at it. The latency is extremely low. It also has multiple management options that we hope to pursue in the future.

Cisco support never fails me. In terms of timely response, no one is on par with them. They really value the impact of having technical issues and potential business stoppage. Also, their support staff are well equipped with knowledge and skills and easily resolve the most common incidents. Most of the time, we can resolve an issue by just calling them once.

We have found other Cisco software to be filled with added functionalities as compared to iOS. New NCS software has certain programmability features that are advantageous to legacy iOS software but are more complex to use for some users. Hence, we still have most areas of the network that functions using iOS software.

Up to now, we haven't had a major ground-shaking attack on our networks but we take no chances by using NX-OS alongside a SIEM. All endpoints and workloads are secure so I would say we have plenty of trust in their security model.
