Cisco NX-OS

Cisco NX-OS is probably the best way to build a reliable data center network to prevent downtimes. While other solutions provide only the basic SRv6 architectures for networks, Cisco NX-OS goes an extra mile to help enable Data Center interconnection (DCI) with your WAN to tone down on the network complexity. NX-OS from Cisco would also bring in more flexibility on how you manage your networks and scale more easily.

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.

Ease of use and learning is easier. The documentation for CIsco NX-OS is very good as it was in the market for many years. There are very good case scenarios and wiki pages written by well-experienced experts. These pages will provide quick resolution techniques for the most occurring frequent problems and misconfiguration issues.

Security is top-notch in this NX-OS switch. This may not be as good as a dedicated firewall but for a switch, this one provides good security features within it.

This easy solution can be a great help for the big companies on easy multiple data processing and effective networking solutions for the various departments and also generating the real-time data reports with Cisco NX-OS is excellent. For the new users, it takes no time to become a pro on full manipulation of the features and offer the best and quality management services.

Highly secure networking environment and effective data collection platform and the best services Automation tool. Through this Cisco platform, data protection is on top and all the operations are managed securely from this single network performance management system with a secure management environment and also its data analytics production is excellent.

Cisco NX-OS offers excellent capabilities for performance acceleration and easy to manage multiple business network operations and a very secure environment that provides multiple different features and is very easy to get started. Cisco NX-OS offers capabilities on easy use of API which allows effective interaction with the OS and configuration is very easy.

Excellent security is offered by the network operating system and the best power with effective scalability. Easy on security configuration and setting. Performance is also the best and very cost-effective and the data management capabilities are a very high and reliable tool that gathers all the network operations control in one room.

The Cisco Nexus and [Cisco] NX-OS are really well designed for datacenter purposes. It's doing VDC so you can split a single physical box into multiple logical (in cases of multi-customer environments, for instance). The FEX Nexus 2K [is] really easy to configure and to be associated with Nexus 5K and doing high-performance work.

We didn't increase the security too much. At least we enable the default features, but I know that we can do better than that on this topic, but [there's a] lack of time.

The software NX-OS is a very good IOS developed by Cisco. It is very easy to configure and administrate these NX-OS devices. A lot of improved and high availability HA on the NX-OS. A lot of features and added advantages while we use the devices which have NX-OS. overall we are very happy with the product and we recommend it to all to start using.

the product is safe to use and the IOS is upgraded by ciso whenever there is an vulnerability found out. we are see this tool as one of the best tool and it also support security features like port and ACL etc. the NX-os have even the capability of firewall. we will need to enable the module and we are good to use it . the firewall feature does a good job by filter the unwanted traffic.

Cisco NX-OS is designed to run on data centre switches, and for me the key benefit is the ability to merge Ethernet and fire channel management into a single switch hence reducing cabling and management. However we don't require fibre channel at present so these are just being used for the fact they offer 10GbE on every port, which is still a useful feature in the data centre core.
Given we don't use the fibre channel features, having to learn the difference in commands from iOS is a little frustrating at times.

Security is something I know Cisco take seriously and there are many security features across all their devices. I don't think features like zero-trust are enabled by default though, so it does require reading the relevant guide and applying commands that suit your environment which can mean the implementation is not always as robust as intended.

Cisco NX-OS is an excellent option for a core switch if you need solid resilience. It provides a solid level of security for a core switch as well. If you aren't going to be running multiple connections from wiring closets or VM infrastructure then a less pricey option would be recommended unless you need the port bandwidth. Personally I think the VPC functionality within NX-OS is relatively easy to use and works well.

This obviously wouldn't replace a firewall, but for a core switch it supports plenty of security features that you may not see in other platforms. I would recommend NX-OS if you are looking for a secure core switch.

Due to the separation of features and the ability to enable each feature when you need it, using Cisco NX-OS decreases the processing on the switch and the memory use as well. The switches become more powerful and can handle much more traffic and sessions than normal switches. The ease of commands makes it simple to use.

One of the scenarios is to use in the DC network in the unified fabric, where automation plays a significant role. As NX-OS supports programming languages build in, the automation tasks can be run easily. It is also possible to integrate the DC network with DevOps tools. It is less appropriate to use it in the access switches in the DC.

Documentation and support is always very high quality.

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.

We use Nexus 3Ks for switching in data centers where we host with 1G and uplink is 10G. This may not be appropriate where we need more host port throughput. NX-OS has a very simple design and CLI to use, but we need to have either reloads or code upgrades to fix the memory leak issues.

It is well suited if you have full-blown Cisco solution deployments across the globe because of its compatibility with other Cisco species or technologies. Also, it has a lot of innovative functionalities that you will not find on other network OS from efficiency to security compliance to routing and management effectiveness. If you are looking for an all-purpose OS, go for it, but if you are just requiring specific services that can be found on other network OS, go for that because Cisco is not cheap.

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.

Cisco NXOS is well-suited to our customers in financial institutions like banks and insurance companies. It gives high availability and supports a high amount of traffic, that's why it is well suited to be the core of banking technology. It is less appropriate for small and medium enterprises because of its cost.

I gave it an 8 because there are commands that are not known on NX-OS. Also, there are some software bugs found on NXOS.
