Cisco NX-OS Reviews

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.

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.

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.

Cisco NX-OS allows us to build and improve a stable data center network. It prevents downtime. Many times we faced some network issues and spent long hours trying to find the source of them. Cisco NX-OS helps us resolve them quickly. What is more, with Cisco NX-OS, our data center network is more secure.

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.

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.

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.

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.

Cisco NX-OS is really best suited for data centers, and/or locations where you host a compute stack or servers. Most of the advantages and features that NX-OS offers are really useful in that area. The platform is less suited in smaller environments or to be used as a regular core or access switch.

Scalability : NX-OS has a lot of scalability features; not only allows it to virtualize hardware, there are also a lot of hardware models and features available to be able to scale it from a smaller server deployment scenario to a large datacenter. We particularly use the virtualization a lot to create distinct DC environment that we connect through external links, and we also use a lot of the Field Externders (FEX's) to foresee connectivity throughout our datacenter without having to buy expensive hardware for each row or area.
