Likelihood to Recommend

Cisco IOS

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.

Cisco NX-OS

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.

Cisco NX-OS

  • Stability of the software (in the early days).

  • The command syntax is sometimes just that little bit different from iOS, causing issues for automation, scripting, etc.

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.

Alternatives Considered

Cisco IOS

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.

We studied the solutions from both vendors but we went for Cisco because it's powerful out of the box and has great support. It's also easy to find knowledge and support communities, and we already had a relationship with Cisco.

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.

  • It is serving the purpose from last few years.
  • Need to spend multiple manpower cycles to do the reload/code upgrades.
