What is our primary use case?
My main use case for Cisco Catalyst Switches is to enable network connectivity for many of our IT infrastructure devices. It is used to establish layer two connectivity for computing devices, switches, routers, firewalls, and other networking devices and IT peripherals.
I can give you a quick specific example of how I use Cisco Catalyst Switches in my environment: we have multiples of Cisco Catalyst Switches where we used them within our three-tier network architecture. We used to have Cisco Catalyst Switches in core, access, and distribution layer of our network topology. We used to have good network connectivity with Cisco Catalyst Switches.
What is most valuable?
The best features Cisco Catalyst Switches offer include high performance, security, reliability for enterprise-grade organizations, flexible deployment, and simplified management.
Cisco Catalyst Switches provide high performance and security features that stand out in my daily work, where they handle a high volume of traffic with low latency, making them suitable for bandwidth-intensive applications, web applications, VoIP applications, video streaming, and major data center workloads.
Cisco Catalyst Switches have positively impacted my organization by providing major network connectivity for our data center workloads and computing resources. It has improved built-in capabilities such as 802.1Q encryptions and better control over network connectivity and simplified network management using Cisco DNA Center and IOS XE automation tools to help reduce the manual work of the switches. It was actually used to provision devices in a faster manner, and we can automate devices using Cisco DNAC. The scalability of devices is much better, so whenever we have to scale our network and computing resources, it is easy to install a new device and scale our network quickly.
What needs improvement?
Cisco Catalyst Switches can be improved, especially when we have Cisco licensing models. Whenever we had to renew the license, the licensing model seems to be much more complex. It could have been more transparent and improved whenever we had to renew end-of-license and end-of-support from the OEM's perspective. In most cases, we used to integrate Cisco Catalyst Switches with Cisco DNA Center, so the subscription for Cisco DNA Center seems to be much high. It has a more costly Smart Net support contract.
I would add more about the needed improvements: the energy consumptions could have been better. Compared to other networking devices, the energy efficiency seems to be less. Also, the port compatibility could be higher for 40G ports and larger sizes of ports.
For how long have I used the solution?
I have been using Cisco Catalyst Switches for the past seven years.

What do I think about the stability of the solution?
The stability of Cisco Catalyst Switches in my environment is somewhat problematic: legacy Cisco Catalyst Switches, even though they have licenses and support, present many hardware-related issues, such as interfaces going down very repeatedly, SFP modules failing in most cases, and hardware ports becoming faulty. The devices have hardware problems, such as CPU, fan, and power modules getting faulty. In most cases, legacy devices that are more than five or six years old used to have major utilization issues. They repeatedly encountered CPU and memory utilization problems. It is very difficult to perform a firmware upgrade for Cisco Catalyst Switches because we have to manually download the software files from the portal and upload them manually. In most cases, while performing an upgrade for the old devices, we come across system down and system failure issues, making it tough to bring the VM up once again. This is a reliability issue I come across.
Cisco Catalyst Switches are stable in my environment, with no major stability issues, and mostly reliable.
What do I think about the scalability of the solution?
Cisco Catalyst Switches' scalability is manageable when we have to do the configuration manually. However, as new-age networking requires, the auto-scaling and zero-touch provisioning kind of support for Nexus switches is lacking. That kind of facility does not exist, and features could have been introduced for Cisco Catalyst Switches to improve their scalability.
How are customer service and support?
I used to contact customer support for many technical issues, and customer support seems to be good for known issues. However, they take too long to troubleshoot many unknown problems, such as CPU memory utilization issues.
Which solution did I use previously and why did I switch?
Previously, we used to have Huawei switches and Dell switches linked with Dell hypervisors and Dell EMC host. However, we did not have proper support and firmware releases and upgrades for the devices, so we moved to Cisco Catalyst Switches.
How was the initial setup?
I find the initial setup process for Cisco Catalyst Switches straightforward and simple.
What was our ROI?
I have seen a return on investment with Cisco Catalyst Switches: they attain the expected outcome of enabling network connectivity to deliver computing resources and services in a proper manner. There is not much compliance; they will do their job.
What's my experience with pricing, setup cost, and licensing?
My experience with pricing, setup costs, and licensing for Cisco Catalyst Switches indicates that I am not from the accounts or finance department, so I do not have much insight. However, I heard that the pricing seemed somewhat reasonable to the industry, but compared to other products, it is somewhat high.
Which other solutions did I evaluate?
Before choosing Cisco Catalyst Switches, I evaluated other options such as Aruba, FortiSwitches, and Huawei switches.
What other advice do I have?
The advice I would give to others looking into using Cisco Catalyst Switches is that if we have an enterprise-level network where we do not require high-throughput computational resources, and we need reliable network connectivity, we can use Cisco Catalyst Switches for better connectivity, reliable network performance, and throughput. I gave this review a rating of 7.
Which deployment model are you using for this solution?
On-premises
