Cisco Catalyst Center provides an intent-based platform for managing enterprise networks across campus, branch, and edge environments. It combines automation, analytics, and assurance to streamline IT operations, improve security posture, and reduce manual tasks. With integratedAI/ML-driven insights, policy-based controls, and end-to-end visibility across wired and wireless infrastructures, Catalyst Center empowers IT teams toproactively detect issues, enforce compliance, and accelerate…
I feel that Cisco ACI is quite good at different architecture designs. You can have it as just a straight layer two network. You can have it like we have with a vast layer three network and I think just for the layer three network it has easen up the use. I think the use cases for layer three networking is better for ACI. If you just want to do the layer two, you can still use Cisco Nexus and so on and that should be almost simpler in some way.
Security with identity-based access control and segmentation via integration with Cisco ISE, supporting zero-trust architectures. Centralized Management for a large campus environment with centralized management of wired and wireless equipment. Automation of tasks like: provisioning, configuration, and software upgrade, reducing manual effort of those tasks. It could be improved to Multi-Vendor Support.
So with the old one, we've had a secure zone, core zone, so we have special hardware specific for those zones, so security zones in our data center. This allows us to basically have the spine leaf and we could put any ports in any zone. So it allows a lot more, I'd say efficient use of equipment, being able to plug in things to whatever, and then program it to how you want it to work on.
I really like the assurance. I like that I can go through and find problems on the network that could be a mismatch VLAN between two interfaces, port errors, like physical errors that we otherwise probably would need to wait for a customer to complain or we have that we can see that ahead of time and be proactive and say, Hey, I'm noticing that this port is having some errors on it. We might want to check that out ahead of time before it becomes an issue. So that's really useful. And then also being able to configure the network. I think that the programmability part of it, I think I have, I've been having some struggle with that initially, just having to apply. So I have my script, my template that I want to deploy, but in order to deploy it, I have to apply it to a template or a profile and then I have to assign that profile to a group of switches that I want to program. I think it gets a little bit messy and a little bit convoluted, but other than that, I mean it's really helpful. It does automate right now, I think it seems a little convoluted with the process.
I think something I've just went to a session with hyper fabric and the ideas that hyper fabric has. Keep it really simple because Cisco ACI is a complex system and adopt some of the ideas behind hyper fabric, bring it to ACI that will be really beneficial. So as I said, automation is a great thing, but it's still, you need to have the background and the really complex stuff that happens behind the scenes to leverage the value of that solution. And by adding more simplicity to it, I think that will be a great thing. And also integrating with other applications in terms of the automation.
The one thing that we had to get used to was really breaking down our wireless. We integrated our 9800 controllers into it, and the breakdown of our tags being floor specific and not just being campus specific was a challenge for us. And so we had to create all new tags and it wasn't necessarily a problem, it just required a little bit redesign on our wireless. And so it would've been nice for us to be able to assign a tag to an entire campus versus a floor, but that's a small complaint.
Cisco ACI is doing exactly what was intended for it to do, that is support our next generation data centre, improve security, and increase resiliency. Migrating to another platform would be a waste of time, resource and energy, which could be better spent migrating more legacy applications into the Cisco ACI fabric.
I think new products are often "half-baked" or over hyped when they release, as was the case with DNAC. We were well ahead of the curve in acquiring it. But as it has matured it is now a fantastic addition to our infrastructure. I think we are easing into a stage where it is hard to envision a large organization NOT having Catalyst Center in place. If for nothing outside of the mapping and troubleshooting aspects; using it as a "source of truth".
Cisco ACI has changed the traditional data center model into a new era of automation and agility. The product was considerably easy to deploy met all the expectations. In terms of usability, ACI provides a unified interface for managing the whole infrastructure in one place which is the main benefit for users (admins)
Cisco DNA Center is going to help us in security, simplicity and ease of administration. Cisco DNA Center is complete management and control platform that simplifies and streamlines network operations. Cisco DNA Center offers a single dashboard for every core function in your network. With this platform, IT can become more nimble and respond to changes and challenges faster and more intelligently.
It allways works. If there are problems with links going down by accident (say someone accidentally unpatches something they shouldn't have), we rarely miss more then one packet over the link. Also, using VPCs we are able to upgrade the software on the switches without the attached EPs ever noticing.
I do not give it 10 because the platform evolves more and more every day in the data traffic of the datacenter. But the implementations that they carry out for different clients of the platform are very happy with the result of the same over time. Another point that you notice about the platform, despite its good performance, is the low use of energy used by this 24x7 on, it is a good fact to take into account for our environment.
Cisco provides users and partners with a multitude of data for you to consume. I think that the stuff in the public domain goes a long way to assisting you find any answers you may need, plus insights and information from areas such as DevNet provide you with access to more than just the traditional release notes and the like
El soporte de CISCO DNA Center es muy bueno, responden a mis dudas pero no he tenido oportunidad de reportar un incidente o determinar un tiempo de respuesta critico. The support of CISCO DNA Center is very good, they answer my questions, but I have not had the opportunity to report an incident or determine a critical response time.
The Cisco ACI training provided by Cisco was in depth, covered all of our requirements, and allowed us to implement and maintain the platform without issues.
It was informative, but the labs were not available long enough for us to get intimately familiar with CCNA before it was closed. The course instructor was well informed and got us as close to ready as she could.
Being involved in the implmentation gives you more overview on how things are supposed to be working and communicating, you can easily performce troubleshooting and understanding the troubleshooting scenario
I've used the Cisco Wireless LAN Controller 9800. I was quite surprised. It was very good to manage access points in a campus network setup that was good. There's a Cisco SD Access solution that I use. I forgot the name of it, to manage also the campus. It was also good. Yeah, I've used quite some Cisco product, but the one I can remember was the Cisco Wireless LAN Controller 9800.
We went with Cisco Catalyst Center, we evaluated, I think it was called Rainbow from Altel, Lucent Enterprise because we were an Alcatel-Lucent Enterprise customer. But since we seeded with Cisco DNA Center and SD Access back in 2019, we haven't been out to evaluate anything which is a direct competitor. There are tools which we are looking to purchase and implement to provide functionality which Cisco Catalyst Center can't, but they're more value add tools, not to necessarily directly drive the capability of our infrastructure.
Cisco ACI scales well and is suited in scenarios such as multi-cloud or large data centre implementations. It is not suited to smaller deployments as the efficiencies that it provides are not fully realised. It is well suited in large environments that contain both virtual and bare-metal machines allowing a great deal of flexibility. It is also perfect to support multi-tenancy platforms.
We've definitely spent quite a bit of time relearning how to do things in ACI, but I think the investment has been well worth while considering that we can now deploy tenants and leaves from the ground up in a matter of seconds.
We can if we choose to upgrade an entire datacenters worth of switches in a single night. (We've chosen to break it up for availability requirements, but if you didn't require 99.999% uptime like us you may be able to do it)
I have used it for upgrading devices, and it's does a great job at that, however out operations team for whatever reason has not adopted the feature.
Overall it feels like Cisco Catalyst Center has been huge waste of time. I feel like my time would be better spent on other projects and looking at other products and tools
