Cisco Catalyst Center (formerly Cisco DNA
Center) is a network management system that leverages AI to connect,
secure, and automate customer’s network operations. It harnesses the Catalyst family of switching and wireless through AI-enabled
automation that simplifies the IT experience and streamlines complex network
operations. Offering
operational flexibility, Cisco Catalyst Center can be deployed on-premises on a
physical appliance or in a VMware virtual environment, or in a…

Riverbed OPNET Network Modeler, from San Francisco based Riverbed Technology, is network optimization technology.
I think if you have Cisco infrastructure and you are looking to do a big hardware install per se, the plug-and-play feature is really helpful to be able to really quickly push out a config to a bunch of switches. That was really helpful for us. It really sped things up. If you need to push out configuration changes to a bunch of switches at once, it can be helpful, I guess if you plan it out. I guess that's the part I'm struggling with is trying to figure out how to streamline that process, but it has the potential there to be really helpful.
Riverbed Modeler is well suited for wireless, wired, ZigBee, and Cisco networks. All these scenarios are efficiently designed and simulated using Riverbed Modeler, as all the devices are available in its object pallet, so we just need to drag and drop for the best scenario design in the given dimensions. The simulation results are around 95% accurate. However, it is not suited for data security, as data encryption algorithms are not available in Riverbed Modeler.
I want to hammer home this swim process. It is amazing how you can upgrade something. It does all the readiness checks for you, does all the compliance checks for you, and it eliminates a lot of potential human error. Maybe you won't copy a file correctly, maybe you didn't check your MD five hash properly. There's a lot of things that if you're doing 50, 60, 70 upgrades over the course of a week or two weeks, you might try to cut corners, or not intentionally, but just human error. You do something repetitive, maybe you skip a step with swim, there is no skipping a step. It checks compliance, it checks your iOS, you download your iOS straight from Cisco from Catalyst Center. It eliminates any fatigue that you might have whenever it comes to doing repetitive things for weeks on end.
We started using the product quite early and as I understand it was quite a new product for Cisco, so it's been developed quite aggressively. So even though we thought we were running the latest recommended version, a month later we realized that we are so much behind that it might take a week to upgrade to the latest recommended versions. In a way, it's good because it's developed so fast, but it's hard to keep up with all the implementations. And last upgrade for us took three weeks because we were so behind and it just takes longer because we've got large-scale deployment.
Riverbed Modeler needs to improve the scenarios of LAN MAN WAN, as the available scenarios under all of these follow a simple area structure that's not connected to the ISP when it comes to simulation. This generates dummy traffic.
Riverbed Modeler also needs to work on the selection of result sets so that, as with most designed networks, we can select any result parameter to show. All the parameters are displayed, whether they are relevant or not. It needs to display only relevant result parameters to select.
The back-end TCP/IP model needs more clarity to expose the structure to some changes.
We utilize Cisco Catalyst Center frequently for many tasks including SWIM and vulnerability mitigation which has provided better options than manual processes
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.
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 software upgrades and ability to integrate with the wireless telemetry data set Cisco DNA Center ahead. However the automation with Change Control, Intent and better path mapping (even across MPLS and WAN Circuits) make NetBrain a needed tool to get that gives you that visibility and flexibility. Solarwinds has the ablity to view Netflow which would be an interesting add to DNA Center or an easier path to get or integrate with Stealthwatch.
The only thing comparable to OPNET is Packet Tracer, which is basic and very limited. Packet Tracer in terms of tool comparison between the two is like OPNET's stone-age relative.
Initial cost is pricy, but management needs to understand the value this provides so make them aware
Reporting could be improved in more detail in our opinion, but it gives a great overview of your environment. High level overview for managers would be greatly appreciated with as little or much detail as needed for certain Cisco gear.
Does not work as well with some older Cisco equipment because they want you to buy new, again the cost impact comes into play.
It comes with a costly paid license, but simulating the network before actual deployment saves a lot of costs, in case after deployment we feel performance is not good and we need to change. This would waste a lot of money, but Riverbed saves this money.
Its OPNET GURU academic edition is available free of cost, but with limited functionality, which is good for students in maximum case. This will degrade our sale of Riverbed Modeler.
A one-time investment in Modeler saves a lot of cost regarding networks, topology, designing, and provides a lifetime license with updates.
