The main use cases for Cisco Catalyst SD-WAN are in the retail sector and enterprise. The product is used for Cisco routing, specifically for configuring traffic engineering with protocol BGP.

With Cisco Catalyst SD-WAN, I have centralized orchestration and management. The transport independence of MPLS or connectivity and internet connectivity is another excellent feature. End-to-end segmentation is also provided.

I use the application-aware routing feature. Cisco Catalyst SD-WAN supports dynamic police-based routing decisions based on application type or different performance metrics such as jitter or latency.

The benefit of that feature is that it improves user experience. The principal benefit of application-aware routing is that critical applications are prioritized or routed over the best performing paths to reduce outages and service degradation. There is full visibility of applications.

Cisco Catalyst SD-WAN has integrated security features which include base firewall, URL filtering, IPS, and secure segmentation, and it supports integration with other Cisco products such as Umbrella or Snort. This feature is beneficial for the client because the information is secure.

It is important that Cisco Catalyst SD-WAN supports cloud, on-premises, and hybrid environments for my organization because it allows for scalability and faster deployment in the cloud. It reduces operational needs because I don't need to manage physical controller hardware, and updates and maintenance can be centralized and automated.

The zero-touch provisioning feature is very important for the speed of deploying new branch locations. I can deliver the device to the branch, and it is important because simplified deployment makes the implementation start more easily since devices are auto-configured and authenticate without manual intervention.

Cisco can improve Cisco Catalyst SD-WAN by simplifying licensing and platform integration with other Cisco products such as Catalyst Center or solutions with Meraki.

A license needs to be permanent for me. The client feels that it is very expensive.

I have used Cisco Catalyst SD-WAN for two years.

I have experience with the Cisco Provider Connectivity Assurance, but I haven't configured it. I am currently working in pre-sales.

I would rate Cisco's support, their customer service, and technical support as excellent. The support of Cisco is very good, and the attention is immediate.

I have sixteen years of work experience in enterprise architecture with Cisco, including networking, switching, routing, and solution SD-Access.

AWS is the main cloud provider in my use cases.

My company, Sonda, is a Gold partner of Cisco.

I am a solution architect at Sonda.

I rate this solution 10 out of 10.

The main use cases for Juniper vSRX would be primarily for a data center scenario device, and there's a significant focus on the other core elements.

Cisco Catalyst SD-WAN's main use cases for us will be data center deployment for enterprise level.

The most useful feature for Cisco Catalyst SD-WAN is the single pane of glass management because we also use Meraki onsite. It's a standard Cisco solution, and because Cisco is who they are and what they can provide, we use Cisco for compute and network, and we use NetApp for storage, so that's what we generally do.

I have absolutely seen scenarios where the decentralized management capability improved operations and workflows.

There's nothing I could put my finger on right away for improvements in Cisco Catalyst SD-WAN. There is definitely nothing that Juniper does that Cisco doesn't do. Cisco will do everything Juniper does and then some. The negative, or the downside of Cisco is the knowledge base; you need to be a little bit more tech-savvy and network-savvy to work with Cisco, while Juniper is a lot more user-friendly from what I can see, especially in terms of configuration and any kind of roll back. But in terms of market leaders, Cisco is capable of doing anything you want it to do, as far as I can see.

I have just recently been working with Juniper.

I have contacted Cisco support for one-on-one support for a very unique or bespoke configuration where there are a lot of rules and policies going on in the background, maybe some interconnecting or conflicting with one another, but in terms of the actual product or problems with the product, nothing I'm aware of.

I would consider Cisco support a 10 out of 10.

In my experience, customers are realizing the return on investment with Cisco in 12 months. Within the year, I've done work with customers in the last couple of years that we've upgraded from Avaya six to Cisco Catalyst SD-WAN in a Cisco network environment, and they are now back to do that with the remainder of their company, so they've realized the value in 12 months and are willing to invest in the remainder of their organization.

I am working on the Juniper vSRX solution.

I work with switches, routers, firewalls, and any IT consultant tasks, and I work at the core. I have a CCNA, and I'm actually doing a Juniper certification exam in 3 hours, so I continually work on upskilling, as part of what I do.

If it's enterprise level, you'll deploy your Cisco Catalyst SD-WAN in a couple of hours. You can draw it down there if you've already got a Catalyst or an existing environment. If you are starting up from scratch, it's hard to put a timeframe on it because it depends on criteria, but if you're replacing something with a Cisco Catalyst SD-WAN and you know what you're doing along with using the CLI and your backups, a couple of hours would be plenty of time, a half a day or maybe a little bit more wouldn't hurt.

There are AI features, and I'm not 100% privy to them because I just haven't been involved in that element, but they do exist.

I would rate Cisco Catalyst SD-WAN an eight.

The primary use case for Cisco SD-WAN is the standard configuration across all sites, facilitated by templates. This solution helps in the ease of management and compliance configuration, which is deployed everywhere. 

It also simplifies troubleshooting and provides full mesh topology for branch connectivity to data centers. All branch locations, along with central locations, are on SD-WAN and gathered in the data center. Many customers combine it with local Internet breakout for SaaS applications.

The valuable features of Cisco SD-WAN include its security policies and zone-based firewall that are applied to every site, as well as application-aware routing. Security is standard compliant, eliminating config drift that was prevalent before manual configurations. Application-aware routing offers flexibility in using different lines for traffic, depending on the policy implemented.

The main area for improvement in Cisco SD-WAN is the lack of documentation, which often lags behind the software releases. This is especially notable since Cisco acquired the solution and is still integrating it into its overall environment.

I have been using Cisco SD-WAN for the last three years.

I would rate Cisco SD-WAN an eight out of ten for stability. While some software-related issues and bugs were encountered, they did not cause the whole environment to crash. Sites were able to continue functioning, although there were limitations in making changes at those times.

The ease of configuration and features like zero-touch provisioning enhance the scalability of Cisco SD-WAN, especially in disaster recovery situations. I would rate scalability a nine out of ten. The initial implementation faced some issues, but it has improved with newer software versions.

The customer service and support for Cisco SD-WAN are satisfactory, rated as eight out of ten. 

However, Cisco's ongoing reorganizations have affected the quality of technical support, which varies depending on the engineer handling cases.

Before Cisco SD-WAN, I used traditional MPLS or eVPN, IPVPN networks. The switch was made for easier management and standard compliance, which is enforced by the SD-WAN product itself.

The initial setup involves getting the underlay and controllers in place to migrate from the old to the new network. I deployed in parallel, allowing both networks to coexist, and then migrated sites to the new central control plane.

For a complete project, we had two central administrators and designers, along with three or four teams managing the remote locations. The process took approximately one year to migrate about 280 sites.

The pricing for Cisco SD-WAN is rated eight out of ten, with some variability depending on the reseller discounts and the size of the enterprise. It is also relatively cost-effective for smaller businesses when using the Meraki version.

We evaluated other solutions but chose Cisco SD-WAN due to its flexibility, support for our requirements, and the preference of many of our customers who were already using Cisco-based solutions.

I would recommend working out detailed use cases and requirements before implementation. Cisco SD-WAN is quite flexible, however, without a solid foundational design, users might struggle with too many options, leading to a poor rollout design. 

Overall, I rate Cisco SD-WAN as nine out of ten.

The primary use case for Cisco SD-WAN is to connect multiple offices or branch offices across the globe or within a country securely. It facilitates branch-to-branch or office-to-office transactions and provides easy access to primary data centers.

Cisco SD-WAN is valued for its operational efficiency and ease of operation. It allows prioritization of packages based on production requirements, and integration capabilities provide comprehensive security. Integration with Cisco ISE, Cisco Firewalls, and other Cisco solutions is beneficial. Furthermore, it is appreciated for its insights, visibility, and ease of use.

Integration with other OEMs and the API part needs improvement to be more user-friendly, especially in terms of GUI. Including more features like integrating with Splunk for monitoring vulnerabilities would help eliminate the need for other SOC solutions.

I have been working with the Cisco SD-WAN solutions since 2018.

I have not faced any stability issues with Cisco SD-WAN.

Cisco SD-WAN is highly scalable and can be expanded to more than 10,000 sites, so there are no issues with scalability.

The initial setup is not straightforward, as it requires experienced personnel to size and optimize the solution. Otherwise, it could be costly.

For Cisco SD-WAN deployment, following Cisco's published best practices is advisable, starting with vManage and then adding all devices for better remote control.

Operational ROI is observed by cutting down internet and branch connectivity costs, while securely accessing hosted applications using various types of connectivity like 3G, 5G, or MPLS.

Cisco SD-WAN is a premium product priced on the higher side, however, its pricing is justifiable due to the comprehensive solution it offers.

I have evaluated Aruba and Fortinet SD-WAN solutions.

For enterprise customers with significant security concerns, Cisco Catalyst SD-WAN is a recommended choice. It offers comprehensive integration under a single umbrella, which is advantageous compared to other OEMs. 

I would rate the overall solution as a ten out of ten.

We are working with telecom companies and many government companies. The main request is to tie the branches, separate the bandwidth depending on the application, and have a unified orchestrator to see all these connections from one centralized management center.

SD-WAN provides a range of common benefits, including cost reduction, increased visibility, and scalability. It can be seen as a replacement for MPLS. This applies to all vendors, not just Cisco. When someone requests SD-WAN from Cisco, they already recognize its value within their environment.

It is expensive.

Viptela is one part of SD-WAN that can give you an internet connection with the help of stacking. You can create a stack in the environment called a TLOC. With the help of TLOC, you can configure your ISPs in one bundle, giving you the network's resiliency. The best part is that you will get a few connections immediately onto your network.

If one of your ISPs goes down or has latency in your environment, Cisco SD-WAN will detect the issue and explain why the ISP is down. This is the solution's best feature, as it allows you to monitor your ISP links very well from their side. The solution's configuration is easy and not that hard. The solution's central management allows you to raise cases and get support.

My client wants to use SD-WAN to reduce their line costs. By using SD-WAN, they aim to lower transport costs and better use internet traffic and bandwidth.

Clients use SD-WAN, which encapsulates the packet into a VPN tunnel. This allows them to be ready. In SD-WAN, the internet line is generally much cheaper than other lines. For example, they can use DIA to access internet traffic. With strong encryption, such as TLS or IPsec, they can securely send business traffic over the internet at a lower cost.

It depends on the customer’s requirements. In our area, Taiwan, we help users build SD-WAN. They are only using SD-WAN for transport. They want multitasking and QR code functions enabled.

Customers collaborate with ISPs and currently work with three ISPs, using options like LSM VPN and MPLS VPN to reduce line costs. They are considering moving from their current setup to an MPLS VPN and might also consider using a DIA line for internet access. However, due to government regulations and audits of internet access, they are cautious about using an internet line. They are still deciding which bank should be the first to implement this change.

If I want to improve the SD-WAN in the future, they might consider integrating it with technologies like SignalR and SRv6 into the SD-WAN control plane. This would enhance functionality, such as SRv6 video capabilities. They can simply use an SD-WAN solution based on SRv6.
