Cisco Software-Defined Access (SD-Access) vs. OpenNMS Meridian

It's well suited in our corporate offices, where all our business users resides and where we can control all their accesses. What doesn't really fit well is when we have our branch fronts, where all the software domain access features aren't utilized to its fullest, due to the fact that customers and users don't really need to have all the security features that SDA provides.

I would recommend all system administrators use some form of network monitoring if they are not already doing so, and I'd definitely recommend people consider OpenNMS if they're shopping around. Small businesses will benefit from the low-cost of entry (it's free!), whilst getting all the enterprise features. Larger businesses can benefit from paid support plans.

However, there's no getting around the fact that you will require some advanced networking and sysadmin knowledge to get the most out of OpenNMS, or at least, be prepared for a steep learning curve. If you don't have the resources to devote this time initially, you may struggle.

• Fusion router: This roll in the fabric should be already integrated in the solution, right now it is configured manually.
• Bugs: Unfortunately the solution still present a lot of bugs, mainly in the controller.

• We've had a few issues with delayed alerting.
• I haven't quite figured out how to make topologies work yet, but I haven't spent a ton of time on it either.
• We've also had a bit of trouble importing some MIBs, but that usually boiled down to working with the vendor to make sure we had the right MIBs and dependencies.

As far as my experience with SD-Access -I'd say things that can be improved are - better functionality with ISE, ease to understand licensing and better documentation for configuration (add-ons, etc), and licensing.

OpenNMS's more attractive GUI and its price break were the main reasons our company chose to explore and use this product. However, it never managed to actually replace Nagios which had a much more established hold within the company. Perhaps we were over-monitoring, but our company claimed a $100k loss per hour of downtime.

• Initial adoption required quite a lot of resources and time to get everything right. Totally worth it for us; just be prepared for a gradual process that will get better and better with time.
• Once setup and running smoothly, it provides us with all the reporting we could hope for, at near zero cost.
• With OpenNMS, we're able to offer a much more reliable service to our customers, and spend a lot less time dealing with issues.
