We had some challenges for sure! We struggled with two different issues that had to do with our environment and nothing to do with Elan. For one thing it took us several hours to get our UCS environment working with the ACI managed distributed switch. We had to work with Cisco TAC to sort that out but we did get it working. The other issue we had was due to the way our ACI environment was deployed. It was setup so that all Layer 3 devices were sharing a single L3 out object and since we are using EIGRP that caused a limitation that basically required all policy enforcement to be disabled. That means all the contracts we created were useless since they couldn’t be enforced. I was very concerned that the second issue was going to be a show stopper for us and I was dreading telling management that after we spent all that money we couldn’t achieve our primary goals but we stuck it out and found a good solution to the problem. The solution does require a re-design of our ACI environment, but Elan helped us create and test the process to do it and it’s something we plan to do the first week in January. Overall I was very happy with how the training went and we learned a lot. Elan is top notch and I wouldn’t hesitate to recommend Firefly to others seeking assistance with their ACI deployment.
