Testing Junos 15.1X49 on vSRX, and how JTAC responded to a bug

As OneConfig is part of the Juniper Beta Program, we were happy when the new version of Junos 15.1 was released in August. We enjoyed putting it through its paces in the months prior to release, so to see it out in production was exciting.

While the beta testing was successful, we unfortunately found a bug in the actual 15.1X49 release that caused a fault with devices connecting to OneConfig. We notified the JTAC and worked closely with them to get this issue diagnosed and fixed. The JTAC were very professional and thorough in their approach, especially considering what a difficult problem it was to reproduce involving OneConfig's external system. We were assigned a great JTAC engineer who was really keen to learn about OneConfig's platform and he spent considerable effort learning how the OneConfig platform works whilst troubleshooting the issue.

The JTAC confirmed the issue and worked with us to do some further testing on a short term work around. Only 2 weeks later a fix was released in vSRX 15.1X49-D20. We've upgraded our vSRX test lab and everything is now working well again!

We have a growing number of customers using Juniper's vSRX for different use cases in both hosting and CPE environments. We love that our platform can support these use cases in either physical SRX devices or the virtual environments, and it is very exciting to see the uptake of these services growing.  

15.1X49 vSRX brings a load of exciting new features and performance improvements. Things like transparent mode, UTM and AppFW. If you want to read more, check out the release notes here: http://www.juniper.net/techpubs/en_US/junos15.1x49/information-products/topic-collections/release-notes/15.1x49/index.html
