VMware NSX 6.2.3 has been released on 09-June 2016, see the Release notes – What’s new section.
One big new feature introduced is the support for 3rd-party hardware L2 gateway integration, useful for instance when migrating physical workloads into an “NSX enabled” environment (don’t forget the controllers see issue 1477280).
Then it comes to VXLAN UDP port which changed from 8472 to 4789. I won’t list all the new features (you can use the release notes for that) instead I will simply quote some of the new functionalities I consider most interesting or issues to keep an eye on.
- NSX Edge on Demand Failover: good for testing
- Edge Firewall SYN flood protection: disabled by default, can be enabled via REST call. Particularity useful when the ESG is exposed publicly on the WAN
- SNMP v2c support
- global Dashboard to monitor quickly the overall health of your NSX environment
- the new license model implements the default license upon install which is “NSX for vShield Endpoint”, which enables use of NSX for deploying and managing vShield Endpoint for anti-virus offload capability only
- Fixed issue 1456172 good to have some warnings displayed, NAT has been part of the firewall service however people tend to forget that is the firewall is disabled so is the NAT
- Fixed issue 1619570: In a large-scale DFW configuration with millions of rules and Service Composer, rule publishing may require several seconds to complete after a reboot. During this time, new rules cannot be published —-> ok this one made me laugh a bit, millions or rules? really? won’t comment any further 😉
- Issue 1529178: Uploading a server certificate which does not include a common name returns an “internal server error” message
- Issue 1534606: Host Preparation Page fails to load when NSX Managers are running different versions
- Issue 1386874: Networking and Security Tab not displayed in vSphere Web Client
- Issue 1604506: Cannot deploy DLR without NSX Edge VM if using default gateway for static routing use case see KB 2144551
The list of fixes os huge this time so triple check and spend some hours reading through all of them when planning to upgrade.
