Get-MacLearn -DVPortgroupName we can see from the output, I currently do not have MAC Learning enabled on this DV Portgroup.

The Get-MacLearn function can be used to retrieve the current MAC Learning configuration for a given DV Portgroup, simple run the following command which can accept a one or more DV Portgroup names:

You will need to make sure to download the latest PowerCLI 10.1.0 release which adds support for vSphere 6.7 To demonstrate the new MAC Learning APIs, I have created two small PowerCLI functions called Get-MacLearn and Set-MacLearn which you can download from here. This new MAC Management Policy will also be the new preferred method for managing security policies going forward for a DV Portgroup and the previous security policy settings should no longer be used.ĭisclaimer: Nested ESXi is still not officially supported by VMware. For those that have used the VDS API to manage their VDS, you will simply use the existing ReconfigureDVPortgroup_Task() method and in 6.7, there now a new macManagementPolicy property which allows you to enable and define your MAC Learning settings. MAC Learning can be enabled on a per Distributed Virtual Portgroup bases and today, it is only available when using the vSphere API.

To use the new MAC Learning functionality, you will of course need to upgrade to vSphere 6.7 (both vCenter and ESXi) but also upgrade to the latest VDS version which is 6.6. For customers who are still running ESXi 6.0 or 6.5, you should continue to use the Learnswitch Fling until you fully upgrade to vSphere 6.7. Not only will this benefit Nested ESXi workloads but also other solutions and use cases that have historically required the use of promiscuous mode. Today, I am pleased to announce that with the release of vSphere 6.7, the MAC Learning functionality is now available as a native feature of the VMware Distributed Virtual Switch (VDS) and as some of you may have guessed from the title, promiscuous mode is also no longer a requirement for running Nested ESXi! I wanted to take a moment and thank Subin, Jobin, Sriram, Rajeev & Samuel from our Network and Security Business Unit (NSBU) at VMware who worked tirelessly to get this integrated and productized into ESXi. The most recent solution was a new Learnswitch VMkernel module (released as a VMware Fling) that enables MAC learning capabilities on ESXi.

Although these solutions worked extremely well, it however did require users to install additional software to enable this functionality. And if you make your device forget the network, it will also forget the private address it used with that network, unless it has been less than 2 weeks since the last time it was made to forget that network.Over the years, several solutions have been developed here and here to help reduce the impact of promiscuous mode, which is a requirement for running Nested ESXi as a workload.

Starting with iOS 15, iPadOS 15, and watchOS 8, if your device hasn’t joined the network in 6 weeks, it uses a different private address the next time it connects to that network.

If you erase all content and settings or reset network settings on the device, your device uses a different private address the next time it connects to that network.

In some cases, your device will change its private Wi-Fi address: This unique MAC address is your device's private Wi-Fi address, which it uses for that network only. Starting with iOS 14, iPadOS 14, and watchOS 7, your device improves privacy by using a different MAC address for each Wi-Fi network. This allows a kind of user tracking or profiling, and it applies to all devices on all Wi-Fi networks. If the device always uses the same Wi-Fi MAC address across all networks, network operators and other network observers can more easily relate that address to the device's network activity and location over time. To communicate with a Wi-Fi network, a device must identify itself to the network using a unique network address called a Media Access Control (MAC) address.
