Cross vCenter universal logical switch creation


Okay! We need to check a few prerequirements for logical switch creation to ensure that we are able to create the logical switch at the same time and it is functioning as expected. The following are the key points that should be followed while creating a universal logical switch:

  • A VSphere distributed switch should be configured

  • Controllers must be deployed in the primary NSX Manager

  • VSphere Host clusters must be prepared for NSX

  • VXLAN must be configured

  • A universal segment ID pool must be configured (should not overlap with local segment ID)

  • A universal transport zone must be created

Let's go ahead and create a universal logical switch:

  1. In vSphere web client, navigate to Home | Networking & Security | Logical Switches.

  2. Select the NSX Manager on which you want to create a logical switch (this should be the primary NSX Manager; if we select the secondary NSX Manager, it won't be universal object selection).

  3. Click the New Logical Switch icon.
