VxRail Network Environment Requirements and Initialization

A deployment engineer executes the following commands on every node in a new VxRail deployment, and VLAN ID 3940 is added to the ToR switches:

esxcli network vswitch standard portgroup set -p "Private Management Network" -v 3940  
esxcli network vswitch standard portgroup set -p "Private VM Network" -v 3940  

No nodes are discovered by VxRail Manager.

What is causing this issue?

Explanation

VxRail node discovery relies on the VMware Loudmouth service and the internal management VLAN. Changing the VLAN assigned to the private discovery port groups requires restarting Loudmouth so the service resumes discovery using the updated network configuration. The same VLAN can be assigned to both the Private Management Network and Private VM Network, and the default discovery VLAN is not mandatory.
