Issue/Introduction

Industrial vSwitch (IvS) is used for manifacturing use case where realtime application is required. IvS can support low latency forwarding for industrial ethernet called Profinet. To run vDS as IvS, realtime configuration is required. This article describes how to confirm whether the configuration is applied to vSwitch correctly or not. 

Environment

Resolution

RT-vswich config needs to be enabled for each ESXi host to run a vDS as an IvS. And it is configured during deployment. To make sure that the config is enabled correctly, you can run the following command on the ESXi host. 

- SSH to a ESXi host
- Open the file of switches.yaml
- Check there is a line "EnsxDpVswitchRT: true"

[root@localhost:~] cat /etc/vmware/nsx/switches.yaml
EnsxDpVswitchRT: true
