vDS uplink configuration check for IvS

Products

• VMware NSX

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. VDS requires additional realtime configuration to run as an IvS. This KB article describes how to check the configuration of realtime settings from ESXi CLI.

Environment

4.2.x

Resolution

The configstorecli command can show the vDS configuration on the ESXi host. If the realtime settings are configured correctly, you can see that “allowed” is set to “true” under real_time_settings. This means this vDS is running as an IvS. Also, this command output shows uplink settings for LAN A and LAN B of Profinet. These configurations should match with the ones in Transport Node Profile in NSX.

- SSH to a ESXi host where IvS is enabled
- Run the configstorecli command and find "real_time_settings".

[root@localhost:~] configstorecli config current get -c esx -g network_vds -k switch_solutions
