Industrial vSwitch not working post upgrade VCF to 9.0.1

Products

• VMware NSX

Issue/Introduction

Below symptoms could be seen post upgrade to VCF 9.0.1

• IO devices are not reachable from vPLC vms.
• "insufficient bandwidth / duplex on all ports" observed on vPLCs.
• Profinet Connectivity is broken for physical devices and virtual devices
• IO devices are not seen on node list (nsxdp-cli ens prp node list)

Environment

VMware NSX

Cause

Underlying physical connectivity between IO device and vPLC vm

Resolution

• Make sure that there is no physical connectivity issues between IO devices and ESXi hosts where vPLC vms resides
• Take packet captures on associated ESXi vmnics where vPLC vms resides to confirm if we see any packets from the IO devices
• Reference: Troubleshooting NSX using Packet Captures

Note: Make sure that we have below advanced configuration on the .vmx file of vPLC vms to be able to support higher speed
