Determining the number of PRP VDAN nodes per ESXi host

Products

• VMware NSX

Issue/Introduction

Industry vSwitch (IvS) supprots Parallel Redundancy Protocol (PRP) that can be used with industrial ethernet called Profilnet. An IvS with PRP enabled acts as a PRP Redbox that can provide both LAN-A and LAN-B redundancy connectivity for the node that doesn't have PRP capability. Each node vNIC connected to the IvS is called Virtual Dual Attached Node (VDAN). IvS can support up to 12 VDAN node per host.

The question is how to get the total number of VDAN nodes per host.

Environment

4.2.x

Resolution

In order to get the info, you can follow the steps below:
 - Get the MAC addresss of the NIC that is connected Profinet network
 - Login to the ESXi Host via SSH
 - Run and find the DvsPortset name for the MAC address

net-stats -l

 

 - Run and find Switch ID (swID) for the DvsPortset

nsxcli -c get ens switch list

 

 - Run and find the entry for the MAC address in the vdan table output

nsxcli -c get ens prp vdan list <swID>

- Check the bottom of the output. There is the info about total PRP vDANs.
