The order of vmnic# may change when running Get-VirtualSwitch command

Products

• VMware vSphere ESXi

Issue/Introduction

When using the Get-VirtualSwitch command to display NICs, they are typically listed in ascending order as follows:

PS C:\Users\Administrator>  Get-VirtualSwitch | Select-Object Name,Nic,Mtu

Name     Nic               Mtu
----     ---               ---
vSwitch0 {vmnic0, vmnic1}  1500

However, in rare cases, the order may differ as follows:

PS C:\Users\Administrator>  Get-VirtualSwitch | Select-Object Name,Nic,Mtu
Name     Nic               Mtu
----     ---               ---
vSwitch0 {vmnic1, vmnic0} 1500

Resolution

This is normal behavior. You can ignore and use "Get-NicTeamingPolicy" command if you need to check the priority of NIC failover.
