Powercli to check VM and ESX network info

1. Check all VM's VMnic on which ESX phyiscal NIC:

get-esxtop -CounterName Netport | Select PortID, ClientName, TeamUplink

2. Check dedicated VM

get-esxtop -CounterName Netport | Where-Object { $_.ClientName -like "PRABC*" } | Select PortID, ClientName, TeamUplink

or

get-esxtop -CounterName Netport | Where-Object { $_.ClientName -match "PRABCAD01" } | Select PortID, ClientName, TeamUplink

3. Check the NIC card driver

$esxcli.software.vib.list.Invoke() | Where { $_.Name -contains "elxnet" } | select Name,ID,Version,InstallDate

4. To get a list of network adapters on a host

Get-VMHostNetworkAdapter -VMHost "ESX03"

5. Check CDP info for the hosts of abc cluster

Get-Cluster abc | Get-VMHost | Get-VMHostNetworkAdapterCDP | Where-Object {$_.connected -eq "True"} | Export-Csv -notypeinformation -Path c:\temp\cdp.csv

Need add function first

function Get-VMHostNetworkAdapterCDP {
<# .SYNOPSIS Function to retrieve the Network Adapter CDP info of a vSphere host. .DESCRIPTION Function to retrieve the Network Adapter CDP info of a vSphere host. .PARAMETER VMHost A vSphere ESXi Host object .INPUTS System.Management.Automation.PSObject. .OUTPUTS System.Management.Automation.PSObject. .EXAMPLE PS> Get-VMHostNetworkAdapterCDP -VMHost ESXi01,ESXi02
