Fix Recommendation

From the vSphere Web Client go to Networking >> Select a distributed switch >> Select a distributed port group >> Configure >> Settings >> Properties. Click "Edit" and change all Override port policies to disabled.

From a PowerCLI command prompt while connected to the vCenter server run the following commands:
$pgs = Get-VDPortgroup | Get-View
ForEach($pg in $pgs){
$spec = New-Object VMware.Vim.DVPortgroupConfigSpec
$spec.configversion = $pg.Config.ConfigVersion
$spec.Policy = New-Object VMware.Vim.VMwareDVSPortgroupPolicy
$spec.Policy.VlanOverrideAllowed = $False
$spec.Policy.UplinkTeamingOverrideAllowed = $False
$spec.Policy.SecurityPolicyOverrideAllowed = $False
$spec.Policy.IpfixOverrideAllowed = $False
$spec.Policy.BlockOverrideAllowed = $False
$spec.Policy.ShapingOverrideAllowed = $False
$spec.Policy.VendorConfigOverrideAllowed = $False
$spec.Policy.TrafficFilterOverrideAllowed = $False
$spec.Policy.PortConfigResetAtDisconnect = $True
$pg.ReconfigureDVPortgroup_Task($spec)
}

Check Contents

From the vSphere Web Client go to Networking >> Select a distributed switch >> Select a distributed port group >> Configure >> Settings >> Properties.

View the Properties pane and verify all Override port policies are set to disabled.

or

From a PowerCLI command prompt while connected to the vCenter server run the following command:
Get-VDPortgroup | Get-View |
Select Name,
@{N="VlanOverrideAllowed";E={$_.Config.Policy.VlanOverrideAllowed}},
@{N="UplinkTeamingOverrideAllowed";E={$_.Config.Policy.UplinkTeamingOverrideAllowed}},
@{N="SecurityPolicyOverrideAllowed";E={$_.Config.Policy.SecurityPolicyOverrideAllowed}},
@{N="IpfixOverrideAllowed";E={$_.Config.Policy.IpfixOverrideAllowed}},
@{N="BlockOverrideAllowed";E={$_.Config.Policy.BlockOverrideAllowed}},
@{N="ShapingOverrideAllowed";E={$_.Config.Policy.ShapingOverrideAllowed}},
@{N="VendorConfigOverrideAllowed";E={$_.Config.Policy.VendorConfigOverrideAllowed}},
@{N="TrafficFilterOverrideAllowed";E={$_.Config.Policy.TrafficFilterOverrideAllowed}},
@{N="PortConfigResetAtDisconnect";E={$_.Config.Policy.PortConfigResetAtDisconnect}} | Sort Name

Note: This was broken up into multiple lines for readability. Either paste as is into a PowerShell script or combine into one line and run.

This does not apply to the reset port configuration on disconnect policy.

If any port level overrides are enabled and not documented, this is a finding.
