Brian Lich|Last Updated: 3/8/2017

SYNOPSIS

Disables link level flow control based on the IEEE 802.1p priority.

SYNTAX

ByIfAlias (Default)

Disable-NetQosFlowControl [[-Priority] <Byte[]>] [[-InterfaceAlias] <String>] [-PassThru]
 [-CimSession <CimSession[]>] [-ThrottleLimit <Int32>] [-AsJob] [-WhatIf] [-Confirm] [<CommonParameters>]

ByIfIndex

Disable-NetQosFlowControl [[-Priority] <Byte[]>] [[-InterfaceIndex] <UInt32>] [-PassThru]
 [-CimSession <CimSession[]>] [-ThrottleLimit <Int32>] [-AsJob] [-WhatIf] [-Confirm] [<CommonParameters>]

InputObject (cdxml)

Disable-NetQosFlowControl -InputObject <CimInstance[]> [-PassThru] [-CimSession <CimSession[]>]
 [-ThrottleLimit <Int32>] [-AsJob] [-WhatIf] [-Confirm] [<CommonParameters>]

DESCRIPTION

The Disable-NetQosFlowControl cmdlet disables priority-based flow control (PFC) in Windows Server® 2012 and later. PFC is part of the IEEE data center bridging (DCB) standard. If Windows Server 2012 or later is configured to be not willing to accept configurations from a remote device, Windows Server 2012 or later programs DCB capable network adapters, which disables PFC at the link level.

For more information about remote device configurations, see the Set-NetQosDcbxSetting cmdlet.

For more information about PFC, see the Enable-NetQosFlowControl cmdlet.

EXAMPLES

Example 1: Disable flow control on traffic for a priority

PS C:\> Disable-NetQosFlowControl -Priority 6

This command disables flow control on traffic tagged with priority 6.

PARAMETERS

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet.

For more information about Windows PowerShell background jobs, see about_Jobs.

INPUTS

Microsoft.Management.Infrastructure.CimInstance#ROOT/StandardCimv2/MSFT_NetQosFlowControlSettingData[]

The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object. The MSFT_NetQosFlowControlSettingData object contains the flow control setting per priority.

OUTPUTS

Microsoft.Management.Infrastructure.CimInstance#ROOT/StandardCimv2/MSFT_NetQosFlowControlSettingData

The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object. This cmdlet returns a MSFT_NetQosFlowControlSettingData object that contains flow control settings per priority. Only if the PassThru parameter is specified does this cmdlet return the MSFT_NetQosFlowControlSettingData object.
