The driver cannot send packets either on its own or through a call to its MiniportSendNetBufferLists function.

If your application uses WinPcap (as does, for example, Wireshark), it can't put the driver into "network monitor" mode, as WinPcap currently doesn't support that (because its kernel driver doesn't support version 6 of the NDIS interface for network drivers), so drivers that follow Microsoft's recommendations won't allow you to put the interface into promiscuous mode.Īnd if it could put it into monitor mode, that might disable transmitting packets according to this Microsoft page on monitor mode, "While in NetMon mode, the miniport driver can only receive packets based on the current packet filter settings. This is Windows, and the adapter is a Wi-Fi adapter, and, according to this Microsoft documentation on 802.11 drivers on Windows, "It is only valid for the miniport driver to enable the NDIS_PACKET_TYPE_PROMISCUOUS, NDIS_PACKET_TYPE_802_11_PROMISCUOUS_MGMT, or NDIS_PACKET_TYPE_802_11_PROMISCUOUS_CTRL packet filters if the driver is operating in Network Monitor (NetMon) or Extensible Access Point (AP) modes." If the driver is not in promiscuous mode, the packets are dropped or ignored because of the bad type/len field.You might not be able to put that adapter into promiscuous mode.

Your capture software is responsible for enabling promiscuous mode in your driver. For support and information on loading the 802.1q module, contact your distribution. This step automatically enables the Intel Networking hardware offload capabilities to offload VLAN tag stripping and insertion. To strip VLAN tags: Load the kernel supplied 802.1q module. You must restart Windows for the registry change to take effect.īy default, the driver in promiscuous mode does not strip VLAN tags. Do not strip VLAN tags and ignore packets sent to other VLANs as per normal operation.) The mode you need to capture traffic thats neither to nor from your PC is monitor mode.

1-enabled (Receive bad/runt/invalid CRC packets. Promiscuous mode doesnt work on Wi-Fi interfaces.

When creating or modifying registry dword MonitorMode, set the dword value to one of the following options:

0-disabled (Do not store bad packets, Do not store CRCs, Strip 802.1Q vlan tags).

When creating or changing registry dword MonitorModeEnabled, set the dword value to one of the following: This change is only for promiscuous mode/sniffing use. Have a skilled technician make the changes to the registry. CautionĬhanges to the registry can disable your system. Where nn is the physical instance of the network port where you want to capture the VLAN tags. ControlSet001 might need to be Current Control Set or another 00x number. HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\\00nn This registry entry is only supported on Intel drivers.

Drivers included in Windows might not include support for promiscuous mode.

To understand which driver to use, see How do I identify my wired Ethernet adapter and driver version?.

The driver used impacts the registry change required: Adapter Driver To allow tagged frames to pass to your packet capture software, add a registry dword and value, or change the value of the registry key. We recommend using the latest driver version available. Most of the drivers have this feature now. In some drivers, the registry change does not allow the type of tags to be passed.

The tagging frames get stripped out by the driver however, making a registry change can be done in order to see the tags.

After changing the adapter registry setting in Windows*, you must restart Windows for the new registry setting to work.

My sniffer is not seeing VLAN or QoS tagged frames.
