pipe - Optional flag to indicate that a ' netmap pipe' instance should be created. 
hw-addr - Optional ethernet address, can be in either X:X:X:X:X:X unix or X.X.X cisco format. This command has the following optional parameters: Where ' YYY' is an existing linux namespace. Where ' valeXXX' is an arbitrary name for a VALE interface that must start with ' vale' and is less than 16 characters. Once created, a new netmap interface will exist in VPP with the name ' netmap-', where ' ' takes one of two forms: #NETMAP DRIVER CHANGES DRIVERS#
- VPP development package for Netmap/VALE, which is a snapshot of the Netmap/VALE repo with minor changes to work with containers and modified kernel drivers to work with NICs.Ĭreate a netmap interface that will attach to a linux interface. Netmap/VALE generates the ' netmap.ko' kernel module that needs to be loaded before netmap interfaces can be created. #NETMAP DRIVER CHANGES PATCH#
Together, they provide a high speed user-space interface that allows VPP to patch into a linux namespace, a linux container, or a physical NIC without the use of DPDK. ' netmap' includes ' netmap pipes', a shared memory packet transport channel.
#NETMAP DRIVER CHANGES SOFTWARE#
' VALE' is an equally fast in-kernel software switch using the netmap API. ' netmap' is a framework for very fast packet I/O from userspace. If the driver is not in promiscuous mode, the packets are dropped or ignored because of the bad type/len field.Create netmap Summary/usage create netmap name |valeXXX:YYY. 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.
#NETMAP DRIVER CHANGES WINDOWS#
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.)
1-enabled (Receive bad/runt/invalid CRC packets. 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.
