Configure external network traffic to allow Virtual Network Sensor to monitor data.
Procedure
- On the host machine, access the Hyper-V Manager.
- Verify the virtual switch connecting to the Virtual Network Sensor data port has the connection type set to External network.
- Set the Virtual Network Sensor as the traffic mirror target.
- Right-click the Virtual Network Sensor virtual machine, and select Settings...
- In the settings window, use the navigation bar to go to .
- Under the Port mirroring section, set Mirroring mode to Destination.
- Click Apply, then click OK.
- Access PowerShell.
- Use the following commands to configure the monitor mode of the data
port.The example code uses
Data Switch
as the name of the switch the data port connects to.$DataSwitch = "Data Switch" $extFeature = Get-VMSystemSwitchExtensionPortFeature -FeatureName "Ethernet Switch Port Security Settings" $extFeature.SettingData.MonitorMode = 2 Add-VMSwitchExtensionPortFeature -ExternalPort -SwitchName $DataSwitch -VMSwitchExtensionFeature $extFeature
- Use the following commands to configure the VM VLAN mode of the data
port.These commands are used to set the VLAN ID to be mirrored. The example code uses
VirtualNetworkSensor_0101
as the target VLAN to mirror traffic from.$DataSwitch
is the name of the switch the data port connects to.$VMName = "VirtualNetworkSensor_0101" $DataSwitch = "Data Switch" Get-VMNetworkAdapter -VMName $VMName | ? SwitchName -eq "$DataSwitch" | % { Set-VMNetworkAdapterVlan -VMNetworkAdapter $_ -Trunk -AllowedVlanIdList 1-4094 -NativeVlanId 0 }
After configuring your network settings, access the Virtual Network Sensor console and use the commandshow traffic
to verify the Virtual Network Sensor is receiving traffic. For more information about troubleshooting, see Virtual Network Sensor FAQ and Virtual Network Sensor CLI commands.
