Resolution: |
For port mirroring, it is necessary to enable "monitor mode" on the vSwitch with the following commands (with administrator privileges): $portFeature=Get-VMSystemSwitchExtensionPortFeature -FeatureName "Ethernet Switch Port Security Settings"
It is possible to verify the configuration with: Get-VMSwitchExtensionPortFeature -FeatureName "Ethernet Switch Port Security Settings" -SwitchName "NameOfCreatedSwitch" -ExternalPort | select -ExpandProperty SettingData
It is recommended to enable VLAN monitoring even if the VLANs are not used at the time of configuration: $VMNetAdap = Get-VMNetworkAdapter -VMName "NameOfCreatedVirtualMachine" It is possible to verify the configuration with: Get-VMNetworkAdapter -VMName "NameOfCreatedVirtualMachine" |
