Diagnosis of the mirror port

[chmey]

Is your feature request related to a problem? Please describe.
When installing the system, administrators want to make sure the mirror port is configured correctly.

Describe the solution you'd like

• run and parse something like tcpdump/ nethogs on the mirror interface
• Parse if packets are retrieved on mirror interface (promiscious)
• Display parsed networks/IPs from the mirror traffic somewhere in the administration panel

Describe alternatives you've considered
Used tcpdump to manually verify if traffic is seen on the mirror interface.
