5506-X span/port mirroring?

[me77]

I am trying to do something like this for the ASA 5506-X:

I found this, which states that port mirroring is possible on the 5505:

But the 5506-X uses BVI (I am currently running FTD 6.2, will be reimaging to ASA eventually.)

So all the ports act as a common gateway, with a common IP address. But I don't see common traffic when I sniff one port.

what dont you use tcpdump to acpture packets?

I'm not trying to do a tcpdump solution, I'm looking for a way to mirror the port. My FTD is unlicensed so I'm looking for a long-term ASA solution with port mirroring, rather than an FTD solution.

I get an error when I try to run the monitor session command, saying I don't have the correct license.

What is the license I should purchase for my client to get the monitor session command to work, Apex?

Thanks,
