Dear all,

I would like to ask some suggestion that ASA 5515X port (L3) is support port mirroring or not coz i want to do mirror all traffic incoming to ASA Inside interface to another device like wireshark or else.

Anyone have experienced about this?

Thank you.

Hi @CiscoJane,

It is not possible to mirror port on ASA device, like you can do it on switch. It was possible on smaller models (ASA5505, ASA5506) which had integrated switch. Above these platforms, devices do not have integrated switch, thus port mirroring is not possible.

You could mirror port or VLAN on a switch before/after FW, and basically achieve the same.

Kind regards,

Milos
