Hi,
If, i do port mirroring and then dump logs to packetbeat. Will i, be able to preserbe the client\_ip of the mirrored port.
Wanted to know about the outcome before trying it on my own.

Since you are receiving a copy of the packets when using a port mirror, the packets will their original `client_ip` and `ip` (and all other data). If your mirror port includes any VLAN encapsulation in the packets then make sure to set `with_vlan: true` in your interfaces configuration.
