Hey,

 

port-mirror is a global entity defining what to do with traffic requested to be mirrored (via firewall filter).

If you need more granularity, you can define number of "local" entities having completely unique configuration and tied them with specific FPCs (this traffic is mirrorred to this instance/port but this traffic is mirrored to that instance/port).
