We found this command on enterprise switches tha allow you to send an aseptic copy of the traffic passing on a switch port. You can receive this “debug copy” on a passive port or remotely to a network analyzer

A network administrator configures the port mirror in many situations, including:

  • Troubleshooting network issues
  • Passive network probing
  • Intrusion detection system
  • MPLS tuning
