Which technology permits you to monitor all traffic going out of a specific port by duplicating the traffic to a monitoring port?

Port mirroring is the technique that duplicates the traffic from a source port to a dedicated monitoring port, so a device connected to that monitoring port can see all frames leaving the source port. This exact setup lets you observe every bit of outbound traffic without interfering with the actual data path. Other options don’t fit: Port Security controls which devices can connect to a port, ACLs filter or permit traffic without duplicating it, and VLAN tagging simply adds VLAN IDs to frames for separation rather than providing a copy for analysis.
