Port Mirroring - HP ProCurve 1810G Management And Configuration Manual

Port Mirroring

Port mirroring sends a copy of all packets sent and/or received on one port (the source port) to another
port (the destination port) for monitoring and analysis by an external network analyzer. Multiple switch
ports can be configured as source ports, with each port mirrored to the same destination. You can also
mirror the internal CPU traffic to an external port for debugging the CPU.

When configuring port mirroring, avoid oversubscribing the destination port to
prevent the loss of mirrored data.
While a port is used as the destination port for mirrored data, the port cannot be
used for any other purpose; the port will not receive and forward traffic.
