Port Mirroring
Port mirroring allows network traffic monitoring by copying each incoming and outgoing packet from
one port, called the
monitored port,
to another port, called the
monitoring port
. The packets can then be
analyzed from the monitoring port.
Supermicro switches support
•
only one session of port mirroring at a time
•
N:1 source:destination mirroring, i.e. multiple
source ports
can be mirrored by one destination
port.
Follow the steps below to configure port mirroring.
