Port mirroring allows you to duplicate the packets passing specified ports to the
destination mirroring port. As destination mirroring ports usually have data
monitoring devices connected to them, you can analyze the packets duplicated to
the destination mirroring port on these devices so as to monitor and troubleshoot
the network.
Figure 89 A port mirroring implementation
Local port mirroring is implemented through local port mirroring groups.
In a local port mirroring group, the source ports and the destination port are in the
same local port mirroring group. Packets passing through the source ports are
duplicated and then are forwarded to the destination port.
