Among the LPUs supported by S7900E switches, the SC, SD, and EB series LPUs support mirroring
incoming packets and outgoing packets; the SA and EA series LPUs only support mirroring incoming
packets.

Configuring Remote Traffic Mirroring

To implement remote traffic mirroring, perform the following configurations on the source device and
destination device:
Configurations on the source device
Traffic mirroring configuration: configure traffic mirroring on the source device to mirror packets
matching certain criteria to the port connecting to the destination device (assuming the port is Port
A). For the detailed configuration procedure, refer to
Remote source mirroring group configuration: configure a remote source mirroring group on the
source device, and configure the destination port in traffic mirroring (that is, Port A) as the egress
port. For the detailed configuration procedure, refer to
You should specify an arbitrary port as the mirroring port. To prevent packets received/sent by the port
from being mirrored to the destination device by the remote source mirroring group, you are
recommended to configure an unused port as the mirroring port.
