| Configuring the WSM using Device Manager |

Port Mirroring lets you gather information about network performance and usage from a monitor port with an attached network analyzer. When Port Mirroring is enabled, the target port's network packets (sent and/or received) are duplicated and sent to the monitor port for analysis.
In the figure below, a network analyzer is attached to port 5. Port 5 is monitoring both port 1 (ingress traffic, or traffic entering the WSM) and port 3 (egress traffic, or traffic leaving the WSM).
The WSM supports a single port monitoring one or more mirrored ports; but it does not support multiple ports monitoring a single mirrored port.
In the WSM, packets are duplicated and sent to the mirrored ports after client or server port processing (Layer 4 - 7) is completed. Data packets sent from a client to a virtual server are seen at the mirrored port as follows:
The response from the server to the client, however, is seen as follows:
