Mirror the switch ports, where traffic travels to and from the monitored servers, to the ports where Multi-Port Monitor is connected.
Application Delivery Analysis measures and analyzes only TCP network traffic. Therefore, sending additional traffic through the mirror port adds unnecessary load to the capture card on Multi-Port Monitor. In extreme cases, the unneeded data can cause packet loss. However, Multi-Port Monitor analyzes traffic composition and performance metrics from all active protocols on the network. Consider these valuable metrics, which are complementary to the TCP metrics of Application Delivery Analysis, when deciding which traffic is irrelevant.
Multi-Port Monitor provides a packet deduplication setting that applies to the capture card and is enabled by default. This setting discards packets deemed to be duplicates of packets already received and processed if they arrive within a few packets of each other.
During initial port mirroring configuration, you can temporarily disable the global setting for packet deduplication. Disabling the setting lets you see duplicate packets, which can help you eliminate duplication from mirrored sessions.
