In the following example, the host and server are exchanging traffic which passes through the uplink interface
1/1. Port 1/1 is the monitored port and port 1/42 is the destination port, which is configured to only monitor
traffic received on tengigabitethernet 1/1 (host-originated traffic).

Enabling Flow-Based Monitoring
Flow-based monitoring conserves bandwidth by monitoring only specified traffic instead of all traffic on the
interface. This feature is particularly useful when looking for malicious traffic. It is available for Layer 2 and
Layer 3 ingress and egress traffic. You can specify traffic using standard or extended access-lists.
