Flow-based monitoring
Flow-based monitoring conserves bandwidth by inspecting only specified traffic instead of all interface traffic. Using flow-based
monitoring, you can monitor only traffic received by the source port that matches criteria in ingress access-lists (ACLs). IPv4 ACLs, IPv6
ACLs, and MAC ACLs support flow-based monitoring.
1. Enable flow-based monitoring for a monitoring session in MONITOR-SESSION mode.
flow-based enable
2. Return to CONFIGURATION mode.
