Enabling Flow-Based Monitoring
Flow-based monitoring is supported on the platform.
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.
1 Enable flow-based monitoring for a monitoring session.
MONITOR SESSION mode
flow-based enable
2 Define access-list rules that include the keyword monitor. Dell Networking OS only considers port monitoring traffic that matches
rules with the keyword monitor.
CONFIGURATION mode
ip access-list
For more information, see Access Control Lists (ACLs).
