Enabling Flow-Based Monitoring
Flow-based monitoring is supported on the Z9000 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.
