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.
1 Enable flow-based monitoring for a monitoring session.
MONITOR SESSION mode
flow-based enable
2 Define in access-list rules that include the keyword
monitor
. For port monitoring, Dell Networking OS
only considers traffic matching rules with the keyword
monitor
.
CONFIGURATION mode
ip access-list
Refer to Access Control Lists (ACLs) .
3 Apply the ACL to the monitored port.
INTERFACE mode
ip access-group access-list
Example of the
flow-based enable
Command
To view an access-list that you applied to an interface, use the
show ip accounting access-list
command from EXEC Privilege mode.
