The show config command has been modified to display monitoring configuration in a particular session.
Example Output of the show Command
(conf-mon-sess-11)#show config
!
monitor session 11
flow-based enable

The show ip accounting commands have been enhanced to display whether monitoring is enabled for traffic that matches
with the rules of the specific ACL.
Example Output of the show Command
DellEMC# show ip accounting access-list
!
Extended Ingress IP access list kar on TenGigabitEthernet 1/1/1/1
Total cam count 1
seq 5 permit ip 192.168.20.0/24 173.168.20.0/24 monitor
DellEMC#show ipv6 accounting access-list
!
Ingress IPv6 access list kar on TenGigabitEthernet 1/1/1/1
Total cam count 1
seq 5 permit ipv6 22::/24 33::/24 monitor
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 3 ingress traffic. You can specify traffic
using standard or extended access-lists.
NOTE: Flow-based monitoring is supported for known unicast egress traffic.
1. Create a monitoring session.
CONFIGURATION mode
monitor session session-id
2. Enable flow-based monitoring for a monitoring session.
MONITOR SESSION mode
flow-based enable
3. Specify the source and destination port and direction of traffic.
MONITOR SESSION mode
source sourceport destination destination-port direction rx
4. Define IP access-list rules that include the monitor keyword. For port monitoring, Dell EMC Networking OS only considers
traffic matching rules with the monitor keyword.
CONFIGURATION mode
ip access-list
To define access lists, see the Access Control Lists (ACLs) chapter.
5. Allocate a CAM region so that you can apply the ACL you created to the monitoring session.
CONFIGURATION mode
cam-acl l2acl number ipv4acl number ipv6acl number ipv4qos number l2qos number l2pt
number ipmacacl number vman-qos number ipv4mirracl number
6. Apply the ACL to the monitored port.
