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 source—port 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.
MONITOR SESSION mode
ip access-group access-list-name
To view an access-list that you applied to an interface, use the show ip accounting access-list command from EXEC Privilege
mode.

Configuring IPv6 Flow-Based Mirroring
This section describes how to configure IPv6 flow-based mirroring in the monitor session.
You can configure IPv6 flow-based mirroring under monitor session. The IPv6 flow-based mirroring is supported in SPAN, RSPAN,
and ERSPAN monitor sessions. By default, all mirror ACLs is considered as implicit permit. . The Dell EMC Networking OS creates a new
dedicated CAM region ipv6mirracl for IPv6 mirror ACL, which does not have any impact on IPv6 user ACL. The IPv6 mirror ACL
