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
