flow-based enable
2 Dene access-list rules that include the keyword monitor. Dell Networking OS only considers port monitoring trac that matches
rules with the keyword monitor.
CONFIGURATION mode
ip access-list
For more information, see 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.
