MONITOR SESSION mode
flow-based enable
2 Dene IP access-list rules that include the keyword monitor. For port monitoring, Dell Networking OS only considers trac 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.

Remote Port Mirroring
While local port monitoring allows you to monitor trac from one or more source ports by directing it to a destination port on the same
switch/router, remote port mirroring allows you to monitor Layer 2 and Layer 3 ingress and/or egress trac on multiple source ports on
dierent switches and forward the mirrored trac to multiple destination ports on dierent switches.
Remote port mirroring helps network administrators monitor and analyze trac to troubleshoot network problems in a time-saving and
ecient way.
