Port Monitoring
The port monitoring feature allows you to monitor network traffic by forwarding a copy of each incoming or outgoing packet
from one port to another port.
Important Points to Remember
● Port monitoring is supported on physical ports and logical interfaces, such as port channels and virtual local area networks
(VLANs).
● The monitoring (destination, “MG”) and monitored (source, “MD”) ports must be on the same switch.
● In general, a monitoring port should have no ip address and no shutdown as the only configuration; Dell EMC
Networking OS permits a limited set of commands for monitoring ports; display them using the ? command. A monitoring
port also may not be a member of a VLAN.
● A total of 4 MG may be configured in a single port-pipe.
● MG and MD ports can be reside anywhere across a port-pipe.
● The Dell EMC Networking OS supports multiple source ports to be monitored by a single destination port in one monitor
session.
● One monitor session can have only one MG port.
NOTE: The monitoring port should not be a part of any other configuration.
