Port Monitoring
Overview
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 only. Logical interfaces, such as Port Channels and
virtual local are networks (VLANs), are not supported.
• The Dell Force10 operating software (FTOS) supports as many monitor sessions on a system as
the number of port-pipes.
• The monitoring (destination, “MG”) and monitored (source, “MD”) ports must be on the same
switch.
• A monitoring port can monitor any physical port in the chassis.
• Only one MG and one MD may be in a single port-pipe.
• A monitoring port can monitor more than one port.
• More than one monitored port can have the same destination monitoring port.
• FTOS 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.
