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 Networking operating
software 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 can be configured in a single port-pipe.
• MG and MD ports can reside anywhere across a port-pipe.
• Dell Networking operating software 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.
