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.
