Port Mirroring
Port Mirroring copies all received and transmitted packets (including local traffic)
from a source port to a predefined destination port, in addition to the normal
destination port of the packets. The source and destination ports must be located in
the same DomainX.
For more information, refer to Port Mirroring in The Reference Guide.
This section explains how to configure a device’s ports to use Port Mirroring, and
includes:
•
Accessing Port Mirroring - Describes how to access the Port Mirroring dialog
box.
• Enabling Port Mirroring - Describes how to enable and define source and
destination modules and ports.
• Disabling Port Mirroring - Describes how to disable port mirrors.
Note: Port Mirroring is not permitted when there is no link on the destination
port.
Caution: Do not change the VLAN of the source or destination port while the port
mirroring mechanism is operating.
