Port Mirror
Introduction
Port-based Mirroring
The Port-Based Mirroring is used on a network switch to send a copy of network packets sent/
received on one or a range of switch ports to a network monitoring connection on another switch
port (Monitor to Port). This is commonly used for network appliances that require monitoring of
network traffic, such as an intrusion-detection system.
Port Mirroring, together with a network traffic analyzer, helps to monitor network traffic. Users can
monitor the selected ports (Source Ports) for egress and/or ingress packets.
Source Mode:
Ingress
: The received packets will be copied to the monitor port.
Egress
: The transmitted packets will be copied to the monitor port.
Both
: The received and transmitted packets will be copied to the monitor port.
Note:
» The monitor port cannot be a trunk member port.
» The monitor port cannot be ingress or egress port.
» If the Port Mirror function is enabled, the Monitor-to Port can receive mirrored packets only.
» If a port has been configured as a source port and then user configures the port as a
destination port, the port will be removed from the source ports automatically.
