3.2.8 Mirroring
Port Mirroring is used on a network switch to send a copy of network packets
seen on one switch port (or an entire VLAN) to a network monitoring connection
on another switch port. This is commonly used for network appliances that
require monitoring of network traffic, such as an intrusion-detection system.
3.2.8.1 Mirroring Configuration
• Port to Mirror to: The port that will “duplicate” or “mirror” the traffic on the
source port. Only incoming packets can be mirrored. Packets will be dropped
when the available egress bandwidth is less than ingress bandwidth.
• Ports to Mirror: Select the ports that you want to mirror from this section of the
page. A port will be mirrored when the “Mirroring Enabled” check-box is
checked.
