Port Mirroring
Port mirroring is used on switches to copy sent/received network packets from
one or more areas of network monitoring or to send them to another switch port
(monitor port).
Port mirroring is used in network systems that require monitoring of network
traffic as in an IDS (“
I
ntrusion
D
etection
S
ystem”).
Port mirroring, together with an NTA (“
N
etwork
T
raffic
A
nalyzer”) can help to
monitor network traffic. Users can monitor incoming and/or outgoing data packets
on selected ports (“Source Ports”).
Source Mode
•
“Ingress”:
The incoming data packets are copied and
forwarded to the monitor port.
•
“Egress”:
The outgoing data packets are copied and
forwarded to the monitor port.
•
Both:
Both incoming and outgoing data packets are
copied and forwarded to the monitor port.
1.
The monitor port cannot be a member of a “Truck Port” group.
2.
The monitor port cannot be an ingress or egress port.
3.
If a port has been configured as a source port and a user then
configures it as a destination port, the port is automatically deleted
from the source ports.

Duplex Mode
A duplex communication system is a system composed of two connected devices
that can communicate with each other in both directions.
Half-Duplex
A half-duplex system provides for communication in both directions, but only one
direction at a time (not simultaneously).
One device receives a signal and must wait for the other device to stop
transmitting before replying.
