Port Mirror

The Port Mirror function can be used to monitor data being transmitted through a specific port. This is done

by setting up another port (the mirror port) to receive the same data being transmitted from, or both to and

from, the port under observation. Using a mirror port allows the network administrator to sniff the observed

port to keep tabs on network activity.

Using Virtual LAN

Setting up Virtual LANs (VLANs) on your Moxa industrial secure router increases the efficiency of your network

by dividing the LAN into logical segments, as opposed to physical segments. In general, VLANs are easier to

manage.

The VLAN Concept

What is a VLAN?

A VLAN is a group of devices that can be located anywhere on a network, but which communicate as if they are

on the same physical segment. With VLANs, you can segment your network without being restricted by physical

connections—a limitation of traditional network design. With VLANs you can segment your network into:

• Departmental groups—you could have one VLAN for the marketing department, another for the finance

department, and another for the product development department.

• Hierarchical groups—you could have one VLAN for directors, another for managers, and another for

general staff.

• Usage groups—you could have one VLAN for email users and another for multimedia users.
