Moxa EDS-518E-4GTXSFP-T [51/116] The virtual lan vlan concept

Managed Ethernet Switch (UI_2.0_FW_5.x) Featured Functions

3-38

Monitoring Configuration

Refresh Rate

Setting Description Factory Default

5 to 300 If the Refresh Rate = T, then the PoE Port Status will be

refreshed every T seconds.

System Power Status

System Power Status shows a graph of Sum of measured power, Sum of allocated power, and Max of

allocated power. “Sum of measured power” (in green) shows the total measured power of all PDs, “Sum of

allocated power” (in blue) shows the total allocated power, and “Max of allocated power” (in red) shows the

threshold of total PoE power output. The graphs show Current (mA) versus Sec. (second), and are refreshed

at the configured Refresh Rate.

VLAN

Setting up Virtual LANs (VLANs) on your Moxa switch 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 Virtual LAN (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.
