Factory Reset

Firmware> Configuration Backup Page

You can backup the system and switch settings to your workstation.

This can help you to reconfigure the

switch quickly if you have to re-set to factory defaults.

Additionally, if you want to try out different

configurations on the switch, this feature will enable you to quickly return to a previous configuration.

If you own several switches and you want them to have the same configuration, you can use this feature to

duplicate the settings to each switch.

Saving your Backup file:

•

Click Backup to store the current setting to a file in your PC.

•

Follow the instructions on the screen to select where you want to store your Backup file.

Restoring your Backup file (or using a duplicate configuration):

•

Click Restore to recover the Backup file from your PC to the current switch. If you do not want to

type in the path name, click Browse to find the Backup file.

•

Click OK in the File Download dialog box.

•

When download process is finished, click OK to confirm disconnection of current browser

connection.

CHAPTER 4: Software Upgrade Procedure

The application software for the Smart Switch is upgradeable, enabling your switch to take advantage of

improvements and additional features as they become available. The upgrade procedure and the required

equipment are described in the following section.

The upgrade procedure is as follows:

1.

Save the new firmware to your computer.

2.

Start the Smartwizard Discovery utility program.

3.

Select your switch by clicking on it.

4.

Then click on Firmware Upgrade, as highlighted in Figure 3-1.

Figure 3-1. Select the switch you want to upgrade and click Firmware Upgrade.

Figure 3-2. Locate New Firmware.

5.

Enter the location of the new firmware in the Firmware path below Firmware setting. Alternatively,

you can click Browse to locate the file. See Figure 3-2.

6.

Click Start to download the new firmware file in non-volatile memory.

Note:

Once the system finishes firmware upgrade process, the switch will automatically reboot.

The

Smartwizard Discovery utility will determine success of upgrade process based on the success of the

system reboot.

APPENDIX B: IEEE 802.1Q VLAN

A Local Area Network (LAN) can generally be defined as a broadcast domain. Hubs, bridges or switches in

the same physical segment or segments connect all end node switches. End nodes can communicate with

each other without the need for a

router

.

Routers connect LANs together, routing the traffic to appropriate

port.

A virtual LAN (VLAN) is a local-area network with a definition that maps workstations on some other basis

than geographic location (for example, by department, type of user, or primary application).

To

communicate between VLANs, traffic must go through a router, just as if they were on two separate LANs.

A VLAN is a group of PCs, servers and other network resources that behave as if they were connected to a

single, network segment — even though they may not be. For example, all marketing personnel may be

spread throughout a building. Yet if they are all assigned to a single VLAN, they can share resources and

bandwidth as if they were connected to the same segment. The resources of other departments can be

invisible to the marketing VLAN members, accessible to all, or accessible only to specified individuals,

depending on how the IT manager has set up the VLANs.

The Advantages of VLANs

Easy to do network segmentation

Users communicate most frequently with each other can be grouped into common VLANs, regardless of

physical location. Each group's traffic is largely contained within the VLAN, reducing extraneous traffic and

improving the efficiency of the whole network.

Easy to manage

The addition of nodes, as well as moves and other changes can be dealt with quickly and conveniently

from a management interface rather than the wiring closet.

Increased performance

VLANs free up bandwidth by limiting node-to-node and broadcast traffic throughout the network.

Enhanced network security

VLANs create virtual boundaries that can only be crossed through a router. So standard, router-based

security measures can be used to restrict access to each VLAN

IEEE 802.1Q VLANs

Packets received by the switch will be treated in the following way:

o

When an untagged packet enters a port, it will be automatically tagged with the port’s default VLAN

ID tag number. Each port has a default VLAN ID setting that is user configurable (the default setting

is 1). The default VLAN ID setting for each port can be changed in PVID Setting page.

o

When a tagged packet enters a port, the tag for that packet will be unaffected by the default VLAN

ID Setting.

o

The packet will now proceed to the VLAN specified by its VLAN ID tag number.

o

If the port in which the packet entered does not have membership with the VLAN specified by the

VLAN ID tag, the packet will be dropped.

o

If the port has membership to the VLAN specified by the packet’s VLAN ID, the packet will be able

to be sent to other ports with the same VLAN ID membership.
