Because VLANs are based on logical instead of physical connections, it is very flexible for user/host management, bandwidth allocation and resource optimization.
1. Port-Based VLAN: each physical switch port is configured with an access list specifying membership in a set of VLANs.
2. ATM VLAN - using LAN Emulation (LANE) protocol to map Ethernet packets into ATM cells and deliver them to their destination by converting an Ethernet MAC address into an ATM address. The key for the IEEE 802.1Q to perform the above functions is in its tags.
802.1Q-compliant switch ports can be configured to transmit tagged or untagged frames. A tag field containing VLAN (and/or 802.1p priority) information can be inserted into an Ethernet frame. If a port has an 802.1Q-compliant device attached (such as another switch), these tagged frames can carry VLAN membership information between switches, thus letting a VLAN span multiple switches. However, it is important to ensure ports with non-802.1Q-compliant

GO-DSL-N150 User Manual
devices attached are configured to transmit untagged frames. Many NICs for PCs and printers are not 802.1Q-compliant. If they receive a tagged frame, they will not understand the VLAN tag and will drop the frame. Also, the maximum legal Ethernet frame size for tagged frames was increased in 802.1Q (and its companion, 802.3ac) from 1,518 to 1,522 bytes. This could cause network interface cards and older switches to drop tagged frames as "oversized."
PVID( Port VLAN ID) Each physical port has a default VID called PVID (Port VID). PVID is assigned to untagged frames or priority tagged frames (frames with null (0) VID) received on this port.
ADSL
The ADSL feature can be selected when you meet the physical connection problem. Please check the proper settings with your Internet service provider.
ADSL Mode Select the ADSL operation mode which your ADSL connection uses.
ADSL T ype Select the ADSL operation type which your ADSL connection uses.

3.8.4 Access Management

Choose Help > Access Management, the page shown in the following figure appears. This page that is displayed contains ACL, IP Filter, SNMP, UPNP and
DDNS.
ACL
You may use telnet or Web to remotely manage the ADSL Router. User just needs to enable Telnet or Web and give it an IP address that want to access the ADSL Router. The default IP 0.0.0.0 allows any client to use this service to remotely manage the ADSL Router.

GO-DSL-N150 User Manual
IP Filter
Select Telnet, FTP, TFTP, Web, SNMP, Ping to block incoming WAN requests for the corresponding service(s).
SNMP
Simple Network Management Protocol is used for exchanging information between network devices. Get Community: Select to set the password for the incoming Get requests from the management station. Set Community: Select to set the password for incoming Set requests from the management station.
UPnP
UPnP (Universal Plug and Play) is a distributed, open networking standard that uses TCP/IP for simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a network, obtain an IP address, convey its capabilities and learn about other devices on the network. In turn, a device can leave a network smoothly and automatically when it is no longer in use. UPnP broadcasts are only allowed on the LAN. Auto-Configure: UPnP network devices can automatically configure network addressing, announce their presence in the network to other UPnP devices and enable exchange of simple product and service descriptions.
DDNS
The Dynamic Domain Name System lets you use a static host name with a dynamic IP address. User should type the host name, user name and password assigned to your ADSL Router by your Dynamic DNS provider. User also can decide to turn on DYNDNS Wildcard or not.

3.8.5 Maintenance

Choose Help > Maintenance, the page shown in the following figure appears. This page that is displayed contains Administration, Time Zone, Firmware, SysRestart and Diagnostics.

Administration
There is only one account that can access Web-Management interface. It is admin. Admin has read/write access privilege. In this web page, you can set new password for admin.
Time Zone
The system time is the time used by the device for scheduling services. You can manually set the time or connect to a NTP (Network Time Protocol) server. If a NTP server is set, you will only need to set the time zone. If you manually set the time, you may also set Daylight Saving dates and the system time will automatically adjust on those dates.
Firmware
You can upgrade the firmware of the Router in this page. Make sure the firmware you want to use is on the local hard drive of the computer. Click on Browse to browse the local hard drive and locate the firmware to be used for upgrade.
SysRestart
User can restart the device with current settings or factory default settings.
Diagnostics
The Diagnostic Test page shows the test results for the connectivity of the physical layer and protocol layer for both LAN and WAN sides.

3.8.6 Status

Choose Help > Status, the page shown in the following figure appears. This page that is displayed contains Device Info, System Log and Statistics.
Device Info
This page displays the current information for the ADSL Router. It will display the Firmware version, LAN, WAN and MAC address information.

GO-DSL-N150 User Manual
System Log
The ADSL Router keeps a running log of events and activities occurring on the Router. If the device is rebooted, the logs are automatically cleared.
Statistics
The ADSL Router keeps statistic of traffic that passes through it. You are able to view the amount of packets that pass through the Router on both the WAN port and the LAN port. The traffic counter will reset if the device is rebooted. You can select Ethernet/ADSL to view the statistics report of LAN/WAN.
Statistics :: ADSL
Line State: This field displays the ADSL connection process and status. Modulation: This field displays the ADSL modulation status for G.dmt or T1.413. Annex Mode: This field displays the ADSL annex modes for Annex A or Annex B. Max Tx Power: This field displays the transmit output power level of the ADSL
Router. SNR Margin: Amount of increased noise that can be tolerated while maintaining the designed BER (bit error rate). The SNR Margin is set by Central Office DSLAM. If the SNR Margin is increased, bit error rate performance will improve, but the data rate will decrease. Conversely, if the SNR Margin is decreased, bit error rate performance will decrease, but the data rate will increase. Line Attenuation: Attenuation is the decrease in magnitude of the ADSL line signal between the transmitter (Central Office DSLAM) and the receiver (Client ADSL Modem), measured in dB. It is measured by calculating the difference in dB between the signal power level received at the Client ADSL Router and the reference signal power level transmitted from the Central Office DSLAM. Data Rate: This field displays the ADSL data rate.
