4.4.4 QoS

QoS (Quality of Service). This option will provide better service of selected network traffic

over various technologies. Deploying QoS management to guarantee that all application

receive the service levels required and sufficient bandwidth to meet performance expectations

is indeed one important aspect of modem enterprise network.

4.4.5 VLAN

Virtual LAN (VLAN) is a group of devices on one or more LANs that are configured so

that they can communicate as if they were attached to the same wire, when in fact they are

located on a number of different LAN segments. 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 then 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 configure 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 devices attached are

configured to transmit untagged frames. Many NICs for PCs and printers are not

802.1Q-compliant. If they received a tagged frame, they will not understand the VLAN tab 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 1518 to 1522 bytes. This could cause

network interface cards and older switches to drop tagged frames as “oversized”

Assign VLAN PVID for each interface:

You can assign ATM VC, Ethernet (LAN) port, and

Wireless LAN port’s PVID in this section.

Î

Define VLAN Group:

Based on each VLAN group, you can configure each group’s VLAN

setting. You can configure up to 8 VLAN settings.

4.4.6 ADSL

Select this option to set ADSL Mode and ADSL Type information.

ADSL Mode:

You can set your

ADSL mode

in this section. The option has Auto Sync-up,

ADSL2+, ADSL2, G.DMT, T1.413, G.LITE

ADSL Type:

ANNEX A, ANNEX I, ANNEX A/L, ANNEX M, ANNEX A/I/J/L/M

4.5 Access Management

4.5.1 ACL

Go to

Access Management

Æ

ACL

to enable remote management. 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 wants 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.

ACL:

There has

Activated

&

Deactivated

option. The default setting is

Deactivated

which

means all IP can access via router. If you choose

Activated

, you only can access via router by

listed IP addresses.

ACL Rule Index:

Index number from 1 and up to 16.

Active:

Once you choose

Yes

then you can access the IP via router.

Application:

Each of these labels denotes a service that you may use to remotely manage the

Router. Choices are

Web, FTP, Telnet, SNMP, Ping, ALL

.

Interface:

Select the access interface. Choices are

WAN, LAN

and

Both.

For Example:

How to set your ACL?

1. You must choose

Activated

to enable your ACL function.

2.

Select the ACL Rule Index number (up to 16 number)

3.

You can set the specific

Secure IP address

or set

0.0.0.0

for all IPs.

4. Choose the

Application

which you want to access for this ACL Rule index.

5. Select the

Interface

you want to access from.

6.

After all settings are ready, click

SAVE

and continue next ACL Rule Index setting.

[Note]

1. You must set one ACL index to access your router via LAN interface. If you don’t, your

router cannot access other listed IP Address. (Refer to Index 1).

2. Remember! Once you active your ACL function, you only can access via router by

listed Secure IP Address.

4.5.2

IP Filter

The Router provides extensive firewall protection by restricting connection parameters

to limit the risk of intrusion and defending against a wide array of common hacker attackers.

Go to

Access Management

Æ

Filter

to set different IP filter rules of a given protocol (TCP,

UDP, or ICMP) and a specific direction (incoming, outgoing, or both) to filter the packets.

59

IP Filter is a more complex filtering tool, based more on IP and custom rules. Each of the

indices can hold six rules, and each interface can have four associated indices, allowing 24

Rate
