INTRODUCTION

Product Description


The AR211 is an Asymmetric Digital Subscriber Line (ADSL) Router for home or small office network connectivity to an Internet service provider over the Asynchronous Transfer Mode (ATM) network protocol.

ATM is a protocol that divides packets into small fixed sized cells for rapid transmission over high-speed networks. The ATM protocol allows various types (e.g. data, voice, and video) of traffic to be securely and efficiently carried over the same network.

This device provides a perfect solution to connect a small group of Internet users to high-speed network via the existing twisted pair telephone line.

A 10-BaseT port is provided for connection to an Ethernet LAN or Ethernet-equipped PC, and an ADSL port for connecting to your ADSL service provider to get on the Internet.



The console port provides an easy-to-setup configuration and software updating.

Configuration


There are three ways to configure this AR211, namely:

  1. Web configuration via an Ethernet connection.

  2. Terminal commands via

A: Telnet access by an Ethernet connection.

B: Any Terminal Emulation program by a RS232 serial cable connection.



Note: When the AR211 router is configured through an Ethernet connection,make sure the host PC must be set on the IP subnetwork that can be accessed by the router. For example, when the default network address of router Ethernet interface is 10.10.1.x,if the host PC is also set at 10.10.1.x, then host PC will have no problem communicate with ADSL Router via Ethernet network.

HTTP Web Configuration


The web configuration interface provides an easy-to-use user interface for router configuration. All the router configuration can be done through this interface.

  1. Start your favorite web browser (i.e. Netscape 4.0 or Explore 4.0 higher)

  2. Enter the AR211 ADSL router Ethernet IP address (e.g. 10.10.1.10) in the web page address.

  3. When the AR211 configuration utility prompts you to enter the user name and password, enter the default value root for both.



  1. After the router web server authenticates the username and password, the following web page will appear.

This Web-based configuration provides a menu-driven utility for you to configure and manage the AR211 through the most HTML browser.

In its home page, the Quick Setup covering four supported protocols RFC1483 Bridge, RFC1483 Router, IP over ATM (RFC1577), and PPP over ATM (RFC2364) lets you configure the AR211 effortlessly.

On the left navigation pane where bookmarks are provided to link you to the representative items to set up appropriate parameters, you can select Basic Setup to set up password, DHCP and DNS, NAT, and Virtual Server Mapping

For advanced function, move to Advanced Setup to set up E-mailing Sharing, Static Route, RIP, SNMP Community, SNMP Trap.

Click each field to expand in the navigation pane. The fields covered in this utility are described in the following section titled “Setting functions”.

To activate any new configuration, remember you have to click "Save" button to save the new data into the flash memory; and click "Reboot" to reboot the system immediately. Make sure you save all your changes into the flash before you reboot. After the system is rebooted, click the "refresh" button on your browser to re-access the web page.


Setting Functions

Basic Setup

Password


The default password required is test. It is recommended that you change the default password to a new one for management security.

DHCP and DNS


DHCP (Dynamic Host Configuration Protocols) offers the advantage of automatic network setup configuration. It’s a TCP/IP protocol that enables PC and workstations to get IP address from a centrally-administered server. When DHCP server function is enabled, it automatically assigns IP address to your host PC when the DHCP client function on your host PC is enabled .

DNS (Domain Name Service Server) is a server which translates Internet domain names into IP addresses. AR211 provids the DNS Proxy function that allows your host PC to use the ADSL Router as the default DNS server. This eases the administration effort when ISP’s DNS server IP address changes.


NAT


NAT is an Internet standard that enables a local area network (LAN) to use one set of local IP address for internal traffic and another set of global IP address for external traffic.

Virtual Server Mapping


In Internet Route connection, computers outside the Intranet are allowed to access specific network services inside the local Intranet by using the Virtual Server Mapping function. From the Virtual Server Mapping, you can set specific IP addresses as local servers which allows requests from outside users.

Advanced Setup

E-Mail Sharing


By taking advantages of the POP3, SMTP and dispatching-mails technologies, this E-mail Sharing function enables companies to share one public Internet email account for multiple internal users. Two modes are deployed as explained below.

Dispatch (Local): (with local email server inside the intranet)



Filter (Virtual): (no internal mail server)




Static Route


You can set a static route to manually administrate the network topology/traffic when dynamic routing is not effective enough.

RIP


Routing Information Protocol is employed to maintain a routing table.

SNMP Community


SNMP (Simple Network Management Protocol) is the most commonly used protocol for network management. For SNMP, network management station can query a management agent using a supported MIB (Management Information Base). In the AR211 SNMP Community Pool, you can assign community names and access authority (Read-only or Read-Write) for up to five SNMP Community.

SNMP Trap


. SNMP Trap is used when SNMP agent report unsolicited event notification message to the SNMP manager. In order for SNMP manager program to receive the traps, the IP address of SNMP management station has to be given to the SNMP agent.

Utility

Software Upgrade


Users can upgrade the software by activating the TFTP Server on the net to acquire the latest software and upgrade the AR211. For details, refer to the later chapter titled “Software Upgrade”.

Monitor

Routing Table


A routing table is a table that keeps tracks of routers to particular network destinations. To make sure all the packets can arrive at the destinations without errors, a routing table is established and maintained via which accurate routing database are provided for the router.

Setting up for Bridge Mode via Terminal Commands


The AR211 supports two kinds of Internet connection modes, i.e. Bridge Mode and Router mode.

When the AR211 operates in bridge mode, it behaves like a wire connecting a local PC directly to a service provider’s network. The Bridges simply forward data packets by recognizing the MAC layer addresses of devices on network.

While Routers forward data packets based on IP addresses. Router can also restrict types of data packets to be transmitted through your LAN from WAN.

Step-by-Step Configuration for Bridge Mode


Note the AR211’s factory default setting is set to Bridge Mode. So if it is used as a Bridge, the only things that need to be set are VC (VPI & VCI) , ATM Encapsulation Mode (LLC or VC Mux) and Bridge IP Address.The AR211 ADSL Router provides Bridging function that forwards data packets between LAN segments by recognizing the MAC addresses of each connected device. The AR211 ADSL router is acting like a hub that connects 2 LANs. The following figure demonstrates a typical bridging environment (Cisco 6400 - ATM router, Cisco 6260 - DSLAM), ADSL attributes Ethernet over ATM and LLC encapsulation, with configuration of VPI set at 0,and VCI 33.

At the command prompt, enter the following configuration.



  1. After connected, enter the user mane and password to get into the User mode. In the User mode, you can select to shift to Root mode by selecting su followed by the password (”root”). In the the Root mode you can configure your system.

Setting up for Router Mode via Terminal Commands


A router creates or maintains a table of the available routes and their conditions. With the information along with distance and cost algorithms routers determine the best route for any given packets. Typically, a packet may travel through a number of network points with routers before arriving at its destination.

A Router provides IP routing between a LAN (Local Area Network) and WAN (Wide Area Network) and is capable of configuring multiple encapsulation:



Ethernet over ATM (RFC1483)

IP over ATM (RFC1577)

IP over ATM is widely deployed by a number of different ATM providers. It can be used only in conjunction with a TCP/IP protocol stack, which must also be configured within the machine.



PPP over ATM (RFC2364)

When the router is configured to use PPP over ATM, the router ATM interface will request a PPP connection after the ADSL physical interface is established. If the PPP server is up and running on the CO/DSLAM side, ADSL router can log in and receive an IP address. AR211 currently support the following PPP authentication mothods : PAP, CHAP and MSCHAPv1.
