The following table describes the labels in this screen.

LABEL

DESCRIPTION

ESSID

The ESSID (Extended Service Set Identification) is a unique name to identify the

BIPAC-5100/5100W in the wireless LAN. Wireless stations associating to the

BIPAC-5100/5100W must have the same ESSID.

Enter a descriptive name (up to 32 characters).

Hide ESSID

Select

Yes

to hide the ESSID in so a station cannot obtain the ESSID through passive

scanning.

Select

No

to make the ESSID visible so a station can obtain the ESSID through

passive scanning.

Channel ID

The range of radio frequencies used by IEEE 802.11b wireless devices is called a

channel.

Select a channel from the drop-down list box.

RTS/CTS

Threshold

The RTS (Request To Send) threshold (number of bytes) for enabling RTS/CTS

handshake. Data with its frame size larger than this value will perform the RTS/CTS

handshake. Setting this attribute to be larger than the maximum MSDU (MAC service

data unit) size turns off the RTS/CTS handshake. Setting this attribute to zero turns

on the RTS/CTS handshake.

Enter a value between 0 and 2432.

Fragmentation

The threshold (number of bytes) for the fragmentation boundary for directed

37

Threshold

messages. It is the maximum data fragment size that can be sent.

Enter a value between 256 and 2432.

WEP Encryption

WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the

wireless network.

Select

Disable

to allow all wireless computers to communicate with the access points

without any data encryption.

Select

64-bit WEP

or

128-bit WEP

to use data encryption.

Key 1 to Key 4

The WEP keys are used to encrypt data. Both the BIPAC-5100/5100W and the

wireless stations must use the same WEP key for data transmission.

If you chose

64-bit WEP

, then enter any 5 ASCII characters or 10 hexadecimal

characters ("0-9", "A-F").

If you chose

128-bit WEP

, then enter 13 ASCII characters or 26 hexadecimal

characters ("0-9", "A-F").

You must configure all four keys, but only one key can be activated at any one time.

The default key is key 1.

IP Address

Enter the IP address of your BIPAC-5100/5100W in dotted decimal notation, for

example, 192.168.1.254 (factory default).

IP Subnet Mask

Type the subnet mask assigned to you by your ISP (if given).

Multicast

IGMP (Internet Group Multicast Protocol) is a session-layer protocol used to establish

membership in a multicast group. The BIPAC-5100/5100W supports both IGMP

version 1 (

IGMP-v1

) and

IGMP-v2

. Select

None

to disable it.

5.5 Configuring MAC Filter

The MAC filter screen allows you to configure the BIPAC-5100/5100W to give exclusive

access to up to 32 devices (Allow Association) or exclude up to 32 devices from accessing the

BIPAC-5100/5100W (Deny Association). Every Ethernet device has a unique MAC (Media

Access Control) address. The MAC address is assigned at the factory and consists of six pairs

of hexadecimal characters, for example, 00:AA:BB:00:00:02. You need to know the MAC

address of the devices to configure this screen.

To change your BIPAC-5100/5100W’s MAC filter settings, click Wireless LAN, MAC Filter to

open the MAC Filter screen. The screen appears as shown.

are allowed or denied access to the BIPAC-5100/5100W in these address fields.

Chapter 6

WAN Setup

802.11b is only supported for the BIPAC-5100W

This chapter describes how to configure WAN settings.

6.1 WAN Overview

A WAN (Wide Area Network) is an outside connection to another network or the Internet.

See the Wizard Setup chapter for more information on the fields in the WAN screens.

6.2 PPPoE Encapsulation

The BIPAC-5100/5100W supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is

an IETF Draft standard (RFC 2516) specifying how a personal computer (PC) interacts with a

broadband modem (DSL, cable, wireless, etc.) connection. The PPPoE option is for a dial-up

connection using PPPoE.

For the service provider, PPPoE offers an access and authentication method that works with

existing access control systems (for example Radius). PPPoE provides a login and

authentication method that the existing Microsoft Dial-Up Networking software can activate,

and therefore requires no new learning or procedures for Windows users.

One of the benefits of PPPoE is the ability to let you access one of multiple network services, a

function known as dynamic service selection. This enables the service provider to easily

create and offer new IP services for individuals.

Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires

no specific configuration of the broadband modem at the customer site.

By implementing PPPoE directly on the BIPAC-5100/5100W (rather than individual computers),

the computers on the LAN do not need PPPoE software installed, since the

BIPAC-5100/5100W does that part of the task. Furthermore, with NAT, all of the LANs’

computers will have access.

6.3 PPTP Encapsulation

Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables secure transfer of

data from a remote client to a private server, creating a Virtual Private Network (VPN) using

TCP/IP-based networks.

PPTP supports on-demand, multi-protocol and virtual private networking over public networks,

such as the Internet.

6.4 Traffic Shaping

Traffic Shaping is an agreement between the carrier and the subscriber to regulate the

average rate and “burstiness” or fluctuation of data transmission over an ATM network. This

agreement helps eliminate congestion, which is important for transmission of real time data

such as audio and video connections.

Peak Cell Rate (PCR) is the maximum rate at which the sender can send cells. This parameter

may be lower (but not higher) than the maximum line speed. 1 ATM cell is 53 bytes (424 bits),

so a maximum speed of 1 Mbps gives a maximum PCR of 2415 cells/sec. This rate is not

guaranteed because it is dependent on the line speed.

Sustained Cell Rate (SCR) is the mean cell rate of a bursty, on-off traffic source that can be

sent at the peak rate, and a parameter for burst-type traffic. SCR may not be greater than the

PCR; the system default is 0 cells/sec.

Maximum Burst Size (MBS) is the maximum number of cells that can be sent at the PCR. After

MBS is reached, cell rates fall below SCR until cell rate averages to the SCR again. At this

time, more cells (up to the MBS) can be sent at the PCR again.

The following figure illustrates the relationship between PCR, SCR and MBS.
