1.1 Wireless Network

A wireless network is a flexible data communications system that extends the capability of the existing wired network to provide connectivity for wireless devices. Unlike the traditional wired network which relies on physical cables and wires to transmit and receive data, a wireless network relies on radio frequency (RF) technology to transmit and receive data.

A Wireless Access Point (AP) is a device that connects wireless communication devices. It is usually connected to a wired network on one end, and relays data to the wireless network on the other end.

The advent of the wireless network opens up the possibility of what a network infrastructure can be. Without the restriction of wires, the network can move with users and change as fast as the organization does. Figure 1.1 illustrates a sample wireless network.

Cedar 880AG Enterprise Dual-Radio AP/Bridge

Figure 1.1 Wireless Networks

1.2 Wireless LAN Bridge

Cedar Wireless Access Point provides the capability of being configured as a regular Access Point, a Wireless LAN Bridge or both. A Wireless LAN Bridge wirelessly connects two ore more Ethernet LANs together. It is a very practical, easy and in most cases inexpensive way to connect Ethernet LANs or extend the range of existing WLANs. As illustrated in Figure 1.2 and 1.3, the access point can operate in point-topoint or point-to-multipoint bridge topology.

Point-to-point

Point-to-point link allows you to use two access points to bridge two Local Area Networks from different locations. Access point A serves as a base bridge while Access point B serves as a non-base bridge. Both access points relay data between the two

Cedar 880AG Enterprise Dual-Radio AP/Bridge

networks. This is an ideal topology for connecting main office with warehouse, or between office buildings.

Figure 1.2 Point-to-Point Bridge

Point-to-Multipoint

Point-to-Multipoint Bridge allows you to use multiple access points to bridge Local Area Networks from different locations. Access point A serves as a base bridge while Access point B and C serve as non-base bridges. This is an ideal topology for central office to collect data from remote offices.

Figure 1.3 Point-to-Multipoint Bridge Mode

1.3 Access Point Deployment

The deployment of access point depends greatly on the building structure, the existing wiring and the type of service to be deployed. For example, RF signals transmit much easier through a wood-frame building than through a concrete one. For newly constructed

Cedar 880AG Enterprise Dual-Radio AP/Bridge

buildings where Ethernet cable CAT 5 is pre-installed, wiring is not a concern. For older construction, where re-cabling is cost prohibitive, a solution which is less dependent on wiring such as LAN Bridge may be more viable.

The access point coverage areas should overlap to ensure there are no gaps and roaming clients always have a connection available. In addition, the number of active wireless users and the type of service they are using (e.g. VoIP) are important factors to consider.

1.4 Application Deployment

Applications can be deployed easily after a network infrastructure is in place. Figure 1.3 illustrates a possible scenario:

• High Speed Internet Access is available for all wireless clients.

• Voice over IP applications can be used for calling over the Internet.

• Streaming media data can be offered over the IP network.

• Handheld devices for mobile staff can easily communicate with each other.

• All voice, video and data are transmitted seamlessly using QoS technology.

5 Network

This chapter contains information on the following topics:

• Change network settings

• Configure VLAN

• Configure DHCP Server

5.1 Overview

5.1.1 VLAN

Virtual LAN (VLAN) logically groups users by their functionality instead of physical location. VLAN uses software to configure logical topologies on top of the physical network infrastructure. Users grouped into one VLAN may be located on different floors or in different buildings. However, all users on one VLAN can communicate with each other as if they were all on the same physical LAN.

The same concept extends to a wireless network. Wireless clients can be grouped into wireless sub-networks. A client can access the network by connecting to an AP which supports its assigned VLAN (see Figure 5.1).

VLANs provide many benefits:

• VLANs increase performance by limiting broadcast traffic for both wired and

wireless networks.

• VLANs improve manageability by providing an easy, flexible way to modify logical

groups in changing environments. When a computer is physically moved to another location, it can stay on the same VLAN without any

• VLANs increase security options. Broadcast traffic is only broadcast within the

VLAN. This allows the network administrator to segment users requiring access to sensitive information into VLANs separate from the rest of the community.

Figure 5.1 VLANs

5.1.2 DHCP

Dynamic Host Configuration Protocol (DHCP) is a protocol for assigning dynamic IP addresses to computers on a network. Dynamic addressing simplifies network administration because the software keeps track of IP addresses. This means a new computer can be added to a network without the hassle of manually assigning it a unique IP address.

5.2 Web Interface

5.2.1 Network Setting

Select Network > IP to change network parameters.

Cedar 880AG Enterprise Dual-Radio AP/Bridge

Mode:

DHCP: If DHCP is chosen, a dynamic IP address is assigned to AP by the DHCP

Server. In addition, the subnet mask, default gateway and DNS server addresses are also assigned. Because DHCP assigns the IP address dynamically, different IP addresses may be assigned to the AP after each reboot.

Static: In order to have full control of the IP address, the administrator may choose to use the Static IP. If Static mode is chosen, the administrator assigns the static IP address, subnet mask, default gateway and DNS server address for the AP. The AP will always have the same IP address after each reboot.

IP address

For DHCP mode: The DHCP Server assigns a dynamic IP address to the AP. For Static mode: Enter the static IP address for the AP.

Netmask

For DHCP mode: The DHCP Server assigns a network mask to the AP. For Static mode: Enter the network mask for the AP.

Gateway

For DHCP mode: The DHCP Server assigns a default gateway to the AP. For Static mode: Enter the default gateway for the AP.

Management VLAN ID

By default, VLAN support is disabled. All packets sent by the AP are untagged. To enable VLAN support, click tagged and enter a VID value between 0 and 4095. Before enabling VLAN support, the VLAN setting needs to be pre-configured on a VLAN-aware switch, such as the Intelicis Cypress 1024.

Cedar 880AG Enterprise Dual-Radio AP/Bridge

Primary or Secondary DNS

Optionally enter the primary or secondary Domain Name Server (DNS) IP address. DNS translates domain names into IP addresses. Using DNS, network users are allowed to use more descriptive names such as www.example.com rather than

198.105.232.4.

5.2.2 VLAN

Select Network->VLAN to display the Virtual LANs in the system.

By default, VLAN support is disabled in Cedar. In this case, a single lan with the VLAN ID untagged is displayed.

6 Security

This chapter contains information on the following topics:

• Configure RADIUS profile

• Configure 802.1x authentication

• Configure MAC authentication

• Configure Filter to block certain traffic

6.1 Overview

6.1.1 802.1x Authentication

Wireless Networks provide enormous flexibility, but they can also create potential security problems in the network. Extensible Authentication Protocol (EAP) is an authentication method that addresses the security issues in the wireless network. It is part of the 802.1x WLAN standards defined by IEEE.

The IEEE 802.1x specification uses three important terms. The user or client who wants to be authenticated is called a supplicant. The actual server doing the authentication, typically a RADIUS server, is called the authentication server. And the device in between, such as a wireless access point, is called the authenticator. One of the key points of 802.1x is that the authenticator can be small and simple - all of the processing is done by the supplicant and the authentication server. This makes 802.1x ideal for wireless access points, which are typically small and have limited memory and processing power.

Figure 6.1 illustrates a simple 802.1x authentication sequence.

Cedar 880AG Enterprise Dual-Radio AP/Bridge

Figure 6.1 802.1x authentication sequence

1. The supplicant sends an authentication request containing identification and connection information to the authenticator.

2. The authenticator performs an initial negotiation with the supplicant to establish connection information (username, password, etc). The authenticator then forwards the user information in an authentication request to the RADIUS Server.

3. The RADIUS Server looks up the supplicant information in a local or remote RADIUS database.

4. If the information is found, the RADIUS server responds with a success message, which is then passed onto the supplicant. The authenticator now allows access to the network with possible restrictions based on attributes that came back from the authentication server. For example, the authenticator might switch the supplicant to a particular virtual LAN. If the information is not found, the RADIUS server responds with a reject message.

5. Based on the information it receives from the RADIUS server, the authenticator accepts or refuses the connection request.

6.1.2 MAC Authentication

Although 802.1x authentication addresses security issue for the wireless network, its implementation may not be practical for every wireless devices (e.g. PDA) because it requires supplicant software to be installed on all wireless client machines.

Cedar 880AG Enterprise Dual-Radio AP/Bridge

MAC authentication provides an alternative solution. It controls wireless access to the network by storing a list of MAC addresses on a local or RADIUS server. This list of MAC addresses identifies the authorized stations that may access the wireless network.

6.2 Web Interface

6.2.1 RADIUS Profile

RADIUS profile is used to store RADIUS server information. Select Security->RADIUS to list the available RADIUS profiles in the system. Click the existing profile name to enter the editing screen or click the Add button to create a new one.

Profile Name

Enter a descriptive name for the profile. The maximum length is 15.

RADIUS NAS IP

When the authenticator (AP) sends the user connection information (username, password, etc) to the RADIUS server, it also sends its IP as an authenticator identifier. The NAS (Network Access Server) IP is optional. When specified, it can be used to identify where the authentication request is being sent from.

RADIUS Failover Limit

Cedar first tries to use the primary RADIUS Server for authentication. If the primary RADIUS server is down, Cedar retries for a number of times. It then

Cedar 880AG Enterprise Dual-Radio AP/Bridge

switches to the secondary RADIUS server for authentication. The parameter specifies the number of retries. The default is 4.

Primary Auth Server Retry Period

7 Wireless

This chapter contains information on the following topics:

• Configure Wireless Setting

• Configure WLAN

• Configure Radio 1 and 2

• Configure Bridge Link

7.1 Overview

7.1.1 WLAN

Similar to the Virtual LAN concept, WLAN is a way to logically group wireless users into sub-networks. Each WLAN may implement a different security mechanism and has a different level of access to the network. The administrator can selectively enable a list of WLANs on the AP. A wireless user is allowed to access the wireless network by connecting to an AP which supports his assigned WLAN.

A RADIUS server can be used to enforce WLAN access control. When a wireless user connects to the AP using a WLAN, he may or may not be authorized to use that WLAN. During the authentication phase, the RADIUS server not only authenticates the user but also returns user attributes (e.g. the user’s VLAN ID) to the authenticator (AP). The AP can subsequently determine whether to allow the user access to the wireless network.

7.1.2 Bridge Link

Bridge Link is a cost effective way to connect Ethernet LANs from difference location using wireless devices. As described in Chapter 1, bridge link can work in a point-topoint or point-to-multipoint topology. You can use either topology to support:

z Single VLAN network: untagged packets are sent across the wireless bridge link. z Multiple VLANs network: tagged packets are sent across the wireless bridge link.

Figure 7.1 illustrates a point-to-point bridge link topology supporting multiple VLANs network.

Wireless clients will establish association with the access point using the Open mode and no encryption implementation.

Using 802.1x Authentication

A wireless client will authenticate himself via RADIUS Server before using the wireless network. The administrator must configure a RADIUS profile which contains the RADIUS location and password information, as well as an 802.1x

Cedar 880AG Enterprise Dual-Radio AP/Bridge

profile which contains 802.1x specific information. The administrator may select one, two or all three of the association mode and encryption method combinations listed below:

• Dynamic WEP with 802.1x authentication

o association mode is Open o encryption method is Dynamic WEP

• WPA/TKIP with 802.1x authentication

o association mode is Wi-Fi Alliance’s WPA o encryption method is TKIP

• WPA2/AES with 802.1x authentication

o association mode is Wi-Fi Alliance’s WPA2 o encryption method is AES

Using Key/Passphrase

The authentication mechanism used between wireless clients and the wireless network is a pre-configured key or passphrase. The key or passphrase configured on the client’s machine must match those stored on the AP. The administrator may choose one, two or all three of the association mode and encryption method combinations listed below:

• Static WEP key

o association mode is Open o data encryption method used is Static WEP key

You must choose a default WEP Key index and fill in the WEP key.

• WPA/TKIP with PSK

o association mode is Wi-Fi Alliance’s WPA o encryption method is TKIP.

You must fill in the WPA Pre-Shared-Key Passphrase.

• WPA2/AES with PSK

o association mode is Wi-Fi Alliance’s WPA2 o encryption method is AES

You must fill in the WPA2 Pre-Shared-Key Passphase.

MAC Auth

must choose a MAC authentication profile to be used for authentication.

• Off: (default) No MAC authentication is performed.

MAC Auth Profile

Cedar 880AG Enterprise Dual-Radio AP/Bridge

Specify the MAC authentication profile to be used for authentication. You must have already configured a MAC authentication profile in the system. If the MAC authentication method requires the RADIUS Server, you will also need to specify the RADIUS profile.

RADIUS Profile

Specify the RADIUS profile to be used for 802.1x or MAC authentication.

Forced Unicast Tx Rate

This parameter allows you to configure a transmission rate (in 100 kbps) that will be used for all unicast frames. The rate must be one of the AP’s supported rates.

Maximum Unicast Tx Rate

This parameter allows you to set a maximum limit on the transmission rate to be used. By default, this option is disabled, which allows any supported rate to be used.

Min Rate to Associate

This parameter allows you to set a minimum rate required for association. If a client station does not support any rates equal to or greater than this rate, the association will be rejected.

DTIM

The Delivery Traffic Indication Message (DTIM) is used by the AP to indicates which client station, currently sleeping in low-power mode, have data buffered on the access point waiting for pick-up. DTIM should be left at 2, the default value. This parameter supports a range between 1 and 255.

Maximum Stations

This parameter specifies the maximum number of stations which can associate with the AP. The default is 256.

7.2.3 Radio

Select Wireless->Radio 1 or Wireless->Radio 2 to display radio specific parameters for radio 1 or 2. Except for WLAN and Bridge Link, most of the parameters can be left with their default values.

Cedar 880AG Enterprise Dual-Radio AP/Bridge

802.11b and 802.11g devices.

• super-ag: Enabling Super AG provides better performance by increasing radio

throughput.

Channel

Select a channel for the AP. If auto is selected, the AP automatically chooses a relatively unused channel. The administrator can specify a list of “preferred” channels using Auto Channel List that you wish the AP to scan first. Channels not in the Auto Channel List will not be chosen by the AP. If the administrator wants to manually set the channel, he needs to ensure that nearby devices do not use the same channel.

If bridge link is configured, all bridge links need to communicate on the same channel.

Cedar 880AG Enterprise Dual-Radio AP/Bridge

• Auto: the default setting. It allows the AP to select a free or relatively unused

communication channel. Channels in the Auto Channel List are preferred channels and will be scanned first.

• 1-14: used for frequencies b, g, and bg

• 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 149, 153, 157,

161, 165: used for frequency a

• 40, 48, 56, 153, 161: used for frequency super-ag (radio 1)

• 6: used for frequency super-ag (radio 2)

) The channel regulation varies for every country. AP only allows you to set the

channel that is legal in your country.

Transmit Power

Under certain circumstances, you may want to reduce the transmit power. An example would be when two radios are transmitting and receiving on nearby channels. To prevent one radio from interfering with the other, you may want to reduce its power.

• Auto: the default setting

• 1-20 dbm

Mode

Select one of the operating modes for AP. The AP can operate as a regular AP, a Bridge or both.

AP: The AP operates as a regular access point. BRGLNK: The AP operates as a Bridge. AP, BRGLNK: The AP operates as both AP and Bridge.

Role

In a point-to-point or point-to-multipoint bridge link environment, one of the bridges has to be the base bridge. The rest of the bridges which associate with the base bridge become non-base bridges.

Base: The AP operates as a base bridge. Non-Base: The AP associates with the base bridge.

Repeater

A repeater is not connected to a wired LAN. When an AP is configured as a repeater, its Ethernet port does not function. It has to reply on other Bridge or AP to forward packets.

On: Enable repeater mode. Off: The default setting.

Link Distance

The typical distance between the wireless clients and AP is less than 1 kilometer (km). If your wireless network covers a bigger area, you may need to adjust this parameter. Increasing link distance automatically increases the packet acknowledge timeout period. This will impact the overall wireless network performance. The default setting is 0 (less than 1 km).

7.2.4 Bridge Link

A Bridge Link can greatly ease the difficulties involved in physically wiring LANs from different locations by connecting them wirelessly.

Select Wireless->Bridge Link to list the available Bridge Links in the system. Click the existing Bridge Link name to enter the editing screen or click the Add button to create a new one.

After a Bridge Link is created, add it to either one of the Radios in order for it to take effect.

) For performance reasons, it is recommended that the Bridge Link to be added

onto Radio 1. Radio 1 usually has less traffic and less interference.

) All Bridge Links must be configured to use the same radio channel. Auto

channeling is not allowed.

) On the Radio where the Bridge Link is being added, the security policy of the

primary (the first) WLAN must be WPA2/AES.

Make sure the signal quality of the Bridge Link is adequate because it greatly impacts the performance. Once a link is established, its signal quality and other statistics can be viewed by selecting Monitor->Wireless Link. Follow the steps below to improve the signal strength of the WDS link:

Cedar 880AG Enterprise Dual-Radio AP/Bridge

• The two APs should be placed such that there are minimal objects between

them. Any steel or wood objects absorb RF energy. You should also consider radio interference from devices such as microwave ovens or other APs.

• Scan the channel activities to select a channel that is least busy.

• Adjust the power level setting when the distance of the two APs changes; the

further the distance, the higher the power.

• Adjust the link distance parameter as you see fit.

Name

Enter a descriptive name for the Bridge Link. The maximum length is 7.

Link SSID

Enter the SSID to be used between the base and non-base bridges. Each bride link should have its own SSID configured.
