First-time Installation and Configuration

Before installing the AWK-6222, make sure that all items in the Package Checklist are in the box. In addition,

you will need access to a notebook computer or PC equipped with an Ethernet port. The AWK-6222 has a

default IP address that you must use when connecting to the device for the first time.

Step 1: Select the power source.

The AWK-6222 can be powered by DC power input or PoE (Power over Ethernet).

Step 2: Connect the AWK-6222 to a notebook or PC.

Since the AWK-6222 supports MDI/MDI-X auto-sensing, you can use either a straight-through cable or

crossover cable to connect the AWK-6222 to a computer. If the LED indicator on the AWK-6222’s LAN port

lights up, it means the connection is established.

Step 3: Set up the computer’s IP address.

Set an IP address on the same subnet as the AWK-6222. Since the AWK-6222’s default IP address is

192.168.127.253, and the subnet mask is 255.255.255.0, you should set the IP address of the computer to

192.168.127.xxx.

Step 4: Use the web-based manager to configure AWK-6222

Open your computer’s web browser and type in http://192.168.127.253 in the address field to access the

homepage of the web-based Network Manager. Before the homepage opens, you will need to enter the

username and password as shown in the following figure. For first-time configuration, enter the default

username and password and then click on the Login button:

u select Maintenance  Load Factory Default and click the Submit button, the AWK-6222 will

In the following sections we will describe two test methods that can be used to ensure that a network

connection has been established.

Communication Testing

After installation, you can run a sample test to make sure the AWK-6222 and wireless connection are

functioning normally. Two testing methods are explained in the following sections. Use the first method if you

are using only one AWK-6222 device, and use the second method if you are using two or more AWK-6222s.

Testing Method for One AWK-6222 with AP-Client Operation Mode

If you are only using one AWK-6222, you will need a second notebook computer equipped with a WLAN card.

Configure the WLAN card to connect to the AWK-6222 (NOTE: the default SSID is MOXA_1), and change the

IP address of the second notebook (B) so that it is on the same subnet as the first notebook (A), which is

connected to the AWK-6222.

AWK-6222 Getting Started

2-4

After configuring the WLAN card, establish a wireless connection with the AWK-6222 and open a DOS window

on Notebook B. At the prompt, type

ping <IP address of notebook A>

and then press Enter (see the figure below). A “Reply from IP address …” response means the communication

was successful. A “Request timed out.” response means the communication failed. In this case, check the

configuration to make sure the connections are correct.

Testing Method for Two or More AWK-6222s with AP-Client Operation Mode

If you have two or more AWK-6222s, you will need a second notebook computer (B) equipped with an Ethernet

port. Use the default settings for the first AWK-6222 connected to notebook A and change the second or third

AWK-6222 connected to notebook B to Client mode. Then, configure the notebooks and AWK-6222s as

illustrated below:

After setting up the testing environment, open a DOS window on notebook B. At the prompt, type

ping <IP address of notebook A>

and then press Enter. A “Reply from IP address …” response means the communication was successful. A

“Request timed out” response means the communication failed. In this case, recheck the configuration to make

sure the connections are correct.

Wireless Settings

The essential settings for wireless networks are presented in this function group. Settings must be properly set

before establishing your wireless network.

Operation Mode

The AWK-6222 supports three operation modes that are used for different wireless network applications:

Wireless Redundancy

In traditional architectures, most vendors only provide a single RF AP and Client, in which the AP connects one

or more Clients to the network. Since the AP and Client are connected by a single RF connection, if the RF

connection is disconnected the system or network behind the Client will be disconnected, too.

With the new wireless redundancy technology, you can set up a redundant wireless connection between a

redundant client device and a redundant AP device. The redundant structure involves using the

AWK-6222’s two RF modules to set up two independent wireless connections between the redundant client

and redundant AP devices. If either of the two wireless connections fails, the other wireless connection will

continue transmitting packets between the redundant client and redundant AP devices. In addition to

carrying one or more redundant clients, standard single RF clients can also associate with the redundant AP.

One of the biggest advantages of the AWK-6222’s wireless redundancy mode is that you can expect “zero data

loss.”

Wireless Bridge

A bridge is a network component that connects two networks. AWK-6222’s bridge operation is based on the AP

(master) and Client (Slave) concept. Both sides of the connection must have the same RF type, SSID, and

security settings.

For single RF mesh networks, we can use WDS to establish a static bridge link. In this case, the APs at both ends

of the WDS link must be configured manually with each other’s MAC addresses. The performance of a single RF

bridge will be poor if more nodes are added.

The AWK-6222’s dual RF bridge concept is different from using a single RF, because the AWK-6222 has dual

RFs, and offer users a cascade link to bridge the two ends without narrowing down the throughput.

WLAN Security Settings

The following figure shows the WLAN1/2 Security Settings page. The parameters and options are described

below:

The AWK-6222 provides four standardized wireless security modes: Open, WEP (Wired Equivalent Privacy),

WPA (Wi-Fi Protected Access) and WPA2. Several types of security models are available in AWK-6222 by

selecting Security mode and WPA type:

• Open: No authentication, no data encryption.

• WEP: Static WEP (Wired Equivalent Privacy) keys must be manually configured.

• WPA/WPA2-Personal: also known as WPA/WPA2-PSK. You need to specify the Pre-Shared Key in the

Passphrase field, which will be used by the TKIP or AES engine as a master key to generate keys that

actually encrypt outgoing packets and decrypt incoming packets.

• WPA/WPA2-Enterprise: also called WPA/WPA2-EAP (Extensible Authentication Protocol). In addition to

device-based authentication, WPA/WPA2-Enterprise enables user-based authentication via IEEE802.1X.

The AWK-6222 can support three EAP methods: EAP-TLS, EAP-TTLS, and EAP-PEAP.

Open

For security reasons, it is highly recommended that the security mode should be set to an option other than

Open System. When the security mode is set to Open System, no authentication or data encryption will be

performed.

WEP

According to the IEEE802.11 standard, WEP can be used for authentication and data encryption

(confidentiality). Shared (or Shared Key) authentication type is used if WEP authentication and data

encryption are both needed. Normally, Open (or Open System) authentication type is often used when WEP

data encryption is run with authentication.

When WEP is enabled as a security mode, the length of a key (so-called WEP seed) can be specified as 64/128

bits, which is actually a 40/104-bit secret key with a 24-bit initialization vector. The AWK-6222 provides 4

entities of WEP key settings that can be selected to use with Key index. The selected key setting specifies the

key to be used as a send-key for encrypting traffic from the AP side to the wireless client side. All 4 WEP keys

are used as receive-keys to decrypt traffic from the wireless client side to the AP side.

The WEP key can be presented in two Key type, HEX and ASCII. Each ASCII character has 8 bits, so a 40-bit

(or 64-bit) WEP key contains 5 characters, and a 104-bit (or 128-bit) key has 13 characters. In hex, each

character uses 4 bits, so a 40-bit key has 10 hex characters, and a 128-bit key has 26 characters.

WPA/WPA2-Personal

WPA (Wi-Fi Protected Access) and WPA2 are significantly improved encryption methods over WEP. WPA is a

security standard based on 802.11i draft 3, while WPA2 is based on the fully ratified version of 802.11i. The

initial vector is transmitted, encrypted, and enhanced with its 48 bits, twice as long as WEP. The key changes

regularly so that true session is secured.

Even though AES encryption is only included in the WPA2 standard, it is widely available in the WPA security

mode of some wireless APs and clients as well. The AWK-6222 also supports AES algorithms in WPA and WPA2

for better compatibility.

Personal versions of WPA/WPA2, also known as WPA/WPA-PSK (Pre-Shared Key), provide a simple way of

encrypting a wireless connection for high confidentiality. A Passphrase is used as a basis for encryption

methods (or cipher types) in a WLAN connection. The passphrases should be complex and as long as possible.

The number of ASCII characters of the Passphrase must be at least 8 and can go up to 63. For security reasons,

disclose this passphrase to the relevant users only and change it regularly.

Protected EAP

Before choosing the EAP protocol for your WPA/WPA2-Enterpise settings on the client end, please contact the

network administrator to make sure the system supports the protocol on the AP end. Detailed information on

these three popular EAP protocols is presented in the following sections:

EAP-TLS

TLS is the standards-based successor to the Secure Socket Layer (SSL). It can establish a trusted

communication channel over a distrusted network. TLS provides mutual authentication through certificate

exchange. EAP-TLS is also secure to use. You are required to submit a digital certificate to the authentication

server for validation, but the authentication server must also supply a certificate.

You can use WLAN 1/2  WLAN Certificate Settings to import your WLAN certificate and enable EAP-TLS

on the client end.

You can check the current certificate status in Current Status if it is available.

Certificate issued to: shows the certificate user.

Certificate issued by: shows the certificate issuer.

Certificate expiration date: indicates when the certificate becomes invalid.

EAP-TTLS

It is usually much easier to re-use existing authentication systems, such as a Windows domain or Active

Directory, LDAP directory, or Kerberos realm, rather than create a parallel authentication system. As a result,

TTLS (Tunneled TLS) and PEAP (Protected EAP) are used to support the use of so-called “legacy authentication

methods.”

TTLS and PEAP work in a similar way. First, they establish a TLS tunnel, like EAP-TLS, and validate whether the

network is trustworthy with digital certificates on the authentication server. This step is run to establish a

tunnel that protects the next step (or “inner” authentication) so it is sometimes referred to as the “outer”

authentication. Then the TLS tunnel is used to encrypt an older authentication protocol that authenticates the

user for the network.

AWK-6222 Web Console Configuration

3-19

As you can see, digital certificates are still needed for the outer authentication in a simplified form. Only a small

number of certificates are required, which can be generated by a small certificate authority. Certificate

reduction makes TTLS and PEAP much more popular than EAP-TLS.

The AWK-6222 provides some non-cryptographic EAP methods including PAP, CHAP, MS-CHAP, and

MS-CHAP-V2. These EAP methods are not recommended for direct use on wireless networks. However, they

may be useful as inner authentication methods with TTLS or PEAP.

Because the inner and outer authentications can use distinct user names in TTLS and PEAP, you can use an

anonymous user name for the outer authentication, while the true user name is shown only through the

encrypted channel. Remember, not all client software supports anonymous altercation. Confirm this with the

network administrator before you enable identity hiding in TTLS and PEAP.

authentication.

WLAN Certification Settings (for EAP-TLS in Redundant Client,

Client or Slave mode only)

When EAP-TLS is used, a WLAN Certificate will be required at the client end to support WPA/WPA2-Enterprise.

The AWK-6222 can support the PKCS #12, also known as Personal Information Exchange Syntax Standard,

certificate formats that define file formats commonly used to store private keys with accompanying public key

certificates, protected with a password-based symmetric key.

Current Status displays information for the current WLAN certificate imported into the AWK-6222. Nothing

will be displayed if no certificate is available.

Certificate issued to: shows the certificate user

Certificate issued by: shows the certificate issuer

Certificate expiration date: indicates when the certificate becomes invalid

You can import a new WLAN certificate in Import WLAN Certificate by following these steps:

1. Input the corresponding password (or key) in the Certificate private password field. Then click Submit

to set the password.

2. You can see the password displayed in the Certificate private password field. Then click on the Browse

button in Select certificate/key file and select the certificate file.

3. Click Upload Certificate File to import the certificate file. If it succeeds, you can see the information

uploaded in Current Certificate. If it fails, you may need to return to step 1 to set the password correctly

and then import the certificate file again.

Advanced Settings

Several advanced functions are available to increase the functionality of your AWK-6222 and wireless network

system. The DHCP server helps you deploy wireless clients efficiently. Packet filters provide security

mechanisms, such as firewalls, in different network layers. Moreover, the AWK-6222 can support the STP/RSTP

protocols to increase reliability across the entire network. In addition, SNMP support can ease the network

management via SNMP protocols.

DHCP Server (for AP-Client operation mode’s AP mode only)

DHCP (Dynamic Host Configuration Protocol) is a networking protocol that allows administrators to assign

temporary IP addresses to network computers by “leasing” an IP address to a user for a limited amount of time,

instead of assigning permanent IP addresses.

The AWK-6222 can act as a simplified DHCP server and easily assign IP addresses to your wireless clients by

responding to the DHCP requests from the client ends. The IP-related parameters you set on this page will also

be sent to the client.

You can also assign a static IP address to a specific client by entering its MAC address. The AWK-6222 provides

a Static DHCP mapping list with up to 16 entities. Remember to check the Active check box for each entity

to activate the setting.

You can check the IP assignment status under Status  DHCP Client List.

Packet Filters

The AWK-6222 includes various filters for IP-based packets going through LAN and WLAN interfaces. You can

set these filters as a firewall to help enhance network security.

MAC Filter

The AWK-6222’s MAC filter is a policy-based filter that can allow or filter out IP-based packets with specified

MAC addresses. The AWK-6222 provides eight fields for filtered MAC addresses. Remember to check the

Active check box for each entity to activate the setting.

IP Protocol Filter

The AWK-6222’s IP protocol filter is a policy-based filter that can allow or filter out IP-based packets with

specified IP protocol and source/destination IP addresses.

The AWK-6222 provides eight fields for setting IP protocol and source/destination IP addresses in your filtering

policy. Four IP protocols are available: All, ICMP, TCP, and UDP. You must specify either the Source IP or the

Destination IP. By combining IP addresses and netmasks, you can specify a single IP address or a range of IP

addresses to accept or drop. For example, “IP address 192.168.1.1 and netmask 255.255.255.255” refers to

the sole IP address 192.168.1.1. “IP address 192.168.1.1 and netmask 255.255.255.0” refers to the range of

IP addresses from 192.168.1.1 to 192.168.255. Remember to check the Active check box for each entity to

TCP/UDP Port Filter

The AWK-6222’s TCP/UDP port filter is a policy-based filter that can allow or filter out TCP/UDP-based packets

with a specified source or destination port.

The AWK-6222 provides eight fields for setting the range of source/destination ports of a specific protocol. In

addition to selecting TCP or UDP protocol, you can set either the source port, destination port, or both. The end

port can be left empty if only a single port is specified. Of course, the end port cannot be larger than the start

port.

The Application name is a text string that describes the corresponding entity with up to 31 characters.

RSTP Settings (for Master or Slave mode only)

The AWK-6222 supports IEEE802.1D Spanning Tree Protocol and IEEE802.1w Rapid STP standards. In addition

to eliminating unexpected path looping, STP/RSTP can provide a backup recovery path if a wired/ wireless path

fails accidentally. The reliability and availability of the network can increase because this fail-over function.

The AWK-6222’s STP/RSTP feature is disabled by default. To be completely effective, you must enable

RSTP/STP on every AWK-6222 connected to your network.

The following figures indicate which Spanning Tree Protocol parameters can be configured. A more detailed

explanation of each parameter is given below the figure.

The AWK-6222 supports SNMP V1/V2c/V3. SNMP V1 and SNMP V2c use a community string match for

authentication, which means that SNMP servers access all objects with read-only or read/write permissions

using the community string public/private (default value). SNMP V3, which requires you to select an

authentication level of MD5 or SHA, is the most secure protocol. You can also enable data encryption to

enhance data security.

Auto Warning Settings

Since industrial-grade devices are often located at the endpoints of a system, these devices will not always

know what is happening elsewhere on the network. This means that these devices, including wireless APs or

clients, must provide system maintainers with real-time alarm messages. This way even when system

administrators are out of the control room for an extended period, they can still be informed of the status of

devices almost instantaneously when exceptions occur.

In addition to logging these events, the AWK-6222 supports different approaches to warn engineers

automatically, such as SNMP trap, e-mail, and relay output. It also supports two digital inputs to integrate

sensors into your system to automate alarms by email and relay output.

The AWK-6222 has one relay output, which consists of two terminal block contacts on the AWK-6222’s top

panel. These relay contacts are used to indicate user-configured events and system failure.

The two wires attached to the relay contacts form an open circuit when a user-configured event is triggered. If

a user-configured event does not occur, the relay circuit will remain closed. For safety reasons, the relay circuit

is kept open when the AWK-6222 is not powered.

Trap

Traps can be used to signal abnormal conditions (notifications) to a management station. This trap-driven

notification can make your network more efficient.

Because a management station usually takes care of a large number of devices that have a large number of

objects, it will be overwhelming for the management station to poll or send requests to query every object on

every device. It would be more effective for the managed device agent to notify the management station when

necessary by sending a message known as a trap.

Configuring the Wireless Search Utility

The Broadcast Search function is used to locate all AWK-6222 APs that are connected to the same LAN as your

computer. After locating an AWK-6222, you will be able to change its IP address. Since the Broadcast Search

function searches by TCP packet and not IP address, it doesn’t matter if the AWK-6222 is configured as an AP

or Client. In either case, APs and Clients connected to the LAN will be located, regardless of whether or not they

are part of the same subnet as the host.

1. Start the Wireless Search Utility program.

5. Other Console Configurations

This chapter explains how to access the AWK-6222 for the first time. In addition to HTTP access, there are four

ways to access AWK-6222: serial console, Telnet console, SSH console, and HTTPS console. The serial console

connection method, which requires using a short serial cable to connect the AWK-6222 to a PC’s COM port, can

be used if you do not know the AWK-6222’s IP address. The other consoles can be used to access the

AWK-6222 over an Ethernet LAN, or over the Internet.

The following topics are covered in this chapter:

Configuration by Telnet and SSH Consoles

You may use a Telnet or SSH client to access the AWK-6222 and manage the console over a network. To access

the AWK-6222’s functions over the network from a PC host that is connected to the same LAN as the AWK-6222,

you need to make sure that the PC host and the AWK-6222 are on the same logical subnet. To do this, check

your PC host’s IP address and subnet mask.

AWK-6222’s default IP address is 192.168.127.253 and the default subnet mask is 255.255.255.0

nd then change the IP address to 192.168.127.xxx and subnet mask to 255.255.255.0.

Follow the steps below to access the console utility via Telnet or SSH client.

1. From Windows Desktop, run Start  Run, and then use Telnet to access the AWK-6222’s IP address from

This chapter provides more detailed information about wireless-related technologies. The information in this

chapter can help you administer your AWK-6222s and plan your industrial wireless network better.

The following topics are covered in this chapter:

Beacon

DTIM

Fragment

RTS Threshold

STP and RSTP

 The STP/RSTP Concept

 Differences between RSTP and STP

AWK-6222 References

6-2

Beacon

A beacon is a packet broadcast by the AP to keep the network synchronized. A beacon includes the wireless LAN

service area, the AP address, the Broadcast destination address, a time stamp, Delivery Traffic Indicator Maps

(DTIM), and the Traffic Indicator Message (TIM). Beacon Interval indicates the frequency interval of AP.

DTIM

Delivery Traffic Indication Map (DTIM) is contained in beacon frames. It indicates that broadcast and multicast

frames buffered by the AP will be delivered shortly. Lower settings result in more efficient networking, while

preventing your PC from dropping into power-saving sleep mode. Higher settings allow your PC to enter sleep

mode, thus saving power.

Fragment

A lower setting means smaller packets, which will create more packets for each transmission. If you have

decreased this value and experience high packet error rates, you can increase it again, but it will likely decrease

overall network performance. Only minor modifications of this value are recommended.

RTS Threshold

RTS Threshold (256-2346) – This setting determines how large a packet can be before the Access Point

coordinates transmission and reception to ensure efficient communication. This value should remain at its

default setting of 2,346. When you encounter inconsistent data flow, only minor modifications are

recommended.

STP and RSTP

The STP/RSTP Concept

Spanning Tree Protocol (STP) was designed to help reduce link failures in a network, and provide protection

from loops. Networks that have a complicated architecture are prone to broadcast storms caused by

unintended loops in the network. The STP protocol is part of the IEEE802.1D standard, 1998 Edition bridge

specification.

Rapid Spanning Tree Protocol (RSTP) implements the Spanning Tree Algorithm and Protocol defined by

IEEE802.1w-2001 standard. RSTP provides the following benefits:

• The topology of a bridged network will be determined much more quickly compared to STP.

• RSTP is backward compatible with STP, making it relatively easy to deploy. For example:

 Defaults to sending 802.1D-style BPDUs if packets with this format are received.

 STP (802.1D) and RSTP (802.1w) can operate on the LAN ports and WLAN ports (AP and WDS1-WDS8)

of the same AWK-6222.

This feature is particularly helpful when the AWK-6222 connects to older equipment, such as legacy switches.

AWK-6222 References

6-3

Differences between RSTP and STP

RSTP is similar to STP, but includes additional information in the BPDUs that allow each bridge to confirm that

it has taken action to prevent loops from forming when it decides to enable a link to a neighboring bridge.

Adjacent bridges connected via point-to-point links will be able to enable a link without waiting to ensure that

all other bridges in the network have had time to react to the change. The main benefit of RSTP is that the

configuration decision is made locally rather than network-wide, allowing RSTP to carry out automatic

configuration and restore a link faster than STP.
