TAP-6226 Getting Started

2-2

First-time Installation and Configuration

Before installing the TAP-6226, 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 TAP-6226 has a default

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

Step 1: Connect to a power source.

The TAP-6226 can be powered through the 110/220 VAC power input using an M23 power cable (must be

purchased separately).

Step 2: Connect the TAP-6226 to a notebook or PC.

Since the TAP-6226 supports MDI/MDI-X auto-sensing, you can use either a straight-through cable or

crossover cable to connect the TAP-6226 to a computer. If the LED indicator on TAP-6226’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 TAP-6226. Since the TAP-6226’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.

NOTE

After you select

Maintenance  Load Factory Default and click the Submit button, the TAP-6226 wil

l reset

to

factory default settings and the IP address will also reset to 192.168.127.253.

Step 4: Use the web-based manager to configure the TAP-6226

Open your computer’s web browser and type 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 user

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

and password and then click on the Login button:

NOTE

Default user name and password:

User Name: admin

Password: root

For security reasons, we strongly recommend changing the default password. To do so, select

Maintenance



Password

, and then follow the on-screen instructions.

Wireless Bridge

A bridge is a network component that connects two networks. The TAP-6226’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 TAP-6226’s dual RF bridge concept is different from using a single RF, because the TAP-6226 has dual RFs

that offer users a cascade link to bridge the two ends without narrowing down the throughput.

WLAN Security Settings

The TAP-6226 provides four standardized wireless security modes: Open, WEP (Wired Equivalent Privacy),

WPA (Wi-Fi Protected Access), and WPA2. The TAP-6226 supports several security modes with different

encryption types:

• 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 TAP-6226 can support three EAP methods: EAP-TLS, EAP-TTLS, and EAP-PEAP.

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

below:

Setting Description Factory Default

Open No authentication Open

WPA WPA is used

WPA2 Fully supports IEEE 802.11i with “TKIP/AES + 802.1X”

TAP-6226 Web Console Configuration

3-12

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 IEEE 802.11 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 TAP-6226 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 one of two Key types, HEX or 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 the 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 TAP-6226 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,

you should only disclose this passphrase to users who need to know it, and it should be changed regularly.

Generally speaking,

the security level will be higher if you set this value

to a smaller value, since the encryption keys will be change

more

frequently. The default value is 3600 seconds (60 minutes). You can consider using a l

onger time period

WPA/WPA2-Enterprise (for AP or Master Mode)

By selecting WPA type as Enterprise, you can use EAP (Extensible Authentication Protocol), a framework

authentication protocol used by 802.1X to provide network authentication. In these Enterprise-level security

modes, a back-end RADIUS (Remote Authentication Dial-In User Service) server is needed if IEEE 802.1X

functionality is enabled in WPA /WPA2. The IEEE 802.1X protocol also offers the possibility of carrying out

efficient connection authentication on a large-scale network. In this case, it is not necessary to exchange keys

or pass phrases.

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:

TAP-6226 Web Console Configuration

3-16

EAP-TLS

TLS is the standards-based successor to 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.

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 TAP-6226 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.

exchange inside of the tunnel. The TAP-6226 provides MS-CHAP-V2 merely as an EAP method for inner

authentication.

Several advanced functions are available to increase the functionality of your TAP-6226 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 TAP-6226 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.

Using Virtual LAN

Setting up Virtual LANs (VLANs) on your AWK series increases the efficiency of your network by dividing the

LAN into logical segments, as opposed to physical segments. In general, VLANs are easier to manage.

The Virtual LAN (VLAN) Concept

What is a VLAN?

A virtual LAN, or VLAN, is a collection of hosts with a common set of requirements. The hosts communicate as

if they were attached to the same broadcast domain, regardless of their physical location. A VLAN has the same

attributes as a physical LAN, but it allows you to group end stations together even if they are not connected to

the same network switch. Network reconfiguration can be done through software instead of physically

relocating devices.

VLANs can extend as far as the access point signal can reach. Clients can be segmented into wireless

sub-networks based on SSID and VLAN assignment. A Client can access the network by connecting to an AP

configured to support its assigned SSID/VLAN.

TAP-6226 Web Console Configuration

3-22

Benefits of VLANs

VLANs are used to conveniently, efficiently, and easily manage your network in the following ways:

• Manage adds, moves, and changes from a single point of contact

• Define and monitor groups

• Reduce broadcast and multicast traffic to unnecessary destinations

• Improve network performance and reduce latency

• Increase security

• Secure networks limit members to using resources on their own VLAN

• Clients can roam without compromising security

VLAN Workgroups and Traffic Management

The AP assigns clients to a VLAN based on a Network Name (SSID). The AP can support up to 9 SSIDs per radio

interface, with a unique VLAN configurable per SSID.

The AP matches packets transmitted or received to a network name with the associated VLAN. Traffic received

by a VLAN is only sent on the wireless interface associated with that same VLAN, eliminating unnecessary

traffic on the wireless LAN, conserving bandwidth, and maximizing throughput.

In addition to enhancing wireless traffic management, the VLAN-capable AP supports easy assignment of

wireless users to workgroups. In a typical scenario, each user VLAN represents a department workgroup; for

example, one VLAN could be used for a marketing department and the other for a human resources

department.

In this scenario, the AP would assign every packet it accepted to a VLAN. Each packet would then be identified

as marketing or human resources, depending on which wireless client received it. The AP would insert VLAN

headers or “tags” with identifiers into the packets transmitted on the wired backbone to a network switch.

Finally, the switch would be configured to route packets from the marketing department to the appropriate

corporate resources such as printers and servers. Packets from the human resources department could be

restricted to a gateway that allowed access to only the Internet. A member of the human resources department

NOTE

The VLAN feature can allow wireless clients to manage the AP. If the VLAN Management ID matches a VLAN ID,

then those wireless clients who are members of that VLAN will have AP management access.

CAUTION: Once a VLAN Management ID is configured and is equivalent to one of the VLAN IDs on the AP, all

members of that User VLAN will have management access to the AP. Be careful to restrict VLAN membership

to those with legitimate access to the AP.

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 TAP-6226 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 TAP-6226 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 TAP-6226 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 TAP-6226’s MAC filter is a policy-based filter that can allow or filter out IP-based packets with specified

MAC addresses. The TAP-6226 provides eight fields for filtered MAC addresses. Remember to check the Active

IP Protocol Filter

The TAP-6226’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 TAP-6226 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

activate the setting.

Accept

+ “no entity on list is activated” = all packets are denied (i.e., accept nothing)

TCP/UDP Port Filter

The TAP-6226’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 TAP-6226 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.

Remember to check the Active check box for each entity to activate the setting.

RSTP/Turbo Chain Settings (for Master or Slave mode only)

The TAP-6226 supports IEEE 802.1D Spanning Tree Protocol and IEEE 802.1w 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. This fail-over function can increase the reliability and availability of the network. The

TAP-6226 also supports Turbo Chain on its fiber interfaces.

The TAP-6226’s STP/RSTP feature is disabled by default. To be completely effective, you must enable

RSTP/STP on every TAP-6226 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.

TAP-6226 Web Console Configuration

3-28

Bridge priority

Setting Description Factory Default

User-selected

numerical value

You can increase the bridge priority by selecting a lower

number. Units with higher bridge priority are

more likely to be

chosen as the root of the Spanning Tree topology.

32768

Hello time

Setting Description Factory Default

User-selected

numerical value

(1 to 10 seconds)

The root of the Spanning Tree topology periodically sends out a

“hello” message to other devices on the network to check if the

topology is healthy. Hello time indicates how often the root

sends hello messages.

2 (seconds)

Forwarding delay

Setting Description Factory Default

User-selected

numerical value

(4 to 30 seconds)

The amount of time this device waits before

checking to see if it

should change to a different topology.

15 (seconds)

Max. age

Setting Description Factory Default

User-selected

numerical value

(6 to 40 seconds)

As a non-root role, if the device has not received a hello

message from the root longer than Max. age, it will

reconfigure itself as a root. Once two or more devices on the

network are recognized as a root, the devices will renegotiate

to set up a new Spanning Tree topology.

topology by inputting a lower number.

128

Port cost

Setting Description Factory Default

Enable/Disable Input a higher cost to indicate that this port is less suitable as a

node for the Spanning Tree topology

2000000

Edge port

Setting Description Factory Default

Checked/unchecked Sets a port, which no BPDU is expected to go through, as an

edge port

unchecked, except

WLAN1/2 ports

NOTE

We recommend

that you use the edge port setting for ports that are only connected to non-STP/RSTP

sub

-networks or end devices (PLCs, RTUs, etc.) as opposed to network equipment. This can prevent

unnecessary

waiting and negotiation for the

STP/RSTP protocol, and accelerate system initialization. When an

edge port

receives BPDUs, it can still function as an STP/RSTP port and start negotiation.

Setting an edge port

is different from disa

bling STP/RSTP on a port. If you disable STP/RSTP, a port will not deal with STP/RSTP

BPDUs at all.

TAP-6226 Web Console Configuration

Port Status

Port Status indicates the current Spanning Tree status of this port. Use Forwarding for normal transmission,

or Blocking to block transmission.

The Turbo Chain Concept

Moxa’s Turbo Chain is an advanced software-technology that gives network administrators the flexibility of

constructing any type of redundant network topology. When using the “chain” concept, you first connect the

APs in a chain and then simply link the two ends of the chain to an Ethernet network, as illustrated in the

following figure.

Turbo Chain can be used on industrial networks that have a complex topology. If the industrial network uses a

multi-ring architecture, Turbo Chain can be used to create flexible and scalable topologies with a fast

media-recovery time.

1. Select the Head AP, Tail AP, and Member AP.

2. Configure one port as the Head port and one port as the Member port in the Head AP, configure one port as

the Tail port and one port as the Member port in the Tail AP, and configure two ports as Member ports in

each of the Member switches.

3. Connect the Head AP, Tail AP, and Member APs as shown in the above diagram.

TAP-6226 Web Console Configuration

3-30

The path connecting to the Head port is the main path, and the path connecting to the Tail port is the backup

path of the Turbo Chain. Under normal conditions, packets are transmitted through the Head Port to the LAN

network. If any Turbo Chain path is disconnected, the Tail Port will be activated so that packet transmission can

continue.

Turbo Chain Status

Indicates whether Turbo Chain is enabled or disabled on the TAP-6226.

SNMP Agent

The TAP-6226 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.

The TAP-6226’s MIB can be found in the software CD and supports reading the attributes via SNMP. (Only get

method is supported.)

SNMP security modes and security levels supported by the TAP-6226 are shown in the following table. Select

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 TAP-6226 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.

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.

Save Configuration

The following figure shows how the TAP-6226 stores the setting changes into volatile and non-volatile memory.

Unless it is saved, all data stored in volatile memory will disappear when the TAP-6226 is shut down or rebooted.

Because the TAP-6226 starts up and initializes with the settings stored in flash memory, all new changes must

be saved to flash memory before restarting the TAP-6226.

This also means the new changes will not work unless you run either the Save Configuration function or the

Restart function.

After you click on Save Configuration in the left menu box, the following screen will appear. Click Save if you

wish to update the configuration settings in the flash memory at this time. Alternatively, you may choose to run

other functions and put off saving the configuration until later. However, the new setting changes will remain

in the non-volatile memory until you save the configurations.

Configuring AWK Search Utility

The Broadcast Search function is used to locate all TAP-6226 APs that are connected to the same LAN as your

computer. After locating a TAP-6226, 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 TAP-6226 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 AWK Search Utility. When the Login page appears, select the “Search AWK only” option to search

for AWKs and to view each AWK’s configuration. Select the “AWK management” option to assign IPs,

upgrade firmware, and locate devices.

5. Other Console Configurations

In this chapter, we explain how to access the TAP-6226 for the first time. In addition to HTTP access, there are

four ways to access the TAP-6226: serial console, Telnet console, SSH console, and HTTPS console. The serial

console connection method, which requires using a short serial cable to connect the TAP-6226 to a PC’s COM

port, can be used if you do not know the TAP-6226’s IP address. The other consoles can be used to access the

TAP-6226 over an Ethernet LAN, or over the Internet.

The following topics are covered in this chapter:

ATTENTION

1. You CANNOT connect to the TAP-6226 with two or more console configurations simultaneously.

2. You can connect to the TAP-6226 simultaneously by web browser and serial/Telnet/SSH console.

However, we strongly suggest that you do NOT

use more than one connection method at the same time.

Following this advice will allow you to maintain better control over the configuration of your TAP-6226.

RS-232 Console Configuration (115200, None, 8,
1, VT100)

The serial console connection method, which requires using a short serial cable to connect the TAP-6226 to a

PC’s COM port, can be used if you do not know the TAP-6226’s IP address. It is also convenient to use serial

console configurations when you cannot access the TAP-6226 over an Ethernet LAN, as would be the case if the

LAN cable gets disconnected or your network experiences a broadcast storm.

ATTENTION

Do not use the RS

-232 console manager when the TAP-6226 is powered in reverse voltage (e.g., -48 VDC),

ev

en though reverse voltage protection is supported. If you need to connect the RS-232 console using

reverse

voltage, M

oxa’s TCC-82 isolator is your best solution.

NOTE

We recommend using Moxa PComm

(Lite) Terminal Emulator, which can be downloaded free of charge from

Moxa’s website.

Before running PComm Terminal Emulator, use an RJ45 to DB9-F (or RJ45 to DB25-F) cable to connect the

TAP-6226’s RS-232 console port to your PC’s COM port (generally COM1 or COM2, depending on how your

system is set up). After installing PComm Terminal Emulator, take the following steps to access the RS-232

console utility.

1. From the Windows desktop, open the Start menu and select PComm Terminal Emulator from the PComm

(Lite) group.

2. Select Open under Port Manager to open a new connection.

3. The Communication Parameter page of the Property window opens. Select the appropriate COM port for

Console Connection, 115200 for Baud Rate, 8 for Data Bits, None for Parity, and 1 for Stop Bits.

4. Click on the Terminal tab, and select VT100 (or ANSI) for Terminal Type. Click on OK to continue.

5. The Console login screen will appear. Log in to the RS-232 console with the login name (default: admin)

and password (default: root, if no new password is set).

TAP-6226 Other Console Configurations

6. The TAP-6226’s device information and Main Menu will be displayed. Follow the onscreen instructions and

select the administration option you wish to perform.

NOTE

To modify the appearance of the PComm Terminal Emulator window, select

Edit  Font

and then choose the

desired formatting options.

ATTENTION

If you unplug the RS

-232 cable or trigger DTR, a disconnection event will be invoked to enforce logout for

network security.

You will need to log in again to resume operation.

Configuration by Telnet and SSH Consoles

You may use a Telnet or SSH client to access the TAP-6226 and manage the console over a network. To access

the TAP-6226’s functions over the network from a PC host that is connected to the same LAN as the TAP-6226,

you need to make sure that the PC host and the TAP-6226 are on the same logical subnet. To do this, check

your PC host’s IP address and subnet mask.

NOTE

The

TAP-6226’s default IP address is 192.168.127.253 and the default subnet mask is 255.255.255.0

(for

a Class C network). If you do not set these values properly, please check the network settings of your PC host

a

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, Start and then use Telnet to access the TAP-6226’s IP address from the Windows

Run window. (You may also issue the telnet command from an MS-DOS prompt.)

TAP-6226 Other Console Configurations

5-5

When using SSH client (e.g., PuTTY), run the client program (e.g., putty.exe) and then input the

TAP-6226’s IP address, specifying 22 for the SSH connection port.

2. The Console login screen will appear. Refer to the previous section, RS-232 Console Configuration, for

login and administration instructions.

Configuration by Web Browser with HTTPS/SSL

To secure your HTTP access, the TAP-6226 supports HTTPS/SSL encryption for all HTTP traffic. Perform the

following steps to access the TAP-6226’s web browser interface via HTTPS/SSL.

1. Open your web browser and type https://<TAP-6226’s IP address> in the address field. Press Enter to

establish the connection.

2. Warning messages will pop up to warn users that the security certificate was issued by a company they

have not yet chosen to trust.

3. Select Yes to accept the certificate issued by Moxa IW and then enter the TAP-6226’s web browser interface

secured via HTTPS/SSL. (The https protocol will be visible at the beginning of the url.) Use the menu tree

on the left side of the window to access the TAP-6226’s various functions.

Disabling Telnet and Browser Access

If you are connecting the TAP-6226 to a public network but do not intend to use its management functions over

the network, then we suggest disabling both Telnet Console and Web Configuration. To do this, access

Maintenance  Console Settings, as shown in the following figure.

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 the 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 IEEE 802.1D standard, 1998 Edition bridge

specification.

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

IEEE 802.1w-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 TAP-6226.

This feature is particularly helpful when the TAP-6226 connects to older equipment, such as legacy switches.

TAP-6226 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.
