First-Time Installation and Configuration
Before installing the AWK-3131A-M12-RCC, make sure that all items in the Package Checklist are in the box.
You will need access to a notebook computer or PC equipped with an Ethernet port. The AWK-3131A-M12-RCC
has a default IP address that must be used when connecting to the device for the first time.
• Step 1: Select the power source.
The AWK-3131A-M12-RCC can be powered by a DC power input or PoE (Power over Ethernet). The
AWK-3131A-M12-RCC will use whichever power source you choose.
• Step 2: Connect the AWK-3131A-M12-RCC to a notebook or PC.
Since the AWK-3131A-M12-RCC supports MDI/MDI-X auto-sensing, you can use either a straight-through
cable or crossover cable to connect the AWK-3131A-M12-RCC to a computer. The LED indicator on the
AWK-3131A-M12-RCC’s LAN port will light up when a connection is established.
• Step 3: Set up the computer’s IP address.
Choose an IP address on the same subnet as the AWK-3131A-M12-RCC. Since the AWK-3131A-M12-RCC’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
AWK-3131A-M12-RCC will be reset to factory default settings and the IP address will be reset to
192.168.127.253.
• Step 4: Use the web-based manager to configure the AWK-3131A-M12-RCC
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: moxa
For security reasons, we strongly recommend changing the default password. To do so, select Maintenance
Password, and then follow the on-screen instructions to change the password.

NOTE
After you click Submit to apply changes the web page will refresh (Updated) will appear on the page and a
blinking reminder will be shown on the upper-right corner of the web page:
To activate the changes click Restart and then Save and Restart after you change the settings. About 30
seconds are needed for the AWK-3131A-M12-RCC to complete the reboot procedure.
• Step 5: Select the AWK-3131A-M12-RCC operation mode.
By default, the AWK-3131A-M12-RCC’s operation mode is set to AP. You can change to Client mode in
Wireless Settings Operation Mode. Detailed information about configuring the
AWK-3131A-M12-RCC’s operation can be found in Chapter 3.
• Step 6: Test communications.
In the following sections we describe two test methods that can be used to ensure that a network
connection has been established.
Communication Testing
After installing the AWK-3131A-M12-RCC you can run a sample test to make sure the AWK-3131A-M12-RCC
and wireless connection are functioning normally. Two testing methods are described below. Use the first
method if you are using only one AWK-3131A-M12-RCC device, and use the second method if you are using two
or more AWK-3131A-M12-RCC units.
How to Test One AWK-3131A-M12-RCC
If you are only using one AWK-3131A-M12-RCC, you will need a second notebook computer equipped with a
WLAN card. Configure the WLAN card to connect to the AWK-3131A-M12-RCC (NOTE: the default SSID is
MOXA), and change the IP address of the second notebook (Notebook B) so that it is on the same subnet as
the first notebook (Notebook A), which is connected to the AWK-3131A-M12-RCC.
After configuring the WLAN card, establish a wireless connection with the AWK-3131A-M12-RCC and open the
Windows Command Prompt 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, recheck the
configuration to make sure the connections are correct.

How to Test Two or More AWK-3131A-M12-RCC Units
If you have two or more AWK-3131A-M12-RCC units, you will need a second notebook computer (Notebook B)
equipped with an Ethernet port. Use the default settings for the first AWK-3131A-M12-RCC connected to
notebook A and change the second or third AWK-3131A-M12-RCC connected to notebook B to Client mode, and
then configure the notebooks and AWK-3131A-M12-RCC units properly.
After setting up the testing environment, open the Windows Command Prompt 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.

WLAN Security Settings
The AWK-3131A-M12-RCC provides four standardized wireless security modes: Open, WEP (Wired Equivalent
Privacy), WPA (Wi-Fi Protected Access), and WPA2. Several security modes are available in the
AWK-3131A-M12-RCC by selecting Security mode and WPA type:
• Open: No authentication, no data encryption.
• WEP: Static WEP (Wired Equivalent Privacy) keys must be configured manually.
• WPA/WPA2-Personal: Also known as WPA/WPA2-PSK. You will 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-3131A-M12-RCC can support three EAP methods: EAP-TLS, EAP-TTLS, and EAP-PEAP.

For security reasons, you should NOT set security mode to Open System, since authentication and data
encryption are NOT performed in Open System mode.
WEP
According to the IEEE802.11 standard, WEP can be used for authentication and data encryption to maintain
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 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-3131A-M12-RCC
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 types, 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 represent significant improvements over the WEP encryption method.
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 is
regularly changed 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-3131A-M12-RCC 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 complicated and as long as
possible. There must be at least 8 ASCII characters in the Passphrase, and it could go up to 63. For security
reasons, this passphrase should only be disclosed to users who need it, and it should be changed regularly.

The key renewal value dictates how often the wireless AP encryption keys should be changed. The security
level is generally higher if you set the key renewal value to a shorter number, which forces the encryption keys
to be changed more frequently. The default value is 3600 seconds (6 minutes). Longer time periods can be
considered if the line is not very busy.
WPA/WPA2-Enterprise (for AP/Master mode)
By setting WPA type to 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 an
efficient connection authentication on a large-scale network. It is not necessary to exchange keys or
passphrases.

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 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 Basic Wireless Settings 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 has expired
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 creating 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 (EAP-TLS for example), and validate
whether the network is trustworthy with digital certificates on the authentication server. This step establishes
a tunnel that protects the next step (or “inner” authentication), and consequently is sometimes referred to as
“outer” authentication. The TLS tunnel is then used to encrypt an older authentication protocol that
authenticates the user for the network.
As you can see, digital certificates are still needed for 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.

AWK-3131A-M12-RCC
Web Console Configuration
The AWK-3131A-M12-RCC 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 and 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, with the true user name only shown through the encrypted
channel. Keep in mind that not all client software supports anonymous alteration. Confirm this with the network
administrator before you enable identity hiding in TTLS and PEAP.

NOTE
Most countries define a limit for the Equivalent Isotropically Radiated Power (EIRP) for an RF transmitting
system. The EIRP should not exceed the permitted limit for the country of operation. EIRP = transmission
power + antenna gain (dBi).
NOTE
Transmission power indicates the maximum value of transmission power which the user plans. However, the
real transmitted power depends on the radio module and some facts, such as country, regulatory limitations
and data rate. Please check the Transmission power in Status > Wireless Status for a real and updated value
of transmission power, which the AWK is currently using.

Several advanced functions are available to increase the functionality of your AWK-3131A-M12-RCC and
wireless network system. A VLAN is a collection of clients and hosts grouped together as if they were connected
to the broadcast domains in a layer 2 network. The DHCP server helps you deploy wireless clients efficiently.
Packet filters provide security mechanisms, such as firewalls, in different network layers. Moreover, the
AWK-3131A-M12-RCC can support STP/RSTP protocol to increase reliability across the entire network, and
SNMP support can make network management easier.

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, commonly known as a VLAN, is a group of hosts with a common set of requirements that
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 for end stations to be grouped together even if
they are not located on the same network switch. Network reconfiguration can be done through software
instead of physically relocating devices.
VLANs now extend as far as the reach of the access point signal. Clients can be segmented into wireless
sub-networks via SSID and VLAN assignment. A Client can access the network by connecting to an AP
configured to support its assigned SSID/VLAN.
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 network restricts members to resources on their own VLAN
• Clients 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. This eliminates 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 resource 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 resource, 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 resource
department could be restricted to a gateway that
allowed access to only the Internet. A member of
the human resource department could send and
receive e-mail and access the Internet, but would
be prevented from accessing servers or hosts on
the local corporate network.

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 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-3131A-M12-RCC can act as a simplified DHCP server and easily assign IP addresses to your DHCP
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-3131A-M12-RCC provides a Static DHCP mapping list with up to 16 entities. Be reminded 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.

RSTP Settings (for AP/Master/ACC mode only)
AWK-3131A-M12-RCC 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 path recovery if a wired/
wireless path fails accidentally. The reliability and availability can increase because this fail-over function.
AWK-3131A-M12-RCC’s STP/RSTP feature is disabled by default. To be completely effective, you must enable
RSTP/STP on every AWK-3131A-M12-RCC connected to your network. If AWK-3131A-M12-RCC plays a Client
role, which is connected to a device (PLC, RTU, etc.) as opposed to network switch equipment, it is not
necessary to enable STP/RSTP. The reason is that it will cause unnecessary negotiation.
AWK-3131A-M12-RCCs support STP/RSTP in AP mode only.
The following figures indicate which Spanning Tree Protocol parameters can be configured. A more detailed
explanation of each parameter is given below the figure.

Edge port
Setting
Description
Factory Default
Checked/ unchecked
Sets a port, which no BPDU expectedly goes through, as an
edge port
unchecked, except
AP port
NOTE
We recommend you set an edge port for the port, which is connected to a non-STP/RSTP sub-network or an
end device (PLC, RTU, etc.) as opposed to network equipment. This can prevent unnecessary waiting and
negotiation of 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 disabling STP/RSTP on a port. If you disable STP/RSTP, a port will not
deal with STP/RSTP BPDUs at all.
Port Status
Port Status indicates the current Spanning Tree status of this port. Use Forwarding for normal transmission,
or Blocking to block transmission.

SNMP Agent
The AWK-3131A-M12-RCC 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 AWK-3131A-M12-RCC’s MIB can be found in the software CD and supports reading the attributes via SNMP.
(Only get method is supported.)

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. 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-3131A-M12-RCC 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.

Relay
The AWK-3131A-M12-RCC has one relay output, which consists of 2 terminal block contacts on the
AWK-3131A-M12-RCC’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-3131A-M12-RCC is not powered.
Relay Event Types
You can check the box for Active to enable the event items. All default values are deactivated (unchecked).
Details for each event item can be found in the “System log Event Types” table on page 3-31.

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 overloading for the management station to poll or send requests to query every object on
every device. It would be better if the managed device agent could notify the management station by sending
a message known as a trap for the event.

SNMP Trap Receiver Settings
SNMP traps are defined in SMIv1 MIBs (SNMPv1) and SMIv2 MIBs (SNMPv2c). The two styles are basically
equivalent, and it is possible to convert between the two. You can set the parameters for SNMP trap receivers

LAN as your computer (host). After locating an AWK-3131A-M12-RCC, 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-3131A-M12-RCC 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.
First-time installation of the AWK Search Utility requires you to key in the management password. For security
reasons, be sure to have a system administrator install the AWK Search Utility on your computer.
The default management password for the AWK Search Utility is moxa.
1. Start the AWK Search Utility program. 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

Other Console Considerations
This chapter explains how to access the AWK-3131A-M12-RCC for the first time. In addition to HTTP access,
there are four ways to access AWK-3131A-M12-RCC: 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-3131A-M12-RCC to a PC’s COM port, can be used if you do not know the AWK-3131A-M12-RCC’s IP
address. The other consoles can be used to access the AWK-3131A-M12-RCC over an Ethernet LAN, or over the
Internet.
The following topics are covered in this chapter:

RS-232 Console Configuration (115200, None, 8,
1, VT100)
The serial console connection method, which requires using a short serial cable to connect the
AWK-3131A-M12-RCC to a PC’s COM port, can be used if you do not know the AWK-3131A-M12-RCC’s IP
address. It is also convenient to use serial console configurations when you cannot access the
AWK-3131A-M12-RCC over Ethernet LAN, such as in the case of LAN cable disconnections or broadcast
storming over the LAN.
NOTE
We recommend using Moxa PComm (Lite) Terminal Emulator, which can be downloaded free of charge
from Moxa’s website (www.moxa.com/support).
Before running the PComm Terminal Emulator program, use an RJ45 to DB9-F (or RJ45 to DB25-F) cable to
connect the AWK-3131A-M12-RCC’s RS-232 console port to your PC’s COM port (COM1 or COM2, depending on
how your system is set up). After installing the PComm Terminal Emulator, take the following steps to access
the RS-232 console utility.
1. From the Windows Start menu, select PComm (Lite) > PComm Terminal Emulator.
2. In the Port Manager menu of the emulator, click on Open.
The Property window opens up.
ATTENTION
Do not use the RS-232 console when the AWK-3131A-M12-RCC is powered by a reversed voltage.
(e.g., -48 VDC), even though reverse voltage protection is supported. If you need to connect the RS-232
console at a reverse voltage potential, ensure that the serial port on the PC/laptop is well protected before
attaching it to the AWK that is supplied by a -48 VDC system. An isolated USB-to-serial converter like Moxa
UPort 1250I is recommended to create a reliable connection with an AWK device. Alternatively, be sure to use
a serial isolator, such as Moxa TCC-82, to protect both the AWK's serial console and your serial port.

5. Key in the number corresponding to the menu option that you would like to select.
NOTE
To modify the appearance of the PComm Terminal Emulator window, select Edit Font and then choose the
desired formatting options.
NOTE
The AWK's serial console needs to detect a DSR signal to activate the console output. Be sure to use a full
8-wire serial cable instead of a 3-wire (Tx/Rx/GND only). For a good connection to the AWK device we
recommend using Moxa serial console cable - CBL-RJ45F9-150.
Configuring Through Telnet and SSH Consoles
You may use Telnet or SSH client to access the AWK-3131A-M12-RCC and manage the console over a network.
To access the AWK-3131A-M12-RCC’s functions over the network from a PC host that is connected to the same
LAN as the AWK-3131A-M12-RCC, you need to make sure that the PC host and the AWK-3131A-M12-RCC are
on the same logical subnet. To do this, check your PC host’s IP address and subnet mask.
ATTENTION
If you unplug the RS-232 cable or disable the DTR signal, a disconnection event will be evoked to enforce
logout for network security. You will need to log in again to resume operation.

settings of your PC host and 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-3131A-M12-RCC’s IP
address from the Windows Run window (you may also issue the telnet command from the MS-DOS
prompt).
NOTE
Telnet is not a default service in Windows 7 and later versions for a PC/laptop. In order to use the telnet service,
you will need to activate it from Control Panel Programs Turn Windows features on or off. Select
Telnet Client and press OK.
2. When using the SSH client (e.g., PuTTY), run the client program and then input the AWK-3131A-M12-RCC’s
IP address, specifying 22 for the SSH connection port.
3. The Console login screen will appear. Please refer to the previous paragraph “RS-232 Console Configuration”
and for login and administration.
Configuring HTTPS/SSL Secure Access Through
a Web Browser

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 is used to indicate 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, Master, Slave, and
ACC modes) of the same AWK-3131A-M12-RCC.
This feature is particularly helpful when the AWK-3131A-M12-RCC connects to older equipment, such as legacy
switches.
AWK-3131A-M12-RCC
References
A-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.
