CHAPTER 21
Log
21.1 Overview
The web configurator allows you to choose which categories of events and/or alerts to have the XMG
log and then display the logs or have the XMG send them to an administrator (as e-mail) or to a syslog
server.
21.1.1 What You Can Do in this Chapter
• Use the System Log screen to see the system logs (Section 21.2 on page 204).
• Use the Security Log screen to see the security-related logs for the categories that you select (Section
21.3 on page 204).
21.1.2 What You Need To Know
The following terms and concepts may help as you read this chapter.
Alerts and Logs
An alert is a type of log that warrants more serious attention. They include system errors, attacks (access
control) and attempted access to blocked web sites. Some categories such as System Errors consist of
both logs and alerts. You may differentiate them by their color in the View Log screen. Alerts display in
red and logs display in black.
Syslog Overview
The syslog protocol allows devices to send event notification messages across an IP network to syslog
servers that collect the event messages. A syslog-enabled device can generate a syslog message and
send it to a syslog server.
Syslog is defined in RFC 3164. The RFC defines the packet format, content and system log related
information of syslog messages. Each syslog message has a facility and severity level. The syslog facility
identifies a file in the syslog server. Refer to the documentation of your syslog program for details. The
following table describes the syslog severity levels.
Table 98 Syslog Severity Levels
CODE SEVERITY
0 Emergency: The system is unusable.
1 Alert: Action must be taken immediately.
2 Critical: The system condition is critical.
3 Error: There is an error condition on the system.
4 Warning: There is a warning condition on the system.

CHAPTER 23
ARP Table
23.1 Overview
Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP address) to
a physical machine address, also known as a Media Access Control or MAC address, on the local area
network.
An IP (version 4) address is 32 bits long. In an Ethernet LAN, MAC addresses are 48 bits long. The ARP
Table maintains an association between each MAC address and its corresponding IP address.
23.1.1 How ARP Works
When an incoming packet destined for a host device on a local area network arrives at the device, the
device's ARP program looks in the ARP Table and, if it finds the address, sends it to the device.
If no entry is found for the IP address, ARP broadcasts the request to all the devices on the LAN. The
device fills in its own MAC and IP address in the sender address fields, and puts the known IP address of
the target in the target IP address field. In addition, the device puts all ones in the target MAC field
(FF.FF.FF.FF.FF.FF is the Ethernet broadcast address). The replying device (which is either the IP address of
the device being sought or the router that knows the way) replaces the broadcast address with the
target's MAC address, swaps the sender and target pairs, and unicasts the answer directly back to the
requesting machine. ARP updates the ARP Table for future reference and then sends the packet to the
MAC address that replied.

xDSL Port Details
Upstream These are the statistics for the traffic direction going out from the port to the service provider.
Downstream These are the statistics for the traffic direction coming into the port from the service provider.
Line Rate These are the data transfer rates at which the port is sending and receiving data.
Actual Net Data
Rate
These are the rates at which the port is sending and receiving the payload data without
transport layer protocol headers and traffic.
Trellis Coding This displays whether or not the port is using Trellis coding for traffic it is sending and receiving.
Trellis coding helps to reduce the noise in ADSL transmissions. Trellis may reduce throughput but
it makes the connection more stable.
SNR Margin This is the upstream and downstream Signal-to-Noise Ratio margin (in dB). A DMT sub-carrier’s
SNR is the ratio between the received signal power and the received noise power. The signal-
to-noise ratio margin is the maximum that the received noise power could increase with the
system still being able to meet its transmission targets.
Actual Delay This is the upstream and downstream interleave delay. It is the wait (in milliseconds) that
determines the size of a single block of data to be interleaved (assembled) and then
transmitted. Interleave delay is used when transmission error correction (Reed- Solomon) is
necessary due to a less than ideal telephone line. The bigger the delay, the bigger the data
block size, allowing better error correction to be performed.
Transmit Power This is the upstream and downstream far end actual aggregate transmit power (in dBm).
Upstream is how much power the port is using to transmit to the service provider. Downstream is
how much port the service provider is using to transmit to the port.
Receive Power Upstream is how much power the service provider is receiving from the port. Downstream is
how much power the port is receiving from the service provider.
Actual INP Sudden spikes in the line’s level of external noise (impulse noise) can cause errors and result in
lost packets. This could especially impact the quality of multimedia traffic such as voice or
video. Impulse noise protection (INP) provides a buffer to allow for correction of errors caused
by error correction to deal with this. The number of DMT (Discrete Multi-Tone) symbols shows the
level of impulse noise protection for the upstream and downstream traffic. A higher symbol
value provides higher error correction capability, but it causes overhead and higher delay
which may increase error rates in received multimedia data.
Total Attenuation This is the upstream and downstream line attenuation, measured in decibels (dB). This
attenuation is the difference between the power transmitted at the near-end and the power
received at the far-end. Attenuation is affected by the channel characteristics (wire gauge,
quality, condition and length of the physical line).
Attainable Net
Data Rate
These are the highest theoretically possible transfer rates at which the port could send and
receive payload data without transport layer protocol headers and traffic.
xDSL Counters
Downstream These are the statistics for the traffic direction coming into the port from the service provider.
Upstream These are the statistics for the traffic direction going out from the port to the service provider.
FEC This is the number of Far End Corrected blocks.
CRC This is the number of Cyclic Redundancy Checks.
ES This is the number of Errored Seconds meaning the number of seconds containing at least one
errored block or at least one defect.
SES This is the number of Severely Errored Seconds meaning the number of seconds containing 30%
or more errored blocks or at least one defect. This is a subset of ES.
UAS This is the number of UnAvailable Seconds.
LOS This is the number of Loss Of Signal seconds.
LOF This is the number of Loss Of Frame seconds.
LOM This is the number of Loss of Margin seconds.

CHAPTER 30
SNMP
30.1 Overview
This chapter explains how to configure the SNMP settings on the XMG.
30.2 The SNMP Screen
Simple Network Management Protocol is a protocol used for exchanging management information
between network devices. Your XMG supports SNMP agent functionality, which allows a manager
station to manage and monitor the XMG through the network. The XMG supports SNMP version one
(SNMPv1) and version two (SNMPv2c). The next figure illustrates an SNMP management operation.
Figure 144 SNMP Management Model
An SNMP managed network consists of two main types of component: agents and a manager.
An agent is a management software module that resides in a managed device (the XMG). An agent
translates the local management information from the managed device into a form compatible with
SNMP. The manager is the console through which network administrators perform network management
functions. It executes applications that control and monitor managed devices.
The managed devices contain object variables/managed objects that define each piece of
information to be collected about a device. Examples of variables include such as number of packets
received, node port status etc. A Management Information Base (MIB) is a collection of managed
objects. SNMP allows a manager and agents to communicate for the purpose of accessing these
objects.
Chapter 30 SNMP
XMG3512-B10A User’s Guide

SNMP itself is a simple request/response protocol based on the manager/agent model. The manager
issues a request and the agent returns responses using the following protocol operations:
• Get - Allows the manager to retrieve an object variable from the agent.
• GetNext - Allows the manager to retrieve the next object variable from a table or list within an agent.
In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it initiates a Get
operation, followed by a series of GetNext operations.
• Set - Allows the manager to set values for object variables within an agent.
• Trap - Used by the agent to inform the manager of some events.

Daylight Saving Time starts in most parts of the United States on the second Sunday of March.
Each time zone in the United States starts using Daylight Saving Time at 2 A.M. local time. So in
the United States, set the day to Second, Sunday, the month to March and the time to 2 in the
Hour field.
Daylight Saving Time starts in the European Union on the last Sunday of March. All of the time
zones in the European Union start using Daylight Saving Time at the same moment (1 A.M.
GMT or UTC). So in the European Union you would set the day to Last, Sunday and the month
to March. The time you select depends on your time zone. In Germany for instance, you
would select 2 in the Hour field because Germany's time zone is one hour ahead of GMT or
UTC (GMT+1).
End Rule Configure the day and time when Daylight Saving Time ends if you enabled Daylight Saving.
You can select a specific date in a particular month or a specific day of a specific week in a

CHAPTER 36
Diagnostic
36.1 Overview
The Diagnostic screens display information to help you identify problems with the XMG.
The route between a CO VDSL switch and one of its CPE may go through switches owned by
independent organizations. A connectivity fault point generally takes time to discover and impacts
subscriber’s network access. In order to eliminate the management and maintenance efforts, IEEE
802.1ag is a Connectivity Fault Management (CFM) specification which allows network administrators to
identify and manage connection faults. Through discovery and verification of the path, CFM can
detect, analyze and isolate connectivity faults in bridged LANs.
36.1.1 What You Can Do in this Chapter
• The Ping & TraceRoute & NsLookup screen lets you ping an IP address or trace the route packets take
to a host (Section 36.3 on page 238).
• The 802.1ag screen lets you perform CFM actions (Section 36.4 on page 238).
• The OAM Ping screen lets you send an ATM OAM (Operation, Administration and Maintenance)
packet to verify the connectivity of a specific PVC. (Section 36.5 on page 239).
36.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
How CFM Works
A Maintenance Association (MA) defines a VLAN and associated Maintenance End Point (MEP) ports
on the device under a Maintenance Domain (MD) level. An MEP port has the ability to send
Connectivity Check Messages (CCMs) and get other MEP ports information from neighbor devices’
CCMs within an MA.
CFM provides two tests to discover connectivity faults.
• Loopback test - checks if the MEP port receives its Loop Back Response (LBR) from its target after it
sends the Loop Back Message (LBM). If no response is received, there might be a connectivity fault
between them.
• Link trace test - provides additional connectivity fault analysis to get more information on where the
fault is. If an MEP port does not respond to the source MEP, this may indicate a fault. Administrators
can take further action to check and resume services from the fault according to the line
connectivity status report.

ATM sets up virtual circuits over which end systems communicate. The terminology for virtual circuits is as
follows:
Figure 162 Virtual Circuit Topology
Think of a virtual path as a cable that contains a bundle of wires. The cable connects two points and
wires within the cable provide individual circuits between the two points. In an ATM cell header, a VPI
(Virtual Path Identifier) identifies a link formed by a virtual path; a VCI (Virtual Channel Identifier)
identifies a channel within a virtual path. A series of virtual paths make up a virtual circuit.
F4 cells operate at the virtual path (VP) level, while F5 cells operate at the virtual channel (VC) level. F4
cells use the same VPI as the user data cells on VP connections, but use different predefined VCI values.
F5 cells use the same VPI and VCI as the user data cells on the VC connections, and are distinguished
from data cells by a predefinded Payload Type Identifier (PTI) in the cell header. Both F4 flows and F5
flows are bidirectional and have two types.
• segment F4 flows (VCI=3)
• end-to-end F4 flows (VCI=4)
• segment F5 flows (PTI=100)
• end-to-end F5 flows (PTI=101)
OAM F4 or F5 tests are used to check virtual path or virtual channel availability between two DSL
devices. Segment flows are terminated at the connecting point which terminates a VP or VC segment.
End-to-end flows are terminated at the end point of a VP or VC connection, where an ATM link is
terminated. Segment loopback tests allow you to verify integrity of a PVC to the nearest neighboring
ATM device. End-to-end loopback tests allow you to verify integrity of an end-to-end PVC.
Note: The DSLAM to which the XMG is connected must also support ATM F4 and/or F5 to use
this test.
Note: This screen is available only when you configure an ATM layer-2 interface.

37.4 Wireless Internet Access
What factors may cause intermittent or unstabled wireless connection? How can I solve this
problem?
The following factors may cause interference:
• Obstacles: walls, ceilings, furniture, and so on.
• Building Materials: metal doors, aluminum studs.
• Electrical devices: microwaves, monitors, electric motors, cordless phones, and other wireless devices.
To optimize the speed and quality of your wireless connection, you can:
• Move your wireless device closer to the AP if the signal strength is low.
• Reduce wireless interference that may be caused by other wireless networks or surrounding wireless
electronics such as cordless phones.
• Place the AP where there are minimum obstacles (such as walls and ceilings) between the AP and
the wireless client.
• Reduce the number of wireless clients connecting to the same AP simultaneously, or add additional
APs if necessary.
• Try closing some programs that use the Internet, especially peer-to-peer applications. If the wireless
client is sending or receiving a lot of information, it may have too many programs open that use the
Internet.
What is a Server Set ID (SSID)?
An SSID is a name that uniquely identifies a wireless network. The AP and all the clients within a wireless
network must use the same SSID.

Wireless LAN Topologies
This section discusses ad-hoc and infrastructure wireless LAN topologies.
Ad-hoc Wireless LAN Configuration
The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers
with wireless adapters (A, B, C). Any time two or more wireless adapters are within range of each other,
they can set up an independent network, which is commonly referred to as an ad-hoc network or
Independent Basic Service Set (IBSS). The following diagram shows an example of notebook computers
using wireless adapters to form an ad-hoc wireless LAN.
Figure 164 Peer-to-Peer Communication in an Ad-hoc Network
BSS
A Basic Service Set (BSS) exists when all communications between wireless clients or between a wireless
client and a wired network client go through one access point (AP).
Intra-BSS traffic is traffic between wireless clients in the BSS. When Intra-BSS is enabled, wireless client A
and B can access the wired network and communicate with each other. When Intra-BSS is disabled,
wireless client A and B can still access the wired network but cannot communicate with each other.
Appendix B Wireless LANs
XMG3512-B10A User’s Guide
256
Figure 165 Basic Service Set
ESS
An Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an access point,
with each access point connected together by a wired network. This wired connection between APs is
called a Distribution System (DS).
This type of wireless LAN topology is called an Infrastructure WLAN. The Access Points not only provide
communication with the wired network but also mediate wireless network traffic in the immediate
neighborhood.
An ESSID (ESS IDentification) uniquely identifies each ESS. All access points and their associated wireless
clients within the same ESS must have the same ESSID in order to communicate.
Appendix B Wireless LANs
XMG3512-B10A User’s Guide
257
Figure 166 Infrastructure WLAN
Channel
A channel is the radio frequency(ies) used by wireless devices to transmit and receive data. Channels
available depend on your geographical area. You may have a choice of channels (for your region) so
you should use a channel different from an adjacent AP (access point) to reduce interference.
Interference occurs when radio signals from different access points overlap causing interference and
degrading performance.
Adjacent channels partially overlap however. To avoid interference due to overlap, your AP should be
on a channel at least five channels away from a channel that an adjacent AP is using. For example, if
your region has 11 channels and an adjacent AP is using channel 1, then you need to select a channel
between 6 or 11.
RTS/CTS
A hidden node occurs when two stations are within range of the same access point, but are not within
range of each other. The following figure illustrates a hidden node. Both stations (STA) are within range
of the access point (AP) or wireless gateway, but out-of-range of each other, so they cannot "hear"
each other, that is they do not know if the channel is currently being used. Therefore, they are
considered hidden from each other.
Appendix B Wireless LANs
XMG3512-B10A User’s Guide
258
Figure 167 RTS/CTS
When station A sends data to the AP, it might not know that the station B is already using the channel. If
these two stations send data at the same time, collisions may occur when both sets of data arrive at the
AP at the same time, resulting in a loss of messages for both stations.
RTS/CTS is designed to prevent collisions due to hidden nodes. An RTS/CTS defines the biggest size data
frame you can send before an RTS (Request To Send)/CTS (Clear to Send) handshake is invoked.
When a data frame exceeds the RTS/CTS value you set (between 0 to 2432 bytes), the station that wants
to transmit this frame must first send an RTS (Request To Send) message to the AP for permission to send
it. The AP then responds with a CTS (Clear to Send) message to all other stations within its range to notify
them to defer their transmission. It also reserves and confirms with the requesting station the time frame
for the requested transmission.
Stations can send frames smaller than the specified RTS/CTS directly to the AP without the RTS (Request
To Send)/CTS (Clear to Send) handshake.
You should only configure RTS/CTS if the possibility of hidden nodes exists on your network and the "cost"
of resending large frames is more than the extra network overhead involved in the RTS (Request To
Send)/CTS (Clear to Send) handshake.
If the RTS/CTS value is greater than the Fragmentation Threshold value (see next), then the RTS (Request
To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before
they reach RTS/CTS size.
Note: Enabling the RTS Threshold causes redundant network overhead that could negatively
affect the throughput performance instead of providing a remedy.
Fragmentation Threshold
A Fragmentation Threshold is the maximum data fragment size (between 256 and 2432 bytes) that can
be sent in the wireless network before the AP will fragment the packet into smaller data frames.
A large Fragmentation Threshold is recommended for networks not prone to interference while you
should set a smaller threshold for busy networks or networks that are prone to interference.
If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) you set then the
RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be
fragmented before they reach RTS/CTS size.

IEEE 802.11g Wireless LAN
IEEE 802.11g is fully compatible with the IEEE 802.11b standard. This means an IEEE 802.11b adapter can
interface directly with an IEEE 802.11g access point (and vice versa) at 11 Mbps or lower depending on
range. IEEE 802.11g has several intermediate rate steps between the maximum and minimum data
rates. The IEEE 802.11g data rate and modulation are as follows:
Wireless Security Overview
Wireless security is vital to your network to protect wireless communication between wireless clients,
access points and the wired network.
Wireless security methods available on the XMG are data encryption, wireless client authentication,
restricting access by device MAC address and hiding the XMG identity.
The following figure shows the relative effectiveness of these wireless security methods available on your
XMG.
Note: You must enable the same wireless security settings on the XMG and on all wireless
clients that you want to associate with it.
IEEE 802.1x
In June 2001, the IEEE 802.1x standard was designed to extend the features of IEEE 802.11 to support
extended authentication as well as providing additional accounting and control features. It is
supported by Windows XP and a number of network devices. Some advantages of IEEE 802.1x are:
• User based identification that allows for roaming.
• Support for RADIUS (Remote Authentication Dial In User Service, RFC 2138, 2139) for centralized user
profile and accounting management on a network RADIUS server.

• Support for EAP (Extensible Authentication Protocol, RFC 2486) that allows additional authentication
methods to be deployed with no changes to the access point or the wireless clients.
RADIUS
RADIUS is based on a client-server model that supports authentication, authorization and accounting.
The access point is the client and the server is the RADIUS server. The RADIUS server handles the following
tasks:
• Authentication
Determines the identity of the users.
•Authorization
Determines the network services available to authenticated users once they are connected to the
network.
• Accounting
Keeps track of the client’s network activity.
RADIUS is a simple package exchange in which your AP acts as a message relay between the wireless
client and the network RADIUS server.
Types of RADIUS Messages
The following types of RADIUS messages are exchanged between the access point and the RADIUS
server for user authentication:
• Access-Request
Sent by an access point requesting authentication.
• Access-Reject
Sent by a RADIUS server rejecting access.
• Access-Accept
Sent by a RADIUS server allowing access.
• Access-Challenge
Sent by a RADIUS server requesting more information in order to allow access. The access point sends
a proper response from the user and then sends another Access-Request message.
The following types of RADIUS messages are exchanged between the access point and the RADIUS
server for user accounting:
• Accounting-Request
Sent by the access point requesting accounting.
• Accounting-Response
Sent by the RADIUS server to indicate that it has started or stopped accounting.
In order to ensure network security, the access point and the RADIUS server use a shared secret key,
which is a password, they both know. The key is not sent over the network. In addition to the shared key,
password information exchanged is also encrypted to protect the network from unauthorized access.
Appendix B Wireless LANs
XMG3512-B10A User’s Guide
261
Types of EAP Authentication
This section discusses some popular authentication types: EAP-MD5, EAP-TLS, EAP-TTLS, PEAP and LEAP.
Your wireless LAN device may not support all authentication types.
EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the IEEE 802.1x
transport mechanism in order to support multiple types of user authentication. By using EAP to interact
with an EAP-compatible RADIUS server, an access point helps a wireless station and a RADIUS server
perform authentication.
The type of authentication you use depends on the RADIUS server and an intermediary AP(s) that
supports IEEE 802.1x.
For EAP-TLS authentication type, you must first have a wired connection to the network and obtain the
certificate(s) from a certificate authority (CA). A certificate (also called digital IDs) can be used to
authenticate users and a CA issues certificates and guarantees the identity of each certificate owner.
EAP-MD5 (Message-Digest Algorithm 5)
MD5 authentication is the simplest one-way authentication method. The authentication server sends a
challenge to the wireless client. The wireless client ‘proves’ that it knows the password by encrypting the
password with the challenge and sends back the information. Password is not sent in plain text.
However, MD5 authentication has some weaknesses. Since the authentication server needs to get the
plaintext passwords, the passwords must be stored. Thus someone other than the authentication server
may access the password file. In addition, it is possible to impersonate an authentication server as MD5
authentication method does not perform mutual authentication. Finally, MD5 authentication method
does not support data encryption with dynamic session key. You must configure WEP encryption keys for
data encryption.
EAP-TLS (Transport Layer Security)
With EAP-TLS, digital certifications are needed by both the server and the wireless clients for mutual
authentication. The server presents a certificate to the client. After validating the identity of the server,
the client sends a different certificate to the server. The exchange of certificates is done in the open
before a secured tunnel is created. This makes user identity vulnerable to passive attacks. A digital
certificate is an electronic ID card that authenticates the sender’s identity. However, to implement EAP-
TLS, you need a Certificate Authority (CA) to handle certificates, which imposes a management
overhead.
EAP-TTLS (Tunneled Transport Layer Service)
EAP-TTLS is an extension of the EAP-TLS authentication that uses certificates for only the server-side
authentications to establish a secure connection. Client authentication is then done by sending
username and password through the secure connection, thus client identity is protected. For client
authentication, EAP-TTLS supports EAP methods and legacy authentication methods such as PAP, CHAP,
MS-CHAP and MS-CHAP v2.
PEAP (Protected EAP)
Like EAP-TTLS, server-side certificate authentication is used to establish a secure connection, then use
simple username and password methods through the secured connection to authenticate the clients,
thus hiding client identity. However, PEAP only supports EAP methods, such as EAP-MD5, EAP-MSCHAPv2
Appendix B Wireless LANs
XMG3512-B10A User’s Guide
262
and EAP-GTC (EAP-Generic Token Card), for client authentication. EAP-GTC is implemented only by
Cisco.
LEAP
LEAP (Lightweight Extensible Authentication Protocol) is a Cisco implementation of IEEE 802.1x.
Dynamic WEP Key Exchange
The AP maps a unique key that is generated with the RADIUS server. This key expires when the wireless
connection times out, disconnects or reauthentication times out. A new WEP key is generated each
time reauthentication is performed.
If this feature is enabled, it is not necessary to configure a default encryption key in the wireless security
configuration screen. You may still configure and store keys, but they will not be used while dynamic
WEP is enabled.
Note: EAP-MD5 cannot be used with Dynamic WEP Key Exchange
For added security, certificate-based authentications (EAP-TLS, EAP-TTLS and PEAP) use dynamic keys for
data encryption. They are often deployed in corporate environments, but for public deployment, a
simple user name and password pair is more practical. The following table is a comparison of the
features of authentication types.
WPA and WPA2
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.11i) is a wireless
security standard that defines stronger encryption, authentication and key management than WPA.
Key differences between WPA or WPA2 and WEP are improved data encryption and user
authentication.
If both an AP and the wireless clients support WPA2 and you have an external RADIUS server, use WPA2
for stronger data encryption. If you don't have an external RADIUS server, you should use WPA2-PSK
(WPA2-Pre-Shared Key) that only requires a single (identical) password entered into each access point,
wireless gateway and wireless client. As long as the passwords match, a wireless client will be granted
access to a WLAN.
If the AP or the wireless clients do not support WPA2, just use WPA or WPA-PSK depending on whether
you have an external RADIUS server or not.

XMG3512-B10A User’s Guide
263
Select WEP only when the AP and/or wireless clients do not support WPA or WPA2. WEP is less secure
than WPA or WPA2.
Encryption
WPA improves data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check
(MIC) and IEEE 802.1x. WPA2 also uses TKIP when required for compatibility reasons, but offers stronger
encryption than TKIP with Advanced Encryption Standard (AES) in the Counter mode with Cipher block
chaining Message authentication code Protocol (CCMP).
TKIP uses 128-bit keys that are dynamically generated and distributed by the authentication server. AES
(Advanced Encryption Standard) is a block cipher that uses a 256-bit mathematical algorithm called
Rijndael. They both include a per-packet key mixing function, a Message Integrity Check (MIC) named
Michael, an extended initialization vector (IV) with sequencing rules, and a re-keying mechanism.
WPA and WPA2 regularly change and rotate the encryption keys so that the same encryption key is
never used twice.
The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then sets up a key hierarchy
and management system, using the PMK to dynamically generate unique data encryption keys to
encrypt every data packet that is wirelessly communicated between the AP and the wireless clients. This
all happens in the background automatically.
The Message Integrity Check (MIC) is designed to prevent an attacker from capturing data packets,
altering them and resending them. The MIC provides a strong mathematical function in which the
receiver and the transmitter each compute and then compare the MIC. If they do not match, it is
assumed that the data has been tampered with and the packet is dropped.
By generating unique data encryption keys for every data packet and by creating an integrity
checking mechanism (MIC), with TKIP and AES it is more difficult to decrypt data on a Wi-Fi network than
WEP and difficult for an intruder to break into the network.
The encryption mechanisms used for WPA(2) and WPA(2)-PSK are the same. The only difference
between the two is that WPA(2)-PSK uses a simple common password, instead of user-specific
credentials. The common-password approach makes WPA(2)-PSK susceptible to brute-force password-
guessing attacks but it’s still an improvement over WEP as it employs a consistent, single, alphanumeric
password to derive a PMK which is used to generate unique temporal encryption keys. This prevent all
wireless devices sharing the same encryption keys. (a weakness of WEP)
User Authentication
WPA and WPA2 apply IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate wireless
clients using an external RADIUS database. WPA2 reduces the number of key exchange messages from
six to four (CCMP 4-way handshake) and shortens the time required to connect to a network. Other
WPA2 authentication features that are different from WPA include key caching and pre-authentication.
These two features are optional and may not be supported in all wireless devices.
Key caching allows a wireless client to store the PMK it derived through a successful authentication with
an AP. The wireless client uses the PMK when it tries to connect to the same AP and does not need to go
with the authentication process again.
Pre-authentication enables fast roaming by allowing the wireless client (already connecting to an AP) to
perform IEEE 802.1x authentication with another AP before connecting to it.

Wireless Client WPA Supplicants
A wireless client supplicant is the software that runs on an operating system instructing the wireless client
how to use WPA. At the time of writing, the most widely available supplicant is the WPA patch for
Windows XP, Funk Software's Odyssey client.
The Windows XP patch is a free download that adds WPA capability to Windows XP's built-in "Zero
Configuration" wireless client. However, you must run Windows XP to use it.
WPA(2) with RADIUS Application Example
To set up WPA(2), you need the IP address of the RADIUS server, its port number (default is 1812), and the
RADIUS shared secret. A WPA(2) application example with an external RADIUS server looks as follows. "A"
is the RADIUS server. "DS" is the distribution system.
1The AP passes the wireless client's authentication request to the RADIUS server.
2The RADIUS server then checks the user's identification against its database and grants or denies
network access accordingly.
3A 256-bit Pairwise Master Key (PMK) is derived from the authentication process by the RADIUS server and
the client.
4The RADIUS server distributes the PMK to the AP. The AP then sets up a key hierarchy and management
system, using the PMK to dynamically generate unique data encryption keys. The keys are used to
encrypt every data packet that is wirelessly communicated between the AP and the wireless clients.
Figure 168 WPA(2) with RADIUS Application Example
WPA(2)-PSK Application Example
A WPA(2)-PSK application looks as follows.
1First enter identical passwords into the AP and all wireless clients. The Pre-Shared Key (PSK) must consist
of between 8 and 63 ASCII characters or 64 hexadecimal characters (including spaces and symbols).
Appendix B Wireless LANs
XMG3512-B10A User’s Guide
265
2The AP checks each wireless client's password and allows it to join the network only if the password
matches.
3The AP and wireless clients generate a common PMK (Pairwise Master Key). The key itself is not sent over

Antenna Overview
An antenna couples RF signals onto air. A transmitter within a wireless device sends an RF signal to the
antenna, which propagates the signal through the air. The antenna also operates in reverse by
capturing RF signals from the air.
Positioning the antennas properly increases the range and coverage area of a wireless LAN.
Antenna Characteristics
Frequency
An antenna in the frequency of 2.4GHz (IEEE 802.11b and IEEE 802.11g) or 5GHz (IEEE 802.11a) is needed
to communicate efficiently in a wireless LAN
Radiation Pattern
A radiation pattern is a diagram that allows you to visualize the shape of the antenna’s coverage area.
Antenna Gain
Antenna gain, measured in dB (decibel), is the increase in coverage within the RF beam width. Higher
antenna gain improves the range of the signal for better communications.
For an indoor site, each 1 dB increase in antenna gain results in a range increase of approximately 2.5%.
For an unobstructed outdoor site, each 1dB increase in gain results in a range increase of approximately
5%. Actual results may vary depending on the network environment.
Antenna gain is sometimes specified in dBi, which is how much the antenna increases the signal power
compared to using an isotropic antenna. An isotropic antenna is a theoretical perfect antenna that
sends out radio signals equally well in all directions. dBi represents the true gain that the antenna
provides.
Types of Antennas for WLAN
There are two types of antennas used for wireless LAN applications.
• Omni-directional antennas send the RF signal out in all directions on a horizontal plane. The coverage
area is torus-shaped (like a donut) which makes these antennas ideal for a room environment. With a
wide coverage area, it is possible to make circular overlapping coverage areas with multiple access
points.
• Directional antennas concentrate the RF signal in a beam, like a flashlight does with the light from its
bulb. The angle of the beam determines the width of the coverage pattern. Angles typically range
from 20 degrees (very directional) to 120 degrees (less directional). Directional antennas are ideal for
hallways and outdoor point-to-point applications.
Positioning Antennas
In general, antennas should be mounted as high as practically possible and free of obstructions. In
point-to–point application, position both antennas at the same height and in a direct line of sight to
each other to attain the best performance.
Appendix B Wireless LANs
XMG3512-B10A User’s Guide
267
For omni-directional antennas mounted on a table, desk, and so on, point the antenna up. For omni-
directional antennas mounted on a wall or ceiling, point the antenna down. For a single AP application,
place omni-directional antennas as close to the center of the coverage area as possible.
For directional antennas, point the antenna in the direction of the desired coverage area.
