DISTANCE BETWEEN ACCESS POINTS
In environments where the number of wireless frequencies are limited, it can be beneficial to adjust the receiver
sensitivity of the LPS-20x. To make the adjustment, open the Wi-Fi page on the Wireless menu.
For most installations, the Large setting should be used. However, if you are installing multiple LPS-20xs and the
channels available to you do not provide enough separation, then reducing the receiver sensitivity can help you
reduce the amount of crosstalk between the LPS-20xs.
Another benefit to using reduced settings is that it will improve roaming performance. Client stations will switch
between LPS-20xs more frequently.
The Distance Between Access Points option provides the best performance
benefit when client stations are equipped with wireless adapters that are
configured with the same setting. However, not all manufacturers support this
setting.

CONFIGURING THE CONNECTION TO THE ACCESS CONTROLLER
The LPS-20x uses the services of an access controller to manage access to the public access network.
Unlike a traditional bridge which automatically forwards all traffic between ports, the LPS-20x features an intelligent
bridge which can apply filters to maintain the security of the network. When the security filters are active, the
LPS-20x only allows traffic to flow between itself and the access controller. This prevents wireless customers from
accessing resources on the backbone LAN that interconnects the LPS-20x and the access controller.
SECURITY FILTERS
To configure the connection to the access controller and enable the intelligent bridge, do the following:
1. On the main menu, click Security and then click Access controller. The Access controller configuration
page opens.
2. By default, the LPS-20x uses the default gateway as the access controller.
• If you are using static IP addressing, make sure that you set the default gateway on the LPS-20x to be the
access controller.
• If you are using a DHCP server on your network, make sure that it is configured to return the IP address of
the access controller as the default gateway. (The access controller is configured to do this by default.)
Alternately, you can specify the MAC address of the access controller.
3. Clear the security filters check box if you are connecting to a wired LAN (refer to
Connecting to a wired LAN on page 92).
4. Click Save.
ACCESS CONTROLLER SHARED SECRET
To maintain the security of network logins, the ADC access controller will only accept location-aware information
from a LPS-20x that has a matching shared secret to its own.

INTELLIGENT BRIDGE
The intelligent bridge uses filters to only allow traffic to flow between itself and an access controller. Traffic is filtered
as it is received by the upstream, downstream, or wireless ports. Each port has its own specific set of filters. Filters
apply only to data being received by the port (incoming traffic).
Upstream Port Filter (incoming traffic)
Accepted
• Any traffic from the access controller.
• Certain address management protocols (ARP, DHCP) regardless of their source address.
• HTTPS traffic regardless of its source address. (This permits local or remote management stations to
access the LPS-20x management tool.)
• Any traffic addressed to the LPS-20x.
• All broadcast traffic.
Blocked
• All other traffic is blocked. This includes NetBIOS traffic regardless of its source/destination address.
Downstream Port Filter (incoming traffic)
Accepted
• Any traffic addressed to the access controller. If you are using multiple daisy-chained LPS-20xs, all
should forward traffic to the same access controller.
• HTTPS traffic regardless of its source address. (This permits local or remote management stations to
access to the LPS-20x management tool.)
• Any traffic addressed to the LPS-20x.
• Certain address management protocols (ARP, DHCP) regardless of their source address.
• All broadcast traffic.
Blocked
• All other traffic is blocked. This includes NetBIOS traffic regardless of its source/destination address.
Wireless Port Filter (incoming traffic)
Accepted
• Any traffic addressed to the access controller.
• Any traffic addressed to the LPS-20x. Note that to access the management tool wirelessly, the appropriate security setting must be enabled on the Management tool page. Wireless client stations should have
the
LPS-20x configured as their default gateway. This ensures that outgoing traffic will be sent to the LPS-20x
which will then forward it to the access controller.
• Certain address management protocols (ARP, DHCP) regardless of their source address.
• All broadcast traffic.
Blocked
• All other traffic is blocked. This includes NetBIOS traffic regardless of its source/destination address.
HTTPS traffic not addressed to the LPS-20x is also blocked which means wireless client stations cannot
access the management tool on other LPS-20xs.

NETWORK PORT CONFIGURATION
The LPS-20x has three communication ports: upstream, downstream and wireless:
• Upstream - Used to connect the LPS-20x to the downstream port on another LPS-20x, to an access controller, or to a wired LAN.
• Downstream - Used to connect the LPS-20x to the upstream port on another LPS-20x or to a wired network.
• Wireless - Used to connect with wireless client stations.
All three ports are bridged and share the same IP address. By default, they are statically assigned to 192.168.1.1.

BRIDGE
The LPS-20x acts as a bridge between the wireless LAN and the wired LAN. By default, for security reasons, all
traffic forwarding between the two LANs is blocked. This means that although the wired LAN and the WLAN are on
the same segment, client stations cannot communicate with each other. You can enable communications by
disabling the intelligent bridge security filters. See Configuring the Connection to the Access Controller on page 79
and Disabling the Security Filters on page 93 for more details.
IP ADDRESSING
The LPS-20x makes the connection to the wired LAN via its downstream (LAN/Craft) port. The downstream port
shares the same IP address as the wireless port. This means that the wireless LAN and the wired LAN must always
be on the same subnet.

SERVICE SENSOR
The service sensor enables the LPS-20x to determine if access to the network or a particular server is available. If
not, the LPS-20x automatically shuts off its radio transmitter taking down the wireless cell.
This feature can be used to create backup operation of the network in case of equipment failure. For example, you
could install two LPS-20xs, each operating on a different channel within close proximity of one another. Each
LPS-20x would communicate with a different access controller. If one of the controllers goes down, the service
sensor will detect it and shut down the radio on the affected LPS-20x. Client stations connected to this LPS-20x will
automatically be transferred to the other LPS-20x with no interruption in service. This only works if both LPS-20xs
have the same SSID or are both configured to accept any network name (default setting).
The service sensor polls the target device approximately every half second.
CONFIGURATION PROCEDURE
1. On the main menu, click Security and then click Access controller. The Access controller configuration
page opens.
2. Configure the parameters as described in the section that follows.
3. Click Save when you are done.

SERVICE SENSOR PARAMETERS
Default Gateway
Select this option to poll the default gateway. If the gateway does not respond to the poll within 1 second, the radio is
turned off. This setting is not configurable. If Security filters are enabled, the default gateway must be the address
of the access controller.
Custom
Select this option to manually specify the IP address or domain name of the device to poll, the retry limit and timeout.
If you are using an ADC access controller, you can use the MAC authentication option to allow the LPS-20x to log
into the RADIUS server. This enables you to define an access list specifically for the LPS-20x that allows for access
to the required device.
Retry
Specify how many retries the LPS-20x will attempt when polling. When the retry limit is reached, the radio on the
LPS-20x is turned off. For example, if you set retry to 4, then the LPS-20x will make 5 attempts to poll the device at
the specified address. After the fifth failed poll, the radio will be turned off.
Timeout
Specify how long the LPS-20x will wait for a response to the poll before timing out.

LOCATION-AWARE AUTHENTICATION
This feature enables you to control logins to the public access network based on the wireless access point a
customer is connected to.
IMPORTANT
This feature can only be used when the LPS-20x is installed in conjunction with an access
controller.
This feature does not support 802.1x customers and devices using MAC-based authentication.
HOW IT WORKS
When a customer attempts to login to the public access network, the access controller sets the Called-Station-ID in
the RADIUS access request to the MAC address of the LPS-20x wireless port the customer is associated with. For
more information, see the Administrator’s Guide for the access controller.

WIRELESS BRIDGING
OVERVIEW
The wireless bridging feature enables you to use the wireless radio to create point-to-point wireless links to other
access points (Figure 22). Each LPS-20x can support up to six wireless bridges, which can operate at the same time
as the network serving wireless customers. Wireless bridging provides an effective solution for extending wireless
coverage in situations where it may be impractical or expensive to install cabling to a wireless access point.

WIRELESS NEIGHBORHOOD
The wireless neighborhood feature enables you to view a list of all authorized and unauthorized access points that
are operating nearby. At a preset interval, the LPS-20x automatically scans all operating frequencies to identify
active access points. The result of this scan is presented in the All access points list.
To identify unauthorized access points, the LPS-20x compares the MAC address of each discovered access point
against the list of authorized access points (which you must define). If the discovered access point does not appear
in the list, it is displayed in the Unauthorized access points list.
1. On the Wireless menu, click Neighborhood. The Neighborhood page opens.

Edit this list so that it contains only authorized access points and save it. Then specify its address for the list of
authorized access point parameters.
Field Descriptions
• MAC Address: MAC Address of the access point
• SSID: SSID assigned to the access point
• Status: Indicates if the unit is functioning properly
• Channel: Channel the access point is operating on
• Signal: Signal Strength
• Noise: Amount of noise
• SNP: Signal to noise ratio
• Info: Additional information about the access point, such as:
– WEP: Some type of security (like WEP) is enabled on the acces point
– ESS: Operating in access point mode
– IBSS: Operating in Ad-Hoc mode
VLAN SUPPORT
The LPS-20x provides a robust and flexible VLAN implementation. VLANs can be assigned in one of three ways:
• Default VLAN
• Per-SSID VALN
• Per-User VLAN
DEFAULT VLAN
The LAN port can be configured with a default VLAN setting. Any outgoing traffic on the LAN port that is not tagged
with a VLAN ID will receive the default ID. The default VLAN can be restricted to carry managment traffic only. This
includes:
• all traffic that is exchanged with the access controller
• all traffic exchanged with external RADIUS servers
• HTTPS sessions established by administrators to the management tool
• incoming/outgoing SNMP traffic
• DNS requests/replies

PER-SSID VLAN
Each wireless profile can be mapped to its own VLAN. Wireless clients that connect to a profile with VLAN support
are bridged to the appropriate VLAN via the LPS-20x’s LAN port. Address allocation and security measures are the
responsibility of the target network.
IMPORTANT
Per-SSID VLANs cannot have the same VLAN ID as the default VLAN ID assigned to the LAN port.
PER-USER VLAN
VLANs can also be assigned on a per-customer basis by setting a special ADC attribute in a customer’s RADIUS
account. The only restriction is that a customer cannot be assigned to a VLAN that is already mapped to the LAN
port.
To use this feature, the LPS-20x must be connected to a ADC access controller. Consult the administrator guide for
more information.
VLAN PRIORITY
The VLAN assigned by RADIUS on a per-user basis always overrides the VLAN assigned by an SSID and the
default VLAN. For example, a wireless station could be associated with an SSID that is configured for VLAN 30, but
after logging in, RADIUS could override this setting by assigning VLAN 40.

infrastructure with complete security.
How it works
The wireless network is split into two WLANs: public and private (Figure 23).
• Wireless users on the public WLAN are mapped to the access controller via VLAN 60.

VLAN STATUS
Use the VLAN option on the Status menu to determine the status of the virtual LAN.
WIRELESS CLIENT STATION PARAMETERS
Mac address
The Ethernet address of client station(s) that are associated to the AP.
SSID
The SSID that the client station(s) is associated with.
Association time
Indicates how long the client station has been associated with the LPS-20x.
Authorized
Applies to client stations using 802.1x only. A value of “Yes” indicates that 802.1x authentication was successful. A
value of “No” indicates that 802.1x authentication was unsuccessful. If 802.1x support is not enabled on the LPS20x, this field shows “yes”.
Signal
Indicates the strength of the radio signal received from the client stations. Signal strength is expressed in dBm. The
higher the number, the stronger the signal.
Noise
Indicates how much background noise exists in the signal path between client stations and the LPS-20x. Noise is
expressed in dBm. The lower (more negative) the value, the weaker the noise.
SNR
Indicates the relative strength of client station radio signals versus the radio interference (noise) in the radio signal
path. In most environments, SNR is a good indicator for the quality of the radio link between the client stations and
the LPS-20x. A higher SNR value means a better quality radio link.

WEP SECURITY
Wired equivalent privacy (WEP) provides protection for wireless traffic by encrypting all transmissions. Multiple keys
can be defined allowing stations to rotate key usage for enhanced security.
WARNING
ADC does not recommend the use of WEP alone for the creation of secure wireless networks.
CONFIGURATION PROCEDURE
1. On the main menu, click Wireless. The Wireless configuration page opens.
2. Check the wireless protection box.
3. In the Wireless protection box, choose WEP. The following parameters are displayed:

WIRELESS PROTECTION PARAMETER
The parameters that are visible depend on the settings you make for the Use dynamic key rotation.
Keys 1, 2, 3, 4
The number of characters you specify for a key determines the level of encryption the LPS-20x will provide.
• For 40-bit encryption, specify 5 ASCII characters or 10 HEX digits.
• For 128-bit encryption, specify 13 ASCII characters or 26 HEX digits.
When encryption is enabled, wireless stations that do not support encryption cannot communicate with the
LPS-20x. The definition for each encryption key must be the same on the LPS-20x and all client stations. Keys must
also be in the same position. For example, if you are using key 3 to encrypt transmissions, then each client station
must also use key 3 to communicate with the LPS-20x.
Transmission Key
Select the key the LPS-20x will use to encrypt transmitted data. All four keys are used to decrypt received data.
Key Format
Select the following format you use to specify the encryption keys:
ASCII
ASCII keys are much weaker than carefully chosen HEX keys. You can include ASCII characters between 32 and
126, inclusive, in the key. However, note that not all client station support non-alphanumeric characters such as
spaces, punctuation, or special symbols in the key.
HEX
Your keys should only include the following digits: 0-9; A, B, C, D, E, F (not case sensitive)

WIRELESS PROTECTION PARAMETER
The parameters that are visible depend on the settings you make for the Use dynamic key rotation.
Key Source
This option determines how the TKIP keys are generated.
RADIUS: The LPS-20x obtains the MPPE key from the RADIUS server. This is a dynamic key that changes each
time the user logs in and is authenticated. The MPPE key is used to generate the TKIP keys that encrypt the
wireless data stream. Select the appropriate RADIUS server.
WPA sessions are terminated by the LPS-20x. This means that the LPS-20x handles all authentication tasks and
must communicate with the RADIUS server or access controller to validate login credentials. The LPS-20x sends
this authentication traffic on the downstream port. Therefore, the RADIUS server or access controller must be
reachable via this port.
Preshared Key: The LPS-20x uses the key you specify in the Key field to generate the TKIP keys that encrypt the
wireless data stream. Since this is a static key, it is not as secure as the RADIUS option. Specify a key that is
between 8 and 64 characters in length. It is recommended that the preshared key be at least 20 characters long,
and be a mix of letters and numbers.
RADIUS Profile
Only valid value is Access Controller.

WIRELESS PROTECTION PARAMETER
This option enables support for users with 802.1x client software. The LPS-20x supports 802.1x client software that
uses EAP-TLS, EAP-TTLS, and PEAP.
Note that all authentication tasks are handled by the LPS-20x and not the wireless client station. This means that the
RADIUS server must be reachable via the downstream port.
IMPORTANT
802.1x sessions are terminated by the LPS-20x. This means that the LPS-20x handles all
authentication tasks and must communicate with the RADIUS server to validate login credentials.
The LPS-20x sends this authentication traffic on the internet port. Therefore, the RADIUS server
or access controller must be reachable via this port.
RADIUS profile
Communications with the RADIUS server is handled via the access controller. This setting cannot be changed.
WEP encryption
Enable the use of dynamic WEP keys for all 802.1x sessions. Dynamic key rotation occurs on key 1, which is the
broadcast key. Key 0 is the pairwise key. It is automatically generated by the LPS-20x.
Key length and key change interval are set in the Dynamic keys box.

SECURITY RADIUS – ADD NEW PROFILE
Each RADIUS profile defines the settings for a RADIUS client connection. To support a client connection, you must
create a client account (e.g., RAS account) on the RADIUS server. The settings for the account must match the
profile settings you define on the LPS-20x.
For backup redundancy, each profile supports a primary and secondary server. The LPS-20x will function with any
RADIUS server that supports RFC 2865 and RFC 2866. Authentication occurs via EAP-MDS, CHAP, MSCHAP v1/
v2 or PAP. To edit a profile, click on its name.
Only management users can be authenticated directly with RADIUS servers. For clients to be
authenticated, the LPS-20x must have security filters enabled and an access controller (e.g., LPX-21x)
must be accessible.

PROFILE NAME PARAMETER
Specify the name to identify the profile.
SETTING PARAMETERS
Authentication Port
Specify the port to use for authentication. By default, RADIUS servers use port 1812.
Accounting Port
Specify the port to use for accounting. By default, RADIUS servers use port 1813.
Retry Interval
Controls the retry interval (in seconds) for access and accounting requests that time-out. If no reply is received
within this interval, the LPS-20x switches between the primary and secondary RADIUS servers (if defined). If a reply
is received after the interval expires, it is ignored. This parameter applies to access and accounting requests
generated by the following:
• administrator logins to the management tool
• customer logins via HTML
• MAC-based authentication of devices
• authentication of the LPS-20x
The maximum number of retries can be determined as follows:
• HTML-based Logins: The number of retries is calculated by taking the setting for HTML-based logins
Authentication Timeout parameter and dividing it by the value of this parameter. The default settings
result in
four retries (40/10).
• MAC-based and LPS-20x authentication: Number of retries is infinite.
• 802.1x authentication: Retries are controlled by the 802.1x client software.
Authentication Method
Choose the default authentication method the LPS-20x will use when exchanging authentication packets with the
primary/secondary RADIUS server defined for this profile.
For 802.1x users, the authentication method is always determined by the 802.1x client software and is not controlled
by the setting.
If traffic between the LPS-20x and the RADIUS server is not protected by a VPN, it is recommended that you use
EAP-MD5 or MSCHAP V2 if supported by your RADIUS server. (PAP, MSCHAP V1 and CHAP are less secure
protocols.)
NAS Id
Specify the network access server ID you want to use for the LPS-20x. By default, the serial number of the LPS-20x
is used. The LPS-20x includes the NAS-ID attribute in all packets that it sends to the RADIUS server.

Always Try Primary Server First
Set this option to force the LPS-20x to contact the primary server first. Otherwise, the LPS-20x sends the first
RADIUS access request to the last known RADIUS server that replied to any previous RADIUS access request. If
the request times out, the next request is sent to the other RADIUS server (if defined).
For example, assume that the primary RADIUS server was not reachable and that the secondary server responded
to the last RADIUS access request. When a new authentication request is received, the LPS-20x sends the first
RADIUS access request to the secondary RADIUS server. If it does not reply, the RADIUS access request is
retransmitted to the primary RADIUS server. The LPS-20x always alternate between the two servers (when
configured).
PRIMARY RADIUS SERVER
Server Address
Specify the IP address of the RADIUS server.
Secret/Confirm Secret
Specify the secret (password) that the LPS-20x will use when communicating with the RADIUS server. The shared
secrets is used to authenticate all packets exchanged with the server to prove that they originate from a valid/trusted
source.
SECONDARY RADIUS SERVER (OPTIONAL)
Server Address
Specify the IP address of the RADIUS server.
Secret/Confirm Secret
Specify the secret (password) that the LPS-20x will use when communicating with the RADIUS server. The shared

SSL CERTIFICATES
This section explains how to create and install SSL certificates to secure communications with the LPS-20x.
OVERVIEW OF SSL CERTIFICATES
The only way to securely access a web server is to encrypt the data stream that is exchanged between the browser
and the web server. This ensures that if data is intercepted by a malicious third-party using a network analyzer on
the LAN or the Internet, it will be difficult or impossible for the data to be deciphered.
However, encryption does not solve another important security issue, namely how the identity of a web server can
be validated before a connection to it is established. The solution to this problem is provided by digital certificates.
A digital certificate is a collection of information about a web server digitally signed by a certificate authority. A
certificate authority is by definition an entity that can be trusted. It may be an entity in your organization responsible
for issuing certificates, a commercial certificate authority such as Thawte, Entrust or even yourself.
SSL is the standard for creating a secure encrypted connection between a web browser and a web server. SSL
relies on the exchange of digital certificates which provide the means for the web server and browser to authenticate
each other.
SSL AUTHENTICATION
The following sequence of steps illustrates how an SSL session is established.
1. A web browser attempts to open a web page via HTTPS.
2. The web server sends its digital certificate (as well as information needed to establish the SSL connection)
to the web browser. The certificate is signed using the private key of a certificate authority (CA). This is
usually a well known commercial entity.
3. The web browser attempts to validate the web server’s certificate. This happens as follows:
• The web browser checks that the server’s certificate has not expired. The certificate will contain the certificate’s validity period which can be compared to the current date.
• The web browser may be configured to check that the certificate is not in a Certificate Revocation List
maintained by the entity that issued the certificate.
• The web browser checks its internal list of trusted CAs to find the one that signed the web server’s certificate. Using the public key of this CA (which is also stored in the web browser), the web browser validates
the authenticity of the web server’s digital signature. This is possible because the web server’s certificate
is signed using the CA’s private key.
• The web browser extracts the domain name of the web server from the certificate. (When the certificate
was registered, this domain name was associated with the IP address of the LPS-20x’s Internet port.) It
then compares this against the domain name of the web server.
4. The web browser and the web server agree on a symmetric key to encrypt the SSL connection.
5. The SSL connection is started.
The host name in the currently installed SSL certificate is automatically assigned as the domain name of the
LPS-20x. The factory default SSL certificate that is installed on the LPS-20x has the host name wireless.adc.com.
You do not have to add this name to your DNS server for it to be resolved. The LPS-20x intercepts all DNS requests
it receives on the wireless or LAN ports. It resolves any request that matches the certificate host name by returning
the IP address assigned to the wireless port. All other DNS requests are forwarded to the appropriate DNS servers
as configured on the Network > DNS page. To summarize, this means that by default, any DNS request by a client
station on the wireless or LAN ports that matches wireless.adc.com will return the IP address of the LPS-20x’s
wireless port.

ABOUT CERTIFICATE WARNING MESSAGES
The default certificate installed on the LPS-20x is not registered with an authority certificate. It is a self-signed
certificate which is attached to the default IP address (192.168.1.1) for the LPS-20x.
This results in the following warning message each time a web browser attempts to validate the certificate.
There are three types of possible warnings in the Security Alert:
1. The security certificate was issued by a company you have not chosen to trust. This indicates that your
browser has no knowledge of the certificate and treats it as if it cannot be trusted. The warning is caused by
not having a CA certificate in the browser that can validate the certificate provided by the LPs-20x. To eliminate this warning message, you can install a new certificate as described in Installing a new SSL certificate
on page 141.
2. The Security certificate date is valid. Signifies that the operating system's date is within the range of beginning and end dates specified in the security certificate. Certificates have a limited lifetime and must be
renewed and replaced before they expire or else warnings will appear in the browser.
3. The security certificate has a valid name. This refers to the domain name listed in the "subject" field of the
security certificate that matches the domain name of the URL that you're attempting to go to. By default,
the name in the "subject" field of the certificate installed in the LPs-20x also becomes the domain name of
the LPs-20x and is resolved by the LPs-20x itself.
Once you comply with all three criteria, client stations will no longer get a certificate warning in their browser.

STEP 1: CREATING SSL CERTIFICATES
There are three ways to create a digital certificate:
1. Obtain a certificate from a recognized certificate authority: This is the best option, since it ensures that your
certificate can be validated by any web browser. A number of companies offer this service for a nominal
charge. These include: Thawte, Verisign, and Entrust.
2. Become a CA and issue your own certificate: You can become your own CA and create as many certificates as you require. However, since your CA will not be included in the internal list of trusted CAs maintained by most browsers, customers will get a security alert until they add your CA to their browser.
3. Create a self-signed certificate: This is the least secure method since the certificate is signed using the private key of the server rather than a CA. Self-signed certificates should generally be used for testing purposes only.
CERTIFICATE TOOLS
Digital certificates can be created/managed with a variety of tools. The examples in this section use the OpenSSL
tools and components included with the ADC Backend archive. You should download and install these items as
follows:
1. Download the Backend sample archive (refer to Product Support on page 177).
2. Download openssl-0.9.7c-win32-bin.zip from http://curl.haxx.se/download.html > OpenSSL Library
Packages.
3. Open a command prompt and create the following folder on your computer:
c:\certificates and c:\certificates\ca\newcerts
4. Extract openssl-0.9.7c-win32-bin.zip into c:\certificates.
5. Extract the contents of the certificates folder in the Backend archive into c:\certificates.
You are now ready to execute the following examples.
OBTAINING A REGISTERED CERTIFICATE
This example illustrates how to create a certificate request and send it to a certificate authority to obtain a registered
public certificate.
The benefit of using a registered certificate is that the public key for these CAs is included by default in most web
browsers and eliminates warning message pop-ups.
For the purpose of this example:
• the certificate will be requested for the domain name: www.company.com.
• the secret password used to protect the key is your_password.
1. Open a Windows command-line session.
2. Go to the directory where you installed the certificate tools. This example assumes c:\certificates.
3. Execute the command: newreq domain_name
For example:
C:\certificates\>newreq www.company.com
You will now be prompted for a password
that will protect the new private key.

At this stage, two files have been created in C:\certificates:
• www.company.com.key: This file contains the private key for the server.
• www.company.com.req: This file contains the certificate request.
Next, send the certificate request to a Trusted Certificate Authority to obtain a public key certificate from the CA. The
certificate file will be protected by the password you specified.
BECOMING A PRIVATE CA
This procedure enables you to sign your web server certificates using your own private key. Users who trust you will
be able to trust the certificates you have signed, providing that they have your public key certificate.
Creating the CA certificates
You will be asked for a password to protect the new private key, which will be the private key for your own Certificate
Authority.
IMPORTANT
This password will be required when signing subsequent certificates.
Ideally, the private key should be handled as one of your corporate secrets and should be in a safe location
accessible to the person responsible for signing the certificates.
For the purposes of this example:
• the certificate will be requested for the domain name: CompanyCA
• the secret password used to protect the key is CA_key_password
1. Open a Windows command-line session.
2. Go to the directory where you installed the certificate tools. This example assumes c:\certificates.
3. Execute the command: newca CompanyCA

-----END CERTIFICATE----At this stage, two files have been created in c:\certificates:
• CompanyCA.key, which contains the private key for your new Certificate Authority.
• CompanyCA.pem, which contains the X.509 certificate for your Certificate Authority’s public key.
These two files have been respectively copied into:
C:\certificates\CA\private\CAkey.pem
and

Creating the web server certificates
Once you have created the CA certificates, you can use them to create certificates for your LPS-20x or web server.
1. Open a Windows command-line session.
2. Go to the directory where you installed the certificate tools. This example assumes c:\certificates.
3. Execute the command: newcert domain_name
C:\certificates\>newcert www.company.com

CREATING A SELF-SIGNED CERTIFICATE
If you decide to use this option, there is no need for a certificate authority. This limits the effectiveness of the
certificate since it is signed using the private key of the server.
For the purposes of this example:
• the certificate will be requested for the domain name: www.yourserver.com
• the secret password used to protect the key is your_password
1. Open a Windows command-line session.
2. Go to the directory where you installed the certificate tools. This example assumes c:\certificates.
3. Execute the command: newselfcert domain_name.
C:\certificates>newselfcert www.company.com
You will now be prompted for a password
that will protect the new private key.

STEP 2: PREPARING THE CERTIFICATE CHAIN
When a web browser connects to the LPS-20x using SSL, the LPS-20x only sends its own SSL certificate to the
browser. This means that if the certificate has been signed by an intermediate certificate authority, and if the web
browser only knows about the root certificate authority that signed the Public Key Certificate of the Intermediate
certificate authority, the web browser will not get the whole certificate chain it needs to validate the identity of the
LPS-20x.
This does not apply when using self-signed certificates, since these certificates implicitly contain the whole
chain.
To resolve this problem, all the public key certificates must be appended to the certificate (www.company.com.pem
file, for example) in base64 format.
For example, if the LPS-20x certificate has been signed by an intermediate CA (CA2), and if the public key
certificate for CA2 was signed by CA1 root CA, the following certificates should be appended to the file
www.company.com.pem.
-----BEGIN CERTIFICATE----this is CA1 certificate
in BASE64/PEM encoding
-----END CERTIFICATE---------BEGIN CERTIFICATE----this is CA2 certificate
in BASE64/PEM encoding
-----END CERTIFICATE----When done, the www.company.com.pem file should look like this:
-----BEGIN CERTIFICATE----insert the www.company.com certificate in BASE64/PEM encoding
-----END CERTIFICATE---------BEGIN CERTIFICATE----insert the CA1 certificate in BASE64/PEM encoding
-----END CERTIFICATE---------BEGIN CERTIFICATE----insert the CA2 certificate in BASE64/PEM encoding
-----END CERTIFICATE-----

STEP 3: CONVERTING A CERTIFICATE TO PKCS #12 FORMAT
Before you can install a certificate on the LPS-20x, you need to convert it to PKCS #12 format. This can be done
with the openssl program pemtopkcs12. Execute the command:
pemtopkcs12 certificate
Replace certificate with the name of the certificate file.
Make sure that the .PEM and .KEY file are in the same folder and have the same name (with a different extension).
You will be prompted for two passwords:
• PEM pass phrase: Password used to protect the private key
• Export password: Password that will lock the PKCS#12 file. You will specify this password when you load
the certificate onto the LPS-20x.
For example:
pemtopkcs12 hotspot.adc.com
Loading 'screen' into random state - done
Enter PEM pass phrase:
Enter Export Password:
Verifying password - Enter Export Password:
This procedure will generate a file named .pcs12 file that contains both the private key and public key certificate.
This file can now be installed on the LPS-20x.

STEP 4: INSTALLING A NEW SSL CERTIFICATE
Use this procedure to replace the SSL certificate that ships with the LPS-20x with one of your own. This certificate is
used when validating user logins to the management tool via SSL.
Before you can install a new SSL certificate, make sure that it conforms to the following:
• It must be in PKCS #12 format. Refer to Step 3: Converting a Certificate to PKCS #12 Format on page
156 for
instructions on how to do this.
• It must contain a private key. (The password is used to access the private key.)
• It must not have a name that is an IP address. The name should be a domain name containing at least
one dot. If you try to add a certificate with an invalid name, the default certificate is restored.
• It must contain the entire certificate chain if signed by an intermediate certificate authority.
• It must not have a “_” in its name.
The name in the certificate is automatically assigned as the domain name of the LPS-20x. The default certificate has
the name wireless.adc.com.
MANUAL INSTALLATION
To install a new SSL certificate, do the following:
1. Use your web browser to open the management tool.
2. On the Security menu, click Certificates.
3. In the Web server - SSL certificate box, specify the location of the new certificate and its password. If you
are using the certificate created by the example in this section:
– The certificate is located in: c:\certificates\www.company.com.pkcs12.
– The password is your_export_password.
4. Click install.

STEP 5: INSTALLING CERTIFICATES IN A BROWSER
If you are operating as your own certificate authority, installing a certificate signed by your own CA will still cause a
security warning to appear when customers open the LPS-20x’s Login page. This occurs because your CA is not
part of the group of well-known certificate authorities included with most browsers. This means customers will get a
security warning when establishing the SSL connection with the Login page.
To eliminate this warning message, customers must add the public key certificate for your CA to the list maintained
by their browsers.

THE CONFIGURATION FILE
This section provides an overview of the configuration file and explains how to edit it.
MANUALLY EDITING THE CONFIG FILE
The configuration file contains the settings for all customizable parameters on the LPS-20x. Almost all of these
parameters can be set using the web-based management tool. However, certain infrequently-used parameters can
only be set by manually editing the configuration file.
RETRIEVING/RESTORING THE CONFIGURATION FILE
To edit the configuration file, you must first retrieve it from the LPS-20x. Once edited, it then needs to be restored.
There are several ways to do this:
• The easiest way to accomplish both tasks is via the management tool. Use the Config file management
page on the Maintenance menu to download/upload the configuration file.
• HTTPS: The configuration file can be downloaded and uploaded via HTTPS. Use a tool like cURL to
make this easy. Refer to Configuration File Management on page 56 for details.
• Many configuration file parameters are also accessible via SNMP. For details, see the comments inside
the Colubris-Maintenance-MIB (refer to Product Support on page 177).
IMPORTANT
The local username and password for the administrator is not saved when you use the Backup
Configuration option. If you upload a configuration file, the old username and password are
therefore not updated.
If you upload a configuration file with an invalid structure, it is possible to put the LPS-20x into
an unstable state. To return to normal operation, do a factory reset.

Port to Trace
Choose the port to apply the trace to.
Destination
Select where the trace file will be stored/sent:
• Local: Trace file is stored on the LPS-20x. Size of the trace file is limited by available memory. When
space is exhausted, the trace is truncated.
• Remote URL: Specify the URL of the remote device to send the trace file to. Trace data is automatically
sent as it is gathered; therefore, there is no size limit to the trace. To avoid unnecessary bandwidth usage,
a filter should be used to restrict the trace.
• When using FTP://, the trace is saved in Etherneal PCAP format.
• When using HTTP://, the target server must be able to receive and save the file correctly. Server-side
scripts may be required to support this.
Timeout
Specify the amount of time the trace will capture data (in seconds). Once this limit is reached, the trace automatically
stops.
Number of Packets
Specify the maximum number of packets (IP datagrams) the trace should capture. Once this limit is reached, the
trace automatically stops.
Packet Size
Specify the maximum number of bytes to capture for each packet. The rest of the data is discarded.

Filter
Lets you specify a filter expression which controls which packets will be captured by the trace. Leave the filter blank
to trace all packets. The filter expression has the same format and behavior as the expression parameter used by
the well-known TCPDUMP command. Table 16 is a summary of syntax of this command. For more detailed
information, consult one of the many TCPDUMP pages available on the Internet. The filter consists of one or more
primitives. Primitives usually consist of a qualifier followed by an id (number or name).
Table 16. Syntax
Qualifier
type
Description
Possible values are: host, net, port.
If you do not specify a type qualifier, then host is assumed.
Examples:
host 192.168.30.57
net 128.3
port 20
dir
Identifies transfer direction. Possible values are: src, dst, src or dst, src and dst
If you do not specify a dir qualifier, then src or dst is assumed.
Examples:
src 192.168.30.57
dst net 128.3
src or dst port ftp-data
proto
Restricts the trace to a particular protocol. Possible values are: ether, ip, arp, rarp, tcp,
udp. If you do not specify a proto qualifier, then all protocols consistent with the supplied
type are assumed.
Examples:
src 192.168.30.57 (implies ip, arp or rarp)
net yahoo.com (implies ip, arp or rarp)
net yahoo.com and port 53 (implies tcp or udp on port 53)

SCP-LPS20x-011-012-01H
In addition to Table 16, there are some special “primitive” keywords that do not follow the pattern: gateway,
broadcast, less, greater and arithmetic expressions. For more detailed information, consult one of the many
TCPDUMP pages available on the Internet. More complex filter expressions are built up by using the words: “and”,
“or”, and “not” to combine primitives.
For Example:
host 192.168.30.57 and not port ftp and not port ftp-data
To save typing, identical qualifier lists can be omitted.
For Example:
tcp dst port ftp or ftp-data or domain
is exactly the same as
tcp dst port ftp or tcp dst port ftp-data or tcp dst port domain
The following examples show how to construct some basic trace filters.
src 192.168.30.57
src not 192.168.130.57
src or dst 192.168.30.57
src or dst net 192.168.130
tcp port 21 or tcp port 20 which is the same as tcp port 21 or 20
dst port 21 and tcp

EUROPE - EU DECLARATION OF CONFORMITY
This device is for indoor use only.
IMPORTANT
Users must select the proper country of operation when ordering to ensure wireless operational
settings conform to local regulations.
If more than one unit is deployed, users must ensure that the operating frequencies are spread
among different channels (according to channel availability).
USA - FEDERAL COMMUNICATIONS COMMISSION (FCC)
The LPS-20x complies with Part 15 of FCC Rules. Operation of the LPS-20x in a system is subject to the following
two conditions:
• This device may not cause harmful interference.
• This device must accept any interference that may cause undesired operation.
Caution: Exposure to Radio Frequency Radiation
The radiated output power of the LPS-20x is far below the FCC radio frequency exposure limits. Nevertheless, the
LPS-20x should be used in such a manner as to minimize the potential for human contact during normal operation.
When using this device in combination with ADC antenna products, a certain separation distance between the
antenna and nearby persons has to be kept to ensure RF exposure compliance.
Refer to the Regulatory Statements as identified in the documentation that comes with those products for additional
information.
When an external antenna is connected to the LPS-20x, it shall be placed in such a manner as to minimize the
potential for human contact during normal operation. To avoid the possibility of exceeding the FCC radio frequency
exposure limits, human proximity to the antenna shall not be less than 20 cm (8 inches) during normal operation.
When no external antenna is connected, the RF output power of the LPS-20x is far below the FCC radio frequency
exposure limits. Nevertheless, it is advised to use the LPS-20x in such a manner that human contact during normal
operation is minimized.

Interference Statement
The LPS-20x has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a
residential installation.
The LPS-20x generates, uses, and can radiate radio frequency energy. If not installed and used in accordance with
the instructions, it may cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation.
If the LPS-20x causes harmful interference to radio or television reception which can be determined by turning the
LPS-20x on and off, the user is encouraged to try and correct the interference by one or more of the following
measures:
• Reorient or relocate the receiving antenna.
• Increase the distance between the LPS-20x and the receiver.
• Connect the LPS-20x to an outlet on a circuit different from that which the receiver is connected
(if locally powered).
• Consult your dealer or an experienced radio/TV technician for help.
ADC is not responsible for any radio or television interference caused by unauthorized modification of the LPS-20x,
or the substitution or attachment of connecting cables and equipment other than that specified by ADC.
The correction of interference caused by such unauthorized modification, substitution or attachment is the
responsibility of the user.
HEALTH INFORMATION
The LPS-20x, like other radio devices, emits radio frequency electromagnetic energy. The level of energy emitted by
the LPS-20x is much less than the electromagnetic energy emitted by other wireless devices, such as mobile
phones.
Because the LPS-20x operates within the guidelines found in radio frequency safety standards and
recommendations, ADC believes that the LPS-20x is safe for use by consumers. These standards and
recommendations reflect the consensus of the scientific community and result from deliberations of panels and
committees of scientists who continually review and interpret the extensive research literature.
In some situations or environments, the use of the LPS-20x may be restricted by the proprietor of the building or
responsible representatives of the organization. These situations may, for example, include:
• Using the LPS-20x
In any environment where the risk of interference to other devices or services is perceived or identified as harmful.
If you are uncertain of the policy that applies to the use of wireless devices in a specific organization or environment
(e.g. airports), you are encouraged to ask for authorization to use the LPS-20x prior to turning it on.
