Radio and TV Interference

The LRA2900A Series generates and uses radio frequency energy, and if not installed and used properly—that
is, in strict accordance with the manufacturer's instructions—may cause interference to radio and television
reception. The LRA2900A Series has been tested and found to comply with the limits for a Class A computing
device in accordance with the specifications in Subpart B of Part 15 of FCC rules, which are designed to pro­vide reasonable protection from such interference in a commercial installation. However, there is no guarantee
that interference will not occur in a particular installation. If the LRA2900A Series causes interference to radio
or television reception, which can be determined by disconnecting the cables, try to correct the interference by
one or more of the following measures: moving the computing equipment away from the receiver, re-orienting
the receiving antenna, and/or plugging the receiving equipment into a different AC outlet (such that the com­puting equipment and receiver are on different branches)

This device is not intended to be connected to the public tele­phone network in Europe.

Industry Canada Notice

The Canadian Department of Communications label identifies certified equipment. This certification means
that the equipment meets certain telecommunications network protective, operational and safety require­ments. The Department does not guarantee the equipment will operate to the user's satisfaction. Before install­ing this equipment, users should ensure that it is permissible to be connected to the facilities of the local
telecommunications company. The equipment must also be installed using an acceptable method of connec­tion. In some cases, the company’s inside wiring associated with a single line individual service may be
extended by means of a certified connector assembly (telephone extension cord). The customer should be
aware that compliance with the above condition may not prevent degradation of service in some situations.
Repairs to some certified equipment should be made by an authorized maintenance facility designated by the
supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give
the telecommunications company cause to request the user to disconnect the equipment. Users should ensure
for their own protection that the ground connections of the power utility, telephone lines and internal metallic
water pipe system, are connected together. This protection may be particularly important in rural areas

Users should not attempt to make such connections themselves,
but should contact appropriate electric inspection authority, or
electrician, as appropriate.

FCC Compliance

Introduction

You may configure the access server by using its internal HTTP/HTML Administration Pages. However, to
enter into the HTTP/HTML pages, you must first define the LAN Address Technique, LAN IP Address, and
LAN Subnet Mask for the access server. If you have not done so, please refer to the Getting Started Guide that
came with your access server.

Logging into the HTTP/HTML Administration Pages

To log into the HTTP/HTML Administration pages, you must enter the 4-octet Internet Protocol (IP) (for
example, http://your.server.ip.address) address as the Universal Resource Locator (URL) into a World-Wide Web
(WWW) browser. After you enter the IP address, the access server will ask for your user name and password as
shown in figure 1.

Figure 1. Access server login window

Your access server will accept the following default administrative passwords:

• superuser—this password carries full permission to change and view any parameters in the access server

• monitor—this password allows full viewing of any non-password oriented variables.

Note For security reasons, we recommend that you change these passwords

immediately after initial configuration.

HTTP/HTML and SNMP Object Format

In this document, we shall describe the variables found on each of the internal HTTP/HTML pages. This
description will include brief definitions of the Black Box Enterprise MIB or SNMP MIB II object identifiers
wherever applicable. The format of the variables will resemble figure 2.

Introduction

This chapter describes the HOME window—the first Administration Page that you see after logging into the
access server (see figure 3). From
base, save any system changes, or reset the system without power-cycling the server.

Note Clicking on the HOME link in the Configuration Menu pane will

return you to the

The

HOME window is divided into two panes: the Configuration Menu pane and the configuration/information

pane (see figure 3). The

Configuration Menu contains the links to the various access server subsystems, while

the configuration/information pane is where you can view status and other information, or make changes to
the system configuration. Unlike the Configuration Menu pane, which looks the same no matter which sub­system page you may move to, the configuration/information pane contents will change as you move from one
subsystem page to another.

HOME, you can monitor current system status, modify the Static User data-

HOME page from any other page.

Operating Status Variables

There are seven system variables which describe the immediate operating status access server. These variables
are shown in figure 4 and are described in the following sections.

Figure 4. STATUS menu

Active Calls (diActive)

This number, ranging from 0 to 60 displays the total number of calls being processed (connecting, dead,
authenticating, and so on) in the access server at the time the HOME page was displayed.

Peak Active Calls (diMaxActive)

The maximum number of active calls seen at one time since the access server was powered on.

Total Calls (diTotalCallAttempts)

The total number of calls attempted since the last boot of the box.

DSPs Not Working (dspFailed)

This number should always be zero. The DSPs in the access server are arranged as a resource pool and called
upon at ring-time. If a DSP fails to respond to the access server’s CPU, it is determined to have failed, at which
point the CPU will remove the DSP from the resource pool. If an incoming call attempts to access the failed
DSP, the RAS will answer, then terminate the call (to a person monitoring the failed call through a telephone
handset, he or she will hear only silence during the call, ending with a faint click as the call is terminated). One
symptom indicating that a DSP has failed is if the access server is not handling as many calls as it normally does.

Total DRAM Detected (boxDetectedMemory)

This number shows the total number of bits of installed and available DRAM.

Running Since Last Boot (sysUpTime)

This tells you how long the access server has been running since the it was last reset. It displays the number of
hours and rolls over after 1,193 hours (497 days).

Operating Status Variables 40

Immediate Actions

There are several immediate actions (see figure 5) which, when in superuser mode, will cause the access server
to operate according to the descriptions in the following sections.

Figure 5. Immediate Actions buttons

• Record Current Configuration —clicking this button causes the current configuration to be stored in

FLASH memory. Any changes made to the access server configuration are stored in non-volatile RAM. This
allows the user to set the box up with a running configuration before committing it to FLASH. Configura­tion changes become permanent when you select Record Current Configuration. You will lose all
changes not stored to FLASH the next time the access server is re-booted.

• Hard Reset—this button causes the access server to perform a cold restart. When you select Hard Reset,

the access server confirm that you want to execute this command. Then, the access server will disconnect all
current sessions, re-initialize the interfaces, and re-load configuration parameters from FLASH.

• Set Factory Default Configuration—this button clears out the configuration in FLASH and loads the

factory default parameters into FLASH memory. The factory default settings will not execute on the access
server until it is re-booted.

Note Set Factory Default Configuration will delete any routing infor-

mation, the access server’s Ethernet IP address, and any other site spe­cific settings made for your particular installation. You will have to re­enter the access server’s Ethernet IP address and netmask using the
front panel control port in order to use the HTTP/HTML Manage­ment pages.

4 • Alarms Model LRA2900A RAS Administrators’ Reference Guide

Introduction

The access server has an extensive alarm reporting system which enables users to configure, monitor, and test
major and minor alarms. The alarm system can be set to notify if equipment fails (for example, a power supply
failure) or if a T1/E1/PRI port malfunctions. There are 11 access server items that can be configured by the
user to generate alerts based on the condition of the access server.

Displaying the Alarms window

Click on Alarms under the Configuration Menu to display the Alarm System main window (figure 9).

Note The system administrator can manually generate a specific alarm for

testing purposes or clear the alarm counters from the main window.

47 Introduction

Figure 9. Alarms main window

Model LRA2900A RAS Administrators’ Reference Guide 4 • Alarms

The access server has three methods to notify of an alarm condition:

• Front panel LED—The front panel ALARM LED has three states that indicate the presence and severity of

an alarm. The states are:

- Off—No alarm present

- Solid—Minor alarm

- Flashing—Major alarm.

Note The POWER LED will flash if a power supply failure alarm is

present.

• Administration web page indication—The Alarms window of the administration page uses red highlighting

to indicate which items are in an alarm state (see figure 10).

Figure 10. Sample alarm indication

• SYSLOG/SNMP—For external notification, the access server can be configured to send a SYSLOG mes-

sage or an SNMP TRAP to an external management host. To configure the alarm response for either SNMP
Traps or SYSLOG messages, click on the

Alarm Response link (go to “Modify Response—Configuring the

alarm response system” on page 50).

Besides enabling a user to view current alarm status, manually generate an alarm as a test, and clear the alarm
time and alarm count variables, the Alarms main window also contains links to the following:

• Modify Response—Clicking on this link takes you to a window where you can change how the SYSLOG/

SNMP function notifies remote users of an alarm (see “Modify Response—Configuring the alarm response
system” on page 50)

• Modify Alarms—Clicking on this link takes you to a window where you can change how the access server

perceives the severity of each alarm (“Modify Alarms—Configuring alarm severity levels” on page 52)

Alarm Response Outputs

Alarm Response Outputs display the current settings for handling alarm notification via SYSLOG/SNMP mes­sages. To change how the SYSLOG/SNMP function notifies remote users of an alarm, refer to “Modify
Response—Configuring the alarm response system” on page 50.

Displaying the Alarms window 48

4 • Alarms Model LRA2900A RAS Administrators’ Reference Guide

Minor Alarm Syslog Priority (minSyslogPriority)

Displays the SYSLOG priority of the minor alarm SYSLOG message. If the minimum priority for SYSLOG
daemon (set under the System Log link) is less than this value, the SYSLOG daemon will receive the minor
alarm SYSLOG message.

Major Alarm Syslog Priority (majorSyslogPriority)

Displays the SYSLOG priority of the major alarm SYSLOG message. If the minimum priority for SYSLOG
daemon (set under the System Log link) is less than this value, the SYSLOG daemon will receive the major
alarm SYSLOG message.

Minor Alarm Trap IP (minorTrapIp)

Displays the IP address of a host system which is running a SNMP trap daemon. Minor alarm messages will be
sent to the system. If set to 0.0.0.0 then no trap message will be sent in response to a minor alarm

Major Alarm Trap IP (majorTrapIp)

Displays the IP address of a host system which is running a SNMP trap daemon. Major alarm messages will be
sent to the system. If set to 0.0.0.0 then no trap message will be sent in response to a major alarm

Clear All Alarms

Clicking on this button resets all alarms to a non-alarm condition. Clear All Alarms does the following for all
alarms: it resets the alarm, resets Alarm Time to 0.0 seconds, and resets the Alarm Count to 0.

Alarms

This portion of the Alarms main window displays the alarm status table, where you can view current alarm sta­tus, manually generate an alarm as a test, and clear the alarm time and alarm count variables.

Alarm ID

This number identifies the alarm item.

Alarm Name

The alarm items are grouped into two categories: Box and WAN trunk alarms. The Box group category lists
access server temperature and power supply status. The WAN category monitors the T1/E1/PRI ports for yel­low and red alarms.

Alarm Time

The Alarm Time column displays the number of seconds the alarm has been activated.

Alarm Count

The Alarm Count column indicates how many times the alarm has occurred since the last time alarms were
cleared. It is a useful tool for monitoring self-clearing alarms.

Generate Alarm

For testing purposes, clicking the Generate Alarm button next to each alarm name will cause that alarm con­dition to be activated, as if the actual alarm trigger had occurred.

49 Displaying the Alarms window

Model LRA2900A RAS Administrators’ Reference Guide 4 • Alarms

Clear Alarm

Clicking the Clear Alarm button resets the alarm to a non-alarm condition. Clear Alarm resets Alarm Time
to 0.0 seconds, and resets the Alarm Count to 0.

Modify Response—Configuring the alarm response system

The alarm response outputs only effect external notification via SYSLOG/SNMP as the front panel ALARM
LED and the web administration pages will always indicate an alarm condition. The following user configura­tion items can be set to permit external notification of access server alarm conditions:

Figure 11. Alarm Response System window

Minor Alarm Syslog Priority (minSyslogPriority)

Sets the SYSLOG priority of the minor alarm SYSLOG message. The higher the minimum priority for SYS­LOG daemon (set under the System Log link) is, the fewer non-essential messages will be sent to the SYSLOG
daemon with the alarm messages. The minor/major alarm SYSLOG priority must be set at least as high as min­imum priority for SYSLOG daemon for SYSLOG messages to be generated. PrioritySystem has the highest pri­ority; priorityVerbose the lowest priority.

• priorityVerbose(5)

• priorityDebug(10)

• priorityInfo(20)

• priorityOddity(40)

51 Modify Response—Configuring the alarm response system

Model LRA2900A RAS Administrators’ Reference Guide 4 • Alarms

Modify Alarms—Configuring alarm severity levels

The Modify Alarms window (see figure 12) is where you can set the severity level each alarm condition gener­ates and whether it can be a self-clearing condition.

Figure 12. Modify Alarms settings window

The following alarm items that can be configured to generate alarm conditions:

• Box: Over Temperature—An alarm will be triggered when the highest temperature (set under the System

link) exceeds 80°C.

• Box: Power Supply 1–2 Fail—An alarm will be triggered if power supply 1 or 2 fails.

• Box: Main and Fallback Clock Fail—An alarm will be triggered when either the main or fallback clock fail.

• WAN 1–4 Yellow Alarm—When a WAN port detects a yellow alarm condition, the specific WAN alarm

will be set.

• WAN 1–4 Red Alarm—When a WAN port detects a red alarm condition, the specific WAN alarm will be set.

Each alarm item can be set for one of the following severity levels:

• Ignore(0)—Do not generate an alarm

• Minor(1)—Generate a minor alarm that will not reset until the administrator manually clears it

• Major(2)—Generate a major alarm that will not reset until the administrator manually clears it

• MinorSelfClearing(3)—Generate a minor alarm that automatically clears if the alarm condition ceases

• MajorSelfClearing(4)—Generate a major alarm that automatically clears if the alarm condition ceases

Modify Alarms—Configuring alarm severity levels 52

4 • Alarms Model LRA2900A RAS Administrators’ Reference Guide

Note For maximum flexibility, defining what constitutes a major or minor

alarm is left up the administrator. Some examples of typical major
and minor include:

• Box Over-temperature—Major Alarm

• Power Supply Failure—Minor Alarm

• WAN Port Yellow Alarm—MajorSelfClearing

• WAN Port Red Alarm—MajorSelfClearing

Introduction

Use the Authentication pages to set up system security and to provide specific users with access to appropriate
network services. This section describes the authentication parameters. The access server uses static and/or
RADIUS authentication to decide which dial-in users can access the system (refer to Appendix A, “Supported
RADIUS Attributes” for a full list of RADIUS attributes).

Displaying the Authentication window

Do the following:

1. Click on

Authentication under the Configuration Menu (see figure 13).

55 Introduction

Figure 13. Authentication main screen

Model LRA2900A RAS Administrators’ Reference Guide 5 • Authentication

2. Select Modify to set up or change access server Authentication parameters.

The Statistics section

The Statistics section of the main Authentication screen lists running totals of statistics for RADIUS and Static
User logins gathered since the last access server reset.

Validated authentications (auAuthenticationsValidTotal)

The total number of validated authentications since the last access server reset.

Validated via primary server (auAuthenticationsValidPrimary)

The number of authentications validated by the primary RADIUS authentication server since the last access
server reset.

Validated via secondary server (auAuthenticationsValidSecondary)

The number of authentications validated by the secondary RADIUS authentication server since the last access
server reset.

Validated via static database (auAuthenticationsValidStatic)

The number of authentications validated by the Static User database since the last access server reset.

Denied authentications (auAuthenticationsDenied)

The total number of authentication attempts requested but denied since the last access server reset.

Primary server retries (auPrimaryServerRetrys)

The number of times the access server needed to make subsequent requests for a call to the primary RADIUS
authentication server.

Secondary server retries (auSecondaryServerRetrys)

The number of times the access server needed to make subsequent requests for a call to the secondary RADIUS
authentication server.

Accounting server retries (auAccountingServerRetrys)

The number of times the access server needed to make subsequent accounting requests for a call.

Primary server timeouts (auPrimaryServerTimeouts)

The total number of authentication timeouts by the primary RADIUS authentication server.

Secondary server timeouts (auSecondaryServerTimeouts)

The total number of authentication timeouts by the secondary RADIUS authentication server.

Accounting server timeouts (auAccountingServerTimeouts)

The total number of accounting timeouts by the primary RADIUS accounting server.

Maximum Response Time

The maximum time it has taken for authentication to be completed since the server rebooted.

The Statistics section 56

5 • Authentication Model LRA2900A RAS Administrators’ Reference Guide

Last Response Time

The time taken for the last authentication to be completed.

Setting Up Authentication

After selecting Modify from the main Authentication screen, you may set up or change authentication parame­ters for both RADIUS users and Static users. After configuring the Validation method (see “Validation (auVal­idation)” below), configure the additional parameters as shown in figure 14 to configure RADIUS parameters.
See “Static User Authentication” on page 59 to set up Static users.

Figure 14. Authentication Configuration screen

Validation (auValidation)

Selects how the access server will authenticate an incoming call. Select from:

• No Validation(0)—Select this to allow un-authenticated calls into the access server, and on to your LAN,

using the default service.

• static Users(1)—Use the access server internal user database only to authenticate. Static users are simply

users and passwords entered into the access server’s internal users database.

• radius Users(2)—Use RADIUS to authenticate and provision user services. RADIUS is a client-server sys-

tem developed to manage the flexible requirements of remote dial-in users. The RADIUS protocol is speci­fied under RFC 2138 for authentication and RFC 2139 for accounting. RADIUS servers are available as
freeware for most computer platforms and is an excellent method for managing user dial-in security. Any
RADIUS entries will require an associated server to process authentication requests from the access server or

57 Setting Up Authentication

Model LRA2900A RAS Administrators’ Reference Guide 5 • Authentication

the access server will reject users access. For more information about RADIUS, see RADIUS User Authenti­cation, below.

• tacacs Users(3)—This feature is not currently available

• static Then RADIUS(4)—Check the internal user database first, if no match is found, then use RADIUS to

authenticate and provision user services.

• static Then Tacacs(5)— Check the internal user database first, if no match is found, then use TACACS to

authenticate and provision user services. Not currently implemented.

Note The following options apply only when using an external authentica-

tion server.

Host Address (auHostAddress)

Tells the access server the IP address of the primary external authentication server. This must be the IP address
as the access server will not resolve a Fully Qualified Domain Name.

Secondary Host Address (auSecondaryHostAddress)

When using a remote authentication server (RADIUS) this variable provides an alternative server IP address.

Host Port (auHostPort)

This variable tells the access server which UDP port to use when connecting to the host specified in the Host
Address variable. The RADIUS standard, as per RFC 2138, specifies port 1812 for RADIUS authentication.
Some older installations of RADIUS use port 1645.

Timeout (auTimeout)

This option specifies the time, in seconds, before the access server will retransmit an authentication request to
an external authentication server.

Retries (auRetries)

This option specifies the number of times the access server will resend an authentication request to a RADIUS
server after a TIMEOUT occurs. If this number is exceeded then the secondary host will be tried. If this num­ber is exceeded by the secondary host, the user will be rejected.

Secret (auSecret)

The Secret variable sets the shared secret between the authentication client (access server) and the authentica­tion server (RADIUS). It is used to encrypt an authentication request and to decrypt an incoming reply from
the server. The secret on the access server and the RADIUS server must match and must be 15 or fewer print­able, non space, ASCII characters.

Note The same secret word must used on the access server and in the

RADIUS clients file.

NAS Identifier (auNASIdentifier)

This variable is used to identify the access server to the remote authentication server. If this option is blank,
then the access server will use it’s IP address to identify itself to the remote server. It does this by using the NAS­IP-Address attribute instead of the NAS-Identifier attribute.

Setting Up Authentication 58

5 • Authentication Model LRA2900A RAS Administrators’ Reference Guide

Accounting Address (auAcctAddress)

This is the IP address of the accounting server. RADIUS also allows for the recording of accounting informa­tion.

Secondary Accounting Address (auSecondaryAcctAddress)

When using a remote accounting server (such as RADIUS Accounting) this variable provides the IP address of
the accounting server.

Accounting Port (auAcctPort)

This is the UDP port on the accounting server specified in Acct Address that the access server should use to
transfer accounting information. RFC 2139 states that port 1813 is the standard RADIUS accounting port.
Some older implementations of RADIUS use port 1646 as the accounting port.

Accounting Enable (auAccountingEnable)

This is a switch that allows the enabling or disabling the reporting of accounting information on the access
server. The following options are available:

• enableAccounting—Begin accounting of RADIUS authenticated users.

• disableAccounting—Disable the accounting feature.

• enableAccounting-no validation—When a response is received from either the authentication or the

accounting server it is validated using the defined secret. If the secret does not match, the reply packet is
dropped just as if it never existed.

Early versions of the Livingston RADIUS server used a method for encoding the accounting reply packet
that was incorrect. Accounting replies from these servers would therefore be dropped because they could not
be authenticated, eventually resulting in timeouts and shutting the call down with the reason authenAccoun-
tingTimeout. As a workaround for this issue, the state enableAccountingNoValidation—which does not check
for valid encoding on the accounting reply packet—was added as an option.

Radius Packet Format (auRadiusPacketFormat)

The following options are available:

• fullrfcPacket—The accept request packet includes Calling-Station-Id and Service-Type RADIUS attributes.

• minimumrfcPacket—This setting does not include Calling-Station-Id and Service-Type RADIUS

attributes.

Static User Authentication

To view or modify the static users in the internal user database, click on Authentication in the Configura-

tion Menu. The Authentication window displays. Scroll down until Static User Identification is dis-

played (see figure 15).

Static users consist of usernames and passwords entered into the access server’s internal users database. You can
have up to 111 static users in the access server database.

You must have superuser-level access to make changes to the static users database.

The following sections describe each of the variables found in the

59 Static User Authentication

Static User Identification section.

Identifies the entry in the table of users. For the next user, select the next unused number. If you select a num­ber that is already displayed in the Static User Identification table, you will overwrite a current entry in user
database.

Username (suUsername)

This is a unique name, to be provided at login time.

Note There is a 19-character limit on the username length.

Password (suPassword)

This is the password that is provided at login time along with the username.

Service (suService)

This option instructs the access server on how to service the incoming call. Select from:

• default—This is the default service as specified under Dial-In (see Chapter 7, “Dial In”). We recommend

that you select default.

• admin—Not currently implemented.

• monitor—Not currently implemented.

• rlogin—Causes the access server to rlogin into another host. See “Service IP (suServiceIP)” on page 62 for

information on configuring the remote host IP addresss.

• telnet—Causes the access server to telnet into another host.

• tcpraw—All 8 bits are passed unchecked and unaltered.

• ppp—Access server will try to negotiate a PPP session.

• cppp—Access server will try to negotiate a Compressed-PPP session.

Adding Static Users 60

5 • Authentication Model LRA2900A RAS Administrators’ Reference Guide

Note If a user attempts to login in using a different service than the one he

or she has been provided, the access server will reject the user. The
exception to this is CPPP which will revert to PPP if CPPP is not
available on the client.

• slip—Access server will negotiate a SLIP connection.

• cslip—Access server will negotiate a Compressed-SLIP connection.

• dialout—Access server will give a dialout connection. The dialout connection is an AT command set driven

connection into one of the access server modems. On line help is provided by typing at help <cr>.

• vpn—This option is currently not supported.

Note If a user attempts to login in using a different service than the one he

or she has been provided, the access server will reject the user. The
exception to this is CPPP which will revert to PPP if CPPP is not
available on the client.

Note All changes made to the running configuration must be saved to

FLASH by selecting Record Current Configuration under

ate Actions on the HOME page of the access server. Failure to do so

Immedi-

will cause all configuration information to be lost the next time the
access server is re-booted.

After the user information has been entered, click Submit.

Modify Static User

To modify or further configure the user, click the username you just created to display the Static User window
(see figure 16). Refer to the following sections while modifying the Static User settings. When you are finished,
click Submit to store the changes.

Figure 16. Static User settings window

61 Modify Static User

Model LRA2900A RAS Administrators’ Reference Guide 5 • Authentication

Service IP (suServiceIP)

This is the IP of the RLogin or Telnet host, or the static IP address assigned to the user. This is determined by
the option selected in

Service

(see “Service (suService)” on page 60).

Service Port (suServicePort)

This is the port number to connect to the service host. If the number is 0, the access server will use the default
values for Telnet (port number 23) and RLogin (port number 513).

Note After you have submitted all changes, click on the HOME link in the

Configuration Menu. Once there, click on the Record Current

Configuration button (located under

Immediate Actions) to save the

changes to FLASH memory on the access server.

All changes made to the running configuration must be saved to
FLASH memory. Failure to do so will cause all configuration infor­mation to be lost the next time the access server is re-booted.

Filter ID (suFilterId)

This is the ID of the filter assigned to the static user. A filter controls packets that can be sent or received by the
dial-in user to which it is applied. Only one filter can be assigned to a user defined in the static user authentica­tion database.

Note Explicitly assigning a filter to a static user will keep default dial-in

filters from being applied.

6 • DAX Model LRA2900A RAS Administrators’ Reference Guide

Introduction

The digital cross-connect (DAX) link allows configuration of the access servers’ digital cross-connect that man­ages the time slots and clocking between the WAN ports.

The access server uses a single clock source for all WAN ports. Therefore, to avoid data loss caused by variations
in network timing, each access server should terminate WAN connections from a single timing provider. WAN
connections from multiple timing providers can be terminated in the access server if all the providers source
their timing from the same stratum clock or if the access server provides the network clock.

Click on

DAX under the Configuration Menu to display the DAX main window (see figure 17).

Figure 17. DAX main window

Configuring the DAX

There are three variables to select when configuring the DAX circuit:

• Circuit Type—Defines the overall clocking scheme for the entire access server (refer to “Circuit Type (dax-

ClockMode)”

• Main Reference—Determines which WAN link supplies the clock for the system (refer to “Main Reference

(daxClockMainRef)” on page 66)

• Fallback Reference—Enables the configuration of a back-up clock reference should the Main Reference fail

(refer to “Fallback Reference (daxClockFallbackRef)” on page 66)

Circuit Type (daxClockMode)

Defines the overall clocking scheme for the entire access server. For each circuit a selection must be made as to
the overall clocking scheme of the entire system. If your system has only one circuit displayed, then that circuit
must be set to Master.

The following settings are available:

• master(1)—The master device is responsible for providing the master system clock in synchronization with

one of its references. If your access server has only one circuit, then this setting must be Master.

• secondary(2)—The secondary circuit provides the master system clock if the master circuit fails.

• slave(3)—Slave devices provide the system clock references for use by the master or secondary.

65 Introduction

Model LRA2900A RAS Administrators’ Reference Guide 6 • DAX

Main Reference (daxClockMainRef)

The main reference parameter determines which WAN link will supply the clock for the system.

The following settings are available:

• none(0)—No clock selection. This would be used in conjunction with either a secondary or slave circuit.

• wan-1(1)—Use WAN Port 1 for primary timing. Generally the first WAN connection will be used as the

main reference.

• wan-2(2)—Use WAN Port 2 for primary timing. Generally the second WAN connection will be used as the

fallback reference (see “Fallback Reference (daxClockFallbackRef )”).

• wan-3(3)—Use WAN Port 3 for primary timing.

• wan-4(4)—Use WAN Port 4 for primary timing.

• wan-5(5)—Use WAN Port 5 for primary timing.

• wan-6(6)—Use WAN Port 6 for primary timing.

• wan-7(7)—Use WAN Port 7 for primary timing.

• wan-8(8)—Use WAN Port 8 for primary timing.

• netref-1(101)—Use to obtain system timing from a slave circuit.

• netref-2(102)—Use to obtain system timing from a slave circuit.

• internal(200)—Use internal free-run oscillator for the system clock.

• external(300)—Not currently implemented.

Fallback Reference (daxClockFallbackRef)

The fallback reference enables the configuration of a back-up clock reference should the main reference fail.

The following settings are available:

• none(0)—No clock selection. This would be used in conjunction with either a secondary or slave circuit.

• wan-1(1)—Use WAN Port 1 for secondary timing. Generally the first WAN connection will be used as the

main reference.

• wan-2(2)—Use WAN Port 2 for secondary timing. Generally the second WAN connection will be used as

the fallback reference. If there is only one WAN connection, then the fallback reference should be set to
oscillator.

• wan-3(3)—Use WAN Port 3 for secondary timing.

• wan-4(4)—Use WAN Port 4 for secondary timing.

• wan-5(5)—Use WAN Port 5 for secondary timing.

• wan-6(6)—Use WAN Port 6 for secondary timing.

• wan-7(7)—Use WAN Port 7 for secondary timing.

• wan-8(8)—Use WAN Port 8 for secondary timing.

• netref-1(101)—Use to obtain system timing from a slave circuit.

Configuring the DAX 66

6 • DAX Model LRA2900A RAS Administrators’ Reference Guide

• netref-2(102)—Use to obtain system timing from a slave circuit.

• internal(200)—Use internal free-run oscillator for the system clock

• external(300)—Not currently implemented.

Clock Status (daxClockFailure)

The clock status indicates alarm conditions relating to the system clock. If there are no alarms, the DAX page
will indicate No Alarms (see figure 17 on page 65). Should one or more alarms be present, an Alarms Present
message will be displayed with the following list of potential clock failures (figure 18).

• Main Reference Fail(1)—The main clock reference has failed

• Fallback Reference Fail(2)—The fall back clock reference has failed

• Master System Fail(4)—The Master System clock has failed

• Secondary System Fail(8)—The Secondary System clock has failed.

7 • Dial In Model LRA2900A RAS Administrators’ Reference Guide

ML ID (diactMultiIndex)

Subsequent calls in a multilink PPP/ISDN call have a pointer to the bundlehead or originating call.

User (diactusername)

The user name that the caller entered. This can be a static user or a radius user’s login name.

State (diactState)

As the call comes into the access server it can be in one of five states.

• Ringing—The call has been recognized by the access server and is in process of going off hook.

• Connecting—The unit has assigned a DSP to the incoming call and is now in the process of negotiation of

the type of modulation—V.34, V.32, ISDN, or 56K.

• Authenticating—The access server is in the process of verifying the users passwords by using static or

RADIUS authentication.

• Online—The access server has completed authentication and we are ready to access the Internet.

• Dead—The user has been disconnected and this message will go away after the linger time has expired.

• Bury—Kill the call and remove it from the dial-in main window.

Duration (diactSessionTime)

The number of seconds this call was/is active. Time in seconds the user has been connected.

Modify Login

This portion of the Dial In Modify window (see figure 24 on page 85) describes configuring the IP address
pool, login technique and general login information.

IP Address Pool (diIpPool)

The IP address pool contains the IP addresses that are assigned dynamically to the dial-in connections. Type the
IP address pool in the space provided. The IP addresses can be non-contiguous addresses configured as follows:

– Blocks of IP addresses are designated with a dash (-) separating the first and last host in the block (for

example, 192.49.110.151-155)

– The addresses can be from a subnet other than the local network the RAS is on

– The IP address pool can have IP addresses from multiple subnets. The subnets must be separated by a

semi-colon (for example, 192.155.155.1-6; 192.155.160.41-46)

Note The IP address pool is limited to 39 characters.

Login Technique (diLoginTechnique)

This variable defines the login sequence that a dial-up user will see. The various options are defined below:

• none(0)—no login sequence is enabled

• textORpap(1)—This setting enables clear text logins or PPP calls using PAP authentication.

• text(2)—A username prompt is displayed and a username must be entered. If the received username is a

static user with no password defined, then the connection completes and no password prompt is issued. If a
password is required then a password prompt is displayed and a password must be entered.

Note Text login with ISDN is not currently implemented.

• pap(3)—This setting assumes that all calls will be PPP users. No username or password prompt will be dis-

played. The system will go directly to PPP processing. The dial-up user must be configured for PAP authen­tication.

Note If the user trying to connect to the access server is not configured for

PAP he will be disconnected.

• chap(4)—This setting assumes that all calls will be PPP users. No username or password prompt will be dis-

played. The system will go directly to PPP processing. The dial-up user must be configured on his computer
for CHAP authentication.

Note If the user trying to connect to the access server is not configured for

CHAP he will be disconnected.

• chapORpap(5)—This setting assumes that all calls will be PPP users. No username or password prompt will

be displayed. The system will go directly to PPP processing. The dial-up user must be configured for PAP or
CHAP authentication. The access server will always request CHAP authentication first. Therefore, if a user
can negotiate either CHAP or PAP, CHAP authentication will be performed.

Dial In Modify window 86

7 • Dial In Model LRA2900A RAS Administrators’ Reference Guide

• textORchapORpap(6)—This setting enables clear text logins or PPP calls using PAP or CHAP

authentication.

Username Prompt (diUsernamePrompt)

This is what will be displayed when the user first connects after the Initial Banner is displayed. The string can
be up to 39 characters. This should be a ASCII printable string and can include carriage returns and line feeds.
This applies only for text users not PPP. (See also Initial Banner.) For example the prompt could be:

Enter your username:

Password Prompt (diPasswordPrompt)

This defines the character string that will be displayed at user authentication time to request the users pass­word. The string can be up to 39 characters. This should be a ASCII printable string and can include carriage
returns and line feeds. This applies only for text users not PPP. For example, the prompt could be:

Enter your password:

Initial Banner (diBanner)

This is usually a message welcoming the user. The message can be up to 39 characters and should be an ASCII
printable string. It can include carriage returns and line feeds. The username prompt immediately follows the
initial banner. This banner only appears for text login users.

Modify Service

This portion of the Dial In Modify window (see figure 24 on page 85) describes changing user login services.

Default Service (diService)

This object defines the default service that will be provided if the authentication technique does not specifically
name a service type, and if no service is specified in the static user’s profile under Authentication. For informa­tion about the static users database, see Chapter 5, “Authentication”.

The options are:

• rlogin(1)—User will be automatically given a rlogin prompt.

• telnet(2)—User will be automatically given a telnet prompt.

• tcpraw(3)—All 8 bits are passed unchecked and unaltered.

• ppp(4)—Only a PPP connection will be allowed.

• slip(5)—SLIP or PPP connection will be allowed.

• vpn(6)—Not currently implemented.

Default IP Service (diServiceIP)

This object defines the IP address that will be used for login connections (telnet or rlogin) when the authenti­cation technique has not provided an IP address to connect to.

87 Dial In Modify window

Model LRA2900A RAS Administrators’ Reference Guide 7 • Dial In

Default Service Port (diServicePort)

This object defines the IP port number that will be used for login connections (telnet or rlogin) when the
authentication technique has not provided a port number to connect to. If no TCP port number is provided
then the following UNIX defaults will be used:

• telnet port 23

• rlogin port 513

Force Next Hop (diForceNextHop)

All packets received on the specified dial-up link will be forwarded to the specified gateway. The gateway must
be on the same network at the remote access server. This is the default setting that will be used if the setting is
not overridden by the RADIUS response for that particular user. A setting of 0.0.0.0 indicates that this option
is not in effect.

The RADIUS attribute used to set the Force Next Hop is attribute 209, a Black Box vendor extension. For a
full list of RADIUS attributes, see Appendix A, “Supported RADIUS Attributes”.

Modify Domain Name Server

This portion of the Dial In Modify window (see figure 24 on page 85) describes modifying the primary and
secondary domain name servers for IP and Microsoft Windows.

Link Compression (diLinkCompression)

This object enables the PPP link layer address and protocol field compression. The following options are available:

• enable(1)—PPP negotiations will perform link compression unless the other end of the link is unable to

work with compression

• disable(2)—No compression will be used on the PPP link. This is the default setting

Default Max Receive Unit (diConfigInitialMRU)

This is the default setting for Maximum Receive Unit (MRU). This value can be changed by authentication or PPP.

Allow Magic Number Negotiation (diConfigMagicNumber)

Determines if magic number negotiation should be done. This access server parameter is used to check whether
a link is in a looped-back state. The following options are available:

• enable(1)—The local node will attempt to perform Magic Number negotiation with the remote node.

• disable(2)—Magic Number negotiation will not be performed.

In any event, the local node will comply with any magic number negotiations attempted by the remote node,
per the PPP specification. Changes to this object take effect when the link is restarted.

For more information, see Section 7.6, "Magic Number," of RFC1331.

Frame Check Sequence Size (diConfigFcsSize)

The size (in bits) of the frame check sequence (FCS) that the local node will generate when sending packets to
the remote node. This setting becomes active when the link is in the up—able to pass packets—operational
state (for more information, refer to “Operational Status (diIpOperStatus)” on page 105).

Compression (diIpConfigCompression)

Determines whether the local node will attempt to negotiate IP compression. The following options are available:

• none(1)—The local node will not attempt to negotiate IP compression

• vj-tcp(2)—The local node will attempt to negotiate compression mode indicated by the enumerated value

Changes to this object take effect when the link is restarted.

For more information, see Section 4.0, "Van Jacobson TCP/IP Header Compression" of RFC1332.

MultiLink (diConfigMultilink)

MultiLink enables a user to connect using multiple channels. This enables dial-up users whose equipment sup­ports MultiLink PPP or multi-channel ISDN to use multiple channels to get higher data transfer rates.

Set the MultiLink - Max # of Calls per User parameter to the maximum number of channels a user can take for
a single connection. Setting the parameter to 0 disables the MultiLink option.

MultiBox (diConfigMMP)

MultiBox enables a user to have multiple connections even if the subsequent call for an additional channel is on
a different access server from the originating channel (bundlehead). MultiBox is useful when a single number
called by a user accesses multiple T1/E1s and subsequently different access servers.

Dial In Modify window 90

7 • Dial In Model LRA2900A RAS Administrators’ Reference Guide

Setting the MultiBox - Query timeout parameter to enable(1) activates the MultiBox option. Setting the param­eter to disable(0) disables the MultiBox option. If MultiBox is disabled, then acquiring an additional channel
will fail if the bundlehead is not on the same access server.

Modify Maximum Time

This portion of the Dial In Modify window (see figure 25 on page 89) describes modifying the time-out values
for the session idle time, time to login, and the MIB data linger time.

Maximum Session Time (min) (diSessionTimeout)

This is the maximum time (in minutes) that a connection is allowed to be maintained. After this time the con­nection will be terminated, even if there is active traffic on the connection. This is a default setting, and it can
be overridden by the authentication settings of a specific user. Setting the parameter to 0 means the connection
will never be terminated.

Maximum Idle Time (min) (diIdleTimeout)

This is the maximum time (in minutes) that a connection is allowed to be idle with no traffic. After this time,
the connection will be terminated. This is a default setting, and it can be overridden by the authentication set­tings of a specific user.

Time to login (sec) (diLoginTimeout)

This is the maximum time (in seconds) that a user is given to log in. This only applies to the time before the
user is authenticated. This setting should take into account any time delays incurred when querying a remote
authentication server (such as a RADIUS).

Call History Timeout (min) (diLingerTime)

Number of minutes a MIB entry will remain in the Active table after the call it pertains to is disconnected. Up
to 15 dead calls can be displayed. Setting the parameter to 0 disables the timeout feature.

tiating the type of modulation (V.34, V.32, ISDN, or 56K).

• LcpNegotiate—The link is negotiating LCP parameters.

• Authenticating—The access server is in the process of verifying the user’s password by using static or

RADIUS authentication.

• Online—The access server has completed authentication and the user is now able to access the Internet.

• 12tpTunneled—Subsequent multilink call that was answered by another access server and tunneled to the

access server that has the originating call.

• Kill—The administrator can manually disconnect the user by activating this parameter.

• Dead—The user’s call has been disconnected. This message disappears when the linger time expires.

• Bury—The call has been killed and removed from the dial-in main window.

Username (diactUsername)

The caller’s username.

Password (diactPassword)

The caller’s password.

Shared Unique ID (diactMultiIndex)

Used for multi-link PPP, this is the unique identification shared between multi-link active calls.

• Rlogin —The user has an rlogin session running

Security Level (diactAccessLevel)

This is the security level assigned to the selected call. Passthru is the default security level. Monitor and Change
security levels are used by the access server administrator.

• Passthru(1)—Allows no access to the configuration screens.

• Monitor(2)—Allows read-only access to the configuration screens.

• Admin(4)—Allows full read and write access to the configuration screens.

• None(0)—Validation failed.

DSP Link (diactDSPIndex)

The physical DSP chip that the user’s call is on. This is a number from 0 to 59.

Interface Link (diactIFIndex)

Virtual interface in the PPP multiplexer inside the access server that accepts packets from the Ethernet port for
the connected dial-in user.

WAN Link (diactLinkIndex)

The T1/E1 WAN port number that the call is on.

Time Slot (diactSlotIndex)

Shows which T1/E1 channel the call is on. This is a number from 1-30.

IP Address (diactIP)

The currently assigned IP address from the IP address pool or the RADIUS server. The remote users’ PC is
assigned to this address. The address appears in the IP address (0.0.0.0) format.

Port # on Remote Machine (diactPort)

The TCP port number being used by this connection. The range is from 0 to 65,535. Ports in the range of 0 to
1023 are well-known ports used to access standard services. Telnet uses port 23 and rlogin uses port 513.

Session

This portion of the Dial In User Statistics window (see figure 27 on page 95) shows session information for a
unique user ID.

Start time of call (diactSessionStartTime)

The amount of time the access server had been up when the call was initiated.

Time Call Is/Was Active (diactSessionTime)

The amount of time the call was/is active.

Minutes Until Timeout (diactRemainingIdle)

Number of minutes remaining until idle timeout.

Model LRA2900A RAS Administrators’ Reference Guide 7 • Dial In

Time Left In Session (diactRemainingSession)

Number of seconds remaining in this session. This value is only displayed if session timeout has been activated.

Termination Reason (diactTerminateReason)

The reason a call was disconnected.

• stillActive(0)—Call is currently connected

• idleTimeout(2)—Call exceeded idle timeout parameter

• killed(3)—Call terminated by administrator

• userHangup (5)—DSP discovered remote modem was hung up abruptly. Examples could be that the phone

line was pulled out of the wall jack or the user terminated the communications without closing the connec­tion down. If the modems are unable to bring up the physical line by successfully negotiating the modula­tion, userHangup will be registered if the remote modem gave up trying to complete the call.

• modemCanNotConnect(6)—The modems are not able to bring up the physical line by successfully negoti-

ating the modulation. The remote access server has given up trying further to complete the physical connec­tion.

• pppClose(8)—This termination reason will be given after PPP is initiated and the connection is discon-

nected. An example would be if LCP negotiations failed. Another cause could be if the bundlehead in a
multilink call is terminated before the tunneled call is termination.

• lcpClose(9)—Close initiated by LCP. normal shutdown of call

• loginTimeOut(10)—Exceeded login timeout parameter

• userTerminated(11)—A problem is discovered initiating the dial-in users telnet, rlogin or tcpclear session.

• maxNumCalls(21)—Exceeds maximum number of channels that can be allocated to the same call.

• notPapReq(24)—The access server is waiting for a PAP request packet containing the username/password

for a call but the packet received was not a PAP request packet.

• noIpPoolAddr(30)—Authentication server did not assign an IP address and access had no IP address pool

defined to assign an IP address

• noIpAddr(31)—Authenticator did not return an IP address for the service (e.g. telnet or rlogin) and the

default service defined does not specify the service IP address

• maxLoginAttempts(32)—Exceeded maximum login attempts as defined under the Dial-in link.

• invalidDefaults(44)—Default service is set to a value other than rlogin, telnet, tcpraw, ppp, slip or vpn

when using a login technique of None. No IP address is defined when using rlogin or telnet. Invalid telnet
or rlogin services ports have been defined in the default service.

• noDspAvailable(45)—When the remote access server attempted to connect the incoming call to an avail-

able DSP, no DSP could be found. Some examples why a DSP could not be found are:

– DSPs are no longer available to the resource pool because they are in reboot or hardware failure states.

– DSPs are in an unavailable administrative state although they are functional.

– The DSP resource pool is split between link A and link B and a call has been routed to a link over and

above the number of DSPs allocated to that link.

• papAuthenticationFailure(49)—Invalid username/password combination

• papInvalidPacket(50)—Non-printable characters in username or password received from remote end during

authentication

• authenServerTimeout(51)—Authentication request timed out. The RADIUS server did not send a response

to the authentication request before the timer expired.

• authenAccountingTimeout(52)—Accounting request timed out. The RADIUS server did not send a

response to the accounting request before the timer expired.

• unknownProtocol(53)—The user initiates a PPP connection but the RADIUS replies to the remote access

server that the user is not allowed to connect using PPP.

• mfr2DisWaitCalled(54)—Call disconnected while we were waiting for the next expected called number

digit. The number of called number digits expected is more than the digits actually being sent or the Last
response code is configured incorrectly so the remote access server and switch can not continue on with the
interregister signalling.

• mfr2DisAckCalled(55)—Call disconnected while we were in the process of sending back the ack tone for a

called number digit or while we were waiting for the termination of the far end tone in response to our ack.

for the last expected called digit or while we were waiting for the termination of the far end tone in response
to our ack.

• mfr2DisWaitCalling(57)—Call disconnected while we were waiting for the next expected calling number

digit. The number of calling number digits expected is more than the digits actually being sent or the Last
response code is configured incorrectly so the remote access server and switch can not continue on with the

• mfr2DisAckCalling(58)—Call disconnected while we were in the process of sending back the ack tone for a

calling number digit or while we were waiting for the termination of the far end tone in response to our ack.

• mfr2DisAckLastCalling(59)—Call disconnected while we were in the process of sending back the ack tone

for the last expected calling digit or while we were waiting for the termination of the far end tone in
response to our ack.

ber of calling digits expected may be less than the number of digits sent or the last response code for the call­ing number is incorrect.

• exceedsMultiLinkLimit(64)—Exceeds multilink channel limit set either on the remote access server or in

the user entry on the RADIUS server
