Dial Backup The Marlin Network Access

Servers can use ISDN to back up a dedi-

cated link. In the event that the dedicated

link goes down,the Marlin Network

Access Servers activate the ISDN connec-

tion in its place. When the dedicated link

is restored,the Marlin Network Access

Servers terminate the backup connection

and resume use of the dedicated link.

Conﬁguration and Management

Through NauticaRS,Bay Networks Marlin

Network Access Servers provide many

features that simplify conﬁguration and

provide SNMP-based network manage-

ment capabilities. Marlin Network Access

Servers can be conﬁgured and managed

from any local or remote ANSI-standard

terminal or from a PC on the network

using Telnet. SNMP-based management

systems including HP OpenView,Tivoli

NetView for AIX,and Sun Microsystems

Solstice Domain Manager can be used to

manage a Marlin Network Access Server.

Bay Command Console (BCC) This termi-

nal-based (TTY-compatible) tool enables

local or remote platform installation and

maintenance. It is accessed through a

directly attached terminal or PC running

terminal emulation software or a Telnet

session. With support for BCC, NauticaRS

provides command line syntax,which is

consistent with other Bay Networks plat-

forms that support BCC. This is ideal for

situations where the management of the

remote routers is being performed from a

central site.

SeaView Bay Networks SeaView conﬁgu-

rator is a Windows 95 Wizard application

that provides an easy-to-use and consis-

tent graphical user interface (GUI) to set

up or make changes to Marlin Network

Access Servers. Initial conﬁguration of the

Marlin is done using the Bay Networks

SeaView Windows 95 Wizard set up

facility. This allows users to conﬁgure

the router quickly,easily,and accurately.

Security

Bay Networks NauticaRS enables autho-

rized remote users to reach all the

information they need while potential

intruders are prohibited by its multilevel

security features.

Marlin Network Access Servers support

the Remote Authentication Dial-In User

Service (RADIUS),a client/server-based

security protocol. This enables the Marlin

to provide a comprehensive set of security

features and meet varied network require-

ments. Residing on a Windows 95 or

Windows NT platform, and when used

with the Marlin,RADIUS provides

network-wide authentication and autho-

rization to maintain security when remote

access is required. Several levels of com-

prehensive security features are provided

including Calling Line Identiﬁcation (CLI)

feature,which provides veriﬁcation that

incoming ISDN calls have authorization to

connect. For PPP connections, PAP and

CHAP are supported. Additionally, the

Marlin Network Access Servers’RADIUS

implementation will operate with other

third-party RADIUS servers.

6 Data Sheet Marlin Network Access Servers

Marlins also support ISDN Terminal

Adapters. This enables Marlin Network

Access Servers to accept and make calls to

standalone ISDN access routers that use

PPP and PC/notebooks using integral or

standalone ISDN Terminal Adapters sup-

porting PPP or V.120.

Dial-On-Demand Marlin Network Access

Servers take full advantage of the speed

and bandwidth of ISDN lines while main-

taining control of ISDN call costs. Its

industry-leading features for minimizing

line usage help network managers realize

maximum cost savings with ISDN Dial-

on-Demand connections for sites with

intermittent data transfers. The Marlin

Network Access Server brings up a link

automatically when there is data to transfer

and closes down the link once trafﬁc has

stopped for a speciﬁed amount of time.

Bandwidth-on-Demand Marlin Network

Access Servers provide Bandwidth-on-

Demand via Multilink PPP to provide

additional bandwidth across an ISDN link

during peak usage periods. BACP is used

as the mechanism to add or delete links.

Once line usage reaches a predeﬁned level,

the Marlin Network Access Server will

open a second B-channel and load balance

trafﬁc across both channels. When line

usage drops below the predeﬁned level,the

Marlin Network Access Server closes down

one B-channel and returns to the original

bandwidth. For Marlin Network Access

Servers with ISDN interfaces,Bandwidth-

on-Demand can be used to increase the

synchronous port’s bandwidth by using

ISDN channels during peak trafﬁc peri-

ods. Bandwidth-on-Demand can also be

used to add bandwidth to ISDN B-chan-

nels that are already being used.
