NTRODUCTION

The purpose of this addendum is to document the changes introduced between

Release 3 and Release 4 software. This addendum should be read in conjunction

with the Marlin Bridge Reference Manual Issue 3.0 to provide a full description of

the configuration and operation of the Marlin Bridge.

2. R

EFERENCE

The new features that have been added to the bridge Release 4.xx software that

have resulted in management system screen changes are:

• support for the PRI (Primary Rate Interface) ISDN TA

• non propagation of Banyan Vines routing packets to a ‘stub’ network

• static ARP for enhanced security

• restricted SAP learning mode for large Novell IPX networks

• enhanced TA configuration and information screens

• support for the integral U interface North American BRI ISDN TA

The sections listed below have been updated to reflect the changes to the

management screens.

• Port Management

• General Bridging Parameters

• Static ARP Configuration

• IPX SAP Filter Configuration

• ISDN TA Configuration

Information regarding the changes is detailed in the following pages.

If a PRI TA is installed in the unit, it will be automatically detected and the

appropriate number of ports supported by the TA will be displayed in addition to

any other ports on the unit. The number of ports is dependant on the quantity of

channels for which the PRI TA has been keyed, in addition, not all of the keyed

ports may have been activated. See section 2.3 TA C

Figure 2.3 General Bridging Parameters Entry Form

The only difference to the General Bridging Parameters form is that the ‘Learn

Banyan’ parameter has an additional option.

Learn Banyan ENABLE allows the bridge to learn the Banyan Vines

network topology and add router and server information to

the Autocall table. STUB performs the same learning process

as the previous option but in addition inhibits the Banyan

routing updates (RTP) from being forwarded to any

WAN/ISDN port. In this mode of operation the RTP

broadcasts will still be sent out on the LAN port as normal.

Use of the Static ARP option restricts remote access to the management system

from either the LAN or a WAN/ISDN port. If an entry is present in the table, then

responses to ARP requests will only be sent to those devices whose IP address

appears in the table. This feature is disabled if the table is empty and ARP

responses will be sent for all valid ARP requests.

To either ADD or EDIT an entry, enter the IP Address and MAC Address in the

form.

Figure 2.5 SAP Filters Screen

Large Novell IPX networks can contain many servers and services which are

continually advertised via the Service Advertising Protocol (SAP). IPX routing

information is also advertised, via the Routing Information Protocol (RIP). When

any of the ‘Learn Novell’ options are enabled in the CO BR PAR screen, the

received SAPs and RIPs are examined and automatically converted into Autocall

entries. It is therefore possible, in a large Novell network, to fill up the Autocall

table before the required entries have been learned. By specifying a server/service

name in the SAP Filter table, only those SAPs and their associated RIP entries will

be created in the Autocall table.

To either ADD or EDIT an entry, enter the IP Address and MAC Address in the

form.

DDENDUM

Page 7

Name The server or service for which SAP and RIP entries should

be learned. The * wildcard character can be used instead of

one or multiple characters in the name. The wildcard must be

the last character in the name string. In the example above

the entry Server* will learn all SAPs starting with the string

‘Server’ e.g. Server1, ServerB, Server-Accounts.

Figure 2.8 Edit ETSI PRI TA Screen

The ETSI PRI TA is used in networks that support the ETSI CTR4 (NET 5) Euro

PRI signalling standard. The maximum number of channels that can be supported

by this system is 30 Bearer (data carrying) and 1 Delta (signalling) channel.

Using a software key the TA can be programmed to use from 1 to 30 Bearer

channels. A key to provide additional channels, up to the maximum supported by

the TA, can be obtained from your reseller.

ATVER? Displays the ISDN firmware and TA manager interface

version numbers.

ATMODE? This field shows the number of enabled channels, the

operating mode of the TA and the number of keyed channels

are shown. e.g. 6 ETS 30 indicates that 6 channels have been

activated on a ETSI PRI TA which is keyed to support 30

channels.

ATTYPE? The type display shows the generic type e.g. PRI, the line

speed (E1 is a European standard for 2.048Mbps) and the

ISDN firmware loaded.

KEYED

This is the maximum number of ISDN channels this TA can

support.

ACTIVE

CHANS

The number of channels currently enabled can be increased

or decreased by entering a value in this field. This value

cannot exceed the number of keyed channels, an error

message will be displayed if this is attempted.

FRAMING Certain PRI lines cannot support the standard CRC4 type

framing, this option should be set to Non-CRC4 to allow

working on those types of lines.
