1 Introduction

1.1 The Router Module

The Router module is a component of the Series 8000 range of X.25 switches.

It provides an IP Routing function which allows transparent routing of IP frames between the local Ethernet network and remote IP Ethernet networks via a Series 8000 network. The IP Routing function can support the routing of all the upper layers of the TCP/IP protocol suite.

The module also provides a gateway function allowing interconnection between Series 8000 and TCP/IP Ethernet networks.

Physically it comprises a plug-in card which fits into a Series 8000 PSE taking up a single slot. Connection to the Ethernet 10 Mbps LAN is through a direct ''tap'' into the LAN cable.

X870-300351 Issue 1 1-1 Rev.0

Page 10

1.2 IP Routing

IP Routing deals with Internet Protocol (IP) packets, which are the most common type of LAN network layer packets. IP is part of the TCP/IP protocol suite. IP Routing in Router allows IP packets to be transparently passed across the X.25 network to remote Ethernet LAN networks, using Series 8000 X.25 PSEs to provide the transport medium.

Because the IP packets are routed transparently, any protocol supported by IP may be transported across the X.25 network.

Router will perform three basis tasks in order to successfully route IP packets through a given network. Firstly, routing tables will be maintained and distributed throughout the network, thus allowing all participating routers to keep track of changes in network topology (refer to Appendix C for an explanation of the Routing Information Protocol). Secondly, those tables will be used by Router to take routing decisions when receiving IP packets whose destination network address does not correspond to the directly-connected network. Router will then forward these packets to another router closer to the destination. Thirdly, X.25 calls will be set up and cleared down as required in order to allow IP packets (including routing information) to be passed to other Routers across the Wide Area Network, encapsulated in X.25 packets.

Automatic distribution of routing information by each Router can be achieved by broadcasting such information onto the directly-connected LAN network, and by sending the information to each of the participating Routers across the X.25 network.

When a Router is first installed in a network, it has no knowledge of the existence of the remote Routers in the X.25 network, so the X.121 addresses of these remote Routers will need to be configured manually.

The X.121 addresses will subsequently be used in X.25 call set-ups to the remote Routers.

Instructions on how to configure a Router to participate in IP Routing can be found in Section 4.7.

Figure 1-2 shows a typical application of IP Routing allowing data to be passed between remote IP Ethernet LANs.

In order to route IP packets originating on Ethernet network 1.0.0.0 to a destination on Ethernet network 4.0.0.0, Router 1 will on receipt of a packet from the LAN addressed to network 4.0.0.0 examine its routing tables. This should yield the information that Router 2 is the ''next hop'' router.

If an X.25 connection already exists to Router 2, the IP packet will simply be sent down the existing SVC encapsulated in X.25 packet(s); otherwise a

Page 12

new call will be made to the X.121 address of Router 2 before the data can be sent.

On receipt of the IP packet, Router 2 will examine its routing tables, which should allow it to forward the packet to the ''next hop'' router on Ethernet network 2.0.0.0 en route to its final destination.

1.3 The Gateway Function of Router

A user on either X.25 or Ethernet can make a connection to a service on either network via a single call from a terminal; this is commonly known as a 'seamless connection'.

Figure 1-1 shows a typical application of the gateway function of Router, allowing X.25 terminals to access host computers connected to an Ethernet LAN.

Figure 1-2 Typical Application

HOST 1

HOST 2

X.25

ETHERNET LAN

HOST 3

ROUTERROUTER

Router provides facilities to ensure that the boundary between the two networks (X.25 and LAN) is as invisible as possible. This allows the two different networks to appear to the users as one network.

Seamless connections are achieved by automatically translating LAN addresses to X.25 addresses, and vice versa. The translation process takes WAN service numbers (X.121 addresses), and maps them to specific TCP/IP addresses ('sockets', see Appendix C.2). Therefore any standard X.25 service can be converted to a standard LAN service address.

An example would be the use of Router as an additional access to a Host computer. The Router would, upon receipt of an X.25 call, automatically contact the Host over the Ethernet using an IP and TCP address. The users would be unaware of how they were actually connected.

X870-300351 Issue 1 1-5 Rev.0

Page 14

1.4 Multiple Sessions

In some circumstances it would be advantageous to allow an operator at a terminal to change between two or more applications, or services, at the press of a key. For example, a sales desk may require quick access to Sales Order Processing, Stock Control, and Electronic Mail services.

Multiple sessions provide such a capability. Router allows users to make more than one outgoing connection. The user simply switches between the sessions by pressing appropriate keys. The keys are known as 'hot-keys', and are completely manager-definable.

X870-300351 Issue 1 1-6 Rev.0

Page 15

1.5 Services

Router has two basic types of service: WAN Services and LAN Services. Router Services describe the address of the service, an optional password, and connection characteristics (via profiles). Each service has a name which can be employed by users to connect to their required destinations.

•A WAN Service contains an X.121 address. Users can connect to the service by two basic methods. The first allows the user to specify the name of the service; the second is automatic, or seamless selection. This occurs when an incoming LAN call is received with a TCP port that matches the TCP port specified in the service. For example, it is possible to configure a WAN service for access to a DEC system with a TCP port of 100; when an incoming LAN call for TCP port 100 arrives, the TGate automatically calls the configured X.121 address.

•A LAN Service contains a LAN socket address (IP address and TCP port). Again, like the WAN service, this can be selected either by name or automatically by an incoming X.25 call to Router's X.121 address. When a call from an X.25 device arrives, Router automatically calls the destination LAN address.

After a service is created, it must be enabled (a disabled service cannot have a connection made to it). When enabling a service it is first checked for any inconsistencies. If there are any, then the service will not be enabled and the manager is informed of the error.

Both the LAN and WAN have special services to allow users to enter dialogue. If the service is specified without a destination (e.g. LAN service without IP address and TCP port), but has a specified incoming address (i.e. X.121 sub-address for LAN services and TCP port for X.25 services), when an incoming call matches this incoming address, Router will enter a dialogue using the specified (or default) user profile. For example, if a WAN service called LAN-DIALOGUE is configured with a TCP port of 23 but without an X.121 sub-address, then when an incoming LAN call for TCP port 23 arrives, the user will enter a dialogue with Router. The service can also be configured with a password, in which case, the user will be requested to enter the password before entering the dialogue.

X870-300351 Issue 1 1-7 Rev.0

Page 16

1.6 Profiles

Profiles are used within Router to define sets of characteristics that should be applied in given circumstances. There are three types of profile: a User Profile that describes the characteristics to be applied to a user, a Service Profile that describes the characteristics of a connection to a service, and a Terminal Profile that describes the characteristics of a manager's terminal. All profiles can be given a name to aid clarity.

• User Profile defines the hot-key sequences, the maximum number of simultaneous sessions the user can hold, whether or not the user is allowed to login to the manager facilities, and whether all services must be specified by name and not address. Additionally, an inactivity timer can be set so that users will be disconnected from Router if they are inactive for too long. This can help prevent users leaving terminals unattended but still using valuable resources. A User Profile is referenced by a service.

• Service Profile defines the service connection characteristics, including the initial sequence that is sent to the service upon connection (e.g.

service is selected (e.g. entered by hot-key). This refresh sequence requests that the service redisplay the image on the user's screen. An inactivity timer can be set so that the service will be disconnected if it is inactive for too long. This can help prevent users staying logged in to costly services and not using them. A Service Profile is referenced by a service.

• Terminal Profiles are provided to allow different types of terminal to manage Router successfully. There are four pre-defined profiles for the more popular terminals (VT100/ANSI, ADM3A, IBM 3101 and CIFER

2605), and four manager-definable profiles. Each profile describes both the input sequences for recognition of various functions (e.g. Submit Form), and output sequences for screen control. The Terminal Profile can be selected whenever the manager facilities are accessed, or can be specified within the general configuration form.

2 Installation

This chapter is provided as a supplement to the full installation guides for Series 8000, knowledge of and reference to which is assumed throughout.

2.1 Hardware Description

The Router software can be loaded onto one of two hardware variants: the TGate/Router card for use within the 8325 card frame, and the TGate/Router module for use in either the 8425 or 8525 card frame. Whichever variant is in use, TGate/Router provides a single IEEE 802.3 compliant interface. Various physical LAN interfaces are available as LPIMs (LAN Port Interface Modules). The interfaces available are standard AUI, 10Base2 (Cheapernet), and 10BaseT (twisted pair). Each TGate/Router carries a unique 48-bit Ethernet address which is stored in the Ethernet PROM.

The following subsections give a brief description of the two TGate/Router hardware variants.

Page 18

The only indicator is a green LED, serving as a 'heartbeat', blinking at a rate dependent upon processor utilisation.

The TGate/Router card displays real-time status information via the 8325 display/control panel, in line with other 8325 cards (see Chapter 7 of the 8325 Installation Guide).

The front of the TGate/Router card carries three 96-way male DIN connectors to engage with the 8325 backplane.

2.1.2 The 8425/8525 TGate/Router Module

The TGate/Router module for the 8425/8525 systems comprises a threeboard combination of UPM4 (X890-607011), TGate/Router (X890-606712) and Manager PAM (X890-606811). The UPM4 and TGate/Router fit in the front of the chassis, while the PAM fits into the rear, as shown in Figure 2-2.

There are no configuration links or switches on either the UPM4 or the TGate/Router.

The UPM4 has several activity indicator LEDs. A seven-segment LED display is used to display real time status information, along with a heartbeat indicator, in line with other 8425/8525 cards. A single green LED indicates processor activity, and a bar graph display indicates further status information.

The PAM rear panel carries four, centrally-mounted 25-way D-type female connectors, all of which are reserved for future use. At the top is a 15-way female D-type connector providing the AUI port. Below the AUI is a cutout for an optional LPIM providing either a 10Base2 (Cheapernet) or a

2.3 Installation and Removal

A TGate/Router card (or combination of cards) may be inserted in any slot of the card frame, except slot 1 which is reserved for the Node Manager card. TGate/Router cards (or combinations) may be inserted or removed while the node is powered up, provided that the following procedures are carefully followed:

2.3.1 8325 Card

To insert a card into a live system:

1. Use an engineering wrist strap attached to the earthing stud provided on the rear panel of the chassis.

2. Remove the blanking panel, where fitted, from the slot into which the card is to be inserted, by carefully unscrewing the captive screws at either end. Ensure that the screws are fully undone.

3. Slide the card along the card guides until it is approximately 20 mm away from being fully home. Ensure that the card is straight and correctly aligned, and then push it smartly home to minimise bounce at the connector pins.

4. Secure the card with the captive screws at either end.

DO NOT

OVERTIGHTEN

5. Allow the card to execute its power-up diagnostics and load its operational software from disk before inserting another card. (The node manager software cannot 'hot' load more than one card at a time.)

To remove a card from a live system:

1. Use an engineering wrist strap attached to the earthing stud provided on the rear panel of the chassis.

2. Unscrew the captive screws at either end of the card. Ensure that they are fully undone.

3. Reset the card using the display/control panel (see 8325 Installation Guide Chapter 7).

4. Using a small flat screwdriver or similar tool, gently release the card from the motherboard connectors by levering at the raised corners at each end of the card to be removed. Withdraw the card cleanly.

5. If it is not intended to replace the card, fit a blanking panel in its place (see Statutory Notices on page 0-2).

X870-300351 Issue 1 2-5 Rev.0

Page 22

2.3.2 8425/8525 Module

The following subsections outline the procedure for inserting and removing modules from 8425/8525 systems.

2.3.2.1 UPM4 and TGate/Router (Main Modules)

The main modules are accessed by either opening the front door (8425) or by unscrewing the five captive screws on the front door in the centre section of the unit (8525).

Modules may be added and removed whilst the system is powered up, provided that the following procedures are carefully followed.

The recommended way to plug modules into a live system is as follows:

1. Separate the TGate/Router from the UPM4.

2. Slide the TGate/Router between the upper runners until the connectors are aligned, then push firmly home to minimise bounce at the connector pins.

3. Slide the UPM4 between the lower runners and push home similarly.

4. Allow each pair of modules (TGate/Router + UPM4) to fully load (i.e. display

r) before inserting the next pair.

To remove the combination:

1. Reset the UPM4 module or the pair by shorting the

RST link (marked on

the board).

2. Carefully slide out the UPM4 taking great care to separate the connections cleanly.

3. Carefully slide out the TGate/Router similarly.

2.3.2.2 Port Access Modules (PAMs)

The PAMs are accessed by unscrewing the RFI screening bars on the rear of the unit. Each PAM can then be withdrawn by unscrewing the two knurled screws at either end and withdrawing the PAM from the unit.

Note: The RFI bars form part of the RFI seal: always replace and retighten the screws.

2.4 LPIM Installation and Removal

Live insertion of LPIM modules is not possible. Prior to installation, the TGate/Router card (8325) or PAM (8425/8525) must be removed (see Section 2.3).

2.4.1 LPIM Installation

Before installing the LPIM the port must be selected by moving the links to the positions shown in black in the relevant section of Figure 2-4.

The TGate/Router AUI port provides 15 VDC (8325) or 12 VDC (84/8525), current limited to 500 mA, on circuit VP.

The AUI port does not provide the normal slide locking for securing the cable; instead screw pillars are used. The pillars must not be removed as they also secure the rear panel.

The following AUI drop cables are recommended:

A001-000005 4 metre drop cable A001-000006 20 metre drop cable

2.5.2 Cheapernet Port

The CPIM provides a single 50 ohm coaxial connector for connection to a thin Ethernet/Cheapernet system. The TGate/Router is connected to the network via a coaxial T-piece fitted to the CPIM. If the TGate is located centrally within the network, two 50 ohm coaxial cables (e.g. M151400211, 1 metre) should be used. However, if the TGate/Router is sited at the end of the network, a 50 ohm terminator must be fitted to the unused side of the T-piece. To conform to EMC approvals, both supplied ferrites must be clipped onto the cables, one at either side of the T-piece, as close as physically possible: see Figures 2-5 and 2-6.

2.5.3 Twisted Pair Port

The TPIM provides a 10BaseT interface for TGate/Router. The interface is provided on a 10-way RJ45. The pin-out is described in Appendix A.5.

The two possible cabling schemes available for 10BaseT are:

Station to Station. A crossover cable is required. Station to Repeater. A straight-through cable is required.

3 Initial Configuration

This chapter summarises the tasks that need to be carried out when initially configuring Router. Tasks that are not fully described here, are described in Chapter 4. An example configuration is given in Appendix E.

3.1 Control Panel Displays

On the 8325 control panel, the TGate/Router has a board ID of T and only uses the first character in its 'Display Status' field. The character displayed here corresponds to the operational state of the card. On the 8425 and 8525, the characters are displayed on the TGate/Router card's LED. Under normal running conditions an

r is displayed. However,

various other characters or sequences of characters may be displayed as summarised below.

3.2 Installing the Application

Using the Series 8000 Node Manager, select the Utilities menu and then the Install Application menu.

When you first enter the screen it lists all the applications. An asterisk (*) in the In Use column indicates that an application has been selected for loading onto one or more slots.

The Install command allows you to install a new application onto the PSE from the Router distribution disk. When you select this command, you will be prompted to insert the distribution disk into drive B and press

RETURN.

You then install the application by selecting

PF1. The application is

installed, and the list of installed applications is updated on the screen. The Node Manager copies all the files needed to support the application,

from the Router distribution disk to the system disk. The files copied will be the application's load and database files.

An application may also be installed remotely (if the Series 8000 Node Manager software is version 8 or above). To do this the distribution disk should first be inserted into drive B at the local node and using the Series 8000 Node Manager all files from the disk should be copied from the local drive B to disk drive B at the remote node. It will then be necessary to logon as Node Manager at the remote node and install the application as detailed above. (Full instructions on how to perform a remote file copy are given in the 8500/8400/8325 User Guides.)

X870-300351 Issue 1 3-2 Rev.0

Page 29

3.3 Creating the Router Port

Next, a logical port (with a number 7000-7999 inclusive) must be created for Router to use (for example this could be 7050 to indicate that Router is running in slot 5). Configure the X.25 network level and user facilities as required, and bring the port online.

X870-300351 Issue 1 3-3 Rev.0

Page 30

3.4 Initial Configuration Commands

After cold start, Router is placed in an initial state ready for configuring, with the default configuration defined in Appendix B.

Cold start normally only takes place when the card is first installed. However, if at any time it is found necessary to go back to the default configuration, then a cold start can be performed by deleting the configuration files

Tgateconfig<n> and IPrtrconfig<n> from disk B (see

Series 8000 Xpress PSE (V.7) User Guide, Section 5.3.5), where

n is the slot

number in which the Router resides. Then a card reset may be executed; see the Series 8000 installation guide.

From the Manage Application screen of the Series 8000 Node Manager, set up an entry for the Router port, and use this to call the Router manager.

Alternatively, from a Triple-X PAD or the Series 8000 manager 'mini pad', make an X.25 call using sub-address 99, which calls the Router manager direct.

The X.121 address is:

The default X.121 is shown in Appendix B. In both of the above cases a password is requested. Initially, this is simply

carriage return. The Router then requests that a terminal type is specified. If the terminal type you are using is not listed, or is not compatible with one of the types listed, select the

Define option to define your terminal (see

Section 3.5). The actual configuration depends upon the application that Router is being

used for. Detailed below is a suggested order of configuration. Commands shown in bold are the manager commands that gain access to the relevant configuration screens; commands in brackets are their shortened form.

rtr rc In order to utilise the IP Routing function, the addresses

of all other Routers which may be accessed by the Router across the X.25 network will need to be configured.

rtr rt Static Routes and a Default route may be configured.

The above gives a quick guide to configuring Router. It is strongly advised that this manual be fully studied and the configuration planned, before attempting to actually configure Router; thus ensuring that the user's networking needs are fulfilled as effectively as possible.

Page 32

3.5 Manager-Defined Terminal Configuration

When a user logs on after a cold start, Router requests selection of a Terminal Type. Option 5 of the menu allows the terminal characteristics to be defined to match the terminal in use. This is only necessary if you are not using one of the predefined terminal types.

The process used to define the terminal type is carried out in a TTY 'question and answer' mode as follows. The information highlighted in bold shows an example for a VT100 type terminal.

Define Terminal Profile 5 - MgrDefined Input Parameters Enter Cursor Left Sequence : ^[[D Enter Cursor Right Sequence : ^[[C Enter Cursor Up Sequence : ^[[A Enter Cursor Down Sequence : ^[[B Output Parameters Enter Initialise Device sequence : ^[C Enter Clear Screen & Home sequence : ^[[2J^[[1;1H Enter Clear Line Sequence : ^[[2K Enter Cursor Position Type : ASCII Enter Cursor Position Offset : 1 Enter Cursor Position String : ^[[%r;%cH Is the above correct? : (Y,N,Q)

Control characters are symbolised by a preceding carat (^), for example ^[ is equivalent to an ESC character (see Appendix D). Entering two carats (

^^)

represents one actual carat character and not a control sequence.

indicates the row address, and %c the column address. When the complete definition is entered, type

Yes to confirm the

configuration. Router stores these parameters in Terminal Profile 5 with the name

MgrDefined. The manager then uses these characteristics from

the newly-configured Terminal Profile 5. If

Yes is not entered, then the

whole process is repeated. Once Terminal Profile 5 is configured and entered, the

Define option will no

longer be presented, and future logons are given the option of

MgrDefined,

i.e. the name of Terminal Profile 5.

4 Manager Procedures

4.1 Overview

System management is carried out by a supervisor or network manager. The Router software manager facilities (referred to briefly as the 'manager') provide the dialogue between the supervisory/managerial user and Router. It is an intelligent, command-driven, menu/form based system, and provides the ability to configure, monitor, and control Router.

The manager environment provides you with access to all the configuration, control, and status functions with a minimum of input. This is performed by using a system of menus to display choices, and forms to enter configuration data. All commands within the system may be accessed from any menu, and any menu can be reached directly from any other. The manager combines the menus, forms and commands in a context-sensitive way to give a fully-featured control point for Router.

You can control the Router manager by using one of a number of terminal types (e.g. VT100), whose characteristics are already pre-configured in Router.

An example application and its configuration is given in Appendix E.

X870-300351 Issue 1 4-1 Rev.0

Page 34

4.2 How the Manager Works

4.2.1 Input

Input to the manager is simple. You enter the command or information as an ASCII string, then terminate and submit it for evaluation by entering carriage return or line feed.

The editing functions available are:

Deleting a Character

When a delete (

DEL) or backspace (BS) character is entered, the character to

the left of the current cursor position is removed and all characters to the right of the deleted character are moved left one position.

Cancelling a Line

When a control-U (

^U) or a control-X (^X) character is entered, the entire

input line is cancelled.

Left-Right Cursor Keys

When a cursor key is entered, the current cursor position is moved in that direction. If, however, the cursor is at the left-most or right-most position within the text on the current line, then no action is taken. If a character is entered, it is inserted at the cursor position, and if there are characters to the right of the cursor, those characters are moved right one position.

Repeating a Line

When

^R is entered, the previously submitted command line is recalled and

replaces the current line, ready for re-submission or editing.

4.2.2 General Rules

Each input line can contain more than one command, with commands being separated by a semicolon (;).

All commands are accepted in any mix of upper and lower case and can be terminated by a space, comma, or semicolon.

If the Router finds an error within an input line, any further commands on that line are abandoned and the user is informed of the failure.

X870-300351 Issue 1 4-2 Rev.0

Page 35

When a command is processed, any additional information required is prompted for, and if the prompt has an associated menu then the new menu will be displayed with the prompt.

Menus are only changed when it is necessary to assist and prompt the user in the selection of commands, actions, or items. The user can specify and carry out a complete command without affecting the currently-selected menu.

4.2.3 Using Menus

Menus are available as a general prompting aid. The information displayed in a menu can be either static or dynamic. Dynamic information refers to information calculated or derived at the time of display (e.g. status), and may be automatically updated.

Within each menu there are special functions that can be accessed by entering their associated key sequences. Their functions are:

Help (

^W) – Provides a simple guide to the current menu

and the selections it contains.

Main Menu (

^G) – Causes the Main Menu to be displayed.

Prev Menu (

^L) – Causes the previous menu to be displayed.

(This is chronological and not necessarily hierarchical.)

NextPage (

^N or ^F) – If the current menu has more than one page,

then this sequence causes the next page to be displayed.

PrevPage (

^B) – If the current menu has more than one page,

then this sequence causes the previous page to be displayed.

Both NextPage and PrevPage are cyclic, e.g. if there are two pages and page 2 is currently displayed, when NextPage is entered, page 1 is displayed.

4.2.4 Using Forms

Generally the configuration is entered via forms. Forms are an easy way of presenting and entering information.

X870-300351 Issue 1 4-3 Rev.0

Page 36

Router uses standard form handling throughout. There are several types of field found in a form: Constrained List, Free Format Text, Free Format Blind Text, and Information Only fields. The Constrained List is a list of valid entries for the field, e.g. a directory banner field may only contain ENABLE or DISABLE. It is possible to sequence backward and forward through these lists, or if desired you can enter the value directly. The Free Format Text field is exactly that; you just enter text, e.g. a name. The Free Format Blind Text is similar to a free format field, except that the text is not visible to you (as in a password). The Information Only field presents configuration information that cannot be changed using this form.

When in a form, several special keys sequences may be used. They are: Help (

^W) – Provides a simple guide to this form and the selections

it contains.

CursorUp (

) – Moves geographically upwards one field.

CursorDown (

) – Moves geographically downwards one field.

CursorLeft (

) – Moves geographically left one space, or when at the

left edge of a field or when on a constrained list field, moves left one field.

CursorRight (

) – Moves geographically right one space, or when at the

right edge of a field or when on a constrained list field, moves right one field.

TAB or CR – Moves to the next sequential field (not geographic).

Submit (

^E) – Submits the form for validation and entry into the

system.

Abort (

^C) – Exits the form without validating or updating the

system.

NextPage – If this form has more than one page, this (

^N or ^F) sequence causes the next page to be displayed.

PrevPage (

^B) – If this form has more than one page, this sequence

causes the previous page to be displayed.

Main Menu (

^G) – Causes the Main Menu to be displayed and the form to

be aborted.

Prev Menu (

^L) – Causes the previous menu to be displayed and the

form to be aborted.

X870-300351 Issue 1 4-4 Rev.0

Page 37

Restore (^R) – Restores the field to its current configuration state (or

initial state).

Space – When the cursor is at a Constrained List, the list is

sequenced forward one item.

Backslash (

\) – When the cursor is at a Constrained List, the list is

sequenced backward one item.

<Text> – When in a Free Format Text field, the character is

entered into the field with the standard line editing features.

When in a Constrained List field, the field is cleared and the text entered. The field then behaves like a Free Format Text field.

Clear (

^X or ^U) – Clears the field of any text. (Restores a constrained

list.)

DEL or BS – When in a Free Format Text field, the character to the

left of the cursor is deleted and any characters to the right of this character are moved left one position.

There are a few points to be observed. These are:

• When you attempt to leave a field, the field is validated on its own (i.e. not against other dependent fields). If this validation is unsuccessful, the system will restore the field, bleep at you and place the cursor at the start of the field. (If the field was a Constrained List in free format mode, then it is returned to list mode.)

• When a field is full and you attempt to enter more characters, the characters are ignored, and the system responds with a bleep.

• Control characters, where applicable, may be embedded into a free format field in the standard way, i.e. with a preceding carat (

^). A carat

character is achieved by entering two carats (

^^).

In the following text, form fields are described with the type and size of field specified in brackets, e.g. (Free Format Text, 20) indicates a Free Format text field with a width of 20 characters. Fields indicated as Optional may optionally be completed. In many cases the field defaults to a specified value.

4.2.5 Initial Entry to the Manager

After connecting to Router, you can gain entry to the manager by using the

logon command. Once you are logged on, the manager assumes it is

communicating with a terminal of the type configured as the 'manager terminal type'. If one has not already been configured (e.g. after cold start), you are presented with the following terminal selection menu (in TTY mode):

Terminal Selection Menu

1 - VT100 2 - ADM3A 3 - CIFER2605 3 - IBM3101 5 - Define

Enter selection number:

If you enter 5 (Define), a minimum set of the terminal parameters are prompted for in teletype mode (see Section 2.8).

Router then uses the selected terminal characteristics and displays the Main Menu.

IP Internet Address (Free Format Text, 20) This is a mandatory field. It contains an Internet Address. This address represents the Internet Address of this device; it is used in the generation of IP datagrams and handling ARP packets. See Appendix C.2.

IP Subnet Mask (Free Format Text, 20) This field defines the 'network' or 'subnet' part of the IP address designed for Router. Bit positions in this mask identify which bits in the IP address are significant when determining if an address for a destination device is on the same network or subnet. This can be used to route according to the

Internet address classes (Class A=255.0.0.0; Class B=255.255.0.0; Class C=255.255.255.0 – see Appendix C.2); but more flexibility is provided by this mask, as other ranges may be defined.

IP Fragmentation (Free Format Text, 6) This is a mandatory field, but defaults to 576. It contains a number between 128 and 1500, which specifies the maximum IP datagram size before fragmentation occurs.

IP Time to Live (Free Format Text, 6) This is a mandatory field, but defaults to 32. It contains a number between 2 and 255. It is used to prevent IP datagrams drifting aimlessly through a network. Any datagram that lives longer than this period, or passes through this many IP routers, is discarded.

TCP Window Size (Free Format Text, 6) This is a mandatory field, but defaults to 512. It contains a number between 128 and 4096 in bytes. It is used to determine the number of unacknowledged bytes that can be sent to Router, i.e. the maximum number of bytes in transit across the network between the remote device and Router.

TCP Max Segment Size (Free Format Text, 6) This is a mandatory field, but defaults to 536. It contains a number between 128 and 4120 in bytes. It defines the maximum size of a TCP segment (packet). It is often set to ensure that TCP segments can be sent using single unfragmented IP datagrams.

TCP Initial RTT (Free Format Text, 6) This is a mandatory field, but defaults to 50. It contains a number between 2 and 999 in 10ths of a second. This is the round trip of the TCP link. It is used in assessing whether to re-transmit packets.

Keepalive (Constrained List) This feature allows Router to detect that a LAN user (or host) has disappeared from the LAN network when there is no user activity. Router will poll each LAN session every n seconds to check the host (and session) are still active. If Router gets no response from the session then it will go through the normal re-transmission sequence and then disconnect the session.

Enabled- Perform Keepalive Disabled - Do not perform Keepalive

This form allows you to specify a set of characteristics to be adopted by a user of Router (the user is the originator of a call to Router: this can be a terminal or a host).

Name (Free Format Text, 15) This field is optional. It can contain an alphanumeric name unique to this user profile.

Number (Information) This displays the current profile number.

Escape Seq (Free Format Text, 20) This field is optional. The string must begin with a control character (a carat) and may contain embedded control characters. It is used to define the key sequence required to indicate an escape to dialogue.

Disc. Seq (Free Format Text, 20) This field is optional. The string must begin with a control character (a carat) and may contain embedded control characters. It is used to define the key sequence required to indicate disconnect from service (session).

X870-300351 Issue 1 4-17 Rev.0

Switch Seq1/2/3/4 (Free Format Text, 15) These fields are optional. The strings must begin with a control character (a carat) and may contain embedded control characters to be used to define the key sequence required to indicate that a switch to that session number is required.

Txt (Free Format Text, 11) These fields are optional. They correspond to their adjacent key sequence fields. They are used to describe in a more friendly way, the key sequence the user must use, e.g. PF1 instead of

^[OP.

Directory Banner (Constrained List) This specifies whether a user automatically receives a directory listing after receiving the Welcome banner.

ENABLE – Directory listing is output DISABLE – No directory listing is output

Manager Login (Constrained List) This specifies whether a user using this profile can enter manager dialogue via the login/logon command.

ENABLE – Manager can be entered from dialogue DISABLE – Manager cannot be entered from dialogue

Free Service Selection (Constrained List) This controls whether a user is allowed to specify a service directly, if the service is not in the service tables.

ENABLE – Services may be specified directly (i.e. X.121 address,

Internet Address etc.)

DISABLE – Only services contained in the service tables may be

specified

Session Quota (Free Format Text, 2) This field selects the maximum number of simultaneous sessions that the user can establish when using the profile. It can range from 1 to 4. (This is especially important when a user from the LAN is connecting to X.25 services and consuming valuable channels.)

Inactivity Disc. Time (Free Format Text, 4) This field is optional. It contains a number from 1 to 9999 (minutes).

This value, when present, represents the time period that is allowed to elapse when no activity is taking place in user dialogue (user input or system output) before the user is logged out and all connections are lost.

X870-300351 Issue 1 4-18 Rev.0

Page 51

Parity (Constrained List) This allows you to define the parity of text to be generated when in dialogue.

ODD – Generate odd parity EVEN – Generate even parity MARK – Generate mark parity SPACE– Generate space parity NONE – Transparent from user

Router always ignores incoming parity. Go-Ahead (Constrained List)

This field selects whether a Suppress Go-Ahead TELNET option is sent. It is only used when the user connection is on the LAN.

SUPPRESSED – Enable the use of Suppress Go-Ahead NOT SUPPRESSED – Disable the use of Suppress Go-Ahead

Binary (Constrained List) This field selects whether the Binary TELNET option should be negotiated. It is only used when the user is on the LAN. With Binary mode enabled, the connection is requested to use a full 8-bit data path. With Binary mode disabled, standard TELNET ASCII connection (7-bit data path) is established.

ENABLED – Binary TELNET option negotiated DISABLED – Binary TELNET option not used

CR map (Constrained List) This field selects whether CR (Carriage Return) is to be translated before sending to the LAN. TELNET specifies that a CR character should never be sent on its own, but as part of a sequence: CR-LF (Carriage Return-Line Feed) whenever it is meant as 'new line'; or CR-NUL (Carriage ReturnNull) whenever it is meant as 'back to start of the current line'. This has been implemented differently by different vendors' devices, so Router allows it to be configured here to work with as many devices as possible. This is only used when the user is on the LAN. If Binary mode has been enabled, CR is always sent unchanged.

CR – CR is sent to the LAN unchanged CR-LF – CR is sent to the LAN as CR-LF CR-NUL – CR is sent to the LAN as CR-NUL, and CR-NUL received

from the LAN is sent to X.25 as CR.

If no profile is specified, then the default user profile will be used.

Service prof (Free Format Text, 15) This is an optional field. It contains a service profile number or name. When this service is selected, then the session created will adopt the characteristics of this service profile. If no profile is specified, then the default service profile will be used.

Service Type (Constrained List) This field selects whether the service is specifically for a printer on a WAN connection. The settings are:

NORMAL This is the default selection setting for (multi-user) WAN

services.

PRINTER This setting indicates that the service can only be used by

one LAN user at a time. It is particularly appropriate for connections to printers attached to the WAN. A LAN user requesting this service will not be connected unless the WAN service is ready to accept the incoming call.

HELD PRINTER As PRINTER but when a LAN user disconnects, the WAN

half of the call is kept active (i.e. ''held''). A subsequent LAN user connecting to this service is instantly connected to the WAN connection, saving WAN call set-up time. A held printer service will disconnect after the number of seconds given in Printer timeout if no LAN user reconnects.

Printer timeout (Free Format Test, 4) The number of seconds for which a call to a Held Printer WAN Service type will be held 'open', with no LAN user.

4.9 Item Definitions

The following definitions describe parameters to various commands and are used throughout this manual.

<Flag>

A flag is used to indicate a positive or negative response. A positive response can be indicated in several ways:

TRUE ON ENABLE YES

A negative response is indicated using the inverse of these:

FALSE OFF DISABLE NO

An internet address represents a 32-bit device address within a network, or network of networks. The standard representation is four decimal numbers, with each number representing an individual octet, each number being separated by a dot.

<Number>.<Number>.<Number>.<Number> (e.g. 1.2.3.4)

Each number can be in the range 0 to 255. Note that a number can be entered in hex by preceding the hex number

0x, e.g.

0x01.0x02.0xfd.0xa9 is equivalent to 1.2.253.169

A key definition contains a string part (the key sequence) and a text part (the help text).

<String> <Text> e.g. ''^[OP'' ''PF1''

<Name> (<ServiceName>, <ProfileName>)

A name is an ASCII name from one to fifteen characters. All names must start with an alphabetic character (A-Z). All letters are not casesignificant, but are stored in the correct case for visual clarity.

Names can be used to identify Services (LAN and X.25) and profiles (USER, SERVICE, and TERMINAL). Names must be unique within a given context. This means that the name FRED cannot be used twice in the context of LAN services, but can be used to represent a LAN service, WAN service, user profile, service profile and terminal profile all at the same time. This allows the utmost flexibility. It is however recommended that names be chosen with some meaning, e.g. VT220 for a terminal profile.

A number can be represented as decimal or hexadecimal. A decimal number is entered in standard form, e.g. 100. A hexadecimal number can be entered by preceding the hex number by 0x, e.g. 0xa9 = 169.

A SessionId identifies a session within the context of one user. It can be a session number (1 to 4) or a ServiceName.

<String> (<Text>)

A string is a series of characters. It may contain embedded control characters. Control characters are indicated by preceding the character by a carat, e.g.

^G = Control-G

A carat can be entered by typing two carats (

^^).

When it is required to enter a string in a command line, and not in a form, it is necessary to delimit the string by using double quotes. This allows the string to contain spaces and other item separators, e.g.

''This is an example string^M^J''

(A double quote can be entered into the string by typing two double quotes.)
