Introduction: How To Use the Dictionary of Configuration Parameters

Introduction

Access to the Configuration

Editor

Operator’s Reference

Part I is a dictionary reference of the Parameters found in the Configuration Editor, which is accessable from the Main menu (or by using the [/] [M] hot- key combination in Quick Configuration).

Accessing the Configuration Editor from the Main Menu

Operator’s Reference

Part I is divided into fourteen chapters correspon ding to the options listed in the Configuration menu:

Figure 1-1. The Configuration Menu

Operator’s Reference

To find a parameter description, turn to the chapter corresponding to the Configuration menu option containing that parameter. Then locate the parameter by finding it in its alphabetic order. (You can also locate the parameter description by using the page/parameter listing at the beginning of each chapter.)

Within each chapter, the parameters are listed alphabetically, with descriptions of their functions and a ssociated options. For example, the following sample of dictionary entries describes the Quality of Service and Remote Address parameters, and include:

The parameter names Any applicable options for parameter settings A description of each parameter and each parameter option Any default settings

Disables XON/XOFF software flow control and uses CTS/RTS hardware flow control instead.

Enables XON/XOFF software flow control.

Enables XON/XOFF software flow control and sends out periodic XON signals when the flow of data stops and the router expects to receive more data (checksum failure). For example, the remote connection might have dropped (lost) an XON signal sent by the router and could be waiting for the arrival of the lost signal before transmitting more data. In this case, data transmission resumes when the remote end of the connection receives the next XON signal.

Modem Connection Time

Options

Modem Disconnection Time

Sets the number of seconds to wait for data mode and clear to send and receiver ready signals after asserting request to send and terminal ready signals.

Default: 60

0, 1, 5, 10, 15, 20, 25, 30, 60, 120, 255

Note: The router waits forever for the modem to connect when the parameter setting is 0 (zero).

Sets the wait period, in seconds, for the Cons ole port after the modem disconnects and before the modem reconnects.

Screen Refresh Rate

0.5, 1, 5, 10, 15, 20, 30, 60

Sets the number of milliseconds the receiver ready signal drops before the router disconnects the modem attached to the Console port. This is a form of debouncing the receiver ready signal.

Default: 400

0. 25, 50, 100, 200, 400, 800, 1600, 2550

Note: The modem waits forever when the time period is set to 0 (zero)

Assigns a value to the eighth bit of each ASCII character transmi tted by the router. Match your console’s requirements.

Default: None (no parity)

None, Even, Odd

Note: Most terminals do not operate with an odd or even parity if Bit/Char is set to 8.

Matches the vertical frequency rate (Hz) of the router end of the connection to the vertical frequency rate of the terminal de vice connected to Console port or remote modem.

Default: 3 (Hz)

1, 3, 5, 10, 20, 30, 45, 60

Toggles the Console port connection between standard User mode and Telnet mode.

Default: User

Places the Console port connection in Telnet mode.

Places the Console port in standard User mode.

Specifies the number of bits following each ASCII character received or transmitted by the router. Match your console requirements.

Default: 2

Accepts an ASCII character string identifying the pe rson responsible for the router. For example: John Smith, Building 6.

Accepts an ASCII character string identifying the physi c al location of the router. For example: Technology Center, Engineering Lab.

Accepts a 15 character string (with no spaces) naming the ro uter as a node in the network.

Default: DEFAULT_CONFIG

Optional selection for displaying additional parameters for configuring the Console port connection. Remote users can enable this option to display the session parameters when they want to optimize the connection with the router. For example, the user might want to change the baud rate of the Console port.

Default: 0

Displays no parameters.

Displays these additional parameters:

Baud Rate Bit/Char Connection Inactivity Time Event Filter Flow Control Modem Connection Time Modem Disconnection Time Modem Lost Receive Ready Time Parity Screen Refresh Rate Session Mode Stop Bits Terminal

Note: A smaller set of parameters are displa yed if you later toggle to Telnet Session Mode.

Terminal

VT100

Timezone

Sets the router to match the type of terminal emulation supported by the remote device connected to the Console port.

Default: VT100

ANSI

ANSI terminal emulation.

VT100 terminal emulation.

Sets the local time offset from GMT (Grenwich Mea n Time) for the time protocol, which automatically sets the clock when the router boots.
