a DECbrouter 90 for its routing and bridging tasks. The commands are listed in alphabetical order by command type within sections. The Table of Contents lists the section page numbers; the Index lists each command and the page where its description can be found. See the DECbrouter 90 Products Configuration and Reference, Volume 1, DECbrouter 90 Products Configuration and Reference, Volume 2, and DECbrouter 90 Products Configuration and Reference, Volume 3 for more complete descriptions and examples of the commands. Organization The following chapters are contained in this guide: · Chapter 1, System Use Commands-lists the system use commands. · Chapter 2, System Management Commands-lists the system management commands. · Chapter 3, System Configuration Commands-lists the system configuration commands. · Chapter 4, Interface and Media Configuration-lists the interface and media configuration commands. · Chapter 5, Protocol Configuration-lists the protocol configuration commands. · Chapter 6, ISO CLNS Routing Protocols-lists the ISO CLNS routing protocols. · Chapter 7, Bridging Configuration-lists the bridging configuration commands. · Chapter 8, IBM Connectivity-lists the IBM connectivity commands. v Conventions The following conventions are used in this guide: ------------------------------------------------------------ Convention Meaning ------------------------------------------------------------ system displays Terminal sessions and information the system displays are printed in monospace type. boldface Information you enter is in boldface type. Keywords are also in boldface type. > Nonprinting characters are shown in angle brackets. [ ] Defaults are in square brackets. COMMANDS Commands are in uppercase letters. italics Command variables, worksheet values, new terms and concepts, and titles of books and periodicals are in italics. Ctrl/X Indicates two keys that you must press simultaneously. Note Provides general information about the current topic. Caution Provides information to prevent damage to equipment. ------------------------------------------------------------ If the no form of the command is not explicitly explained in the description, then it negates the command. EXEC System Use · Enter commands by typing their names at the EXEC prompt and pressing the Return key. · There are two EXEC prompt levels. The user-level prompt is the server name followed by a > as follows: Router> There is also a privileged-level prompt available to the system administrator by entering a password. It is the server name followed by # as follows: Router# · Use the following editing commands when typing commands at the EXEC prompt: ------------------------------------------------------------ Command Function ------------------------------------------------------------ Delete or Backspace Erase characters Ctrl/U Delete line ------------------------------------------------------------ · As a shortcut, you can abbreviate commands to the fewest letters that make them unique. The letters "sho" can be entered for the show command, for example. · Certain EXEC commands display multiple screens with this prompt at the bottom of the screen: --More-- Press the space bar to continue the output; type any other key to return to the prompt. vi System Help · Press the question mark (?) key or the h key (for help) to see a list of available commands at either the user-level or the privileged-level EXEC prompt. · Press the question mark (?) key after certain commands to get more information about them. See the command lists for more information. · At any time during an active Telnet session, you can list the Telnet commands by typing this command at the system prompt: Ctrl ^ ? Press the Ctrl and Shift keys and 6 keys simultaneously, let go, then enter the question mark (?). CONFIGURE Command Use the privileged EXEC command configure to begin configuration of the router. · Begin by entering the privileged level of the EXEC. To do this, type the enable command at the EXEC prompt: Router> enable The EXEC then prompts you for the privileged-level password: Password: · Type the password, taking care to match uppercase and lowercase letters. For security purposes, the password does not appear. When you enter the correct password, the system displays the privileged-level prompt: Router# · To begin configuration mode, enter the configure command at the privileged- level prompt: Router# configure When you enter this command, the EXEC prompts you for the source of the configuration subcommands. Configuring from terminal, memory, ornetwork [terminal]? The default is to type in commands from the terminal console. Pressing the Return key begins this configuration method. · The EXEC provides you with a simple editor for entering the configuration commands and explains the editing functions: Enter configuration commands, one per line. Edit with DELETE, CTRL/W, and CTRL/U; end with CTRL/Z vii The following table lists the edit key functions and their meanings. ------------------------------------------------------------ Key Meaning ------------------------------------------------------------ Delete or Backspace Erases one character Ctrl/W Erases a word Ctrl/U Erases a line Ctrl/R Redisplays a line Return Executes single-line commands Ctrl/Z Ends configuration mode and returns to the EXEC ------------------------------------------------------------ Press Ctrl/Z to end configuration mode. Enter the disable EXEC command to return to the user-level EXEC prompt. Configuration Command Types Configuration commands are categorized by these functions: · Global configuration commands--Define system-wide parameters. · Interface subcommands--Define the characteristics of an interface (a serial or Ethernet interface, for example) and must be preceded by an interface command. · Line subcommands--Define the characteristics of a serial line and must be preceded by a line command. · Router subcommands--Specify a routing protocol (IGRP, OSPF, and so on) and must be preceded by a router command. Observe the following guidelines when you enter configuration commands: · As with EXEC commands, you can type configuration subcommands in uppercase letters, lowercase letters, or both. You also can shorten all commands and other keywords to the fewest number of characters that uniquely identify the word. · To add a comment, begin the line with an exclamation point (!). Comments do not affect command processing. · If the router encounters a problem, it displays an error message on the console terminal. viii 1 ------------------------------------------------------------ System Use Commands 1.1 EXEC Terminal Use Commands ------------------------------------------------------------ {connect | telnet} connection Connects to a remote host using the Telnet protocol. · Connect or telnet -- Use ether of the two keywords. · Connection--Host name or IP address Example connect router ------------------------------------------------------------ disconnect [connection] Closes a connection. · connection--Connection name or number displayed by the SHOW USERS command; the default is the current connection. Example disconnect 2 ------------------------------------------------------------ {exit | quit | logout} Any of these commands terminates the EXEC command processor and closes any active session. ------------------------------------------------------------ name-connection Assigns a logical name to a connection. The EXEC prompts for the connection number and name to assign. ------------------------------------------------------------ System Use Commands 1-1 System Use Commands 1.1 EXEC Terminal Use Commands ------------------------------------------------------------ resume [connection] Resumes a connection. · connection--Connection name or number displayed by the SHOW USERS command; the default is the current connection.

Do not use this command on the DECbrouter 90. You will be unable to boot flash without corrupting your non-volatile RAM. ------------------------------------------------------------ [no] buffers {small | middle | big | large | huge} {permanent | max-free | min-free | initial} number Allows a network administrator to adjust initial buffer pool settings and set limits at which temporary buffers are created and destroyed. The no form with appropriate keywords and arguments restores the default buffer values.
