Issue 2 October

18 Preface Document Organization This Converged Network Analyzer (CNA) Command Reference Guide is organized as follows: Chapter 1: Introduction to the Command Line Interface provides an overview of the CLI, including operating modes, levels of access, and organization of commands. Chapter 2: Commands defines all of the commands understood by CNA, including syntax, argument definitions, default values, and a description of what the command does and how it is to be used; commands are presented in alphabetical order. Chapter 3: CNA API describes how to configure CNA from an external process, using the HTTP-based Application Programming Interface (API). For definitions of technical terms and acronyms used in the Replace variable w/ product name documentation set, see the Glossary in the RouteScience PathControl Administrator s Guide. Conventions The following typographical conventions are followed in this document: Text that is displayed on a monitor in a command window is presented in the Courier typeface when shown in isolated paragraphs separated from body text. Within the main body text, bold is used to denote command-line keywords (words that must be entered exactly as shown). Italic text is used to denote command argument names and values, filenames, book titles, and to introduce new terms not commonly understood. Angle brackets ( < and > ) enclose placeholder text that is to be replaced by user-specific data. Curly braces ( { and } ) enclose a range of choices for a required argument. Square brackets ( [ and ] ) enclose optional arguments. When curly braces are used inside square brackets as in this example: [a {b c}] it means that if you choose to set the optional argument a, you must select one of the choices within the curly braces. 18 Converged Network Analyzer (CNA) Command Reference Guide, Version 3.0

19 Conventions See the following table for examples: Convention Courier type bold italics Meaning The Courier type face is used to denote one of the following: Text as displayed on a monitor Command syntax examples. Bold text denotes command keywords Italics can mean any of the following: filenames document titles command argument names and values < > Words enclosed in angle brackets should be replaced by user-specific data. In the following example, the words userid and password should be replaced by actual user ID and password values: Login: <userid> Password: <password> [ ] Square brackets are used to denote command line arguments that are optional. Issue 2 October

20 Preface Convention Meaning { } Curly braces enclose a range of choices for a required argument. When used within square brackets, curly braces indicate that if you choose to set the optional argument indicated by the square brackets, then you must choose one of the choices enclosed in the curly brackets. In the example below, the curly brackets indicate that either in or out is always required for the ip access-group command: ip access-group <name> {in out} In the following example, the version argument is optional for the snmp-serverhost command, but if it is set it must be either 1 or 2c: snmp-serverhost <host-id> [traps inform] [version {1 2c}]...etc. A vertical bar separates multiple choices among arguments. In the following example, the vertical bar indicates that the first argument of the clear prefix command can be either a prefix in standard, dotted-decimal format ( /n) or the keyword all: clear prefix {<prefix> all} [routes-only] The second argument the keyword routes-only is enclosed in square brackets because it is optional. 20 Converged Network Analyzer (CNA) Command Reference Guide, Version 3.0

21 Chapter 1: Introduction to the Command Line Interface Overview User interaction with the Avaya Converged Network Analyzer (CNA) is through the Command Line Interface (CLI). To use the CLI, connect a terminal directly to the serial port of the device running CNA, or use the telnet or ssh protocol to log in from a remote workstation. Terminal Connection If you connect your terminal to the serial port on the Management Processor module, the CLI can be used to execute commands on any of CNA modules. If you connect your terminal to the serial port on any module other than the Management Processor, the CLI will operate in local mode only and commands will apply only to that module. The number of commands that are available to you in local CLI mode are severely reduced from the number of commands that can be executed in system-wide mode. Remote Connection You can also establish a remote connection with the CNA system through the ethernet port on the management module (top port only; the second ethernet port is not supported on any of the CNA modules). The telnet protocol is enabled by default provided there is an enable password defined and a user account has been configured. See the enable password and username commands in Chapter 3, Command Reference. If you prefer a more secure means of communication, you can disable the telnet protocol and enable the ssh protocol. See the ip telnet on and ip ssh on commands. API You can also configure CNA from your client application, using the CNA5 API. See Chapter 2, CNA5 API, for more information. Issue 2 October

22 Introduction to the Command Line Interface CLI Access There are two levels of user access to the CLI: Login initial access level when you first log in to the system Privileged requires the user to execute the enable command (which can be protected by an enable password) Operating Modes Commands are divided into two primary working modes: System operations mode provides access to commands related to the CNA system operating environment; these commands cause something to happen during the current operating session Configuration mode provides access to commands that configure specific functions or system modules; these commands cause the CNA system to add an entry to the current running configuration The configuration mode is further subdivided according to what is being configured: Access lists Interfaces Adaptive Routing Engine module BGP Service Provider access links Analysis and Reporting module USTAT modules Chatter Command Classification Most commands of the CLI are isolated according to operating mode. That is, you must be in a specific mode in order to execute certain commands. There are two exceptions to this general rule: global and local commands. 22 Converged Network Analyzer (CNA) Command Reference Guide, Version 3.0

23 CLI Access Global Commands Some commands are global. These commands can be executed at any time, in any mode: end exit help history logout terminal tree Local Commands Most commands operate on the system as a whole, and any information that is output reflects all modules (or an explicitly identified module). Two commands, however, are local to the module to which you are physically connected: show local-debug tcpdump Information displayed as a result of these commands reflects only the module to which you are connected. Some commands (certain show commands and the ping command) operate both locally and across the system, depending on syntax. These syntax variations will be identified in the reference chapter descriptive text. To find out which commands are available to you at a particular time, enter the global command help or a question mark (? ) on the command line. A list of available commands will be output to your monitor. Changing Modes Use either the exit or end command to return to the previous mode. Use the Control-Z key combination to return to system operations mode. For example, if you are in interface configuration mode (config-if), do either of the following to return to systems operations mode: Ctrl-Z exit to configuration mode and exit again (if you use the exit command one more time, you will be logged off the device) Issue 2 October

24 Introduction to the Command Line Interface Prompts The prompt that is displayed on the command line changes according to access level and operating mode. The prompt always consists of the CNA system s hostname followed by some number of characters indicating access level and mode: a right angle bracket ( > ) indicates login-level access a pound sign ( # ) indicates privileged-level access config in parentheses indicates configuration mode config-acl in parentheses indicates access-list configuration mode config-engine in parentheses indicates Adaptive Routing Engine configuration mode config-engine-active in parentheses indicates active measurement group configuration mode config-engine-bgp in parentheses indicates BGP configuration mode config-engine-link in parentheses indicates service provider access link configuration mode config-engine-policy in parentheses indicates policy configuration mode config-if in parentheses indicates interface configuration mode config-polling-snmp in parentheses indicates polling-agent configuration mode config-report in parentheses indicates analysis and reporting configuration mode config-ustat in parentheses indicates USTAT configuration mode config-chatter in parentheses indicates chatter configuration mode For a system whose host name is hostname, prompts would look as shown in Table 1.

The following subset of system-operations commands are available to you: date enable eventdump ls ping show tcpdump time traceroute In order to use the remaining system operations commands, you must execute the enable command to gain privileged-level access. At this level, the following system-operations commands are available to you: backup clear configure copy date debug delete disable enable erase eventdump export halt ip ssh key generate 26 Converged Network Analyzer (CNA) Command Reference Guide, Version 3.0

27 Configuration Commands ls medic more ping recover reload rename restore resync rsync show ssl add ssl delete tcpdump time traceroute write Configuration Commands When you execute the configure terminal command, the system will be placed in configuration mode (config). While you are in any of the configuration modes, none of the system operations commands are available to you (but global commands are). The following commands are available to you only in configuration mode: aaa chatter contact enable hostname interface ip access-list ip domain-lookup ip domain-name ip ftp password ip ftp username ip host ip http server header append ip http password ip http server header append ip http server on ip http server ssl on ip http username ip name-server ip route ip ssh on ip telnet on logging Issue 2 October
