The LightStream 1010 Asynchronous Transfer Mode (ATM) switch command line interface (CLI) provides access to several different command modes. Each of the six different command modes provide a different group of related commands. Users familiar with the Cisco Internetwork Operating System (Cisco IOS) user interface will find the commands very similar. This chapter describes how to access and list the commands available in each command mode and explains the primary uses for each command mode.
For security purposes, the user interface provides two levels of access to commands: user and privileged. The unprivileged user mode is called user EXEC mode. The privileged mode is called privileged EXEC mode, and requires a password. The commands available in user EXEC mode are a subset of the commands available in privileged EXEC mode.
From the privileged level, you can access global configuration mode and three specific configuration modes: terminal, memory, and network configuration. In addition, if your switch does not find a valid system image, or if its configuration file is corrupted at startup, the system might enter read-only memory (ROM) monitor mode. Entering a question mark (?) at the system prompt allows you to obtain a list of commands available for each command mode.
Almost every switch configuration command also has a no form. In general, use the no form to disable a feature or function. Use the command without the keyword no to reenable a disabled feature or to enable a feature that is disabled by default. For example, terminal history is enabled by default. Specify the command no history to disable terminal history and specify terminal history to reenable it. The LightStream 1010 ATM Switch Command Reference publication provides the complete syntax for every switch configuration command and describes what the no form of a command does.
The user interface also provides context-sensitive help on command syntax. This chapter describes how to use the help system. It also describes the command editing and command history features that enable you to recall previous command entries and easily edit command entries.
For a complete description of the commands mentioned in this chapter, refer to the LightStream 1010 ATM Switch Command Reference publication.
You can perform the tasks in the following sections to become familiar with the LightStream 1010 ATM switch user interface:
This section describes how to access each of the LightStream 1010 ATM switch command modes:
Table 5-1 lists the command modes, how to access each mode, the prompt you will see while you are in that mode, the main uses for each configuration mode, and the method to exit that mode. The prompts listed assume the default switch name "Switch." Table 5-1 might not include all the possible ways to access or exit each command mode.
After you log in to the switch, you are automatically in user EXEC command mode. The EXEC commands available at the user level are a subset of those available at the privileged level. In general, the user EXEC commands allow you to connect to remote switches, change terminal settings on a temporary basis, perform basic tests, and list system information.
The user-level prompt consists of the switch's host name followed by the angle bracket (>):
Switch>
The default host name is Switch unless it has been changed during initial configuration using the setup command. (Refer to the LightStream 1010 ATM Switch Software Configuration Guide for information on the setup facility.) You can also change the switch name using the hostname global configuration command described in the "System Management Commands" chapter in the LightStream 1010 ATM Switch Software Configuration Guide publication.
To list the commands available in user EXEC mode, enter a question mark (?) as shown in the following example:
Switch>? Exec commands: access-enable Create a temporary Access-List entry atmsig Execute Atm Signalling Commands cd change current device clear Reset functions connect Open a terminal connection dir List files on given device disable Turn off privileged commands disconnect Disconnect an existing network connection enable Turn on privileged commands exit Exit from the EXEC help Description of the interactive help system lock Lock the terminal login Log in as a particular user logout Exit from the EXEC name-connection Name an existing network connection ping Send echo messages ppp Start IETF Point-to-Point Protocol (PPP) pwd Display current device resume Resume an active network connection show Show running system information slip Start Serial-line IP (SLIP) systat Display information about terminal lines telnet Open a telnet connection terminal Set terminal line parameters traceroute Trace route to destination where List active connections Switch>
The list of commands might vary slightly from this example, depending on the software feature set and configuration of your switch.
If your switch does not find a valid system image, or if you interrupt the boot sequence, the system might enter ROM monitor mode. From ROM monitor mode, you can boot the switch or perform diagnostic tests.
You can also enter ROM monitor mode by entering the reload EXEC command and then pressing the Break key during the first 60 seconds of startup. To save changes to the configuration file, use the copy running-config startup-config command before issuing the reload command.
To access and list the ROM monitor configuration commands, complete the following tasks:
| Task | Command |
|---|---|
| Enter ROM monitor mode from privileged EXEC mode | reload1 Press Break key during the first 60 seconds while the system is booting |
| List the ROM monitor commands | ? |
The ROM monitor prompt is the angle bracket (>):
rommon 1> help alias set and display aliases command boot boot up an external process break set/show/clear the breakpoint confreg configuration register utility cont continue executing a downloaded image context display the context of a loaded image dev list the device table dir list files in file system dis disassemble instruction stream dnld serial download a program module frame print out a selected stack frame help monitor builtin command help history monitor command history meminfo main memory information repeat repeat a monitor command reset system reset set display the monitor variables stack produce a stack trace sync write monitor environment to NVRAM sysret print out info from last system return unalias unset an alias unset unset a monitor variable rommon 3 >
To initialize the switch, enter the b command. To boot the system image file, use the b command (described in the chapter "Loading System Images, Software Images, and Configuration Files").
Because many of the privileged commands set operating parameters, privileged access should be password-protected to prevent unauthorized use. The privileged command set includes those commands contained in user EXEC mode, as well as the configure command through which you can access the remaining command modes. Privileged EXEC mode also includes high-level testing commands, such as debug. For details on the debug commands, see the LightStream 1010 ATM Switch Software Configuration Guide and LightStream 1010 ATM Switch Command Reference publications.
To access and list the privileged EXEC commands, complete the following tasks:
| Task | Command |
|---|---|
| Enter the privileged EXEC mode | enable [password] |
| List privileged EXEC commands | ? |
If the system administrator has set a password, you are prompted to enter it before being allowed access to privileged EXEC mode. The password is not displayed on the screen and is case sensitive. If an enable password has not been set, enabled mode can be accessed only from the console. The system administrator uses the enable password global configuration command to set the password that restricts access to privileged mode. This command is described in the Lightstream 1010 ATM Switch Command Reference publication.
The privileged EXEC mode prompt consists of the switch's host name followed by the pound sign (#). (If the switch was named with the hostname command, that name would appear as the prompt instead of "Switch.")
Switch#
The following example shows how to access privileged EXEC mode and list privileged EXEC commands:
Switch>enablePassword: Switch#?Exec commands: atmsig Execute Atm Signalling Commands calendar Manage the hardware calendar cd change current device clear Reset functions clock Manage the system clock configure Enter configuration mode connect Open a terminal connection copy Copy configuration or image data debug Debugging functions (see also 'undebug') delete Delete a file dir List files on given device disable Turn off privileged commands disconnect Disconnect an existing network connection enable Turn on privileged commands erase Erase flash or configuration memory exit Exit from the EXEC format format a device help Description of the interactive help system lock Lock the terminal login Log in as a particular user logout Exit from the EXEC name-connection Name an existing network connection no Disable debugging functions ping Send echo messages ppp Start IETF Point-to-Point Protocol (PPP) pwd Display current device reload Halt and perform a cold restart resume Resume an active network connection rsh Execute a remote command send Send a message to other tty lines setup Run the SETUP command facility show Show running system information slip Start Serial-line IP (SLIP) squeeze Squeeze a device start-chat Start a chat-script on a line systat Display information about terminal lines telnet Open a telnet connection terminal Set terminal line parameters test Test subsystems, memory, and interfaces traceroute Trace route to destination undebug Disable debugging functions (see also 'debug') undelete Undelete a file verify Verify checksum of a Flash file where List active connections write Write running configuration to memory, network, or terminal
The list of commands might vary slightly from this example, depending on the software feature set and configuration of your switch.
From the privileged level, you can access global configuration mode. For instructions, see the "Global Configuration Mode" section, which follows this section.
To return from privileged EXEC mode to user EXEC mode, perform the following task:
| Task | Command |
|---|---|
| Move from privileged EXEC mode to user EXEC mode | disable |
Global configuration commands apply to features that affect the system as a whole. Use the configure privileged EXEC command to enter global configuration mode. When you enter this command, the EXEC prompts you for the source of the configuration commands:
Configuring from terminal, memory, or network [terminal]?
You can then specify either the terminal, nonvolatile RAM (NVRAM), or a file stored on a network server as the source of configuration commands. (See the "System Image, Software Image, and Configuration File Load Commands" chapter in the LightStream 1010 ATM Switch Software Configuration Guide publication.) The default is to enter commands from the terminal console. Pressing the Return key begins this configuration method.
To access and list the global configuration commands, complete the following tasks:
| Task | Command |
|---|---|
| At the terminal, from the privileged EXEC mode, enter global configuration mode | configure1 <CR> |
| List the global configuration commands | ? |
The following example shows how to access global configuration mode and list global configuration commands:
Switch#configureConfiguring from terminal, memory, or network [terminal]?<CR>Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#?Configure commands: aaa Authentication, Authorization and Accounting. access-list Add an access list entry alias Create command alias arp Set a static ARP entry async-bootp Modify system bootp parameters atm ATM Global Cofiguration Commands banner Define a login banner boot Modify system boot parameters buffers Adjust system buffer pool parameters cdp Global CDP configuration subcommands chat-script Define a modem chat script clock Configure time-of-day clock config-register Define the configuration register default-value Default character-bits values dialer-list Create a dialer list entry dnsix-dmdp Provide DMDP service for DNSIX dnsix-nat Provide DNSIX service for audit trails downward-compatible-config Generate a configuration compatible with older software enable Modify enable password parameters end Exit from configure mode exit Exit from configure mode help Description of the interactive help system hostname Set system's network name interface Select an interface to configure ip Global IP configuration subcommands line Configure a terminal line logging Modify message logging facilities map-class Configure static map class map-list Configure static map list network-clock-select Network clock select no Negate a command or set its defaults ntp Configure NTP privilege Command privilege parameter route-map Create route-map or enter route-map command mode router Enable a routing process scheduler Scheduler parameters service Modify use of network based services snmp-server Modify SNMP parameters tacacs-server Modify TACACS query parameters tftp-server Provide TFTP service for netload requests username Establish User Name Authentication
The list of commands might vary slightly from this example, depending on the software feature set and configuration of your switch.
To exit global configuration command mode and return to privileged EXEC mode, use one of the following commands:
| Task | Command |
|---|---|
| Exit global configuration mode | exit end Ctrl-Z |
From global configuration mode, you can access 16 configuration modes containing interface, subinterface, and line configuration commands. These command modes are described in the following sections.
Many features are enabled on a per-interface basis. Interface configuration commands modify the operation of an interface such as an ATM, Ethernet, or asynchronous port. Interface configuration commands always follow an interface global configuration command that defines the interface type.
To access and list the interface configuration commands, complete the following tasks:
| Task | Command |
|---|---|
| From global configuration mode, enter interface configuration mode | interface type card/sub_card/port1 |
| List the interface configuration commands | ? |
In the following example, ATM interface 1/0/0 is about to be configured. The new prompt Switch(config-if)# indicates interface configuration mode. In this example, the user asks for help by requesting a list of commands.
Switch# Switch#config terminal Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#interface atm 1/0/0 Switch(config-if)#? Interface configuration commands: arp Set arp type (arpa, probe, snap) or timeout asig ATM Signalling Interface Subcommands atm Modify ATM parameters bandwidth Set bandwidth informational parameter cdp CDP interface subcommands clock-source Configure OC3 tx clock source custom-queue-list Assign a custom queue list to an interface delay Specify interface throughput delay description Interface specific description exit Exit from interface configuration mode help Description of the interactive help system hold-queue Set hold queue depth keepalive Enable keepalive load-interval Specify interval for load calculation for an interface loopback Configure internal loopback on an interface map-group Configure static map group mtu Set the interface Maximum Transmission Unit (MTU) no Negate a command or set its defaults ntp Configure NTP priority-group Assign a priority group to an interface scrambling Configure SONET scrambling shutdown Shutdown the selected interface snmp Modify SNMP interface parameters sonet Configure OC3 SONET mode transmit-interface Assign a transmit interface to a receive-only interface tx-queue-limit Configure card level transmit queue limit Switch(config-if)#
The list of commands might vary slightly from this example, depending on the software feature set and configuration of your switch.
To exit interface configuration mode and return to global configuration mode, enter the exit command. To exit configuration mode and return to privileged EXEC mode, use the end command or press Ctrl-Z.
You can configure multiple logical interfaces (called subinterfaces) on a single ATM interface or ATM Switch Processor (ASP) Ethernet interface.
Subinterfaces appear to be distinct physical interfaces to the various protocols. For example, ATM networks provide multiple point-to-point links called permanent virtual circuits (PVCs). PVCs can be grouped under separate subinterfaces that in turn are configured on a single physical interface.
To access and list the subinterface configuration commands, complete the following tasks:
| Task | Command |
|---|---|
| From interface configuration mode, configure a logical interface | interface atm card/sub_card/port [.sub-inter #]1 interface ethernet 2/0/0 [.sub-inter #] |
| List the subinterface configuration commands | ? |
In the following example, an interface is configured for ATM 0/0/0. The subinterface is number 99 to indicate that it is subinterface 99 of port 0 on the port adapter module (PAM) 0 in carrier module (CAM in slot 0). The new prompt Switch(config-subif)# indicates subinterface configuration mode. The subinterface can be configured to support one or more ATM PVCs. To list the commands available in subinterface configuration mode, enter a question mark (?).
Switch(config)#interface atm 0/0/0.99 Switch(config-subif)#? Interface configuration commands: atm ATM Interface ILMI Config Commands bandwidth Set bandwidth informational parameter cdp CDP interface subcommands delay Specify interface throughput delay description Interface specific description exit Exit from interface configuration mode map-group Configure static map group no Negate a command or set its defaults ntp Configure NTP shutdown Shutdown the selected interface Switch(config-subif)#
In the following example an interface is configured for Ethernet 2/0/0. The subinterface is number 100 of ASP CPU interface 2/0/0. The new prompt Switch(config-subif)# indicates subinterface configuration mode. The subinterface can be configured to support one or more Ethernet PVCs.
To list the commands available in subinterface configuration mode, enter a question mark (?).
Switch(config)#inter ether 2/0/0.100 Switch(config-subif)#? Interface configuration commands: backup Modify dial-backup parameters bandwidth Set bandwidth informational parameter cdp CDP interface subcommands delay Specify interface throughput delay description Interface specific description encapsulation Set encapsulation type for an interface exit Exit from interface configuration mode ip Interface Internet Protocol config commands no Negate a command or set its defaults shutdown Shutdown the selected interface Switch(config-subif)#
To exit subinterface configuration mode and return to global configuration mode, enter the exit command. To exit configuration mode and return to privileged EXEC mode, press Ctrl-Z.
Line configuration commands modify the operation of a terminal line. Line configuration commands always follow a line command, which defines a line number. These commands are generally used to connect to remote switches, change terminal parameter settings either on a line-by-line basis or for a range of line, and set up the auxiliary port modem configuration. For detailed line configuration instructions, see the chapter "Configuring Terminal Lines and Modem Support."
To access and list the auxiliary port, console port, and virtual terminal line configuration commands, complete the following tasks:
| Task | Command |
|---|---|
| From global configuration mode, configure an auxiliary, console, or virtual terminal line | line {aux | con | vty} line-number [ending-line-number]1 |
| List the line configuration commands | ? |
The following example shows how to enter line configuration mode for the console line and list the line configuration commands. The new prompt Switch(config-line)# indicates line configuration mode.
Switch(config)#line console 0
Switch(config-line)#?

The LightStream 1010 ATM switch supports a static mapping scheme that identifies the ATM address of remote hosts or switches.
Map-list configuration commands configure a map list. They always follow a map-list global configuration command. To access and list the map list configuration commands, complete the following tasks:
| Task | Command |
|---|---|
| From global configuration mode, use the map-list command | map-list name 1 |
| List the map-list configuration commands | ? |
The following example shows how to enter map-list configuration mode and list the map list configuration commands. In this example, the static map-list configuration commands are listed. The new prompt Switch(config-map-list)# indicates map-list configuration mode.
Switch(config)# map-list 1 Switch(config-map-list)# ? Static maps list configuration commands: A.B.C.D Protocol specific address arp IP ARP cdp Cisco Discovery Protocol compressedtcp Compressed TCP exit-class Exit from static map class configuration mode help Description of the interactive help system ip IP no Negate or set default values of a command Switch(config-map-list)#
To exit map-list configuration mode and return to global configuration mode, enter the exit command. To exit configuration mode and return to privileged EXEC mode, use the end command or press Ctrl-Z.
The ATM interface allows you to specify quality of service (QOS) parameters that control how much traffic the source switch will be sending over a switched virtual circuit (SVC).
To define QOS parameters that are associated with a static map for an SVC, use the map-class global configuration command.
| Task | Command |
|---|---|
| From global configuration mode, configure an ATM map class | map-class atm class-name1 |
| List the map-class configuration commands | ? |
In the following example, the static map-class configuration commands are listed. The prompt Switch(config-map-class)# indicates map-class configuration mode.
Switch(config)# map-class atm example Switch(config-map-class)# ? Static maps class configuration commands: atm Configure atm static map class dialer Configure dialer static map class exit-class Exit from static map class configuration mode help Description of the interactive help system no Negate or set default values of a command Switch(config-map-class)#
To exit map-class configuration mode and return to global configuration mode, enter the exit command. To exit configuration mode and return to privileged EXEC mode, use the end command or press Ctrl-Z.
The LightStream 1010 ATM switch supports the Private Network-Network Interface (PNNI) routing protocol. The atm router pnni command entered from privileged EXEC command mode allows you to change to PNNI router configuration mode.
To access and list the atm router pnni configuration commands, complete the following tasks:
| Task | Command |
|---|---|
| From global configuration mode, use the atm router pnni command. | atm router pnni 1 |
| List the ATM router PNNI configuration commands. | ? |
The following example shows how to enter ATM router PNNI configuration mode and list the ATM router PNNI configuration commands. The new prompt Switch(config-atm-router)# indicates ATM router PNNI configuration mode.
Switch(config)#atm router pnni
Switch(config-atm-router)#?

Switch(config-atm-router)#
To exit ATM router configuration mode and return to global configuration mode, enter the exit command. To exit configuration mode and return to privileged EXEC mode, use the end command or press Ctrl-Z.
The LightStream 1010 ATM switch supports the PNNI routing protocol. The ATM router PNNI node command entered from ATM router PNNI command mode allows you to change to node configuration mode.
To access and list the ATM router PNNI node configuration commands, complete the following tasks:
| Task | Command |
|---|---|
| From ATM router PNNI configuration mode, use the node command. | node index_number1 |
| List the ATM router PNNI node configuration commands. | ? |
The following example shows how to enter ATM router PNNI node configuration mode for PNNI node index number one and list the ATM router PNNI node configuration commands. The new prompt Switch(config-pnni-node)# indicates ATM router PNNI node configuration mode.
Switch(config-atm-router)#node 1 Switch(config-pnni-node)#? PNNI router node configuration commands: auto-summary Automatically summarize switch address prefix exit Exit from PNNI router node configuration mode name Configure Node's Name no Negate or set default values of a command ptse PTSE generation parameters redistribute Route redistribution from another routing protocol summary-address Summarize reachable addresses into PNNI timer PNNI timer variables transit-restricted Transit calls are not allowed Switch(config-pnni-node)#
To exit ATM router node configuration mode and return to global configuration mode, enter the exit command. To exit configuration mode and return to privileged EXEC mode, use the end command or press Ctrl-Z.
The previous sections described the first level of help available with the user interface. Entering a question mark (?) at the system prompt displays a list of commands available for each command mode. You can also get a list of any command's associated keywords and arguments with the context-sensitive help feature.
To get help specific to a command mode, a command, a keyword, or arguments, perform one of the following tasks:
| Task | Command |
|---|---|
| Obtain a brief description of the help system in any command mode | help |
| Configure a line or lines to receive help for the full set of user-level commands when a user presses ? | full-help |
| Configure a line to receive help for the full set of user-level commands for this EXEC session | terminal full-help1 |
| Obtain a list of commands that begin with a particular character string | abbreviated-command-entry? |
| Complete a partial command name | abbreviated-command-entry<Tab> |
| List all commands available for a particular command mode | ? |
| List a command's associated keywords | command ? |
| List a keyword's associated arguments | command keyword ? |
When using context-sensitive help, the space (or lack of a space) before the question mark (?) is significant. To obtain a list of commands that begin with a particular character sequence, type in those characters followed immediately by the question mark (?). Do not include a space. This form of help is called word help, because it completes a word for you.
To list keywords or arguments, enter a question mark (?) in place of a keyword or argument. Include a space before the ?. This form of help is called command syntax help, because it reminds you which keywords or arguments are applicable based on the command, keywords, and arguments you already have entered.
You can abbreviate commands and keywords to the number of characters that allow a unique abbreviation. For example, you can abbreviate the show command to sh.
Enter the help command (which is available in any command mode) for a brief description of the help system:
Switch#helpHelp may be requested at any point in a command by enteringa question mark '?'. If nothing matches, the help list willbe empty and you must back up until entering a '?' shows theavailable options.Two styles of help are provided:1. Full help is available when you are ready to enter acommand argument (e.g. 'show ?') and describes each possibleargument.2. Partial help is provided when an abbreviated argument is enteredand you want to know what arguments match the input(e.g. 'show pr?'.)
As described in the help command output, you can enter a partial command name and a question mark (?) to obtain a list of commands beginning with a particular character set. See the section "Completing a Partial Command Name" in the chapter "Understanding the User Interface" of the LightStream 1010 ATM Switch Software Configuration Guide publication for more detail.
The following example illustrates how the context-sensitive help feature enables you to create an access list from configuration mode. First enter the letters co at the system prompt followed by a question mark (?). Do not leave a space between the last letter and the question mark (?). The system provides the commands that begin with co.
Switch#co?
configure connect copy
Enter the configure command followed by a space and a question mark (?) to list the command's keywords and a brief explanation:
Switch#configure ?
memory Configure from NV memory
network Configure from a TFTP network host
overwrite-network Overwrite NV memory from TFTP network host
terminal Configure from the terminal
<cr>
Switch#configure
Enter the terminal keyword to enter configuration mode from the terminal:
Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#
Enter the access-list command followed by a space and a question mark (?) to list the command's keywords:
Switch(config)# access-list ?
<1-99> IP standard access list
<100-199> IP extended access list
Enter the access list number 99 and then enter another question mark (?) to see the arguments that apply to the keyword and brief explanations:
Switch(config)#access-list 99 ?
deny Specify packets to reject
permit Specify packets to forward
Enter the deny argument followed by a question mark (?) to list additional options:
Switch(config)#access-list 99 deny ? Hostname or A.B.C.D Address to match any Any source host host A single host address
Enter the IP address followed by a question mark (?) to list additional options:
Switch(config)#access-list 99 deny 131.108.134.0 ? A.B.C.D Wildcard bits <cr>
The <cr> symbol appears in the list, indicating that one of your options is to press Return to execute the command. The other option is to add a wildcard mask. Enter the wildcard mask followed by a question mark (?) to list further options.
Switch(config)#access-list 99 deny 131.108.134.0 0.0.0.255 ? <cr> Switch(config)#access-list 99 deny 131.108.134.0 0.0.0.255
The <cr> symbol by itself indicates there are no more keywords or arguments. Press Return to execute the command. The system adds an entry to access list 99 that denies access to all hosts on subnet 131.108.134.0.
For a complete description of the user interface and configuration modes, see the following sections of the LightStream 1010 ATM Switch Software Configuration Guide publication:
After using the setup command or other configuration commands, exit the switch and quit the session.
To end a session, perform the following steps:
| Task | Command |
|---|---|
| Enter the quit EXEC command | quit |
Refer to the LightStream 1010 ATM Switch Software Configuration Guide for more information on exiting sessions and closing connections.
