Basic Command Reference

See the description for the admin-password command. If the admin-password is configured in the config>system>security>password context, then any user can enter a special administrative mode by entering the enable-admin command.

The enable-admin command is in the default profile. By default, all users are given access to this command.

Once the enable-admin command is entered, the user is prompted for a password. If the password matches, the user is given unrestricted access to all the commands.

The minimum length of the password is determined by the minimum-length command. The complexity requirements for the password is determined by the complexity command.

The following displays an example of the password command usage.

The following example displays the password configuration:

There are two ways to verify that a user is in the enable-admin mode:

This command moves the context back one level of the command hierarchy. For example, if the current level is the config router mpls context, the back command moves the cursor to the config router context level.

This command clears statistics for a specified entity or clears and resets the entity.

This command echoes arguments on the command line. The primary use of this command is to allow messages to be displayed to the screen in files executed with the exec command.

This command executes the contents of a text file as if they were CLI commands entered at the console.

Exec commands do not have no versions.

Related commands are:

This command returns to the context from which the current level was entered. For example, if you navigated to the current level on a context by context basis, then the exit command only moves the cursor back one level.

If you navigated to the current level by entering a command string, then the exit command returns the cursor to the context in which the command was initially entered.

The exit all command moves the cursor all the way back to the root level.

This command provides a brief description of the help system. The following information is displayed:

This command lists the last 30 commands entered in this session.

Re-execute a command in the history with the !n command, where n is the line number associated with the command in the history output.

For example:

This command displays the running configuration for the configuration context.

The output of this command is similar to the output of a show config command. This command, however, lists the configuration of the context where it is entered and all branches below that context level.

For example:

By default, the command only enters the configuration parameters that vary from the default values. The detail keyword causes all configuration parameters to be displayed.

This command logs out of the router session.

When the logout command is issued from the console, the login prompt is displayed and any log IDs directed to the console are discarded. When the console session resumes (regardless of the user), the log output to the console resumes.

When a Telnet session is terminated from a logout command, all log IDs directed to the session are removed. When a user logs back in, the log IDs must be recreated.

This command changes a user CLI login password.

When a user logs in after the administrator forces a new-password-at-login, or the password has expired (aging), then this command is automatically invoked.

When invoked, the user is prompted to enter the old password, the new password, and then the new password again to verify the correct input.

If a user fails to create a new password after the administrator forces a new-password-at-login or after the password has expired, the user is not allowed access to the CLI.

This command is the TCP/IP utility to verify IP reachability.

This command displays the present or previous working context of the CLI session.

The pwc command provides a user who is in the process of dynamically configuring a chassis a way to display the current or previous working context of the CLI session. The pwc command displays a list of the CLI nodes that hierarchically define the current context of the CLI instance of the user.

For example:

When the previous keyword is specified, the previous context is displayed. This is the context entered by the CLI parser upon execution of the exit command. The current context of the CLI is not affected by the pwc command.

This command causes the console session to pause operation (sleep) for 1 second (default) or for the specified number of seconds.

This command opens a Secure Shell (SSH) session with another host.

This command initiates a client SSH session with the remote host and is independent from the administrative or operational state of the SSH server. However, to be the target of an SSH session, the SSH server must be operational.

Quitting SSH while in the process of authentication is accomplished by either executing a <Ctrl-c> or "~." (tilde and dot) assuming the “~” is the default escape character for the SSH session.

This command opens a Telnet session to a remote host.

Telnet servers in 7705 SAR networks limit a Telnet client to three retries to log in. The Telnet server disconnects the Telnet client session after three retries. The number of retry attempts for a Telnet client session is not user-configurable.

The TCP/IP traceroute utility determines the route to a destination address. Note that aborting a traceroute with the <Ctrl-c> command could require issuing a second <Ctrl-c> command before the prompt is returned.

This command displays the command hierarchy structure from the present working context.

This command sends a console message to a specific user or to all users with active console sessions.

This command enables the substitution of a command line by an alias.

Use the alias command to create alternative names for an entity or command string that are easier to understand and remember. If the string contains special characters (#, $, spaces, etc.), the entire string must be enclosed within double quotes. Only a single command can be present in the command string.

The alias command can be entered in any context but must be created in the root>environment context.

For example, to create an alias named soi to display MPLS interfaces, enter:

alias soi “show router mpls interface”

By default, the create command is required to create a new OS entity.

The no form of the command disables requiring the create keyword.

This command enables per-screen CLI output, meaning that the output is displayed on a screen-by-screen basis. The terminal screen length can be modified with the terminal command.

The following prompt appears at the end of each screen of paginated output:

The no form of the command displays the output all at once. If the output length is longer than one screen, the entire output will be displayed, which may scroll the screen.

This command configures the maximum number of higher CLI context levels to display in the CLI prompt for the current CLI session. This command is useful when configuring features that are several node levels deep, which can cause the CLI prompt to become too long.

By default, the CLI prompt displays the system name and the complete context in the CLI.

The number of nodes specified indicates the number of higher-level contexts that can be displayed in the prompt.

For example, if reduced-prompt is set to 2, the two highest contexts from the present working context are displayed by name with the hidden (reduced) contexts compressed into a ellipsis (“…”).

Note that the setting is not saved in the configuration. It must be reset for each CLI session or stored in an exec script file.

The no form of the command reverts to the default.

This command enables a saved indicator in the prompt. When changes are made to the configuration file, a “*” appears in the prompt string indicating that the changes have not been saved. When an admin save command is executed, the “*” disappears.

This command enables the context to configure the terminal screen length for the current CLI session.

This command sets the terminal screen length (number of lines).

This command displays timestamps in the CLI session based on local time or Coordinated Universal Time (UTC).

The system keeps time internally in UTC and is capable of displaying the time in either UTC or local time based on the time zone configured.

This configuration command is only valid for times displayed in the current CLI session. This includes displays of event logs, traps and all other places where a timestamp is displayed.

In general, all timestamps are shown in the time selected. This includes log entries destined for console/session, memory, or SNMP logs. Log files on compact flash are maintained and displayed in UTC format.

This command displays timestamps before the CLI prompt, indicating the last time that the command was completed. The date and time are displayed; the time format is either local or UTC, depending on how it was set with the time-display command.
