Utilizing the Command Line Interface
2-12 Managing the XSR
• Command Recall: Non-help commands are stored in the command history list buffer up to the
last 32 commands. You can recall and edit previous commands using shortcut keys. For
example:
Ctrl+p/Ctrl+n will list the previous/next command respectively and can be
applied repeatedly. The up-arrow or down-arrow keys provide the same feature if your
terminal supports these keys.
• Tab C o m pleti o n: Pressing the
TAB key or CTRL+I completes a command. In case of an
ambiguous match, the word is completed up to the character which leads to ambiguity. For
example,
hostname and hostDos share the letters host, so tab completion completes the
“command”
ho to host.
• Carriage Return/Enter: Pressing the carriage return/ENTER key signals the end of a CLI
command.
• Help Symbol: At any point you can enter the
? character to prompt for a list of possible
commands/parameters at a particular mode.
• Error: Proper error messages are displayed if the command could not be issued due to syntax
errors or invalid values made by the user.
Typing these characters will produce output as follows:
XSR#showFIioLLJl
XSR#showFIioLLJl
^
% invalid input detected at '^' marker
XSR#
• CLI Terminal Editing Command Keys: Refer to the following table for these useful shortcuts.
Setting CLI Configuration Modes
The CLI provides modes of operation permitting a subset of commands to be issued from each
mode. Also, you can issue any command and acquire any mode if the command entered or mode
acquired subscribes to the same parent. For example, you can issue the
interface serial
command at Crypto Map mode because both Serial Interface and Crypto Map modes subscribe to
Global (config) mode. Table 2-3 describes a few primary modes of operation.
