1-10 AR Series Router Reference Manual
Software Release 2.0.1
C613-03018-00 REV A
The router assumes that the width of the terminal screen is 80 characters, and
performs command line wrapping at the 80th column regardless of the setting
of the terminal. The cursor does not need to be at the end of the line for the
command to be executed. The default editing mode is insert mode. Characters
are inserted at the cursor position and any characters to the right of the cursor
are pushed to the right to make room. In overstrike mode, characters are
inserted at the cursor position and replace any existing characters.
Aliases
The command line interface supports aliases. An alias is a short name for an
often-used longer character sequence. When the user presses [Enter] to execute
the command line, the command processor first checks the command line for
aliases and substitutes the replacement text. The command line is then parsed
and processed normally. Alias substitution is not recursive—the command line
is scanned only once for aliases.
Aliases are created and destroyed using the commands:
ADD ALIAS=name STRING=substitution
DELETE ALIAS=name
A list of all the aliases defined on the router and their replacement strings can
be displayed using the command:
SHOW ALIAS
Online Help
Online help is available for all router commands. Typing a question mark “?” at
the end of a partially completed command displays a list of the parameters that
may follow the current command line, with the minimum abbreviations in
uppercase letters (Figure 1-1 on page 1-11). The current command line is then
re-displayed, ready for further input.
