Filtering output information

Introduction
You can use regular expressions in display commands to filter output information.
The following methods are available for filtering output information:
Enter the begin, exclude, or include keyword plus a regular expression in the display command to
•
filter the output information.
When the system displays the output information in multiple screens, use /, - or + plus a regular
•
expression to filter subsequent output information. / equals the keyword begin, - equals the
keyword exclude, and + equals the keyword include.
The following definitions apply to the begin, exclude, and include keywords:
begin: Displays the first line that matches the specified regular expression and all lines that follow.
•
• exclude: Displays all lines that do not match the specified regular expression.
include: Displays all lines that match the specified regular expression.
•
A regular expression is a case-sensitive string of 1 to 256 characters. It supports the following special
characters.

^string
string$

Remarks
For example, regular expression "^user" matches a
line beginning with "user", not "Auser".
For example, regular expression "user$" matches a
line ending with "user", not "userA".
For example, "s" matches both "as" and "bs".
For example, "zo*" matches "z" and "zoo";
"(zo)*" matches "zo" and "zozo".
For example, "zo+" matches "zo" and "zoo", but
not "z".

Required
By default, a login user uses the
settings of the screen-length
command. The default settings of the
screen-length command are:
multiple-screen display is enabled
and up to 24 lines are displayed on
the next screen.
This command is executed in user
view, and takes effect for the current
user only. When the user re-logs into
the switch, the default configuration
is restored.
