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:
Input 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
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.
Remarks
For example, regular expression "^user" only
matches a string beginning with "user", not
"Auser".
For example, regular expression "user$" only
matches a string ending with "user", not "userA".
For example, ".l" matches both "vlan".
For example, "zo*" matches "z" and "zoo";
"(zo)*" matches "zo" and "zozo".
For example, "zo+" matches "zo" and "zoo", but
not "z".
