Parameters
interface-number: Loopback interface number, which can be the number of any existing loopback
interface. With this argument, this command displays information about a specified loopback interface.
brief: Displays brief interface information. If you do not specify this keyword, the command displays
detailed interface information.
down: Displays information about interfaces in DOWN state and the causes. If you do not specify this
keyword, the command displays information about interfaces in all states.
description: Displays complete interface descriptions. If you do not specify this keyword, the command
displays only the first 27 characters of interface descriptions.
|: Filters command output by specifying a regular expression. For more information about regular
expressions, see Fundamentals Configuration Guide.
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.
regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.
Usage guidelines
If you do not specify the loopback keyword, this command displays information about all interfaces on
the device.
If you specify the loopback keyword without the interface-number argument, this command displays
information about all existing loopback interfaces.
