Parameters
0: Specifies interface Inloopback 0.
brief: Displays brief interface information. If you do not specify this keyword, the command displays
detailed interface information.
description: Displays complete interface descriptions. If you do not specify this keyword, the
command displays only the first 27 characters of interface descriptions. The description of an
inloopback interface is always InLoopBack0 Interface and cannot be configured.
Usage guidelines
If the inloopback keyword is not specified, the command displays information about all interfaces of
the device.
If the inloopback keyword is specified but the 0 keyword is not specified, the command displays
information about interface Inloopback 0. This is because the device has only one inloopback
interface Inloopback 0.
Examples
# Display detailed information about interface Inloopback 0.
<Sysname> display interface inloopback 0

Table 9 Command output
Field Description
Current state
Physical layer state of the interface, which is always
UP
, meaning
that the inloopback interface can receive and transmit packets.
Line protocol state
Data link layer protocol state of the interface, which is always
UP
(spoofing)
.
UP (spoofing)
means that the data link layer protocol
state of the interface is up, but the link is an on-demand link or is not
present.
Description
Description string of the interface, which is always
InLoopBack0
Interface
and cannot be configured.
Bandwidth Expected bandwidth of the interface.
