If the loopback keyword is specified but the interface-number argument is not specified, the command
displays information about all existing loopback interfaces.
Examples
# Display detailed information about interface loopback 0.

Description
Physical layer state of the loopback interface:
•
UP—The loopback interface can receive and transmit packets.
•
Administratively DOWN—The interface was manually shut down
by using the shutdown command.
Data link layer protocol state of the interface. UP (spoofing) means that
the data link layer protocol state of the interface is up but the link is an
on-demand link or not present at all.
Description string of the interface.
MTU of the interface.
The interface cannot process Layer 3 packets (displayed when the
interface is not configured with an IP address).
Primary IP address of the interface (displayed when the interface is
configured with a primary IP address).
The physical type of the interface is loopback.
Time when statistics on the logical interface were last cleared by using
the reset counters interface command.
If the statistics of the interface have never been cleared by using the
reset counters interface command since the device started, this field
displays Never.
Average input rate during the last 300 seconds (displayed when the
interface supports traffic statistics collection):
•
packets/sec—Average number of packets received per second.
•
bytes/sec—Average number of bytes received per second.
•
bits/sec—Average number of bits received per second.
