Field Descri
p
tion
current state
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.
Line protocol current state
State of the data link layer protocol. If the link layer protocol state of an
interface is shown as UP but its link is an on-demand link or not present
at all, its protocol attribute includes the spoofing flag.
Description Description string of the interface.
The Maximum Transmit Unit MTU of the interface.
Internet protocol processing: disabled
Indicates that the interface cannot process Layer 3 packets (displayed
when the interface is not configured with an IP address).
Internet Address is 1.1.1.1/32
Primary
Primary IP address of the interface (displayed when the interface is
configured with a primary IP address).
Physical is Loopback The physical type of the interface is loopback.
Last clearing of counters
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.
Last 300 seconds input: 0 bytes/sec,
0 bits/sec, 0 packets/sec
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.
