Field Description
Description
Description of the interface, which is always
InLoopBack0
Interface
and cannot be configured.
Maximum transmission unit
MTU of the interface, which is always 1536 and cannot be
configured
Physical: InLoopBack The physical type of the interface is inloopback.
Last 300 seconds input rate: 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):
• bytes/sec—Average number of bytes received per second.
• bits/sec—Average number of bits received per second.
• packets/sec—Average number of packets received per
second.
Last 300 seconds output rate: 0
bytes/sec, 0 bits/sec, 0 packets/sec
Average output rate over the last 300 seconds (displayed when the
interface supports traffic statistics collection):
• bytes/sec—Average number of bytes sent per second.
• bits/sec—Average number of bits sent per second.
• packets/sec—Average number of packets sent per second.
Input: 0 packets, 0 bytes, 0 drops
Total number and size (in bytes) of incoming packets of the interface
and the number of dropped packets (displayed when the interface
supports traffic statistics collection).
Output: 0 packets, 0 bytes, 0 drops
Total number and size (in bytes) of outgoing packets of the interface
and the number of dropped packets (displayed when the interface
supports traffic statistics collection).

Brief information on interfaces in route mode:
Link: ADM - administratively down; Stby - standby
Protocol: (s) - spoofing

InLoop0 UP UP(s) --
Table 10 Command output
Field Description
Link
Physical link state of the interface, which is always
UP
, meaning that
the link is physically up.
Protocol
Data link layer protocol state of the interface, which is always
UP(s)
.
UP(s)
represents that the data link layer protocol of the interface is up,
but the link is an on-demand link or does not exist. The
(s)
attribute
represents the spoofing flag. This value is typical of null interfaces and
loopback interfaces.
Primary IP
IP address of the interface.
Because inloopback interfaces do not support CLI configuration, this
field does not display a value.
Description
Description of the interface. Because inloopback interfaces do not
support CLI configuration, this field does not display a value.
