Field Description
current state Physical state (up or administratively down) of the interface
Line protocol current state
State of the data link layer protocol: up (spoofing). Spoofing
refers to the spoofing attribute of the interface. When the network
layer protocol state of the interface is displayed as up, the
corresponding link may not exist, or the corresponding link is
non-permanent and established on demand.
Description Description string of the interface
The Maximum Transmit Unit Maximum transmit unit (MTU) of the interface
Internet protocol processing
State of the network layer protocol, which can be disabled or
enabled (displayed as Internet Address is
X.X.X.X/XX Primary)
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,
Never is displayed for this field.
Last 300 seconds input: 0 bytes/sec, 0
bits/sec, 0 packets/sec
Average input rate over the last 300 seconds, where:
• packets/sec indicates the average number of packets
received per second.
• bytes/sec indicates the average number of bytes received per
