Display Interface Null - H3C S5120-SI Series Command Reference Manual

Table 1-1 display interface loopback command output description
current state
Line protocol current state
Description
The Maximum Transmit Unit
Internet protocol processing
Physical is Loopback
Last clearing of counters
Last clearing of counters
Last 300 seconds input: 0 bytes/sec 0
bits/sec 0 packets/sec
Last 300 seconds output: 0 bytes/sec
0 bits/sec 0 packets/sec
0 packets input, 0 bytes, 0 drops
0 packets output, 0 bytes, 0 drops
Because the S5120-SI switch series do not count the average input/output rate or input/output packets
of a loopback interface, these fields are displayed as "0" in the display interface loopback command
output.

Syntax
display interface null [ 0 ]
Field Description
Physical state of the interface (up or administratively down)
State of the data link layer protocol: up
Description string of the interface
Maximum transmit unit (MTU) of the interface
State of the network layer protocol (enabled or disabled)
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 starts, Never is displayed for this field.
Time when the statistics on the logical interface was last
cleared
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 second.
bits/sec indicates the average number of bits received
per second.
Average output rate over the last 300 seconds, where:
packets/sec indicates the average number of packets
sent per second.
bytes/sec indicates the average number of bytes sent
per second.
bits/sec indicates the average number of bits sent per
second.
Total number and size (in bytes) of the input packets of the
interface and the number of the dropped packets
