Parameters 

interface-number

: Specifies a loopback interface by its number, which can be the number of any 

existing loopback interface. If you do not specify the 

interface-number 

argument, the command 

clears the statistics on all loopback interfaces. 

Usage guidelines 

To determine whether a loopback interface works correctly within a period by collecting the traffic 
statistics within that period, first use the 

reset counters interface

 [ 

loopback

 [ 

interface-number 

] ] 

command to clear the statistics. Then have the interface automatically collect the statistics. 

This command is available only if at least one loopback interface has been created. 

Examples 

# Clear the statistics on loopback interface Loopback 1. 

<Sysname> reset counters interface loopback 1 

Related commands 

display interface loopback

 

reset counters interface null 

Use 

reset counters interface null

 to clear the statistics on the null interface.

Parameters 

0

: Specifies the number of the null interface, which is always 0. 

Usage guidelines 

To determine whether the null interface works correctly within a period by collecting the traffic 
statistics within that period, first use the 

reset counters interface

 [ 

null

 [ 

0
