When the device is connected to a network, you can use the command display interface in order to view the interface bytes counters for inbound and outbound.
So, issue the command
reset counters interface [ interface-type [ interface-number ] ]
And after that, verify again.
The counters will reflect the statitics according to how much traffic is passing trough.
It is suggested not to make any chagne if considerable traffic is passing. Otherwise, you may take the decission to proceed.
Example:
# Clear traffic statistics on all interfaces.
<HUAWEI> reset counters interface
# Clear traffic statistics on VLANIF10.
<HUAWEI> reset counters interface vlanif 10
