Solution
To resolve the issue:
1.
(Optional.) Use the
reset counter interface
command in user view to clear the packet statistics
of the port.
This command resets the values of each statistical field to 0, so that you can view the statistics
changes more clearly.
2.
If the port is a fiber port, verify that the optical power of the transceiver module is operating
correctly:
a.
Use the
display transceiver diagnosis interface
command in probe view to view the
present measured values of the digital diagnosis parameters for the transceiver module.
b.
If the optical power of the transceiver module is not within the correct range, replace the
transceiver module with a transceiver module of the same model that is operating correctly.
[Sysname-probe] display transceiver diagnosis interface ten-gigabitethernet 1/0/1
Replace it with a transceiver
module with correct optical
power
