Solution

To resolve the problem:
1. Examine the packet statistics of the port:
a. (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.
b. Determine whether the ports at both ends are always up, and use the display interface
command to determine whether the number of incoming packets is accumulating. At the same
time, examine the outgoing packet statistics of the peer port.
c. View the values of the error packet fields and determine whether the number of error packets
is accumulating.
2. Verify that the port configurations do not affect packet receiving:
