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 or outgoing packets is
accumulating. At the same time, examine the outgoing or incoming 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 or sending:
a. Use the display interface brief command to verify that the port configurations are correct.
The port configurations include the duplex mode, speed, port type, and VLAN
configurations of the ports at both ends of the link.
b. If configuration errors exist, modify the port configurations. If the number of incoming
packets in the output from the display interface command is accumulating, you can
determine that the port can receive packets.
c. If the port fails to receive packets, use the shutdown command and then the undo
shutdown command to re-enable the port. If the number of incoming packets in the output
