3. Verify that the port configurations are correct:
a. Execute the display interface brief command.
b. Determine whether the speed and duplex mode of the port match the speed and duplex
mode of the peer port.
c. If they do not match, use the speed command and the duplex command to set the speed
and duplex mode for the port.
4. Verify that the port and the link medium are operating correctly:
a. Plug the link medium into another port that is operating correctly, and determine whether the
same problem occurs.
b. If the problem still occurs, verify that the following items are operating correctly:
−
Intermediate links and devices, including optical-to-electrical converters, cable terminal
racks, and transmission devices.
−
Transmission medium, including network cables, optical fibers, and transceiver
modules.
c. Examine the port:
−
If the port is a copper port, directly connect the port to a PC.
−
If the port is a fiber port, replace the transceiver module plugged into the port.
5. Determine whether the port has received a large amount of flow control frames:
a. Use the display interface command to view the number of pause frames.
If the number of pause frames is accumulating, you can determine that the port has sent or
received a large amount of flow control frames.
