Solution
To resolve the problem:
1.
Verify that the speed and duplex mode of the local port match the speed and duplex mode of the
peer port:
a.
Execute the display interface brief command to examine whether the speed and duplex mode
of the port match the speed and duplex mode of the peer port.
b.
If they do not match, use the speed command and the duplex command to set the speed and
duplex mode for the port.
2.
Verify that the speed and duplex mode of the port match the speed and duplex mode of the
transceiver module:
a.
Execute the display interface brief command to examine whether the speed and duplex mode
of the port match the speed and duplex mode of the transceiver module.
b.
If they do not match, use the speed command and the duplex command to set the speed and
duplex mode for the port.
3.
Verify that the local and peer ports are operating correctly:
a.
Use a 10-Gigabit SFP+ cable to directly connect the local port and another 10-Gigabit SFP+
fiber port on the device. An SFP+ cable is suitable for short connections.
b.
If the local port can go up, replace the peer port with a new one to verify that the peer port is
operating correctly.
c.
If the local port cannot go up, replace the local port with a new one to verify that the local port
is operating correctly.
4.
Verify that the transceiver module is operating correctly:
a.
Execute the display transceiver alarm interface command to examine the alarms present on the
transceiver module.

b.
Use an optical power meter to verify that the Tx power and Rx power of the transceiver module
are stable and are within the correct range.
c.
Execute the display transceiver interface command to verify that the wavelength and
transmission distance of the local transceiver module are consistent with the wavelength and
transmission distance of the peer transceiver module.

d.
If the transceiver module is not operating correctly, replace it with a new H3C transceiver
module that matches the fiber port.
For more information about transceiver modules, see related installation guides.
The device displays None if no error occurs.
The device displays alarms if the transceiver module fails or the type of the transceiver
module does not match the port type.
