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.
−
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.
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.
[H3C] display transceiver interface Ten-GigabitEthernet 1/0/15
Ten-GigabitEthernet1/0/15 transceiver information:
Transceiver Type : 1000_BASE_SX_SFP
Connector Type : LC
Wavelength(nm) : 850
Transfer Distance(m) : 550(50um),270(62.5um)
Digital Diagnostic Monitoring : YES
Vendor Name : H3C

d.
If the transceiver module is not operating correctly, replace it with a new H3C transceiver
module that matches the fiber port.
