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-GE SFP+ cable to directly connect the local port and another 10-GE SFP+ of the
same interface module. A 10-GE SFP+ cable is suitable for short connections.
b.
If the local port can come up, replace the peer port with a new one to verify that the peer port
is operating correctly.
c.
If the local port cannot come 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.
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.
5.
Verify that the fiber matches the transceiver module. If they do not match, replace the fiber with
a new one that matches the transceiver module.
6.
If the issue persists, contact H3C Support.
