Solution
To resolve the issue:
1.
Verify that the transceiver module and fiber of the local port match the transceiver module and
fiber of the peer port.
2.
Identify whether the fiber combo ports are activated on the Combo ports. If not, enter the
physical interface views and execute the
combo enable fiber
command. Make sure the
ports are connected with optical fibers.
3.
Remove and install the transceiver modules again and again to trigger the device to identify the
transceiver modules. Make sure the transceiver modules are compatible with the devices.
4.
If the issue persists, use the
display diagnostic-information
command to save the
operating statistics for multiple feature modules.
5.
If the issue persists, contact H3C Support.
