2.
Execute the
display transceiver information interface
command in probe view to verify that
the transceiver modules at the two ends are the same type, and the transceiver module is
compatible with the interface.
3.
Verify that the fiber type is compatible with the transceiver module.
4.
Execute the
display hardware internal module
interface-type interface-number
reg 0
command to view the CPLD. Determine whether a transmit or receive failure or a hardware
failure has occurred.
5.
If the problem persists, contact H3C Support.
Transceiver module type not recognized
Symptom
The system generates a message that reports unknown transceiver module type.
Solution
To resolve the problem:
1.
Execute the
display hardware internal module
interface-type interface-number
reg 0
command in probe view to verify that the transceiver module is not a counterfeit and has an
electronic label.
If the transceiver module is a counterfeit, the transceiver module type fails to be displayed
correctly and the
display transceiver manuinfo interface
and
display transceiver
diagnosis interface
commands are not available.
2.
Execute the
display hardware internal transceiver register interface
command in probe
view to verify that the system can read the values on the registers in the transceiver module.
3.
If the problem persists, contact H3C Support.
Interface or transceiver module alarm
Symptom
An interface alarm is generated, or messages that report transceiver module insertion and removal
are output repeatedly.
Solution
To resolve the problem:
1.
Verify that the CPLD version of the interface module is updated to the most recent version.
2.
Execute the
display transceiver alarm interface
command to determine whether an alarm
was generated and whether the alarm is consistent with the output messages.
3.
If the problem persists, contact H3C Support.
