You can use the
Vendor Name
field in the prompt information of the
display transceiver
command to identify an anti-spoofing pluggable transceiver customized by H3C. If the field is
H3C
,
it is considered an H3C-customized pluggable transceiver.

Electrical label information is also called permanent configuration data or archive information,
which is written to the storage component of a board during device debugging or testing. The
information includes name of the board, device serial number, and vendor name or name of the
vendor who customizes the transceiver.
Diagnosing pluggable transceivers
The system outputs alarm information for you to diagnose and troubleshoot faults of pluggable
transceivers. Optical transceivers customized by H3C also support the digital diagnosis function, which
monitors the key parameters of a transceiver, such as temperature, voltage, laser bias current, TX
power, and RX power. When these parameters are abnormal, you can take corresponding measures to
prevent transceiver faults.
Follow these steps to diagnose pluggable transceivers:
