Disabling sending removal interrupt signals before
switching fabric module removal
By default, a switching fabric module sends removal interrupt signals before it is removed so that the
device can switch the traffic to another switching fabric module, ensuring uninterrupted traffic.
If the switching fabric module frequently sends incorrect removal interrupt signals before it is removed, the
device might fail. To avoid this situation, configure the switch-fabric removal-signal-suppression
command.
To disable the switching fabric module from sending removal interrupt signals before it is removed:

By default, a switching fabric
module sends removal interrupt
signals before it is removed.
Verifying and diagnosing transceiver modules
Verifying transceiver modules
You can use one of the following methods to verify the genuineness of a transceiver module:
• Display the key parameters of a transceiver module, including its transceiver type, connector type,
central wavelength of the transmit laser, transfer distance, and vendor name.
• Display its electronic label. The electronic label is a profile of the transceiver module and contains
the permanent configuration, including the serial number, manufacturing date, and vendor name.
The data is written to the storage component during debugging or testing.
The electrical label information depends on the transceiver module model.
To verify transceiver modules, execute the following commands in any view:
Task Command Remarks
Display the key
parameters of
transceiver modules.
display transceiver interface
[ interface-type interface-number ]
N/A
Display the electrical
label information of
transceiver modules.
display transceiver manuinfo interface
[ interface-type interface-number ]
This command cannot display
information for some transceiver
modules.
Diagnosing transceiver modules
The device provides the alarm and digital diagnosis functions for transceiver modules. When a
transceiver module fails or is not operating correctly, you can do the following:
