Clearing unused 16-bit interface indexes
The device must maintain persistent 16-bit interface indexes and keep one interface index match one
interface name for network management. After deleting a logical interface, the device retains its 16-bit
interface index so the same index can be assigned to the interface at interface re-creation.
To avoid index depletion causing interface creation failures, you can clear all 16-bit indexes that have
been assigned but not in use. The operation does not affect the interface indexes of the interfaces that
have been created but the indexes assigned to re-recreated interfaces might change.
Follow the step below to clear unused 16-bit interface indexes:
To do…
Use the command…
Remarks
Clear unused 16-bit interface
indexes
reset unused porttag
Required
Available in user view.
CAUTION:
•
In an IRF fabric, the command applies to all member switches.
•
A confirmation is required when you execute this command. The command will not run if you fail to
make a confirmation within 30 seconds or enter
N
to cancel the operation.
Verifying and diagnosing transceiver modules
NOTE:
Support for the pluggable transceivers and the transceiver type depends on the device model.
Verifying transceiver modules
You can verify the genuineness of a transceiver module in the following ways:
•
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.
Perform the following commands in any view to verify transceiver modules:
To do…
Use the command…
