If you repeatedly insert and remove different subcards or interface cards to create or delete a large
number of logical interfaces, the interface indexes will be used up, which will result in interface creation
failures. To avoid such a case, you can clear all unused16-bit interface indexes in user view.
After the preceding operation,
• For a re-created interface, the new interface index might not be consistent with the original one.
• For existing interfaces, their interface indexes remain unchanged.
Follow these steps to clear the unused16-bit interface indexes:
To do… Use the command…

Available in user view.
CAUTION:
A
confirmation is required when you execute this command. If you fail to make a confirmation within 30
seconds or enter N to cancel the operation, the command will not be executed.
Identifying and diagnosing pluggable transceivers
Introduction to pluggable transceivers
Table 10 lists of the commonly used pluggable transceivers. They can be further divided into optical
transceivers and electrical transceivers based on transmission medium.

Identifying pluggable transceivers
Because pluggable transceivers are of various types and from different vendors, you can use the
following commands to view the key parameters of the pluggable transceivers, including transceiver type,
