3.2.4 Clearing the 16-bit Interface Indexes Not Used in the Current System

In practical networks, the network management software requires the device to provide
a uniform, stable 16-bit interface index. That is, a one-to-one relationship should be
kept between the interface name and the interface index in the same device.
For the purpose of the stability of an interface index, the system will save the 16-bit
interface index when a card or logical interface is removed.
If you repeatedly insert and remove different subcards or interface cards to create or
delete a large amount of logical interface, the interface indexes will be used up, which
will result in interface creation failures. To avoid such a case, you can clear all 16-bit
interface indexes saved but not used in the current system in user view.
After the above operation,
For a re-created interface, the new interface index may not be consistent with the
original one.
For existing interfaces, their interface indexes remain unchanged.
Follow the step below to clear the 16-bit interface indexes not used in the current
system:

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.

3.2.5 Identifying and Diagnosing Pluggable Transceivers

I. Introduction to pluggable transceivers
At present, four types of pluggable transceivers are commonly used, and they can be
divided into optical transceivers and electrical transceivers based on transmission
media as shown in
