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 module or logical interface is removed.
If you repeatedly insert and remove different subcards or interface modules 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:
