Upgrading the Boot File Through Command Lines
Follow the steps to upgrade the boot file:
1) Save the boot file to the root directory of the AP's storage medium using FTP, TFTP, or other
approaches.
2) Use a command to specify the boot file for the next boot of the AP.
3) Reboot the AP to make the boot file take effect.
When multiple Boot ROM files are available on the storage media, you can specify a file for the next
device boot by executing the following command. A main boot file is used to boot a device and a backup
boot file is used to boot a device only when a main boot file is unavailable.
Follow the step below to upgrade the boot file:

You must save the file for the next device boot under the root directory of the AP. You can copy or move
a file to change the path of it to the root directory.
Clearing the 16-Bit Interface Indexes Not Used in the Current
System
In practical networks, the network management software requires the AP 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
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 16-bit interface indexes saved but not used in the
current system in user view.
After the above operation,
z For a re-created interface, the new interface index may not be consistent with the original one.
z 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:
