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
logical interface is removed.
If you repeatedly 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, clear all 16-bit interface indexes
saved but not used in the current system 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 16-bit interface indexes not used in the current system:

Disabling password recovery capability
Password recovery capability controls console user access to the device configuration and SDRAM from
BootROM menus.
If password recovery capability is enabled, a console user can access the device configuration without
authentication and reconfigure the console login password and user privilege level passwords.
If password recovery capability is disabled, a console user must restore the factory-default configuration
before configuring new passwords. Restoring the factory-default configuration deletes the next-startup
configuration files.
Availability of related BootROM options varies with the password recovery capability setting. For more
information, see the release notes.
To enhance system security, disable password recovery capability.
