‹ Firmware Revision – nciDevMajVer, nciDevMinVer
These two configuration properties are used to identify the major and minor versions of the interface firmware.
The major version number is incremented when the network interface for the device changes. Major revisions require an upgrade of both the
external interface file (.xif) and application image file (.nxe). The new external interface file re-defines the network interface to any network
management tools in use. The new application image file is downloaded to an installed device to upgrade it’s functionality and network interface
definition.
The minor version number is incremented for changes which affect device functionality but do not affect the device’s network interface. Minor
revisions require an upgrade of the application image file (.nxe) only. The new application image file is downloaded to an installed device to
upgrade it’s functionality and network interface definition.
