GLOSSARY

automatic recovery An upgrade method that copies the primary boot source to the NMS, then copies the upgraded software back to the bridge/router as the test boot source. After a successful test boot, the upgraded software is designated as the primary boot source while the original software still present on the flash memory, is designated the secondary boot source. If the upgrade fails, the bridge/router automatically reboots from the original software. Automatic recovery requires enough flash memory to hold two software sets.

backup Copying the software, including the images and configuration files, from the bridge/router to the NMS using Upgrade Link or the bcmbackup utility.

backup location See default directory structure.

baseline A copy of the bridge/router configuration files stored in a directory on the network management station. Baselining establishes a known good configuration set by checking for consistency between similar configuration files on the network management station and the NETBuilder bridge/router. Baselining assumes that the versions of software and firmware running on the NETBuilder system have not changed since the baseline was established.

BCM Boot Change Management. Individual command-line utilities and scripts that use SNMP to perform EEPROM boot block and file manipulation operations on the NETBuilder bridge/router and between the NETBuilder bridge/router and Network Management Stations. This includes file transfer using TFTP.

bcm utilities See NETBuilder Upgrade Management Utilities.

bcmupdate An upgrade management utility that is used to upgrade configuration files on a network management station.

boot image A software file that is loaded into DRAM and executed by a bridge/router. The main boot image files are named boot.29k and boot.68k.

BOOTP Bootstrap Protocol. Allows a bridge/router to obtain its IP address dynamically from a network management station instead of from local EEPROM.

boot source A reference to a directory on the bridge/router where the boot and configuration files are stored. You can set and view boot source information using the bcmconfig utility or the Sysconf command.

CCS Compact Configuration Storage. An ASN.1-based file format used to store bridge/router configuration information.

configuration files Files on the bridge/router that store parameter values and settings you have set in the software.
