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.

ENTERPRISE OS 11.3 specifications

3Com Enterprise OS 11.3 is a robust network operating system designed specifically for enterprise-level applications, offering a comprehensive suite of features and technologies that enhance network performance, reliability, and security.
