Getting Help

Help is available in HTML or (UNIX) man pages.

Man Pages On a UNIX system, access the man pages by entering:

man bcm-intro

To access the man pages for a specific utility, use:

man <NMU_name>

where <NMU_name> is the name of the upgrade utility.

HTML Help To access the HTML help, enter the following URL in your browser:

/usr/3Com/bcm/gui/hlp/bcm-intro.html

Or to access help for a specific utility, use:

/usr/3Com/bcm/gui/hlp/<utility>.html

bcmbackup

Syntax bcmbackup [both primary secondary] <-ftp -tftp> [-name: <backname>]

<device>

Description You can use this utility to prepare a network management station as a secondary boot source, to archive the configuration as a backup copy, to obtain a baseline configuration, or to perform an off-line configuration. The bcmbackup utility copies the primary and secondary boot sources from a bridge/router or switch to a network management station. The bcmbackup utility can be used instead of the -s:from_nb stage of bcmsysupgrade, which captures only the primary boot source.

You can assign names to the backup directories, which allows you to maintain multiple backups of the primary and secondary boot blocks. This symbolic name is applicable to both the primary and secondary boot blocks. The default boot block names are supported to maintain backward compatibility.
