36CHAPTER 5: UPGRADING A BRIDGE/ROUTER USING THE COMMAND-LINE UTILITIES

Minimal disk storage requirements depend on the number of different software versions that are stored on the disk drive. Calculate:

■6 MB for each version of the NETBuilder II bridge/router image

■6 MB for each version of the PathBuilder S5xx switch image

■4 MB for each version of the SuperStack II, SuperStack II SI, or OfficeConnect bridge/router image

While you must purchase one copy of software for each bridge/router or switch, you only need to install one copy of a version of software on the NMS.

Setting Up a File	You can choose to transfer files using FTP or TFTP.
Transfer Method	Setting up for TFTP File Transfers
	To use TFTP, you need to set up your NMS in preparation for TFTP file transfers.
	Make sure your TFTP server is running. On a Windows workstation 3Com’s
	3CServer is shipped along with the utilities. Upgrade Link launches 3CServer
	during start up.
	Specify the -tftp flag in all command line utilities which use file transfers
	(bcmsysupgrade, bcmbackup, bcmrestore) if you want to use TFTP file transfer. For
	example, to specify TFTP file transfer use:
	bcmsysupgrade -s:from_nb -tftp <device>
	If neither flag is used, TFTP is used by default for software release 11.0 and lower,
	but FTP is used by default for software release 11.1 and higher. If the -ftp flag is
	specified on a NETBuilder bridge/router running software version 11.0 or lower,
	the FTP password is overwritten with the following text string:
	****
	Setting up for FTP File Transfers
	To use FTP, you need to set up your NMS in preparation for FTP file transfers.
	For Upgrade Link, the user name and password is specified in the Setting Page, as
	shown on page 23.

On a UNIX NMS, follow these steps:

1Create a user on your system with /tftpboot as the home directory.

2When using the upgrade utilities via the command line or the Transcend Upgrade Manager, specify this user name and password in the BCMFTPUSER and BCMFTPPASS environment variables.

Specify the -ftp flag in all command line utilities that use file transfers (bcmsysupgrade, bcmbackup, bcmrestore) if you want to use FTP file transfer. For example, to specify FTP file transfer use:

bcmsysupgrade -s:from_nb -ftp <device>
