18CHAPTER 3: PLANNING AND PREPARING THE UPGRADE

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>

If no 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 bridge/router running software version 11.0 or lower, the FTP password is overwritten with the following text string:

Choosing Automatic If you have enough flash memory for dual-image support, complete your upgrade

Recovery or Manual using automatic recovery. If you have only enough memory for single-image

Recoverysupport, complete the upgrade using manual recovery. The following sections describe the difference between automatic and manual recovery and the memory requirements for each platform.

Automatic Recovery The default upgrade procedure uses automatic recovery. After backing up the current software to the network management station (NMS), the new software is copied into a test directory while the current software remains in the primary directory. If you accept the upgrade after booting from the test directory, the new software becomes the primary boot source, and the old software becomes the secondary boot source.

If you are upgrading your hardware as well as the software, the procedure for automatic recovery saves the software package that was originally on the new hardware as the secondary boot source.
