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:

****

On a Windows NMS, follow these steps:

1Create a user in 3Com’s 3CServer FTP settings.

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

You can specify the -ftp flag in the utilities (bcmsysupgrade, bcmbackup, bcmrestore) if you want to use FTP file transfer.

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:

Prediagnosing System Before you begin your upgrade, 3Com recommends that you run the

Problemsbcmdiagnose utility specifying the file transfer utility, FTP, or TFTP and the IP address or hostname of the bridge/router you are upgrading.

Before using the bcmdiagnose utility, you should set the BCMFTPUSER and BCMFTPPASS environment variables. When using FTP, an error message is generated and the file transfer is aborted if these variables are not set.

The bcmdiagnose utility helps detect any problems with SNMP, FTP or TFTP connectivity.

To run the bcmdiagnose utility on your NMS, use:

bcmdiagnose [ -ftp -tftp ] [<device> -h]

Where <device> is the IP address or hostname of the bridge/router you are upgrading. The -ftp and -tftp flags force the specified file transfer types. See Appendix A for more information about any error messages that may appear.

Installing the

To install the NETBuilder software, follow these steps:

Software on the NMS

 

1For UNIX, login as root.

2If you are using a CD-ROM, insert the CD-ROM into the CD-ROM drive on the NMS.

aMount the CD-ROM (UNIX only).

See Appendix C for information on how to mount the CD-ROM.

3Make sure you are using version 11.3 of the Enterprise OS Upgrade Management Utilities.
