PLANNING AND PREPARING THE
U
PGRADE
This chapter describes setting up a file transfer method, choosing automatic or
manual recovery, checking the required memory for each package, including
instructions for checking the memory, and provides planning tables to copy and fill
out for each bridge/router.
If you are upgrading multiple bridge/routers using Transcend Enterprise Manager
or Transcend Network Control Services, or are using the command-line utilities,
you should make sure each bridge/router has enough flash memory and DRAM for
the software package you have chosen. The Upgrade Link application
automatically checks the memory of the bridge/router.
For a list of all software packages and the recommended upgrade path for your
version, see Appendix B.
Setting Up a File
Transfer Method
You can choose to transfer files using FTP or TFTP.
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 bridge/router running software version 11.0 or lower, the FTP
password is overwritten with the following text string:
****
Setting up for FTP File

shown on page 23.
