3Com ENTERPRISE OS 11.3 PLANNING AND PREPARING THE 3 UPGRADE, Setting Up a File, Transfer Method

PLANNING AND PREPARING THE

3 UPGRADE

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	You can choose to transfer files using FTP or TFTP.
Transfer Method

Setting up for TFTP File To use TFTP, you need to set up your NMS in preparation for TFTP file transfers.

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 To use FTP, you need to set up your NMS in preparation for FTP file transfers.

Transfers

For Upgrade Link, the user name and password is specified in the Setting Page, as shown on page 23.
