OVERVIEW

This chapter provides an overview of the upgrade tools, process, and support limitations.

Upgrade Tools and Process

Definition of network
management station
The upgrade procedures in this guide use the Enterprise OS Upgrade Management Utilities on a UNIX or Windows network management station (NMS).
An NMS is a UNIX or Windows system that has a TFTP/FTP server running in addition to software, such as the Enterprise OS Upgrade Management Utilities, to manage your network. For Windows, the utilities include the 3Com server.
If you are upgrading multiple bridge/routers, you can install and use the Network Admin Tools utilities in the Transcend Control Services, available separately. See the Transcend user guide for more information.
You can use the NETBuilder Upgrade Link application that comes with the utilities provides an easy to use graphical user interface (GUI) to upgrade one or more bridge/routers. Or you can access the utilities directly using the command-line.
When upgrading multiple bridge/routers simultaneously using command line utilities, the topology of the network should be considered and the bridge/routers should be upgraded in a sequence that will not disrupt the network.
If you are performing an image-only upgrade, you can use the utilities or applications, or you can copy the software manually using the Enterprise OS user interface.
®
Enterprise Manager or Transcend Network
®
TFTP/FTP
The utilities are shipped with your software package on a CD-ROM and must be installed on an NMS on the same network as the bridge/router. You can also download the utilities from the 3Com web, FTP, or BBS sites.
The utilities run on the following operating systems:
Solaris 2.x
HP-UX 10.x
IBM AIX 4.x or later
Windows NT 4.x
Windows 95/98

How the Utilities Work The software on your bridge/router or switch consists of a bootable image file and

configuration files that store all your settings. The Enterprise OS Upgrade Management Utilities update all your software files after copying them to a UNIX or Windows NMS. Because the upgrade occurs on a copy of the files on the NMS, the bridge/router remains operational during the upgrade. The utilities then copy the new image and updated files back to the bridge/router.
Primary, Secondary, and Test Boot Sources
The NETBuilder bridge/router or PathBuilder switch boots from a default directory, called the primary boot source, which can be set using the SysconF command in the Enterprise OS user interface. If you have more than one set of boot images, you can specify a backup directory, called the secondary boot source. There is also a test boot source, which the utilities use to test a new upgrade before making it the primary boot source. Because the boot sources are only pointers to particular directories, the utilities can dynamically change the boot sources without having to move any files.
Automatic or Manual Recovery
If your switch or bridge/router has enough flash memory, you can have both sets of software: the old version and the new version. After a successful test boot with the new software, the primary boot source is changed to the new version. If the test boot is not successful, the system automatically reboots with the old version. Dual-image support is described in the procedures for automatic recovery.
If you have only enough flash memory for the new version, you can still recover the old version from the NMS using the utilities. Single-image support is described in the procedures for manual recovery.
For memory requirements for automatic or manual recovery, see Chapter 3.
Rules and Support Limitations 11

Rules and Support Limitations

Before planning your upgrade, refer to the following rules and support limitations:
The utilities do not support Remote Boot and Configuration Services (RBCS) or
network booting.
Upgrades from NETBuilder bridge/routers running version 7.x, or earlier, are not
supported.
You cannot upgrade to a different platform. For example, you can only
upgrade an OfficeConnect You cannot upgrade a SuperStack
®
bridge/router to an OfficeConnect bridge/router.
®
II NETBuilder bridge/router to a SuperStack II NETBuilder SI bridge/router. The only exception is an upgrade from a NETBuilder II
®
CEC module to a DPE module.

Take Time to Plan Because networks today have become increasingly complex, upgrading your

network requires a systematic approach. 3Com recommends that you plan your upgrade carefully before implementing it. See Chapter 3 to plan your upgrade.
12 CHAPTER 1: OVERVIEW
INSTALLING THE UTILITIES ON A
2
N
ETWORK MANAGEMENT STATION
Before you start the upgrade process, you must install the Enterprise OS Upgrade Management Utilities on a network management station (NMS). If you are using Transcend Enterprise Manager or Transcend Network Control Services, which has the utilities bundled, you should install the latest utilities to take advantage of new features and version support.
This chapter describes how to install the Enterprise OS Upgrade Management Utilities on the following platforms:
Solaris 2.x
HP-UX 10.x
IBM AIX 4.x or later
Windows NT 4.x
Windows 95/98

Installing the Utilities on a Windows System

You can install the utilities from a CD-ROM or from utilities that you have downloaded to your hard disk. To install the utilities on a Windows system, follow these steps:
1 If you have installed utilities before or have Transcend, check the version by
entering:
bcmdiagnose
If the version is earlier than 11.3, continue to the next step. If you already have
11.3, you do not need to reinstall the utilities.
2 Change to the utilities directory.
If you are using the CD-ROM:
a Insert the CD-ROM into the CD-ROM drive. b Open a command window. c Change to the CD-ROM directory.
For example, if E is the drive letter for the CD-ROM, enter:
E:
3 If you download the utilities to your hard disk (see Chapter 8 for information
about downloading the utilities):
a Decompress the utilities. b Open a command window. c Change to the utilities directory using:
<drive>:\<path>\
14 CHAPTER 2: INSTALLING THE UTILITIES ON A NETWORK MANAGEMENT STATION
4 Run the setup program for Windows:
To install all packages, including the utilities and package definitions for use
with Transcend if required, use:
bcmsetup <drive>: all
Where <drive> is the drive you want to install the utilities on.
The packages install in the default directory \usr\3Com\bcm\, and the following paths are added to the autoexec.bat file:
<drive>:\usr\3com\bcm\bin\ <drive>:\usr\3com\common\bin\
5 Reboot your system to use the path, which is required for all utility commands. Or,
if you do not want to reboot, you can enter the path manually at the command prompt:
<drive>:\usr\3com\common\data\profile
6 Use the bcmdiagnose utility to ensure that your installation is correct by entering:
bcmdiagnose

Installing the Utilities on a UNIX System

Preparing for the
Installation

Procedure To install the utilities on a UNIX system, follow these steps:

You can install the utilities from a CD-ROM or from utilities that you have downloaded to your hard disk.
Before installing the utilities, verify the following items:
Your NMS is running one of the supported operating systems.
Check the operating system you are running by entering:
uname -a
The version message may refer to Solaris 2.5 as SunOS 5.5.
You need to upgrade utilities you have already installed. The utilities come
bundled with Transcend. To check the version, enter:
bcmdiagnose
Your root password on the NMS (UNIX only).
Your NMS is running a TFTP/FTP server.
1 Log on as root. 2 Change to the utilities directory.
If you are using the CD-ROM:
a Mount the CD-ROM.
For more information on mounting instructions for each supported UNIX operating system, see Appendix C.
b Change to the appropriate directory on the CD-ROM for your operating system
using:
cd /<cd-rom path>/<os>
Where <os> is the directory for your operating system:
Installing the Utilities on a UNIX System 15
Table 1 UNIX Directories
Operating System Directory Name
Solaris 2.5.x sunos5 HP-UX 10.x HP_UX IBM AIX 4.1.x, 4.2x aix
If you download the utilities to your hard disk (see Chapter 8 for information
about downloading the utilities):
a Decompress the utilities. b Change to the utilities directory on your hard disk using:
cd /<path>/
3 Run the setup program.
To install all packages from the CD-ROM, including the utilities and package
definitions for use with Transcend, enter:
./bcmsetup all
To install only the upgrade utilities, enter:
./bcmsetup bcm
The utilities are installed in the default directory /usr/3Com/bcm/. If you are working in an HP-UX operating system, the bcmsetup command must
be uppercase, that is, BCMSETUP. The options that follow remain lowercase.
4 Complete the following step for your UNIX shell:
For a C-shell installation, add the contents of the following file to the .cshrc file
for each user you want to have access to the utilities, including root: /usr/3Com/common/data/.login-bcm Or you can enter the path after every logon:
source /usr/3Com/common/data/.login-bcm
For a Bourne shell installation, add the contents of the following file to the
.profile file for each user you want to have access to the utilities, including root: /usr/3Com/common/data/.profile-bcm Or you can enter the path after every logon:
. /usr/3Com/common/data/.profile-bcm
5 Return to normal privilege by entering:
exit
6 Use the bcmdiagnose utility to ensure that your installation is correct by entering:
bcmdiagnose
16 CHAPTER 2: INSTALLING THE UTILITIES ON A NETWORK MANAGEMENT STATION
Setting up for Auto
Startup
On a UNIX NMS, after you have completed the previous setup procedures you need to set up the BootP server.
To set up the BootP server, enter:
bcmsteup -bootp
This command does not need to be used when you are operating on a Windows 95/98/NT-based NMS.
PLANNING AND PREPARING THE
3
Setting Up a File Transfer Method
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 pr ovides 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.
You can choose to transfer files using FTP or TFTP.
Setting up for TFTP File
Transfers
Setting up for FTP 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:
****
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.
18 CHAPTER 3: PLANNING AND PREPARING THE UPGRADE
On a UNIX NMS, follow these steps:
1 Create a user on your system with /tftpboot as the home directory. 2 When 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:
****
On a Windows NMS, follow these steps:
1 Create a user in 3Com’s 3CServer FTP settings. 2 When 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:
****
Choosing Automatic Recovery or Manual Recovery
If you have enough flash memory for dual-image support, complete your upgrade using automatic recovery. If you have only enough memory for single-image support, 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.
19

Manual Recovery An upgrade with manual recovery (using the -m option with the bcmsysupgrade

utility) formats the flash memory after backing up the current software, then copies the upgraded files to the bridge/router. If the upgrade is not successful, you must restore the software from the NMS.
If you are upgrading your hardware as well as the softwar e, you can easily r ecover your old hardware if the upgrade is not successful. However, because you erased the flash memory on the new hardware, you will need to restore the original software from the NMS if you want to return the new hardware to its original state.
Table 2 lists the memory requirements for each software package on the platform you are upgrading to. If you are upgrading to an earlier version of software, see the guides that came with that version for the memory requirements.

Checking DRAM To check how much DRAM you have installed on the switch or bridge/router, on

the NMS use:
bcmuname -M <device>
Where <device> is the IP address or hostname of the switch or bridge/router.

Checking Flash Memory To check how much flash memory you have installed on the switch or

bridge/router, on the NMS use:
bcmdf <device>[:<drive:>]
Where <device> is the hostname or the IP address of the switch or bridge/router. Specify drive A for NETBuilder II bridge/routers or PathBuilder switches. Do not specify a drive for SuperStack II or OfficeConnect bridge/routers.
Checking the Software Version 21

Checking the Software Version

To display the current software version and package you are running, use the bcmuname utility on the NMS:
bcmuname -R <device>
Where <device> is the IP address or hostname of the bridge/router. To display the current software version and package using the Enterprise OS user
interface, enter:
SHow -SYS VERSion

UPGRADING USING THE NETBUILDER

Preparing for the Upgrade
U
PGRADE LINK APPLICATION
This chapter describes how to upgrade the software on a NETBuilder bridge/router or a PathBuilder switch using the Upgrade Link application. Upgrade Link is an easy to use GUI for the upgrade utilities that runs in a web server. Access to the server is available via a web browser. If you are upgrading multiple bridge/routers, you should use Transcend Enterprise Manager or Transcend Network Control Services instead. Contact your network supplier for more information about Transcend. Or if you want to write scripts, you can use the command-line utilities as described in Chapter 5. Use the command-line utilities if you do not have a web browser on your network management station (NMS).
An NMS is a UNIX or Windows system that has a FTP/TFTP server running in addition to software, such as the Upgrade Management Utilities, to manage your network. For Windows, the utilities include the 3Com FTP/TFTP server called 3CServer.
Before upgrading your system, confirm the following items:
You have installed the utilities according to Chapter 2.
You have set the path for the utilities (UNIX only). If you have not set the path,
complete the following step for your UNIX shell:
For a C-shell installation, add the contents of the following file to the .cshr c
file for each user you want to have access to the utilities, including root: /usr/3Com/common/data/.login-bcm Or you can enter the path after every logon:
source /usr/3Com/common/data/.login-bcm
For a Bourne shell installation, add the contents of the following file to the
.profile file for each user you want to have access to the utilities, including root:
/usr/3Com/common/data/.profile-bcm Or you can enter the path after every logon:
. /usr/3Com/common/data/.profile-bcm
All configuration files are in the same directory as the boot image.
You have booted your bridge/router from the primary boot source.
You have a web browser installed with Java support, such as Netscape
Navigator 4.5 or Internet Explorer 4.x, and you have it in your path (UNIX).
CAUTION: Only one client at a time should access the Upgrade Link Server.
There is sufficient disk space on the NMS for the amount of software you are
installing.
26 CHAPTER 4: UPGRADING USING THE NETBUILDER UPGRADE LINK APPLICATION
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 or PathBuilder
switch image
4 MB for each version of the SuperStack II, SuperStack II SI, or
OfficeConnect NETBuilder bridge/router image
While you must purchase one copy of software for each device, you only need to install one copy of a version of software on the NMS.
Running Upgrade Link Locally
Upgrade Link contains its own web server. Client access to the web server is available locally or remotely via a web browser. Running the Upgrade Link application locally means that the web browser and the web server are running on the same NMS.
To run Upgrade Link locally on a UNIX NMS, use:
UpgradeLink [-NoAuthentication] [-NoSecurity]
This command starts the NETBuilder Upgrade Server and the default browser. Two command options are available.
When NoAuthentication is specified, Upgrade Link will allow a remote client to
access the server without user authentication, see “Settings Page” for a description of the available settings.
When you specify NoSecurity, Upgrade Link starts and will accept connections
from all IP addresses. Otherwise, only those client IP addresses listed in the /usr/3Com/common/data/allow file will be accepted by Upgrade Link.
For security, an administrator can enter the IP addresses of only those clients who will be allowed to upgrade devices. An allow file is an ASCII text file containing the IP addresses of clients to upgrade devices. The allow file looks like the following:
129.213.100.151
129.213.100.152
139.87.172.100
Running Upgrade Link Remotely
To run Upgrade Link locally on a Windows NMS, click the Start menu, then choose Programs
Remote Upgrade Utilities⇒Upgrade Link.
Your default browser is launched. On Windows, the 3Com FTP/TFTP server is also launched.
When you exit Upgrade Link, you will also exit the browser and, for Windows, the FTP/TFTP server.
You can access the NETBuilder Upgrade Server remotely using a browser.
Start the NETBuilder Upgrade Server on the NMS using:
bcmnbrus <port> [-NoSecurity | -NoAuthentication]
Status and Settings Pages 27
where port is the TCP socket on which the client can communicate with the server. On UNIX systems, you can add this command to cron. On Windows 95/98/NT systems, this command can be run as a console application.
When NoSecurity is specified, the bcmnbrus command allows connections from all IP addresses. Otherwise, only those client IP addresses listed in the/usr/3Com/common/data/allow file will be accepted by Upgrade Link.
For security, an administrator can enter the IP addresses of only those clients who will be allowed to upgrade devices. An allow file is an ASCII text file containing the IP addresses of clients to upgrade devices. The allowed file looks like the following:
129.213.100.151
129.213.100.152
139.87.172.100
When NoAuthentication is specified, the bcmnbrus command allows the remote client to access the server without user authentication, see “Settings Page” on page 28 for a description of the available settings.
Then, to access Upgrade Link from a web browser, enter the following URL:

Status and Settings Pages

http://<server_nam>:<port>/
Do not resize the browser window while the Upgrade Link application is running. CAUTION: Only one client at a time should access the Upgrade Link Server.
After each procedure described in this section, the Status or Settings page appears. Table 3 describes the buttons on the bottom of the Status page.

You can choose the method of file transfers. TFTP is used by default for
NETBuilder bridge/router software release 11.0 and lower while FTP is used by default for NETBuilder bridge/router software release 11.1 and higher and Enterprise OS version 11.3.
Enter an SNMP read/write string and the NETBuilder bridge/router or
PathBuilder switch user name and password.
If -noAuthentication was not specified in Upgrade Link or on the bcmnbrus
command line, authentication will be used and you must enter the NETBuilder or PathBuilder username and password.
If -noAuthentication was specified in Upgrade Link or on the bcmnbrus
command line, no authentication is required and any user name and password entries are ignored.
If using FTP, enter the FTP client user name and password.
Verifying for Upgrading 29

Verifying for Upgrading

Before upgrading, run the diagnostic utility in Upgrade Link to verify connectivity to the switch or bridge/router by following these steps:
1 Choose a switch or bridge/router from the pop-up list in the Console page, or click
New to enter the IP address or hostname. The pop-up list contains devices that you have upgraded or backed-up before.
2 Select Verify Upgrade Services (Diagnose) and click Apply.
The Settings Page appears. Select the appropriate settings as described in on “Settings Page” on page 28 and click OK to close that window.

Installing Software on the NMS

The Status page appears showing the results of the diagnostic tests.
3 If the Status page shows a failure, check the SNMP read/write community string
and FTP/TFTP server settings. If the Status page shows a success, click Home to continue with the upgrade and
return to the Console page.
Upgrade Link installs the software on the NMS in the following directory: Windows:
\%tftpboot%\image\<platform>\SW|FW\<version>\<pkg>
UNIX:
/tftpboot/image/<platform>/SW|FW/<version>/<pkg>
For UNIX, if there is not enough space on the disk, you can link /tftpboot to another disk. For example, to link /tftpboot to the usr directory, enter:
ln -s /usr/tftpboot /tftpboot/
The utilities work only with the default directory names and structures.
