Utilities

 

Installing the NETBuilder

You can upgrade from a CD-ROM, a tar file, or an image you have downloaded

Software

from 3Com. If you are installing the software from a CD-ROM, complete the

 

procedure in “Installing the Software on the NMS” on page 37.

 

You can choose to transfer files using FTP or TFTP. Complete the procedure in

 

“Setting Up a File Transfer Method” on page 17.

Prediagnosing System

Detect any problems with SNMP or FTP/TFTP connectivity using:

Problems

bcmdiagnose <device>

 

 

Where <device> is the IP address or hostname of the bridge/router you are

 

diagnosing.

Upgrading Using

To perform an image-only upgrade using automatic recovery, follow these steps.

Automatic Recovery

See Chapter 3 for the memory requirements for automatic recovery.

 

Whenever you specify an option with bcmsysupgrade, you must repeat that

 

option for all steps in the procedure.

1Back up your current software to the NMS using:

bcmsysupgrade [-options] -s:from_nb -I -V:<software version> <device>

where [-options] lets you specify the EncryptionLicenseRead option that indicates you have read and understand the encryption license agreement notice and <device> is the IP address or hostname of the bridge/router or switch you are upgrading.

CAUTION: When upgrading to a package containing encryption, you must specify the -EncyrptionLicenseRead option flag. If you attempt to upgrade to an encrypted package and you have not specified the -EncryptionLicenseRead option, the upgrade will fail.

2Copy the configuration files into the new software directory on the NMS using:

bcmsysupgrade -s:update -I -V:<software version> <device>

3Copy the upgraded software to the bridge/router using:

bcmsysupgrade -s:to_nb -I -V:<software version> <device>

4Test your new software using:

bcmsysupgrade -s:test_boot -I -V:<software version> <device>

The bridge/router is rebooted, and the utilities confirm IP connectivity and that the expected version of software is running.

5Verify that your upgrade completed successfully.

To verify that the software is working properly, you can perform a set of operational integrity checks on the newly upgraded network. These may include:

■Some standard checks based on services active.

A basic service verification test can Ping to specific IP addresses.

■Connectivity checks based on network topology.
