Upgrading Software This section describes how to upgrade the software on your existing hardware

Onlyusing either automatic or manual recovery. If you are upgrading or replacing your bridge/router, switch or main processor module (NETBuilder II), follow the procedure in “Upgrading Hardware and Software” on page 44.

Automatic Recovery This section describes how to perform an upgrade of the Enterprise OS software that does not include a hardware upgrade. 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. See Table 4 on page 40 or “bcmsysupgrade” on page 81 for a list of the options available to use with the bcmsysupgrade utility.

To upgrade the bridge/router software to the default version, follow these steps:

1Back up your current software to the NMS using:

bcmsysupgrade [options] -s:from_nb <device>

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

The bcmsysupgrade utility only backs up the files in the primary boot source. To archive both the primary and secondary boot sources, use bcmbackup instead of bcmsysupgrade. See “bcmbackup” on page 73 for more information.

2NETBuilder II with CEC only — (The CEC module is not supported in software version 11.3. However, you can use the utilities to upgrade your CEC module to software version 10.1 or earlier.) If you are running CEC firmware versions 2.0 or 2.1, which are standard with NETBuilder II software versions 8.0, 8.1, and 8.2, you must upgrade your CEC firmware before proceeding to the next step.
