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.
