Product, Model, and Part Number Mapping
You can use the master configuration file to direct system upgrades to a software image and configuration
files based on a system model number, a firmware part number, or a system’s MAC address.
The part number has precedence over the model number, which has precedence over the original version.
For example,
CONFIG_FILES_2345-11560-001=”system1_2345-11560-001.cfg,
sip_2345-11560-001.cfg” will override CONFIG_FILES_CX5100=”system1_CX5500.cfg,
sip_CX5100.cfg”
, which will override CONFIG_FILES=”system1.cfg, sip.cfg ” for the CX5100.
You can also add variables to the master configuration file that are replaced when the system reboots. The
variables include
SYSTEM_MODEL, SYSTEM_PART_NUMBER, and SYSTEM_MAC_ADDRESS .
