description:
|
|
Modern networking hardware implementing the Open Compute Project ONIE
|
|
infrastructure shall provide a non-volatile memory with a table whose the
|
|
content is well specified and gives many information about the manufacturer
|
|
(name, country of manufacture, etc) as well as device caracteristics (serial
|
|
number, hardware version, mac addresses, etc). The underlaying device type
|
|
(flash, EEPROM,...) is not specified. The exact location of each value is also
|
|
dynamic and should be discovered at run time because it depends on the
|
|
parameters the manufacturer decided to embed.
