serial-number 1.3.6.1.4.1.11.2.3.9.4.2.1.1.3.3

Identifies the serial number for the device. If the SERIAL-NUMBER object is set by the user, then setting the object does not need to be protected. If the SERIAL-NUMBER object is set at the factory, then the SERVICE-PASSWORD object must be set correctly before the SERIAL-NUMBER object is writable. If this is a writable object, the POS should indicate the maximum supported string length. If possible, encode the serial number in a symbol set (like Roman-8) that matches the ASCII character set and limit the characters used to ASCII characters. Additional information: This value IS AFFECTED BY NVRAM resets, it is set to the default value of XXXXXXXXXX, when a NVRAM init is done.
