This object contains the hash value of the contents of the config file. If the authentication algorithm is MD5, the length is 128 bits. If the authentication algorithm is SHA-1, the length is 160 bits. The hash calculation MUST follow the requirements defined in the PacketCable Security specification. When the MTA SNMP Enrollment mechanism is used, this hash value is calculated and sent to the MTA prior to sending the config file. This object value is then provided by the Provisioning server via an SNMP SET operation. When the MTA SNMP Enrollment mechanism is not in use, the hash value is provided in the configuration file itself and it is also calculated by the MTA. This object value MUST represent the hash value calculated by the MTA. When the MTA SNMP Enrollment mechanism is not in use, the MTA must reject all SNMP SET operations on this object and return an 'inconsistentValue' error.
