Description: The first octet, octet 0, indicates which System Global object has changed. This value will be one of the following: 0x00 - System Date & Time 0x01 - ACO Configuration (NOT SUPPORTED AT PRESENT) 0x02 - System Timing Interface (NOT SUPPORTED AT PRESENT) 0x03 - PSU Ring Voltage 0x04 - PSU Pulse Meter Tone 0x05 - PSU Ring Frequency 0x06 - SNMP Community Name (NOT SUPPORTED AT PRESENT) 0x07 - SNMP Trap Types Enabled 0x08 - SNMP Trap Receiver 1 IP Address 0x09 - SNMP Trap Receiver UDP Port 0x0A - SNMP Trap Receiver 2 IP Address 0x0B - SNMP Trap Receiver 2 Traps Enabled 0x0C - SNMP Trap Receiver 3 IP Address 0x0D - SNMP Trap Receiver 3 Traps Enabled 0x0E - SNMP Trusted Hosts Enabled 0x0F - SNMP Telnet Port (NOT SUPPORTED AT PRESENT) 0x10 - Transceiver Channel Attributes 0x11 - CPU Build Options

The trailing octets, octet 1 through the last octet in the object store the new data for the object that has changed.

If octet 0 is 0x00 (System Date & Time has changed) octets 1 through the last octet in the octet string store the new value. The new value will be of the format defined by umc1SystemDateTime.

If octet 0 is 0x01 (ACO Configuration has changed) octet 1 stores the new value. The format of the new value is defined by umc1SystemSysProvACOConfig. (NOT SUPPORTED AT PRESENT)

If octet 0 is 0x02 (System Timing Interface has changed), the trailing octets contain the value. OPEN ISSUE: We will add the description once we ascertain the format of the CPU database record for the current release. The format of the data returned is defined by umc1SystemSysTimingSource. (NOT SUPPORTED AT PRESENT)

If octet 0 is 0x03 (PSU Ring Voltage has changed), octet 1 contains PSU Ring Voltage value. The format of the data returned is defined by umc1SystemSysProvPsuRingVoltage.

If octet 0 is 0x04 (PSU Meter Tone has changed), octets 1 through 4 contain PSU Meter Tone value, where octets 1, 2, 3, and 4 contain bits 24..31, 16..23, 8..15, 0..7, respectively. The format of the data returned is defined by umc1SystemSysProvPsuPulseMeterTone.

If octet 0 is 0x05 (PSU Ring Frequency has changed), octets 1 through 2 contain PSU Ring Frequency value, where octets 1 and 2 contain bits 8..15 and 0..7, respectively. The format of the data returned is defined by umc1SystemSysProvPsuRingFreq.

If octet 0 is 0x06 (SNMP Community name has changed), octets 1 through the last octet in the octet string contain the new SNMP community name. (NOT SUPPORTED AT PRESENT - we do not issue this information for security reasons !).

If octet 0 is 0x07 (SNMP Trap Types Enabled has changed), octet 1 contains the new value for object umc1SnmpTrapTypesEnabled.

If octet 0 is 0x08 (SNMP Trap Receiver 1 IP Address has changed), octets 1 through 4 contain the new value of the object umc1SnmpTrapRcvrAddress.

If octet 0 is 0x09 (SNMP Trap Receiver UDP Port has changed), octets 1 through 4 contain the new value of the object umc1SnmpTrapRcvrPort.

If octet 0 is 0x0A (SNMP Trap Receiver 2 IP Address has changed), octets 1 through 4 contain the new value of the object umc1SnmpMgmtHost2Address.

If octet 0 is 0x0B (SNMP Trap Receiver 2 Traps Enabled has changed), octet 1 contains umc1SnmpMgmtHost2TrapsEnabled.

If octet 0 is 0x0C (SNMP Trap Receiver 3 IP Address has changed), octets 1 through 4 contain the new value of the object umc1SnmpMgmtHost3Address.

If octet 0 is 0x0D (SNMP Traps Receiver 3 Traps Enabled has changed), octets 1 through 4 contain the new value of the object umc1SnmpMgmtHost3TrapsEnabled.

If octet 0 is 0x0E (SNMP Trusted Hosts Enabled has changed), octets 1 through 4 contain the new value of the object umc1SnmpTrustedHostsEnabled.

If octet 0 is 0x0F (SNMP Telnet Port has changed), octets 1 through 4 contain the new value of the object umc1SnmpTelnetPort. (NOT SUPPORTED AT PRESENT - this is managed via the IPMI Plugin Provisioning record table and associated TRAPs).

If octet 0 is 0x10 (Transceiver Channel Attributes), the trailing octets contain the value. The remainder of the octet contents are described as follow : octet[1] 'version' of data (1 for this release)

for octet[1] (version ) equal 1 octet[2] 'action', either record delete or modify/create. See 'DbActionType'. octet[3] 'dbSpecifier', set to _DbChanAtrb_ (0x0A) octet[4] 'dbRecLen', length of the database record to follow in number of bytes. The database record will be held in octets[5] - [?]. The actual number of octets will vary, dependent upon the type of Channel Attribute record being reported. octet[5] - [?] The actual CPU database record.

If octet 0 is 0x11 (CPU Build Options), the trailing octets contain the value of the changed option(s) object 'umc1CpuSoftwareFeatures'. If the CPU does not support the reporting of this data the values of all bytes of the object returned will be set to zero (including the version octet[0]).
