10.3.3 Basics of a MIB Definition File


10.3.3 Basics of a MIB Definition File
The SNMP agent function has management information called MIB. The function returns this MIB information in response to a request from the manager.
Standard MIB
The XSCF supports MIB-II (supporting SNMPv2 and v3) and MIB-I (supporting SNMPv1), which are defined as Internet standards, to mainly manage the following information:
  1. Basic XSCF-LAN-related information (e.g., administrator name)
  2. XSCF-LAN communication processing-related information
  3. XSCF SNMP agent operation-related information
For details on the standard MIBs supported by the XSCF, see "Appendix D XSCF MIB Information."
Extended MIB
In addition to the standard MIBs, these systems support the following extended MIB:
  1. XSCF extended MIB: Extended MIB for the XSCF SNMP agent
This MIB mainly manages the following information:
  1. - Basic system-related information (e.g., serial number)
  2. - Various system-related status information (e.g., high-level Oracle Solaris operation status)
  3. - Information on physical partitions in the system
  4. - Information on parts failures in the system
  5. - Information related to power values in the system
The following example shows the data in management information for the XSCF extended MIB.
scfMachineType OBJECT-TYPE

DESCRIPTION "System model name and model type name."

scfNumberOfCpu OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-only
STATUS mandatory
DESCRIPTION "Number of CPUs"
::= { scfInfo 2 }
scfSysSerial OBJECT-TYPE
SYNTAX DisplayString
ACCESS read-only
STATUS mandatory
DESCRIPTION "System serial number"
::= { scfInfo 3 }
For details on the XSCF extended MIB supported by the XSCF, see "Appendix D XSCF MIB Information."
Installing an Extended MIB Definition File
A MIB definition file is defined according to the ASN1 standard notation.
The XSCF extended MIB definition file defines management information so that these systems are monitored by the SNMP manager. To monitor the server, install the XSCF extended SNMP definition file for the SNMP manager.

For details on how to install it, see the manual of the SNMP manager used. For the place to obtain the extended MIB definition file, see the latest Product Notes for your server or the MIB definition file-related information at the firmware download site.
