19.1CMM MIB

The CMM comes with a text file (ZT 7102.mib) that describes the CMM objects to be managed, as well as all of the managed objects in the platform. A remote application such as an SNMP/MIB manager can compile and read this file and utilize this information to manage the sensor devices on CMM, chassis, and server blades currently present. The ZT 7102.mib is located in the /usr/local/cmm directory in the CMM. Users can utilize ftp or rcp to get this file from the CMM.

19.2MIB Design

The CMM supports the following MIB II objects. The writeable objects can be set in their respective fields in the /etc/snmpd.conf file.

Table 42. MIB II Objects - System Group

Object	Syntax	Size	Access	Value
sysDscr	DisplayString	0..127	read-only	“Linux ZT 7102 2.4.2-1 #156 [DATE] armv5”
				Date is the actual current date.
	OBJECT			iso(1).org(3).dod(6).internet(1).private(4).enter
sysObjectID			read-only	prises(1).intel(343).products(2).Chassis-Mana
	IDENTIFIER
				gement(14).ZT 7102(1)
sysUpTime	Days and Time		read-only	Time since ZT7102 began running
sysContact	DisplayString	0..127	read-write	max. 128 bytes
sysName	DisplayString	0..8	read-write	Default:”ZT 7102”
sysLocation	DisplayString	0..127	read-only

19.2.1CMM MIB Objects

Detailed descriptions of the MIB objects can be found in the ZT7102.mib file located on the CMM.

19.2.2Querying Non-IPMI Compliant Blades and Power Supplies

Slot control is a target that is specific to SNMP that is displayed in response to a listtargets command when used on an unoccupied slot in the chassis. This target is not available if the slot is occupied. The Slot Control target allows the user to perform other commands against that slot without an IPMI-compliant blade or IPMI-compliant power supply present.

19.3SNMP Agent

The SNMP agent (snmpd) listens to SNMP v1 queries (gets/sets) by default, evokes the corresponding MIB Module to process the request, and sends the SNMP response with return data to the SNMP/MIB manager. All SNMP “set” queries are logged in the command log file.
