MPCMM0001 Chassis Management Module Software Technical Product Specification 141
SNMP
17.1 CMM MIB
The CMM comes with a text file (mpcmm0001.mib) that describes the CMM and platform objects
to be managed. 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 mpcmm0001.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.
17.2 MIB 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. Only the objects described in this section can be
customized for the CMM. Other unlisted MIB II objects will work.
17.2.1 MIB Tree
The MIB tree representing the locations of the custom MIB is shown in Figure 4, “CMM Custom
MIB Tree” on page 142.
Next to each object is the object identifier number in parentheses () for each object in the MIB tree.
For example, using the tree below it can be calculated that the full OID for blade16 location on the
CMM is 1.3.6.1.4.1.343.2.14.2.10.4.16 by starting at the top of the tree and following the numbers
down to blade16.
