6.7.3.3.1.2 HiPR-900 MIB File

Each HiPR-900 unit firmware package is bundled with three MIB files (found inside mibs.zip file):

• dataradio-regs.mib: contains a top level set of managed object definitions aimed at managing Datara-

dio products.

• 1213.mib: contains a set of managed object definitions aimed at managing TCP/IP-based internets.

• hipr900.mib: contains a set of managed object definitions aimed at managing Dataradio HiPR-900

modems.

6.7.3.3.1.3 OID

In SNMP, each object has a unique OID consisting of numbers separated by decimal points. These object

identifiers naturally form a tree. Figure 41 illustrates this tree-like structure for 1213.mib, which comes

bundled with every HiPR unit package. A path to any object can be easily traced starting from the root

(top of the tree). For example, object titled “SNMP” has a unique OID: 1.3.6.1.2.1.11. The MIB asso-

ciates each OID with a label (e.g. “SNMP”) and various other parameters. When an SNMP manager

wants to obtain information on an object, it will assemble a specific message (e.g. GET packet) that in-

cludes the OID of the object of interest. If the OID is found, a response packet is assembled and sent

back. If the OID is not found, a special error response is sent that identifies the unmanaged object.

6.7.3.3.1.4 MIB Browser

Dataradio recommends opening all MIB files with a MIB browser. For simple networks, a basic, free ap-

plication such as”iReasoning MIB browser” could be used. However, for managing complex networks

Dataradio recommends a more advanced software application, such as “Castle Rock SNMPc Network

Manager”. In a MIB browser, each object (or node) can be selected and its properties (including its OID)

can be observed.

Note: Both “Read Community” and “Write Community” passwords are required to operate

SNMP MIB. For all HiPR-900 radiomodems the same password is used for both read and write.
