ObjectIdentifiers
Each object has a unique identifier called an OID, which consist of a se-
quence of integer values representedin dot notation.Objects are stored in
a tree structure and OIDs are assigned based on the position of the object
in the tree. For example, theinternet OID is equal to 1.3.6.1. Seven MIB
OIDsareshowninthefollowingtable:
MIBObject Identifiers
MIB-IIItem OID Groupor Table Description
ifNumber 1.3.6.1.2.1.2.1.0 Interfaces Group Indicatest he number ofadapters
presentin the system. For the 700
Color Computer, if one adapter is
presentin the system, then ifNum-
ber=1andifIndex=1.
ifIndex 1.3.6.1.2.1.2.2.1.1.ifIndex Interfaces Table (ifTable) A uniqu e valuefor each interface.
The valueranges between 1 and the
value of ifNumber.
ifDescr 1.3.6.1.2.1.2.2.1.2.ifIndex Interfaces Table (ifTable) A textual string containing informa-
tion about the interface.
ifType 1.3.6.1.2.1.2.2.1.3.ifIndex Interfaces Table (ifTable) An integer containing information
about the type of the interface. It is
equalto 1 for Other.

Configuring with SNMP
The community string allows an SNMP manager to manage the 700 Col-
or Computer witha specified privilege level. The default read-only com-
munity string is “public” and “private” is the default read/wr ite communi-
ty string. See the specific configuration parameter to fi ndi tsO ID. To
configure the700 Color Computers using SNMP:
1Configure700ColorComputersforRForEthernetcommunications.
2Determine the OID (ObjectIdentifier) for the parameter to be chan-
ged. The Intermec base OID is 1.3.6.1.4.1.1963.
3Use your SNMP management station to get and set variables that are
defined in the IntermecMIBs. You can set the traps, identification, or
security configuration parameters for SNMP. See A ppendix A, “Confi-
gurable Settings,” to learn more about these parameters.
