Object Identifiers
Each object has a u nique identifier called an OID, which consist of a se-
quence of integer v alues represented in 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, the internet OI D is equ al to 1. 3.6.1. Seven MIB

MIB Object Identifiers
MIB-II Item OID Group or Table Description
ifNumber 1.3.6.1.2.1.2.1.0 Interfaces Group Indicates the number of adapters
present in the system. For the 700
Color Computer, if one adapter is
present in the system, then ifNum-
ber =1andifIndex=1.
ifIndex 1.3.6.1.2.1.2.2. 1.1.ifIndex Interfaces Table (ifTable) A unique value for each interface.
The value ranges 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
equal to 1 for Other.
ipAdEntAddr 1.3.6. 1.2.1.4.20.1.1.IpAddress IP address Table
(ipAddrTable)
The IP address to which this entry’s
addressing information pertains
(same as 700 IP address),whereIP

tifies the interface to which this
entry is applicable (same as ifIndex).

(ipAddrTable)
The su bnet mask associated with

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