IP address; another contains the current operational status of TCU port 
number 6. To access a specific bit of information, the user specifies an 
object identifier (OID)

 which is a series of numbers separated by decimal 

points that indicates the path through a MIB trunk and subsequent 
branches to the specific leaf that contains the desired information, 
effectively identifying the MIB object. 

On the SNMP Tool screen, a row of MIB commands is presented. These 
commands, which are described below, may be invoked in the same 
manner as screen commands. Some of them may also be invoked through 
function keys. 

The Community Name field lets the user input a password to access MIBs 
that have been set up to refuse access to users without the proper 
password.

It is likely that many of the MIB leaves which the user will be accessing 
will reside within the same family of branches in the MIB (e.g.: they all 
begin with 1.3.6.1). The user may use the OID Prepend field to specify a 
prefix (e.g.: 1.3.6.1) which will be applied automatically (unless otherwise 
directed) to subsequent OIDs, allowing the user to leave out this OID 
portion when accessing MIB leaves on a common family of branches. 

Use the 

 command to view a single MIB leaf by specifying its OID. It 

displays the following information for each MIB object:

•

Specified OID - lists the OID for each object displayed.

•

Size - lists the number of memory bytes occupied by the object.

•

Type - lists the object’s variable type (e.g., int = integer).

•

Data - lists the object’s current value.

1.

Invoke 

 on screen or press the F6 function key. 

2.

After “<GET> OID (=|F9)” appears, specify the desired OID by one of 
the following methods:

•

Enter the OID minus the OID’s prepend: if the prepend is 1.3.6.1, 
and the user enters 4.1.3, OID 1.3.6.1.4.1.3 is requested.
