4.6.3.2 SNMP Test
1.
Once it is determined that the SFC Upconverter is reachable, compile the custom
Management Information Base (MIB) for use by the Network Management Station (NMS).
The MIB uses a hierarchical naming scheme. Each managed object in the Upconverter is
identified by an Object Identifier (OID), a sequence of non-negative integers that uniquely
describes the path taken through the hierarchical structure.
2.
Using the Upconverter IP Address, perform a Walk of the MIB to retrieve all the MIB
objects managed in the Upconverter.
4.6.4 Management Information Base Structure
This section defines the terminology and hierarchy associated with management information base
structure at Radyne ComStream Corporation.
4.6.4.1 Simple Network Management Protocol (SNMP)
Simple Network Management Protocol (SNMP), as its name suggests, is a relatively simple
protocol by which management information for a network device may be inspected and/or altered by
remote administrators.
4.6.4.2 The Management Information Base (MIB)
Management objects are defined in the Management Information Base (MIB), which uses a
hierarchical naming scheme. In this scheme, an Object Identifier (OID) identifies each object. The
OID is a sequence of non-negative integers that uniquely describes the path taken through the
hierarchical structure.
MIB objects may then be specified either from the Root (which has no designator), or alternatively
from anywhere within the hierarchical structure.
For example: 1.3.6.1.4.1.2591.4 is equivalent to {iso(1). org(3). dod(6). internet(1). private(4).
enterprises(1). Radyne(2591). RCS10L(4)} (See Figure 4-4).
In general, we are mainly concerned with just two groups that reside in the
internet subtree, namely
the mgmt , and private groups. For completeness however, the four major groups are discussed
below:
Directory {internet 1} 1.3.6.1.1
This area was reserved to describe how the OSI directory structure may be used in the Internet. To
date this has not been implemented and therefore is of little interest to us.
Mgmt {internet 2} 1.3.6.1.2
This area was reserved to describe objects in the standard MIB. As RFCs defining new groups are
ratified, the Internet Assigned Numbers Authority (IANA) assigns new group IDs.
Experimental {internet 3} 1.3.6.1.3
This subtree provides an area where experimentation is carried out. Only those organizations
directly involved in the experiment have any interest in this subtree.
