DM240XR High-Speed Digital Modulator User Interfaces
MN-DM240XR– Revision 13 4–39
4.5 Ethernet Port User Interface
The Ethernet Port of the DM240XR allows for complete control and monitoring of all DM240XR
parameters and functions via a 10 Base-T or 100 Base-T Ethernet Connection.
4.6 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. Refer to section 8 MIB Protocol
4.7 The Management Information Base (MIB)
Refer to Section 8 MIB Protocol
Management objects are defined in the Management Information Base (MIB), which uses a
hierarchical naming scheme. Within this scheme, each object is identified by an Object Identifier
(OID), 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 4-4a and 4-4b).
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:
4.7.1 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.
4.7.2 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.
4.7.3 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.
