4.6.3.1 Ping Program


1.

PING is an application that uses the ICMP protocol to report if a host is responding. To
check whether the SFC1800A Upconverter is reachable, use the PING program installed
on your computer along with the modem IP Address set in Section 3.2.3.


Example: ping 192.168.0.35


2.

If everything is functioning correctly, replies from the modem will appear on the computer
screen along with the time it took to respond. If unsuccessful, verify the following:

a.

The cables are secured.

b.

The Link Light is illuminated.

c.

The IP Address that is used matches the Modem’s IP Address.

d.

The Server and Modem are on the same subnet.

4.6.3.2 SNMP Test


1.

Once it is determined that the SFC1800A 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.

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:
