SNMP Interface

The Simple Network Management Protocol (SNMP) is an Internet-standard protocol for managing
devices on IP networks. An SNMP-managed network consists of three key components:
The managed device. This includes the SLM-5650A Satellite Modem.
•
The SNMP Agent. The software that runs on the SLM-5650A. The SLM-5650A SNMP
•
Agent supports SNMPv1, SNMPv2c, and SNMPv3.
The user-supplied Network Management System (NMS). The software that runs on
•
the manager.

6.4.1 Management Information Base (MIB) Files

MIB files are used for SNMP remote management of a unique device. A MIB file consists of a
tree of nodes called Object Identifiers (OIDs). Each OID provides remote management of a
particular function. These MIB files should be compiled in a user-supplied MIB Browser or
SNMP Network Monitoring System server.
The following MIB files are associated with the SLM-5650A:
MIB File/Name
( 'x' indicates revision letter)
fw10874-2x.mib
ComtechEFData MIB file
FW-0000049x.mib
SLM-5650A OID MIB File
FW-0000050x.mib
SLM-5650A Traps MIB file

6.4.2 SNMP Community Strings

In SNMP v1/v2c, the SNMP Community String is sent unencrypted in the SNMP
packets. Caution must be taken by the network administrator to ensure that
SNMP packets travel only over a secure and private network if security is a
concern.
The SLM-5650A uses Community Strings as a password scheme that provides authentication
before gaining access to the modem agent's MIBs. They are used to authenticate users and
determine access privileges to the SNMP agent.
Description
ComtechEFData MIB file gives the root tree for ALL Comtech EF Data products and
consists of only the following OID:
Name: comtechEFData
Type: MODULE-IDENTITY
OID: 1.3.6.1.4.1.6247
Full path:
iso(1).org(3).dod(6).internet(1).private(4).enterprises(1).comtechEFData(6247)
Module: ComtechEFData
MIB file consists of all of the OID's for management of the modem functions.
Trap MIB file is provided for SNMPv1 traps common for base modems.
