7.2 SNMP Interface
Use of the Ethernet-based SNMP interface is recommended only for advanced users.
All other users are strongly encouraged to use the HTTP (Web Server) Interface for
monitor and control of the CDM-760.
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 CDM-760 Advanced High-Speed Trunking Modem.
• The SNMP Agent. This is the software that runs on the CDM-760. The CDM-760 SNMP Agent
supports both SNMPv1 and SNMPv2c.
• The user-supplied Network Management System (NMS). This is the software that runs on
the manager.
7.2.1 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. You should compile these MIB files in a user-supplied MIB Browser or SNMP
Network Monitoring System server. The following MIB files are associated with the CDM-760:
MIB File/Name
(where ‘x’ is revision letter)
Description

ComtechEFData Root MIB file
ComtechEFData MIB file gives the root tree for ALL Comtech EF Data
products and consists of only the following OID:

Module: ComtechEFData
FW-0020630x.mib
CDM-760 MIB file
MIB file consists of all of the OIDs for management of the modem functions
FW-0020631x .mib
CDM-760 Traps MIB file
Trap MIB file is provided for SNMPv1 traps common for modem.
7.2.2 SNMP Community Strings
CAUTION
In SNMP v1/v2c, the SNMP Community String is sent unencrypted in the SNMP
packets. The network administrator must make sure that SNMP packets travel only
over a secure and private network, if security is important.
The CDM-760 uses Community Strings as a password scheme used to authenticate users and
determine access privileges to the SNMP Agent MIBs. Type the SNMP Community String into the
user-supplied MIB Browser or Network Node Management software.
