6.2.2 SNMP Interface
The Simple Network Management Protocol (SNMP) is an Internet-standard non-secure protocol
for managing devices on IP networks. An SNMP-managed network consists of three key
components:
•
The managed device. This includes the CDD-880 Multi Receiver Router.
•
The SNMP Agent. The software that runs on the CDD-880. The CDD-880 SNMP Agent
supports both
SNMPv1
and
SNMPv2c
.
•
The user-supplied Network Management System (NMS). The software that runs on the
manager.
6.2.2.1 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. 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 operation of the
CDD-880:

CDD-880 MIB file
MIB file consists of all of the OIDs for CDD-880 M&C.
6.2.2.2 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 CDD-880 uses Community Strings as a password scheme that provides authentication
before gaining access to the CDD-880 Agent MIBs. They are used to authenticate users and
determine access privileges to the SNMP agent.
Type the SNMP Community String into the user-supplied MIB Browser or Network Node
Management software. Two Community Strings are defined for SNMP access:
