SNMP Interface
The Simple Network Management Protocol (SNMP) is an application-layer protocol designed to
facilitate the exchange of management information between network devices. The CDD-880
SNMP agent supports both SNMPv1 and v2c.
For proper SNMP operation, the CDD-880 MIB files must be used with the
associated version of the CDD-880 router M&C. Please refer to the CDD-880 FW
Release Notes for information on the required FW/SW compatibility.
IMPORTANT
5.3.1 Management Information Base (MIB) Files
MIB files are used for SNMP remote management and consist of Object Identifiers (OIDs). Each
OID is a node that provides remote management of a particular function. A MIB file is a tree of
nodes that is unique to a particular device.
The following MIB files are associated with the CDD-880:
MIB File/Name
FW10874-2-.mib
ComtechEFData
Root MIB file
FW-0000423- .mib
CDD-880 MIB file
These MIB files should be compiled in a MIB Browser or SNMP Network Monitoring System server.
Note: The SNMP agent supports both SNMPv1 and SNMPv2c.
5.3.2 SNMP Community Strings
The router uses community strings as a password scheme that provides authentication before
gaining access to the router agent's MIBs.
In SNMPv1 and SNMPv2c, the 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. A packet sniffer can easily obtain the
community string by viewing the SNMP traffic on the network.
The community string is typed into the MIB Browser or Network Node Management software
and is used to authenticate users and determine access privileges to the SNMP agent.
