6.3.1 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 CDM‐750:
MIB File/Name
(where 'x' is revision letter)
FW10874-2-.mib
ComtechEFData Root MIB file
FW-0000083L .mib
CDM-750 MIB file
FW-0000084- .mib
CDM-750 Traps MIB file

6.3.2 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 CDM‐750 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.
Three Community Strings are defined for SNMP access:
•
Read Community
•
Write Community
•
Traps Community
For proper SNMP operation, the CDM‐750 MIB files must be used with the
associated version of the CDM‐750 modem M&C. Refer to the CDM‐750 FW Release
Notes for information on the required FW/SW compatibility.
