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 CDD-56X:
MIB File/Name

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 CDD-56X uses Community Strings as a password scheme that provides authentication before
gaining access to the demodulator agent’s 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.
The user defines three Community Strings for SNMP access:
• Read Community
default = public
• Write Community
default = private
• Trap Community
default = comtech
