6.3 SNMP Interface
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 MBT-5000.
• The SNMP Agent. This is the software that runs on the MBT-5000. The MBT-5000 SNMP
Agent supports both SNMPv1 and SNMPv2c.
• The user-supplied Network Management System (NMS). This is the software that runs on
the manager.
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 MBT-5000:
MIB File/Name

MBT-5000 MIB file
MIB file consists of all of the OIDs for management of the amplifier functions
FW-0000102x.mib
MBT-5000 Traps
MIB file
Trap MIB file is provided for SNMPv1 traps common for MBT-5000.
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 MBT-5000 uses Community Strings as a password scheme that provides authentication
before gaining access to the MBT-5000 agent’s MIBs. They are used to authenticate users and
determine access privileges to the SNMP agent.
