6.2 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 LBC‐4000.
• The SNMP Agent. The software that runs on the LBC‐4000. The LBC‐4000 SNMP Agent
supports both SNMPv1 and SNMPv2c.
• The user‐supplied Network Management System (NMS). The software that runs on the
manager.
6.2.1 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 the LBC‐4000:

FW-0020543.mib
LBC-4000 Traps MIB
file
Trap MIB file is provided for SNMPv1 traps common for LBC-4000.
6.2.2 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 LBC‐4000 uses Community Strings as a password scheme that provides authentication
before gaining access to the LBC‐4000 agent’s MIBs. They are used to authenticate users and
determine access privileges to the SNMP agent.
