10 10: SNMP : Simple Network
Management Protocol
• SNMP Configuration
• SNMP MIB Definition
Sample
The Simple Network Management Protocol (SNMP) was
designed to allow remote management and monitoring of a
variety of devices from a central location. The SNMP
management system is generally composed of agents (such as
your PinPoint‐E, a router, a UPS, a web server, a file server, or
other computer equipment) and a Network Management
Station (NMS) which monitors all the agents on a specific
network. Using the management information base (MIB), an
NMS can include reporting, network topology mapping, tools
to allow traffic monitoring and trend analysis, and device
monitoring.
Authentication ensures SNMP messages coming from the
agent, such as the PinPoint‐E, have not been modified and the
agent may not be queried by unauthorized users. SNMPv3
uses a User‐Based Security Model (USM) to authenticate and,
if desired or supported, message encryption. USM uses a user
name and password specific to each device.
The PinPoint‐E can be configured as an SNMP agent and
supports SNMPv2c and SNMPv3.
Management Information Base (MIB)
The management information base (MIB) is a type of database
used to compile the information from the various SNMP
agents. Reports from various agents, such as the PinPoint‐E,
are sent as data in form designed to be parsed by the NMS into
its MIB. The data is hierarchical with entries addressed
through object identifiers.
SNMP Traps
SNMP traps are alerts that can be sent from the managed
device to the Network Management Station when an event
happens. Your PinPoint‐E is capable of sending the linkUp trap
when the network connection becomes available.
