8: SNMP : Simple Network
Management Protocol
•
•
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
Raven
‐
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
Raven
‐
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
Raven
‐
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
Raven
‐
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
Raven
‐
E
is
capable
of
sending
the
linkUp
trap
when
the
network
connection
becomes
available.
