SNMP
Management
Scenario
Scenario
Application
Timing
There
are
two
application
scenarios
of
SNMP
Network
Management
Systems
(NMS).
Local
NMS
is
in
the
Intranet
and
manage
all
devices
that
support
SNMP
protocol
in
the
Intranet.
Another
one
is
the
Remote
NMS
to
manage
some
devices
whose
WAN
interfaces
are
connected
together
by
using
a
switch
or
a
router
with
UDP
forwarding.
If
you
want
to
manage
some
devices
and
they
all
have
supported
SNMP
protocol,
use
either
one
application
scenario,
especially
the
management
of
devices
in
the
Intranet.
In
managing
devices
in
the
Internet,
the
TR
‐
069
is
the
better
solution.
Please
refer
to
last

section.
Scenario
Description
The
NMS
server
can
monitor
and
configure
the
managed
devices
by
using
SNMP
protocol,
and
those
devices
are
located
at
where
UDP
packets
can
reach
from
NMS.
The
managed
devices
report
urgent
trap
events
to
the
NMS
servers.
Use
SNMPv3
