System
Management
System
management
refers
to
enterprise
‐
wide
administration
of
distributed
systems
including
(and
commonly
in
practice)
computer
systems.
Centralized
management
has
a
time
and
effort
trade
‐
off
that
is
related
to
the
size
of
the
company,
the
expertise
of
the
IT
staff,
and
the
amount
of
technology
being
used.
This
device
supports
many
system
management
protocols,
such
as
SNMP,
and
Telnet
with
CLI.
You
can
setup
those
configurations
in
the
"System
Management"
section.
4.1.1
SNMP
In
brief,
SNMP,
the
Simple
Network
Management
Protocol,
is
a
protocol
designed
to
give
a
user
the
capability
to
remotely
manage
a
computer
network
by
polling
and
setting
terminal
values
and
monitoring
network
events.
In
typical
SNMP
uses,
one
or
more
administrative
computers,
called
managers,
have
the
task
of
monitoring
or
managing
a
group
of
hosts
or
devices
on
a
computer
network.
Each
managed
system
executes,
at
all
times,
a
software
component
called
an
agent
which
reports
information
via
SNMP
to
the
manager.
SNMP
agents
expose
management
data
on
the
managed
systems
as
variables.
The
protocol
also
permits
active
management
tasks,
such
as
modifying
and
applying
a
new
configuration
through
remote
modification
of
these
variables.
The
variables
accessible
via
SNMP
are
organized
in
hierarchies.
These
hierarchies,
and
other
metadata
(such
as
type
and
description
of
the
variable),
are
described
by
Management
Information
Bases
(MIBs).
The
device
supports
several
public
MIBs
and
one
private
MIB
for
the
SNMP
agent.
The
supported
MIBs
are
as
follow:
MIB-II (RFC 1213, Include IPv6), IF-MIB, IP-MIB, TCP-MIB, UDP-MIB, SMIv1 and
SMIv2, SNMPv2-TM and SNMPv2-MIB, and AMIB (AMIT Private MIB)
