DHCP Server Configuration
This
chapter
describes
the
commands
to
configure
the
IPv4
DHCP
server
functionality
on
a
SecureStack
C2
switch.
DHCP Overview
Dynamic
Host
Configuration
Protocol
(DHCP)
for
IPv4
is
a
network
layer
protocol
that
implements
automatic
or
manual
assignment
of
IP
addresses
and
other
configuration
information
to
client
devices
by
servers.
A
DHCP
server
manages
a
user
‐
configured
pool
of
IP
addresses
from
which
it
can
make
assignments
upon
client
requests.
A
relay
agent
passes
DHCP
messages
between
clients
and
servers
which
are
on
different
physical
subnets.
DHCP Relay Agent
The
DHCP/BOOTP
relay
agent
function
can
be
configured
on
all
of
the
SecureStack
C2’s
routing
interfaces.
The
relay
agent
can
forward
a
DHCP
client’s
request
to
a
DHCP
server
located
on
a
different
network
if
the
address
of
the
server
is
configured
as
a
helper
address
on
the
receiving
interface.
The
relay
agent
interface
must
be
a
VLAN
which
is
configured
with
an
IP
address.
Refer
to
the
ip
helper
‐
address
command
for
more
information.
DHCP Server
DHCP
server
functionality
allows
the
SecureStack
C2
switch
to
provide
basic
IP
configuration
information
to
a
client
on
the
network
who
requests
such
information
using
the
DHCP
protocol.
DHCP
provides
the
following
mechanisms
for
IP
address
allocation
by
a
DHCP
server:
•
Automatic—DHCP
server
assigns
an
IP
address
to
a
client
for
a
limited
period
of
time
(or
until
the
client
explicitly
relinquishes
the
address)
from
a
defined
pool
of
IP
addresses
configured
on
the
server.
•
Manual—A
client’s
IP
address
is
assigned
by
the
network
administrator,
and
DHCP
is
used
simply
to
convey
the
assigned
address
to
the
client.
This
is
managed
by
means
of
“static”
address
pools
configured
on
the
server.
The
amount
of
time
that
a
particular
IP
address
is
valid
for
a
system
is
called
a
lease.
The
SecureStack
C2
maintains
a
lease
database
which
contains
information
about
each
assigned
IP
