Addressing
64
•
IP
ranges:
A
range
of
IPv4
addresses
is
represented
with
the
form
a.b.c.d
‐
e.f.g.h
.
Note
that
ranges
are
not
limited
to
IPv4
netmask
boundaries.
They
may
include
any
span
of
IP
addresses.
For
example,
192.168.0.10
‐
192.168.0.15
represents
six
IPv4
hosts
in
consecutive
order.
A
range
of
IPv6
addresses
is
specified
in
the
same
way.
For
example,
2001:DB8::1
‐
2001:DB8::6
Example 1: Adding an IP host
This
example
adds
the
IP
host
www_srv1
with
IPv4
address
192.168.10.16
to
the
address
book:
Device:/>
add
Address
IPAddress
www_srv1
Address=192.168.10.16
Example 2: Adding an IP network
This
example
adds
an
IP
network
named
wwwsrvnet
with
address
192.168.10.0/24
to
the
address
book:
Device:/>
add
Address
IPAddress
wwwsrvnet
Address=192.168.10.0/24
Example 3: Adding an IP range
This
example
adds
a
range
of
IPv4
addresses
from
192.168.10.16
to
192.168.10.21
and
names
the
range
wwwservers
:
Device:/>
add
Address
IPAddress
wwwservers
Address=192.168.10.16
‐
192.168.10.21
Example 4: Deleting an address object
This
example
deletes
an
object
named
wwwsrv1
from
the
address
book:
Device:/>
delete
Address
IPAddress
wwwsrv1
Deleting referenced IP address objects
If
an
IP
address
object
that
is
in
use
by
another
object
is
deleted,
the
deletion
will
appear
to
be
successful.
However,
the
SEG
will
not
allow
the
configuration
to
be
saved
and
will
generate
an
error
message.
You
can
use
the
CLI
‐
references
option
when
displaying
an
IP
address
to
list
references
to
the
address.
For
example,
to
find
all
references
to
the
address
object
sfp1_ip
,
the
CLI
command
is:
Device:/>
show
IPAddress
sfp1_ip
‐
references
Ethernet addresses
Ethernet
Address
objects
are
used
to
define
symbolic
names
for
Ethernet
addresses
(also
known
as
MAC
addresses).
This
is
useful,
for
example,
when
populating
the
ARP
table
with
static
ARP
entries,
or
for
other
parts
of
the
configuration
where
symbolic
names
are
preferred
over
numerical
Ethernet
addresses.
When
specifying
an
Ethernet
address,
use
the
format
aa
‐
bb
‐
cc
‐
dd
‐
ee
‐
ff
.
Ethernet
addresses
are
also
displayed
using
this
format.
