Dynamic
Workload

Scaling—ACE

feature

that

permits

on-demand

access

to

remote

resources,

such
as
VMs,

that

you

own

or

lease

from

an

Internet

service

provider

(or

cloud

service

provider).

This
feature
uses

Cisco’s

Nexus

7000

series

switches

with

Cisco’s

Overlay

Transport

Virtualization
(OTV),
which

is

a

Data

Center

Interconnect

(DCI)

technology

used

to

create

a

Layer

2

link

over

an
existing
IP

network

between

geographically

distributed

data

centers.
For
more

information,

see

the

“Dynamic

Workload

Scaling

Overview”

section

on

Note
Dynamic
Workload
Scaling

requires

ACE

module

or

appliance

software

Version
A4(2.0)
or
later
and

the

Cisco

Nexus

7000

Series

switch.

pl

ug-in
for
vCenter

Ser

ver—Enabling

the

pl

ug-in

on

an


ANM

server

or

ANM

Virtual
Appliance
permits

access

to

ANM’s

ANM
Mobile—Feature

that

enables

supported

mobile

devices

to

access

to

your

ANM

server
or
ANM
Virtual

Appliance,

allowing

you

to

manage

the

network

objects

in

much

the

same

way

you

do
from
an

ANM

client.

Using

a

mobile

device,

you

can

run

ANM

Mobile

as

a

native

application

or
inside
the

mobile

device’s

browser.

IPv6
Considerations
Beginning
with

ACE

software

Version

5.1,

the

ACE

supports

IPv6

configurations,

which

you

can
configure
using

ANM

beginning

with

ANM

software

Version

5.1.
The
ACE

supports

IPv6

configurations

with

the

following

considerations:

•
All
the

management

traffic

used

by

ANM

is
required
to

send

over

IPv4

protocol.

IPv6

is

not
supported.

•
By
default,

IPv6
is
disabled
on
an
interface.

You
must

enable

IPv6

on

the

interface

to

enable

its
configured
IPv6

addresses.

The

interface

cannot

be

in

bridged

mode.

The

interface

may

or

may

not
have
IPv4

addresses

configured

on

i

t.

•
When
you

enable

IPv6

or

configure

a

global

IPv6

address

on

an
interface,
the

ACE

automatically
does
th

e

f

ollowing:

–

Configures

a

link-local

address

(i

f

it

is

not


already

configured)

–

Performs

duplicate

address

detection

(DAD)

on

both

addresses
You
must

enable

IPv6

on

the

interface

to

enable

global

IPv6

address.

•
IPv6
on

interface

can

be
individually
enabled
or

disabled.

IPv6

cannot

be
enabled
or

disabled
globally.

•
A
link-local

address

is

an

IPv6

unicast

address

that

has

a

scope

of

the

local

link

only

and

is

required
on
every

interface.

Every

link-local

address

has

a

predefined

prefix

of

FE80::/10.

You

can

configure
a
link-local

address

manually.

If

you

do

not

configure

a

link-local

address

before

enabling

an

IPV6
address
on

the

interface,

the

ACE

automatically

generates

a

link-local

address

with

a

prefix

of
FE80::/64.
Only

one

IPv6

link-local

address

can

be

configured

on

an

interface.
In
a

redundant

configuration,

you

can

configure

an

IPv6

peer

link-local

address

for

the

standby

ACE.
You
can

configure

onl

y

one

peer

link-local

address

on

an

interface.
