Using
the

Configuration

Checkpoint

and

Rollback

Service
At
some

point,

you

may

want

to

modify

your

ACE

running

configuration.

If

you

run

into

a

problem

with
the
modified

configuration,

you

may

need

to

reboot

your

ACE.

To

prevent

having

to

reboot

your

ACE
after
unsuccessfully

modifying

a

running

configuration,

you

can

create

a

checkpoint

(a

snapshot

in

time)
of
a

known

stable

running

configuration

before

you

begin

to

modify

it.

If

you

encounter

a

problem

with
the
modifications

to

the

running

configuration,

you

can

roll

back

the

configuration

to

the

previous

stable
configuration
checkpoint.
Note
Before
you

upgrade

your

ACE

software,

we

strongly
recommend
that
you
cr

eate

a

checkpoint

in
your
running
configuration.

For

ACE

module

A2(3.0)

and

later

releases

only,

use

the

backup

function

to
create
a

backup

of

the

running

configuration

(see

the

“Performing

Device

Backup

and

Restore
Functions”
section

on

pa

ge

6-59 ).
The
ACE

allows

you

to

make

a

checkpoint

configuration

at

the

context

level.

The

ACE

stores

the
checkpoint
for

each

context

i

n

a

hi

dden

di

rectory

in

Flash

memory.

If,

after

you

make

configuration
changes
that

modify

the

current

running

configuration,

when

you

rol

l

back

t

he

checkpoint,

the

ACE
causes
the

running

configuration

to

revert

to

the

checkpointed

configuration.
