Synchronizing

ACE

High

Availability

Configurations

When

two

ACE

devices

are

configured

as

high

availability

peers,

their

configurations

must

be

synchronized

at

all

times

so

that

the

standby

member

can

take

over

for

the

active

member

seamlessly.

As

they

synchronize,

however,

the

configuration

on

the

hot

standby

ACE

can

become

out

of

sync

with

the

ANM-maintained

configuration

data

for

that

ACE.

Note

ANM

manages

local

configurations

only.
