Configuring
High
Availability
Date:
3/
28/12
This
chapter
describes
how
to
configure
high
availability
for
ANM
servers
and
ACE
devices.
Note
When
naming
ACE
objects
(such
as
a
real
server,
virtual
server,
parameter
map,
class
map,
health
probe,
and
so
on),
enter
an
alphanumeric
string
of
1
to
64
characters,
which
can
include
the
following
special
characters:
underscore
(_),
hyphen
(-),
dot
(.),
and
asterisk
(*)
.
Spaces
ar
e
not
al
lowed.
If
you
are
using
ANM
with
an
ACE
module
or
ACE
appliance
and
you
configure
a
named
object
at
the
ACE
CLI,
keep
in
mind
that
ANM
does
not
support
all
of
the
special
characters
that
the
ACE
CLI
allows
you
to
use
when
configuring
a
named
object.
If
you
use
special
characters
that
ANM
does
not
support,
you
may
not
be
able
to
import
or
manage
the
ACE
using
ANM.
