ACE
Redundancy
–
If
the
License
Compatibility
field
indicates
a
licensing
problem,
go
to
the
Licenses
page
of
ACE
Hardware
Setup
(see
the
“Using
ACE
Hardware
Setup”
section
on
page
3-5
)
and
make
sure
each
ACE
device
has
a
valid
license
installed.
Licenses
must
be
installed
on
each
device
separately
because
each
license
is
only
valid
for
one
hardware
device.
For
proper
HA
functionality,
the
licenses
on
both
ACEs
in
the
pair
must
be
also
compatible
with
each
other.
This
means
both
licenses
must
permit
the
same
bandwidth
and
the
same
number
of
virtual
contexts.
Note
If
the
licenses'
bandwidth
limits
do
not
match,
configuration
synchronization
may
appear
to
work
(although
Admin
context
synchronization
may
actually
not
be
functional),
and
the
License
Compatibility
field
may
not
show
an
er
ror.
However,
failover
from
the
higher
bandwidth
ACE
to
a
lower
bandwidth
ACE
could
result
in
l
oss
of
t
raffic.
