Expect

Status
You
can

configure

a

single

or

range

of

code

responses

that

the

ACE

expects

from

the

probe

destination.
When
the

ACE

receives

a

response

from

the

server,

it

expects

a

status

code

to

mark

a

server

as

passed.
By
default,

there

are

no

status

codes

configured

on

the

ACE.

If

you

do

not

configure

a

status

code,

any
response
code

from

the

server

is

marked

as

failed.
