Feature
that

applies

only

to

the

ACE

module

A2(1.1),

ACE

appliance

A4(1.0),

or

later

releases
of
either

device

type.

Choose

Switch

Mode

to

change

the

way

that

the

ACE

processes

TCP
connections
that

are

not

destined

to

a

VIP

or

that

do

not

have

any

policies

associated

with

their
traffic.
For

such

traffic,

the

ACE

still

creates

connection

objects

but

processes

the

connections
as
stateless

connections,

which

means

that

they

do

not


undergo

any

TCP

no

rmalization
checks.
With

this

option

enabled,

the

ACE

also

cr

eates

stateless

connections

for


non-SYN
TCP
packets

if

they

satisfy

all

other

configured

requirements.

This

process

ensures

that

a
long-lived
persistent

connection

passes

through

the

ACE

successfully

(even

if

it

times

out)

by
being
reestablished

by

any

incoming

packet

related

to

the

connection.
By
default,

these

stateless

connections

time

out

af

ter

2

hours

and

15

mi

nutes

unless

you
configure
the

inactivity

timeout

otherwise

in

a

parameter

map.

When

a

stateless

connection
times
out,

the

ACE

does

not

send

a

TCP

RST

packet

but

silently

closes

the

connection.

Even
though
these

connections

are

stateless,

the

TCP

RST

and

FIN-ACK

flags

are

honored

and

the
connections
are

closed

when

the

ACE

sees

these

flags

in

the

received

packets.
