KAL-AP-TAG
Name
Feature
that

is

supported

only

for

the

ACE

module

software

Version

A2(2.0),

ACE

appliance
software
Version

A4(1.0),

and

l

ater

versions

for


both

device

types.

The

KAL-AP-TAG

feature
allows
the

Cisco

Global

Site

Selector

(GSS)

proprietary

KAL-AP

protocol

to

extract

load

and
availability
information

from

the

ACE

when

a

firewall

is

positioned

between

the

GSS

and

the
ACE.
This

feature

allows

you

to

configure

a

tag

(name)

per

VIP

for

a

maximum

of

4096

tags

on
an
ACE.

This

feature

does

not


replace

the

tag

per

domain

feature.

For

more

information

about
this
feature,

see

the

Release

Note

for

the

Cisco

Application

Control

Engine

Module

(Software
Version
A2(2.0))

In
the

KAL-AP-TAG

Name

field,

enter

the

name

as

an

unquoted

text

string

with

no

spaces

and
a
maximum

of

76


alphanumeric

characters.
The
following

scenarios

are

not

supported

and

will

result

in

an

error:

•
You
cannot

configure

a

tag

name

for

a

VIP

that
already
has

a
tag
configuration

as
part
of

a
different
policy

configuration.

•
You
cannot

associate
the
same

tag

name

with

more

than

one

VIP.

•
You
cannot
associate

the

same

tag

name

with

a

domain
and
a

VIP.

•
You
cannot

assign

two

different

tags

to

two

different

Layer
3
class

maps

that

have
the

same
VIP,
but

different

port

numbers.

The

KAL-AP

protocol

considers

these

class

maps

to

have
the
same

VIP

and

calculates

the

load

for

both

Layer

3

rules

together

when

the

GSS

queries
the
VIP.
KAL-AP-Primary-Out-Of-
Service
Feature
that

i

s
supported
only
for

ACE

module

sof

tware

Version

A2(3.1),

ACE

appliance
software
Version

A4(1.0),

and

later

versions

of

either

device

type.

Check

the

checkbox

to

enable
the
ACE

to

notify

a

Global

Site

Selector

(GSS)

that

the

primary

server

farm

is

down

when

the
backup
server

farm

is

in

use.

Uncheck

the

checkbox

to

disable

this

feature.
By
default,

when

you

configure

a

redirect

server

farm

as

a

backup

server

farm

on

the

ACE

and
the
pr

imary

ser

ver

farm

fails,

t

he

backup

server

far

m

redirects

cl

ient

requests

to

another

data
center;
however,

the

VIP

remains

in

the

INSERVICE

state.
When
you

configure

the

ACE

to

communicate

with

a

GSS,

it

provides

information

for

server
availability.
When

a

backup

server

is

in

use

after

the

primary

server

farm

is

down,

this

feature
enables
the

ACE

to

inform

the

GSS

that

the

VIP

for

the

primary

server

farm

is

out

of

service

by
returning
a

load

value

of

255.

The

GSS

recognizes

that

the

primary

server

farm

is

down

and
sends
future

DNS

requests

with

the

IP

address

of

the

other

data

center.
