Secure

KAL-AP
You
can

configure

a

secure

keepalive-appliance

protocol

(KAL-AP)

associated

with

a

virtual

context.

A
KAL-AP
on

the

ACE

enables

communication

between

the

ACE

and

a

Global

Site

Selector

(GSS),

which
sends
KAL-AP

requests

to

report

the

ser

ver

states

and

loads

for

gl

obal-server

load-balancing

(GSLB)
decisions.
The

ACE

uses

KAL-AP

through

a

UDP

connection

to

calculate

weights

and

provide
information
for

server

availability

to

the

KAL-AP

device.

The

ACE

acts

as

a

server

and

listens

for
KAL-AP
requests.

When

KAL-AP

is

initialized

on

the

ACE,

the

ACE

listens

on

the

standard

5002

port
for
any

KAL-AP

requests.

You

cannot

configure

any

other

por

t.
The
ACE

supports

secure

KAL-AP

for

MD5

encryption

of

data

between

it

and

the

GSS.

For

encryption,
you
must

configure

a

shared

secret

as

a

key

for

authentication

between

the

GSS

and

the

ACE

context.
