ACE : Alternate configuration for NCI-TYPE-INFO only

rajesh.perumalla · ‎11-06-2008

Hi,

Is there a way to configure redirect type NCI-TYPE-INFO only - on the ACE devices ?

I need this functionality to redirect the traffic when the servers at the primary site are down and the clients still hit the content at site 1

The CSS config is

service 1

ip address a.a.a.a

active

service 2

ip address a.a.a.b

active

service site2

ip address Y.Y.Y.Y(Vip address of the remote site)

type NCI-INFO-ONLY

active

content

vip X.X.X.X

add service 1

add service 2

primarysorryserver service site2

active

source group redirect

vip address X.X.X.X

add destination service site 2

active

and similar configuration at Remote CSS.

Thanks in Advance.

Raj

Something like this should do

rserver Site1-Server1

ip address a.a.a.a

inservice

rserver Site1-Server2

ip address a.a.a.b

inservice

rserver Site2-Server

ip address Y.Y.Y.Y

inservice

serverfarm host Site1-SF

probe ICMP

rserver Site1-Server1

inservice

rserver Site1-Server2

inservice

serverfarm host Site2-SF

probe ICMP

rserver Site2-Server

inservice

policy-map type loadbalance first-match APP1-policy-map

class class-default

serverfarm Site1-SF backup Site2-SF

nat dynamic 1095 vlan x serverfarm primary

interface vlan x

ip address

access-group input ANYONE

nat-pool 1095 x.x.x.x x.x.x.x netmask 255.255.255.0 pat

service-policy input VLANX-VIPS

no shutdown

Thanks for the reply..

From the above config

"nat dynamic 1095 vlan x serverfarm primary"

Will this statement does the source NAT for the clients hitting Primary Serverfarm or both primary and backup server farms ?

I am aiming for the configuration that does SNAT only for cliet hitting the serverfarm Site2-ST .

Please advice the related config.

My bad it will do it for primary only change it to

nat dynamic 1095 vlan x serverfarm backup
