Hello All
I have client that want to use the CSS to loadbalance only to thier active server and if that server fails then send requests to the standby server.
I have told them that using the CSS to acomplish this is not the best use of it functionallity but they want to do it anyway. Does anybody know how this can be done.
I know the CSS will send keepalives to the particular service to ensure it is available and was wondering if I could use these to detect the primary server failure and then start sending traffic to the secondary.
I do not want to loadbalance to both servers I only want to forward traffic to the secondary server if the primary fails.

Hi,
you can accomplish this by using a sorryserver.
configure you content rule, add your active service using "add service server1" and add you standby service (which will be only used when the active service goes down) using "primarySorryServer server2".
See the config guide for more info: http://www.ciscopress.info/en/US/docs/app_ntwk_services/data_center_app_services/css11500series/v7.40/configuration/content_lb/guide/contrule.html#wp1038009

Hi Dario
This looks like exactly what I am looking for.
Thanks for your help.

Paul-
One way you could almost do it is to assign a high weight to the 'active' and a low weight to the 'passive' one.
Weight is a value assigned to an SP based on its ability to provide session processing. An active SP has a relative weight assignment greater than 0. A weight of 0 prevents the SP from performing any session processing.
service ldaps-server-1
port 636
redundant-index 1031
ip address 10.10.201.127
keepalive type none
weight 10
service ldaps-server-2
port 636
redundant-index 1031
ip address 10.10.201.128
keepalive type none
weight 1
Hope it helps.
