Configuring Backup Persistence

Nov 23, 2015

The NetScaler appliance uses backup persistence to choose a new type of persistence when the primary persistence type fails. For example, if the primary persistence type is set to Cookie Insert, and backup persistence is set to Source IP, the NetScaler appliance uses Source IP-based persistence when the cookie is missing from the HTTP header or when the client browser does not support cookies.

You can set a time-out value for backup persistence only when the primary persistence type is HTTP Cookie-based or RTSP session ID-based persistence, and the backup persistence type is Source IP-based.

To set backup persistence for a virtual server by using the command line interface

At the command prompt, type:

set lb vserver <name> -persistenceType <PersistenceType> -persistenceBackup <BackupPersistenceType>

Example

set lb vserver Vserver-LB-1 -persistenceType CookieInsert -persistenceBackup SourceIP

To set backup persistence for a virtual server by using the configuration utility

  1. Navigate to Traffic Management > Load Balancing > Virtual Servers, and open the virtual server.
  2. In Advanced Settings, select Persistence, and specify a backup persistence type.
