Citrix ADC

Overriding LSN configuration with Load Balancing Configuration

An LSN configuration takes precedence over any load balancing configuration by default. For overriding the large scale networking (LSN) configuration with the load balancing configuration for traffic matching both configurations, create a net profile with Override LSN parameter enabled and bind this profile to the virtual server of the load balancing configuration. USNIP or USIP settings of the load balancing configuration are applied to the traffic, instead of applying the LSN IP address of the LSN configuration.

This option is useful in an LSN deployment that includes Citrix ADC appliances and value added services, such as firewall and optimization devices. In this type of deployment, the ingress traffic on the Citrix ADC appliance is required to pass through these value-added services before an LSN configuration on the appliance is applied to the traffic. For the Citrix ADC appliance to send the ingress traffic to a value added service, a load balancing configuration is created and override LSN is enabled on the appliance. The load balancing configuration includes value added services, represented as load balancing services, bound to a virtual server of type ANY. The virtual server is configured with listen policies for identifying the traffic to be sent to the value added service.

To enable override lsn in a net profile by using the CLI

To enable override lsn while adding a net profile, at the command prompt, type

add netProfile <name> -overrideLsn ( ENABLED | DISABLED )

show netprofile <name>
<!--NeedCopy-->

To enable override lsn while adding a net profile, at the command prompt, type

set netProfile <name> -overrideLsn ( ENABLED | DISABLED )

show netprofile <name>
<!--NeedCopy-->

To enable override lsn in a net profile by using GUI

Navigate to System > Network > Net Profiles.
Set the Override LSN parameter while adding or modifying net profiles.

In the following sample configuration, net profile NETPROFILE-OVERRIDELSN-1 has override LSN option enabled and is bound to load balancing virtual server LBVS-1.

Sample configuration:

add netprofile NETPROFILE-OVERRIDELSN-1 -overrideLsn ENABLED

Done

set lb vserver LBVS-1 -netprofile NETPROFILE-OVERRIDELSN-1

Done
