Configuration for LSN parameter resource.

Properties (click to see Operations)

Name Data Type Permissions Description
memlimit
<Double>
Read-write
Amount of NetScaler memory to reserve for the LSN feature, in multiples of 2MB.

Note: If you later reduce the value of this parameter, the amount of active memory is not reduced. Changing the configured memory limit can only increase the amount of active memory.
This command is deprecated, use 'set extendedmemoryparam -memlimit' instead.
sessionsync
<String>
Read-write
Synchronize all LSN sessions with the secondary node in a high availability (HA) deployment (global synchronization). After a failover, established TCP connections and UDP packet flows are kept active and resumed on the secondary node (new primary).

The global session synchronization parameter and session synchronization parameters (group level) of all LSN groups are enabled by default.

For a group, when both the global level and the group level LSN session synchronization parameters are enabled, the primary node synchronizes information of all LSN sessions related to this LSN group with the secondary node.
Default value: ENABLED
Possible values = ENABLED, DISABLED
subscrsessionremoval
<String>
Read-write
LSN global setting for controlling subscriber aware session removal, when this is enabled, when ever the subscriber info is deleted from subscriber database, sessions corresponding to that subscriber will be removed. if this setting is disabled, subscriber sessions will be timed out as per the idle time out settings.
Default value: DISABLED
Possible values = ENABLED, DISABLED
memlimitactive
<Double>
Read-only
Amount of actual memory reserved for the LSN feature.

The amount of active memory for the LSN feature might be less than the configured memory, because the available memory is shared across features.
maxmemlimit
<Double>
Read-only
Maximum amount of NetScaler memory that can be reserved for the LSN feature.

Operations (click to see Properties)

Some options that you can use for each operations:

  • Getting warnings in response: NITRO allows you to get warnings in an operation by specifying the "warning" query parameter as "yes". For example, to get warnings while connecting to the NetScaler appliance, the URL is as follows:

    http://<netscaler-ip-address>/nitro/v1/config/login?warning=yes

    If any, the warnings are displayed in the response payload with the HTTP code "209 X-NITRO-WARNING".

  • Authenticated access for individual NITRO operations: NITRO allows you to logon to the NetScaler appliance to perform individual operations. You can use this option instead of creating a NITRO session (using the login object) and then using that session to perform all operations,

    To do this, you must specify the username and password in the request header of the NITRO request as follows:

    X-NITRO-USER:<username>

    X-NITRO-PASS:<password>

    Note: In such cases, make sure that the request header DOES not include the following:

    Cookie:NITRO_AUTH_TOKEN=<tokenvalue>
