Important:

File based licensing system (also referred to as manually managed entitlements), traditionally used for activating various on-premises components, will be End of Life (EOL) on April 15, 2026. License Activation Service (LAS) is the next generation technology for product activations across the suite of Citrix products. LAS will be the only way to activate and license NetScaler instances after April 15, 2026, supporting NetScaler Flexed licenses (CPL/UHMC), legacy NetScaler Pooled licenses, and NetScaler Fixed term Bandwidth licenses. To remain supported, your NetScaler and NetScaler Console deployments must be on a LAS compatible version.

The minimum required NetScaler versions that are LAS compatible are:

NetScaler ADCs: 14.1 51.x, 13.1 60.x, 13.1 37.x (FIPS)

NetScaler SVM: 14.1 51.x, 13.1 60.x

NetScaler Console Service: will support LAS from early September.

All the other forms of legacy NetScaler licenses such as Pooled vCPU, CICO, perpetual will not be supported with LAS. NetScaler instances leveraging perpetual licenses without an active maintenance will become unlicensed upon upgrade to the above mentioned software versions.

LAS based licenses may not be available to customers where prohibited by law or regulations.

If you have questions or concerns, contact Customer Care. Citrix may limit or suspend your Citrix Maintenance for non-compliance with these requirements without liability in addition to any other remedies Citrix may have at law or equity. These requirements don’t apply where prohibited by law or regulation.

The license server continuously monitors the health of the NetScaler pooled-capacity enabled instance. The instances communicate through periodical messages to the license server. If few consecutive messages are not received, the license server reports that connectivity has been lost.

You can create custom notifications to supplement the default alarms.

Grace Period

When a NetScaler pooled-capacity enabled instance is in a healthy state and the license server stops responding, the instance continues to operate with the current capacity for 30 days. If the connectivity to the license server is not restored after 30 days, the instance loses its capacity and stops processing traffic.

Notifications and Alarms

Notifications can be enabled from NetScaler Application Delivery Management (ADM) for any action performed on the instance. Apart from the custom notification settings, some alarms are configured by default. For example: To configure an alarm for replenishing a pool that has depleted a certain percentage of its capacity, navigate to Infrastructure > Pooled Licensing and under Notification Settings, click the edit icon.
