NetScaler BLX licensing

Licensing a Citrix ADC BLX appliance expands the capability and performance of the appliance. By default, a BLX appliance comes with an express license. You can upgrade an express license to a subscription-based local license that has a term date, or to a Citrix ADC pooled capacity license stored in a Citrix ADM appliance.

NetScaler BLX license types

By default, all BLX appliances come with an express license. A BLX with an express license has the following features:

• 20 Mbps bandwidth
• Web Logging, Load Balancing, Content Switching, Cache Redirection, SSL Offloading, Content Filtering, Rewrite, IPv6 protocol translation, Responder, AppFlow, Clustering, and Call Home
• Maximum 250 SSL sessions
• 20 Mbps SSL throughput

Expand the capability and performance of a BLX appliance running with an express license by upgrading the license to one of the following options:

• Subscription-based local licenses. A Local license is similar to a perpetual license however they have an expiration date.
• Citrix ADC pooled capacity licenses in Citrix ADM. For more information, see Citrix ADC Pooled Capacity.
• Citrix ADC check-in and check-out (CICO) licenses in Citrix ADM. You can allocate licenses to BLX appliances on-demand from Citrix ADM. The ADM software stores and manages the licenses, which have a licensing framework that provides scalable and automated license provisioning. A BLX appliance can check out the license from the Citrix ADM when a BLX appliance is deployed. When a BLX appliance is removed or destroyed, the appliance checks back its license to the Citrix ADM software.

Subscription-based local licenses for NetScaler BLX appliances

A Local license is similar to a perpetual license however they have an expiration date. The software subscription that makes up local licenses are term-based and can be installed without requiring ADM as a licensing server.

The following type of subscription local licenses is available for BLX appliances:

• Bandwidth-based subscription-based local license. This type of license is enforced with a maximum allowed throughput that a particular BLX appliance is entitled to.

Each local license is also tied up with one of the Citrix ADC software editions: Standard, Enterprise, or Platinum, which unlocks the ADC feature set of this edition in a BLX appliance. Embedded Select support is included with the subscription local license purchase.

Example:

A BLX Subscription 10 Gbps Premium Edition entitles a BLX appliance with a maximum allowed throughput of 10 Gbps. This license also unlocks all the ADC features, listed in the Premium edition, in the BLX appliance.

Note:

Standard edition has reached End-of-Sale (EOS) and is only available for renewal.
