Licensing overview 编辑

Citrix offers a wide range of product editions and licensing models for MPX and VPX appliances, to meet your organization’s need.

For proper operation of a Citrix ADC appliance, it must have one of the Citrix ADC family edition licenses. The ADC product line has three family editions:

• Standard Edition
• Advanced Edition
• Premium Edition

For more information, see the Citrix ADC data sheet.

Select a Citrix ADC edition. Then select an MPX or a VPX license offering based on the following criteria:

• Perpetual and subscription (yearly and hourly subscription)
• vCPU and bandwidth
• on-premises and cloud

Citrix ADC VPX Express license

VPX Express for on-premises and cloud deployments does not require a license file, and it offers the following features:

• 20 Mbps bandwidth
• All ADC standard license features, except Citrix Gateway and L4 and L7 defenses
• Maximum 250 SSL sessions
• 20 Mbps SSL throughput

You can upgrade the VPX Express License to the following two options:

1. A standalone Citrix ADC VPX license

2. Citrix ADC Pooled Capacity license for VPX instances. For more information, see Citrix ADC Pooled Capacity.

Important

Clustering is available in Standard edition for VPX public cloud, and in VPX Express license.

Citrix ADC Pooled Capacity license

Use Citrix Application Delivery Management (ADM) to create a licensing framework that comprises a common bandwidth and an instance pool. For more information, see Citrix ADC Pooled Capacity.

Note:

Citrix ADM can host both Pooled and Self Managed Pool licenses. To use the required license, configure the license server on Citrix ADC and check out the capacity from the appropriate pool. The ADC CLI and GUI configuration steps for Pooled and Self Managed Pool license are the same.

Citrix ADC Self Managed Pool license

From Citrix ADC release 13.0 build 88.x, Citrix ADC instances support Self Managed Pool license. With this license, you can simplify and automate license file uploads to license server. Use Citrix ADM to create a licensing framework that comprises a common bandwidth or vCPU and instance pool.

To use the Self Managed Pool license, configure the license server to the SelfManagedPool license mode on Citrix ADC and check out the required capacity. Use the show ns license command after rebooting the Citrix ADC appliance to find out the license that is configured.

Important

If your system is configured with Pooled Capacity license but want to migrate to Self Managed Pool license without impacting the traffic flow, ensure that the target server has the required Self Managed Pool license.

You can migrate only between the following compatible licenses:

• Pooled Capacity to Self Managed Pool, and conversely.
• vCPU to Self Managed vCPU, and conversely.

To migrate the license, run the following command:

add ns licenseserver (<licenseServerIP> | <serverName>) -forceUpdateIP -licensemode [CICO | Pooled | SelfManagedPool | VCPU | SelfManagedvCPU]

Example:

add licenseserver 192.0.2.246 -forceUpdateIP -licensemode selfManagedvcPU

Configure Self Managed Pool license using the CLI

To add license server config to the Citrix ADC appliance, run the following command:

add ns licenseserver (<licenseServerIP> | <serverName>) [-port <positive_integer>] -licensemode [CICO | Pooled | SelfManagedPool | VCPU | SelfManagedvCPU]
