Configure Citrix ADC pooled capacity 编辑

To use ADC pooled capacity, configure Citrix ADM as a license server to the required ADC instances. ADC instances check in and check out licenses from the ADM. You can perform the following tasks in the ADM GUI:

• Upload the pooled capacity license files (bandwidth and instance pool) to the license server.

• Allocate licenses from the license pool to Citrix ADC instances on demand.

• Check out the licenses from Citrix ADC instances (MPX-Z /SDX-Z/VPX/CPX/BLX) based on the minimum and maximum capacity of the instance.

• Configure pooled capacity for Citrix ADC FIPS instances to check in or check out licenses.

Supported hardware and software versions

For supported hardware and software versions for pooled capacity, see Citrix ADC pooled capacity.

ADC pooled capacity states

The pooled capacity states indicate the license requirement on an ADC instance. The ADC instances configured with pooled capacity display one of the following states:

• Optimum: Instance is running with proper license capacity.

• Capacity mismatch: Instance is running with a capacity less than the user configured.

• Grace: Instance is running on a grace license.

• Grace & Mismatch: Instance is running on grace but with a capacity less than the user configured.

• Not available: Instance is not registered with ADM for management, or NITRO communication from ADM to the instances is not working.

• Not allocated: License is not allocated in the instance.

Step 1 - Apply licenses in ADM

1. In Citrix ADM, navigate to Infrastructure > Pooled Licensing.

2. In the License Files section, select Add License File and select one of the following options:

   • Upload license files from a local computer. If a license file is already present on your local computer, you can upload it to ADM.

   • Use license access code. Specify the license access code for the license that you have purchased from Citrix. Then, select Get Licenses. Then select Finish.

   Note

   At any time, you can add more licenses to ADM from License Settings.

3. Click Finish.

   The license files are added to ADM. The License Expiry Information tab lists the licenses present in the ADM and the remaining days to expiry.

4. In License Files, select a license file that you want to apply and click Apply licenses.

   This action enables ADC instances to use the selected license as a pooled capacity.

Step 2 - Register Citrix ADM as a license server

To register ADM as a license server to a Citrix ADC instance, follow one of the procedures:

• Use GUI
• Use CLI

Use GUI to register ADM as a license server

In the ADM GUI, register the ADM server as a license server.

1. Log in to Citrix ADC GUI.

2. Navigate to System > Licenses > Manage Licenses.

3. Click Add New License.

4. Select Use remote licensing and select the remote licensing mode from the list.

5. In the Server Name/IP address field, specify the ADM server’s IP address.

6. Select Register with Citrix ADM.

7. Enter your ADM credentials to register an instance with Citrix ADM and click Continue.

   

8. In Allocate licenses, select the license edition and specify the required bandwidth.

   For the first time, allocate licenses in Citrix ADC. You can later change or release the license allocation from the ADM GUI.

   

9. Click Get Licenses.

   Important

   Warm restart the instance if you change the license edition. The configuration changes do not take effect until you restart the instance.

Use CLI to add ADM as a license server

If an ADC instance has no GUI, use the following CLI commands to add the ADM server as a license server:

1. Log in to the ADC console.

2. Add the ADM server IP address:

   > add ns licenseserver <adm-server-IP-address> -port <adm-server-port-number> -licensemode <license-mode>
