**HOW DO I GENERATE THE CSR ON THE ARUBA CONTROLLER?**

CSR can be generated only on ArubaOS 3.x.x.x and later. However for ArubaOS 2.5.x.x, you can use tools like OpenSSL to generate the CSR and private key on behalf of the controller. You can also use VeriSign to generate a server certificate without CSR.

 

**Using the WebUI to generate a CSR (ArubaOS 3.x):**

 

1. **Navigate to Configuration > Management > Certificates > CSR**.

2. **Click Generate New.**

3. **Enter the information requested, such as country and key length.**

4. **Click View Current to display the generated CSR.**

5. **Select and copy the CSR output between the BEGIN CERTIFICATE REQUEST and END CERTIFICATE REQUEST lines, paste it into an email, and send it to the CA of your choice.**

 

**Using the CLI to generate a CSR (ArubaOS 3.x):**

 

1. Enter the following command:

crypto pki csr key {1024|2048|4096}

common-name <value> country <country> state_or_province <state> city <city> organization <org> unit <string> email <email>

2. Display the CSR output by entering the following command:

show crypto pki

csr

3. Copy the CSR output between the BEGIN CERTIFICATE REQUEST and END CERTIFICATE REQUEST lines, paste it into an email, and send it to the CA of your choice.
